app.config file in C# project

app config under solution app.config

1. How to: Add an application configuration file to a C# project

By adding an application configuration file (app.config file) to a C# project, you can customize how the common language runtime locates and loads assembly files. For more information about application configuration files, see How the runtime locates assemblies (.NET Framework)..

When you build your project, the development environment automatically copies your app.config file, changes the file name of the copy to match your executable, and then moves the copy to the bin directory.

2. Configuration file schema for the .NET Framework

Configuration files are standard XML files that you can use to change settings and set policies for your apps. The .NET Framework configuration schema consists of elements that you can use in configuration files to control the behavior of your apps. The table of contents for this section reflects the schema hierarchy for startup, runtime, network, and other types of configuration settings.

For information about the types, format, and location of configuration files, see Configure apps. Familiarize yourself with XML if you want to edit the configuration files directly.

3. Configuring Apps by using Configuration Files

The .NET Framework, through configuration files, gives developers and administrators control and flexibility over the way applications run. Configuration files are XML files that can be changed as needed. An administrator can control which protected resources an application can access, which versions of assemblies an application will use, and where remote applications and objects are located. Developers can put settings in configuration files, eliminating the need to recompile an application every time a setting changes. This section describes what can be configured and why configuring an application might be useful..

4. Manage application settings (.NET)

Application settings enable you to store application information dynamically. Settings allow you to store information on the client computer that should not be included in the application code (for example a connection string), user preferences, and other information you need at run time.

Application settings replace the dynamic properties used in earlier versions of Visual Studio.

6. Windows Forms Add Configuration Element

The <add > element adds a predefined key that specifies whether your Windows Form app supports features added to Windows Forms apps in the .NET Framework 4.7 or later.

7. High DPI support in Windows Forms

Starting with the .NET Framework 4.7, Windows Forms includes enhancements for common high DPI and dynamic DPI scenarios. These include:

1. Improvements in the scaling and layout of a number of Windows Forms controls, such as the MonthCalendar control and the CheckedListBox control.
2. Single-pass scaling. In the .NET Framework 4.6 and earlier versions, scaling was performed through multiple passes, which caused some controls to be scaled more than was necessary.
3. Support for dynamic DPI scenarios in which the user changes the DPI or scale factor after a Windows Forms application has been launched.

In versions of the .NET Framework starting with the .NET Framework 4.7, enhanced high DPI support is an opt-in feature. You must configure your application to take advantage of it..

8. Windows Forms Configuration Section

Windows Forms configuration settings allow a Windows Forms app to store and retrieve information about customized application settings such as multi-monitor support, high DPI support, and other predefined configuration settings.

Windows Forms application configuration settings are stored in an application configuration file's System.Windows.Forms.ApplicationConfigurationSection element...

3. High DPI Support in Windows Forms Discusses Windows Forms' support for High DPI and dynamic scaling.
10. Changing the Appearance of Windows Forms

You can customize the look of your Windows Forms applications in many different ways, such as changing the border, opacity, shape, style, or setting a background image for your Windows Forms application..

11. How to: Change the Borders of Windows Forms

You have several border styles to choose from when you are determining the appearance and behavior of your Windows Forms. By changing the FormBorderStyle property, you can control the resizing behavior of the form. In addition, setting the FormBorderStyle affects how the caption bar is displayed as well as what buttons might appear on it. For more information, see FormBorderStyle..

12. App.Config: Basics and Best Practices

In one of my previous posts, I wrote about the .NET build configuration system. I mentioned the app.config file, but didn’t really dive into it. So let’s take a closer look at this file now. When you create a (non-web) .NET Framework application in Visual Studio, an app.config file is added to your project. When you create a class library or a .NET Core project, such a file is not included, although it can be done afterward..

13. What is App.config in C#.NET? How to use it?

20. Web.config Vs App.config Vs Machine.config

will let you know why we use it. As you know all are configuration files which are used to store the data which would be key –value.

As per security purpose this data is known as secure data because it cannot be hacked by some external resource directly. So, let's start one by one to know more about these configuration files...

21. Multiple App.config in a Solution

Symptom: You get the following pop-up message that prompts you to check your application configuration:

“The request could not be performed because required configuration settings are missing. Please contact your administrator to fetch the latest configurations files”.

Solution: This issue occurs due to the presence of multiple App.config files in the solution. The App.config that holds all the required configuration for a GWM based solution to work is stored inside the SAP Service Reference folder under the project file. For running a GWM based solution you need to either have only one App.config file, or specifically load the GWM config file as and when needed..

22. .NET/.NET Core

.NET is a free, cross-platform, open-source developer platform for building many different types of applications..

solution file in C# project

1. Create, work with, and delete Visual Studio projects and solutions

In this article, you'll learn how to create and use Visual Studio projects from scratch to store the artifacts you need to build your apps. If you aren't familiar with projects in Visual Studio, see this overview of Projects and Solutions. To learn how to quickly create a project from a template, see Create a project from a template.

Projects hold the items needed to build your app in Visual Studio, such as source code files, bitmaps, icons, and component and service references. When you create a new project, Visual Studio creates a solution to contain the project. You can then add other new or existing projects to the solution if you want. You can also create blank or empty solutions. Solutions can also contain files that aren't connected to any specific project..

2. image upload

good srevice to use.

3. Creating and editing solution files with the .NET CLI

With the release of Visual Studio 2017 and the RTM .NET Core tooling, the .NET command line has gone through a transformation. The project.json format is no more, and instead we have returned back to .csproj files. It's not your grand-daddy's .csproj however - the new .csproj is far leaner than previous MSBuild files, and massively reduces the reliance on GUIDs.

One of the biggest reasons for this is the need to make the files easily editable by hand. With .NET Core being cross platform, relying on Visual Studio to edit the files correctly with the magic GUIDs is no longer acceptable.

4. Chapter 1. Solutions and Projects

Solutions A solution contains a collection of projects, along with information on dependencies between those projects. The projects themselves contain files. This structure is illustrated in Figure 1-1. You can have as many projects as you like in a solution, but there can be only one solution open at a time in a particular instance of VS.NET. (You can, of course, open multiple solutions by running multiple instances of VS.NET.).

5. Generate Solution File From List of CSProj

How to create solution file in visual studio 2017 for existing project Create solutions and projects, Create a solution · Open Visual Studio. · On the top menu bar, choose File > New > Project. The New Project dialog box opens. · In the left pane, The first thing you need to do with Visual Studio is click File/New Project. Name it whatever you would like and choose the directory where you want the solution file to exist. Under ‘Installed Templates’, choose ‘Other Project Types/Visual Studio Solutions’. The only item in the main window should be ‘Blank Solution.

pay attention to web socket. it can be used to get real-time streaming data

22. How to stream the data

There are several options for obtaining the data in Twelve Data. They can be divided into two categories: long-polling via API and server-push via WebSocket. In the second scenario, the server will automatically send the data to the client once it is available, so the client will always stay with the latest information.

This tutorial will cover establishing the connection and start receiving the data in a few easy steps.
1. Open a connection.
2. Send subscribe event.
3. Manipulate the data.
4. Close the connection.

You can use any programming language or plugin of your choice. Here for the sake of simplicity, we will be using the WebSocket playground.

23. WEb socket document:

WebSocket will automatically send the data to you once a new piece of data is available on the exchange. In the beginning, you need to establish a connection between the server and the client. Then all data is controlled by sending event messages to the server. WebSocket is opposed to the API, where the data has to be explicitly requested from the server.

You may use the API key to connect to the Twelve Data Distributed WebSocket System (TDDWS). This system will manage all your requests to all available instruments across different exchanges. You can establish up to 3 connections (typically used in production, stage, and local environments) across the whole lifespan of the application; if you open more, the previous connections will be closed.

You may subscribe to all symbols available at Twelve Data; meanwhile, the format remains the same as the API unless there are constraints in the endpoint. Moreover, you may combine symbols across different types, and TDDWS will manage the routing. There are some limitations, though:

OEM version installation

key#:microsoft oem preinstallation tools windows 10

1. What are OEM pre-installation tools

I just purchased a windows 10 OEM system builder DVD from amazon, for use on a custom built PC, and am unsure of what this bit of text on the front of the DVD package means:.

FWIW I've installed a lot of OEM versions of Windows 7 and never had to deal with any kind of pre-installation packs. I did have to make sure I had all the right drivers from the makers of my motherboard and any additional hardware I added. With Windows 10 though I just download the insider builds on my desktops, and my laptop came with 10 pre-installed.

2. Do i need to format my drives before i install windows

Not manually, no.

Windows will do the necessary formatting as part of the installation process.

Disconnect all drives other than the 1 to receive Windows before you begin..

5. USB Drive Formats For Windows 10 Installation Media

Do we have to format USB drives to FAT32 format to create Windows 10 installation media like we do with USB drives we use for BIOS updates?

I read through the instructions on Microsoft's website, and it doesn't seem to specify. My motherboard manual didn't specify either, but it didn't work when I didn't format to fat32 and it worked the 2nd time using a different USB that I formatted to fat32... so this is why I'm asking..

6. Can I use OEM Windows Server 2019?

have bought a used server and looking to install Windows Server 2019 Standard on it. I have looked online and I cannot, for the life of me, find Windows Server 2019 Std RETAIL.

As such, can I legitimately buy Windows Server 2019 OEM and use it on a used server and still be covered by Microsoft Licensing?

The Rete algorithm (/ˈriːtiː/ REE-tee, /ˈreɪtiː/ RAY-tee, rarely /ˈriːt/ REET, /rɛˈteɪ/ reh-TAY) is a pattern matching algorithm for implementing rule-based systems. The algorithm was developed to efficiently apply many rules or patterns to many objects, or facts, in a knowledge base. It is used to determine which of the system's rules should fire based on its data store, its facts. The Rete algorithm was designed by Charles L. Forgy of Carnegie Mellon University, first published in a working paper in 1974, and later elaborated in his 1979 Ph.D. thesis and a 1982 paper.[1].

__stdcall

calling convention explained

1. Calling Conventions Demystified

Visual C++ calling conventions explained.

2. Calling Conventions

Calling Conventions. good history.

3. x86 Disassembly/Calling Conventions

Calling conventions are a standardized method for functions to be implemented and called by the machine. A calling convention specifies the method that a compiler sets up to access a subroutine. In theory, code from any compiler can be interfaced together, so long as the functions all have the same calling conventions. In practice however, this is not always the case..

4. __stdcall

The __stdcall calling convention is used to call Win32 API functions. The callee cleans the stack, so the compiler makes vararg functions __cdecl. Functions that use this calling convention require a function prototype. The __stdcall modifier is Microsoft-specific..

The /Gz compiler option specifies __stdcall for all functions not explicitly declared with a different calling convention.

For compatibility with previous versions, _stdcall is a synonym for __stdcall unless compiler option /Za (Disable language extensions) is specified.

5. what does WINAPI stand for

I've started to learn Win32 API in C. I saw that the main function is something like

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { .. }

but I know that a function in C is like

[ReturnType] [FunctionName] (Args) { .. }
In this case the return type is int and the function name is WinMain. So what does the WINAPI stand for and is it necessary?.
6. Using Win32 calling conventions

When writing code for the Win32 platform, most developers don't pay attention to selecting a "calling convention", and in most cases it doesn't really matter much. But as systems get larger and split into more modules (especially when third-party modules are to be included), this becomes something that cannot really be ignored..

In this Tech Tip, we discuss what the MSVC calling conventions are, why to choose one over the other, and "big system" considerations that may not be obvious.

7. Intel x86 Function-call Conventions - Assembly View

One of the "big picture" issues in looking at compiled C code is the function-calling conventions. These are the methods that a calling function and a called function agree on how parameters and return values should be passed between them, and how the stack is used by the function itself. The layout of the stack constitutes the "stack frame", and knowing how this works can go a long way to decoding how something works.

In C and modern CPU design conventions, the stack frame is a chunk of memory, allocated from the stack, at run-time, each time a function is called, to store its automatic variables. Hence nested or recursive calls to the same function, each successively obtain their own separate frames.

Physically, a function's stack frame is the area between the addresses contained in esp, the stack pointer, and ebp, the frame pointer (base pointer in Intel terminology). Thus, if a function pushes more values onto the stack, it is effectively growing its frame..

This is a very low-level view: the picture as seen from the C/C++ programmer is illustrated elsewhere: • Unixwiz.net Tech Tip: Intel x86 Function-call Conventions - C Programmer's View For the sake of discussion, we're using the terms that the Microsoft Visual C compiler uses to describe these conventions, even though other platforms may use other terms.

8. x86 calling conventions

This article describes the calling conventions used when programming x86 architecture microprocessors.

Calling conventions describe the interface of called code:

1. The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated
2. How parameters are passed (pushed on the stack, placed in registers, or a mix of both)
Which registers the called function must preserve for the caller (also known as: callee-saved registers or non-volatile registers) How the task of preparing the stack for, and restoring after, a function call is divided between the caller and the callee.
9. Win32 API: Calling Convention - 2020

A calling convention is a scheme for how functions receive parameters from their caller and how they return a result. The calling conventions can differ in where parameters and return values are placed (in registers; on the call stack; a mix of both), the order they are placed.

5. Win32 API - MFC
6. Kernel Objects, Handles, and Synchronization.
11. Calling convention

The calling convention states how arguments (parameters) are passed to a function and how the caller receives a return value. Amont others, the convention regulates if those values are passed via CPU registers and/or via the stack and which registers are guaranteed to preserve their values accross function calls.

13. Win32 calling conventions: Usage cases

Last time, I talked about some of the general concepts behind the varying calling conventions in use on Win32 (x86). This posting focuses on the implications and usage cases behind each of the calling conventions, in an effort to provide a better understanding as to when you’ll see them used..

14. What are the different calling conventions in C/C++ and what do each mean?

There are different calling conventions available in C/C++: stdcall, extern, pascal, etc. How many such calling conventions are available, and what do each mean? Are there any links that describe these?.

2. voidtools

very good tool to find any file.

3. Visual Studio 2017: Ending the line-ending wars

I write a lot of software in C# using Visual Studio 2017, and about a month ago, Visual Studio and git started arguing over how the .cs source files were formatted with respect to line endings.

We all know that UNIX uses just a newline (linefeed) to end each line, while DOS traditionally uses CR+LF to end lines, and Visual Studio is supposed to be squarely in the DOS world, but for whatever reason, I started getting these messages:.

4. Create portable, custom editor settings with EditorConfig

You can add an EditorConfig file to your project or codebase to enforce consistent coding styles for everyone that works in the codebase. EditorConfig settings take precedence over global Visual Studio text editor settings. This means that you can tailor each codebase to use text editor settings that are specific to that project. You can still set your own personal editor preferences in the Visual Studio Options dialog box. Those settings apply whenever you're working in a codebase without an .editorconfig file, or when the .editorconfig file doesn't override a particular setting. An example of such a preference is indent style—tabs or spaces.

EditorConfig settings are supported by numerous code editors and IDEs, including Visual Studio. It's a portable component that travels with your code, and can enforce coding styles even outside of Visual Studio.

5. Code style rule options

You can define and maintain consistent code style in your codebase by defining .NET code style rule options in an EditorConfig file. These rules are surfaced by various development IDEs, such as Visual Studio, as you edit your code. For .NET projects, these rules can also be enforced at build time. You can enable or disable individual rules and configure the degree to which you want each rule enforced, via a severity level..

6. How do I use editorconfig in Visual Studio 2019?

I created .editorconfig file at solution level in VS 2019 with following settings:.

7. What is EditorConfig?

EditorConfig helps maintain consistent coding styles for multiple developers working on the same project across various editors and IDEs. The EditorConfig project consists of a file format for defining coding styles and a collection of text editor plugins that enable editors to read the file format and adhere to defined styles. EditorConfig files are easily readable and they work nicely with version control systems..

8. EditorConfig Language Service

Language service for .editorconfig files. EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs..

_MERGE_RDATA_ macro

_MERGE_RDATA_ macro

1. Linker Tools Warning LNK4253

section 'section1' not merged into 'section2'; already merged into 'section3'

The linker detected multiple, conflicting merge requests. The linker will ignore one of the requests.

A /MERGE option or directive is encountered and the from section has already been merged into a different section due to a previous /MERGE option or directive (or due to an implicit merge from the linker).

To resolve LNK4253, remove one of the merge requests.

When targeting x86 machines and Windows CE targets (ARM, MIPS, SH4, and Thumb) with Visual C++, the .CRT section is now read only. If your code depends on the previous behavior (.CRT sections are read/write), you could see unexpected behavior..

2. /MERGE (Combine Sections)

/MERGE:from=to.

Remarks The /MERGE option combines the first section (from) with the second section (to), naming the resulting section to. For example, /merge:.rdata=.text.

If the second section does not exist, LINK renames the section from as to.

The /MERGE option is useful for creating VxDs and overriding the compiler-generated section names.

3. Merge .rdata and .data sections into text section

I have a program where I execute C++ code at run time, like in JIT. The program when run, creates C++ code on the fly, converts to LLVM IR and obj using LLVM. It then loads the text section and runs it. The programs runs fine when there is just one text section. I wanted to know how I can run it when there are .data/.rdata sections. Visual Studio linker has /MERGE when can merge .rdata to .text. How can I implement this - so that I can merge the sections in obj to just one text section?.

8. Art of Anti Detection 4 – Self-Defense

Throughout the Art of Anti Detection series we have mainly looked at methods for bypassing automated security products, but in this part we will focus on several self-defense methods for protecting our foothold on the target machines against actual users. These users may be technically insufficient employees or they may be blue team members in a cyber incident division of a company. Our goal is to stay alive and hide our presence inside the target system without having any privileges. But before getting deeper i advise you to read the previous articles of this series, because these methods will include a lot of shellcoding and API hooking thus requires prior knowledge. Now lets get to it !.

9. Introducing New Packing Method: First Reflective PE Packer Amber

Because of the increasing security standards inside operating systems and rapid improvements on malware detection technologies today’s malware authors takes advantage of the transparency offered by in-memory execution methods. In-memory execution or fileless execution of a PE file can be defined as executing a compiled PE file inside the memory with manually performing the operations that OS loader supposed to do when executing the PE file normally. In-memory execution of a malware facilitates the obfuscation and anti-emulation techniques. Additionally the malware that is using such methods leaves less footprints on the system since it does not have to possess a file inside the hard drive. Combining in-memory execution methods and multi stage infection models allows malware to infect systems with very small sized loader programs; only purpose of a loader is loading and executing the actual malware code via connecting to a remote system. Using small loader codes are hard to detect by security products because of the purpose and the code fragments of loaders are very common among legitimate applications. Malware that are using this approach can still be detected with scanning the memory and inspecting the behaviors of processes but in terms of security products these operation are harder to implement and costly because of the higher resource usage (Ramilli, 2010[1])..

16. Executable compression

Executable compression is any means of compressing an executable file and combining the compressed data with decompression code into a single executable. When this compressed executable is executed, the decompression code recreates the original code from the compressed code before executing it. In most cases this happens transparently so the compressed executable can be used in exactly the same way as the original. Executable compressors are often referred to as "runtime packers", "software packers", "software protectors" (or even "polymorphic packers" and "obfuscating tools")..

Crypters are computer applications which are solely used to bypass the antivirus detection of malwares. Hackers use crypters to hide viruses, Trojans, RATS, keyloggers and other hack tools into a new executable, whose sole purpose is to bypass the detection of the same from antivirus. Crypters are basically dead programs which does not affect the actual functionality of the program, they just spoof the actual program behind their encryption and make antivirus fool. Most antivirus detects viruses on basis of heuristics and normal string based detection. Since we have spoofed the original program, so antivirus stand lame and does not detect it as virus..

Case Study 14: zlib compilation

Case Study 13: zlib compilation

Prelude

1. module unsafe for SAFESEH image C++

zlib.lib got issue.

2. My Research on this error

the cause behind this error message.

This happens when you link an .obj or .lib that contains code created by an earlier version of the compiler. Which of course would be common if you downloaded a binary for opencv_ffmpeg instead of the source. You can turn the linker option off but then you'll still have a CRT version incompatibility that can byte. Rebuild the library from source. – Hans Passant May 15 at 13:01

It can also be caused by, as the error states, modules for which the linker can't find safe exception handlers. Assembly language modules in particular - as discussed in other answers. There is some info about this here. – Nick Westgate Jul 5 '17 at 22:17

4. zlib 1.2.8 always uses Windows 8 - level API #49

DanKonigsbach commented on Sep 4, 2014

As @kreuzerkrieg pointed out, the problem is in the commit 5481269, specifically on line 30. The code is trying to define IOWIN32_USING_WINRT_API if and only if the target is a Metro app, by using the test:

#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP)

However, that will be true for both desktop and Metro applications. To test for only Metro applications, and not desktop applications, the following will work:

#if !WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_DESKTOP)
I would like to submit this as a fix. I'm new to GitHub, so I'll need to learn the process first..

By default, zLib uses C calling conventions (CDECL). Gilles Vollant has helpfully provided an STDCALL version of zLib in the past, but his site only provides version 1.2.5, which dates back to January 2012. zLib is currently on version 1.2.8.

Gilles has contributed his WAPI fixes to the core zLib distribution so that anyone can compile it themselves. To do this, you will need to download:

Source Code and FAQs

13. zlib source code on GitHub

zlib source code on GitHub.

zlib 1.2.11 is a general purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and rfc1952 (gzip format).

All functions of the compression library are documented in the file zlib.h (volunteer to write man pages welcome, contact zlib@gzip.org).

A usage example of the library is given in the file test/example.c which also tests that the library is working correctly. Another example is given in the file test/minigzip.c. The compression library itself is composed of all source files in the root directory.

14. madler/zlib: on GitHub

read this length readme.

To compile all files and run the test program, follow the instructions given at the top of Makefile.in. In short "./configure; make test", and if that goes well, "make install" should work for most flavors of Unix. For Windows, use one of the special makefiles in win32/ or contrib/vstudio/ .

Notes for some targets: - For Windows DLL versions, please see win32/DLL_FAQ.txt

15. zlib - Looking the Gift Code in the Mouth:: A Post on Dr. Dobbs

Free software is like pizza - when it’s good, it’s very good. When it’s bad, it can still be pretty good. This article takes a look at zlib, the free data compression library written by Mark Adler and Jean-loup Gailly. Like the very finest pizza, zlib is exceptional.

In this article I will first give a quick overview of what zlib is, and where it came from. I’ll then discuss the existing interface, and look at the wrapper class I created for my own use. Finally, I’ll talk about how I integrated zlib into a a command line test program and a general purpose file compression OCX. After reading this article you should feel comfortable using zlib for many, if not all, of your data compression needs..

zlib’s interface is confined to just a few simple function calls. The entire state of a given compression or decompression session is encapsulated in a C structure of type z_stream, whose definition is shown in Figure 1.

Using the library to compress or decompress a file or other data object consists of three main steps:

1. Creating a z_stream object.
2. Processing input and output, using the z_stream object to communicate with zlib.
3. Destroying the z_stream object.
16. zlib FAQ

Where can I get a Windows DLL version? The zlib sources can be compiled without change to produce a DLL. See the file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the precompiled DLL are found in the zlib web site at http://zlib.net/ ..

Where's the zlib documentation (man pages, etc.)? It's in zlib.h . Examples of zlib usage are in the files test/example.c and test/minigzip.c, with more in examples/ .

21. zlib Usage Example

We often get questions about how the deflate() and inflate() functions should be used. Users wonder when they should provide more input, when they should use more output, what to do with a Z_BUF_ERROR, how to make sure the process terminates properly, and so on. So for those who have read zlib.h (a few times), and would like further edification, below is an annotated example in C of simple routines to compress and decompress from an input file to an output file using deflate() and inflate() respectively. The annotations are interspersed between lines of the code. So please read between the lines. We hope this helps explain some of the intricacies of zlib..

What follows is how BibleTime can be built on Windows using the free version of Visual Studio Express 2012.

27. libpng

libpng is the official PNG reference library. It supports almost all PNG features, is extensible, and has been extensively tested for over 23 years. The home site for development versions (i.e., may be buggy or subject to change or include experimental features) is https://libpng.sourceforge.io/, and the place to go for questions about the library is the png-mng-implement mailing list.

libpng is available as ANSI C (C89) source code and requires zlib 1.0.4 or later (1.2.5 or later recommended for performance and security reasons). The current public release, libpng 1.6.37, fixes the use-after-free security vulnerability noted below, as well as an ARM NEON memory leak in the palette-to-RGB(A) expansion code (png_do_expand_palette())..

Specific questions on ZLIB_WIN32 macro

29. build in windows with zlib should add ZLIB_WINAPI in MakefileBuild.vc

I'd also be interested as to the "why do we need ZLIB_WINAPI ?",, and what version of ZLIB this applies to? I have been building ZLIB as a dependency of CURL for several years and not yet hit on this need.

/* If building or using zlib with the WINAPI/WINAPIV calling convention,
* define ZLIB_WINAPI.
* Caution: the standard ZLIB1.DLL is NOT compiled using ZLIB_WINAPI.
*/
30 second googling appears to indicate that it changes the expectations on the caller (it turns on __stdcall) which makes me nervous, but no more than that..

31. Static ZLIB (1.2.8) linking on Visual Studio 2012

I can't, for the love of God, to static link the ZLIB libs. I have been struggling for a couple hours now with no success. Well, I have followed this tutorial and successfuly compiled both zlibstat.lib and zlibwapi.lib for 32 bits. After setting up my project to use the ZLIB folder with the libraries (Linker > General > Additional Library Directories) and setting zlibwapi.lib (only) as an dependency (Linker > Input > Additional Dependencies) I got it to work, however, that was a dynamic link (I need to distribute my application with the ZLIB dll). I usually use dynamic linking on Debug and static on Release.

I have tried looking for what the hell is the zlibstat.lib and whats it used for, if not for static linking, assuming the "stat" suffix.

Are there any preprocessor to be added into my project, something like ZLIB_STATIC or something, to use static linking of ZLIB or should I have never removed the ZLIB_WINAPI from the zlibstat project, just like the above link told me to do? Is it impossible to static link ZLIB (then, whats zlibstat.lib for?)?

32. Zlib linker error on vs2010

I have a zlib linker error. Spent several hours to try and solve the problem but nothing so far. Zlib was built using vs2010, win32 release. My project is using the same..

Solution Including the zlib.h in the file like this:

#ifdef WIN32 # define ZLIB_WINAPI #endif #include "zlib.h"
33. Unresolved externals despite linking in zlib.lib

I've been trying to compile an application which utilizes zlib compression in VC++ 2010. I get the

error LNK2019: unresolved external symbol _inflateInit2_ referenced in function
....

ANSWER: If you are using the VS2010 solution provided in contrib/ be aware that it's bugged. The zlibstat project defines ZLIB_WINAPI which according to zlib FAQ is used to switch on the STDCALL convention. Just remove it from the project settings and recompile the lib.

34. Zlibstat.lib link error, VS 2010, zlib 1.2.8

I am trying to use zlibstat.lib generated by building solution in zlib-1.2.8\contrib\vstudio\vc10\zlibvc.sln It generated a zlibstat.lib but when I link it with another project I get the following errors:

error LNK2001: unresolved external symbol _compress2
error LNK2001: unresolved external symbol _uncompress
error LNK2019: unresolved external symbol _compress2 referenced in function...
error LNK2019: unresolved external symbol _crc32 referenced in function .....


ANSWER: For anyone coming across this question: I have just solved this myself minutes ago and I personally think that this is a small error in the 1.2.8 sources. The 1.2.8 release contains a VS2010 project to build the zlibstat.lib and altough one would expect a static library file given the name, the macro ZLIB_WINAPI is defined which produces a dynamically linked lib file.

So without further ado: To compile zlibstat.lib in VS2010: Simply go to the project's proprerties, go to C/C++->Preprocessor and remove the ZLIB_WINAPI macro from the Preprocessor Definitions

35. Compiling and using zlib library and libPng library under Windows

36. Frequently Asked Questions about ZLIB1.DLL

This document describes the design, the rationale, and the usage of the official DLL build of zlib, named ZLIB1.DLL. If you have general questions about zlib, you should see the file "FAQ" found in the zlib distribution, or at the following location: http://www.gzip.org/zlib/zlib_faq.html.

38. vs2010下创建工程调用zlib库compress和uncompress的问题

Due to a project, the zlib library is used under windows. The existing libraries are all release versions. If the project is debugged, it will cause a lot of symbol errors, so I have to recompile the zlib library myself..

上面写错了。首先要在Zlib.h头文件添加上ZLIB_WINAPI的宏定义（只有在vs2010的win32项目时候奥）； 然后再 项目->属性->链接器->输入->忽略特定的默认库，把libcmt.lib，加上就ok了。
