threading

research on "SynchronizationContext ";

to use CSemaphore class, we need to include "<"afxmt.h">" header file.

1. CMutex Class

Represents a "mutex" — a synchronization object that allows one thread mutually exclusive access to a resource.

2. CEvent Class

Represents an event, which is a synchronization object that enables one thread to notify another that an event has occurred.

Events are useful when a thread must know when to perform its task. For example, a thread that copies data to a data archive must be notified when new data is available. By using a CEvent object to notify the copy thread when new data is available, the thread can perform its task as soon as possible.

CEvent objects have two types: manual and automatic.

3. CCriticalSection Class

Represents a "critical section" — a synchronization object that allows one thread at a time to access a resource or section of code.

the example is clear. it is good for my file list item retrieval and store it into memory for quick drawing.

4. CSemaphore Class

An object of class CSemaphore represents a "semaphore" — a synchronization object that allows a limited number of threads in one or more processes to access a Maintains a count of the number of threads currently accessing a specified resource.

5. A C# Turing Machine

Every computer is equivalent to a Turing Machine, and conversely any Turing Machine can compute anything any other computer can. Perhaps this is one of the more astonishing facts about them: being a really simple machine, a Turing Machine can theoretically, given enough time and resources, run anything you can run on a computer, any algorithm. A small mechanical Turing Machine, such as the one further described, can totally emulate the computer where you are reading this article right now, all the software, operational system etc down to the functionality of the silicon chips. To be more precise, usually Turing Machines are used as basic computational device to which other systems/machines are compare to, so if we say the former is compatible to a Turing Machine, then we mean it has the power to calculate or execute any computable function.

MFC: Visual Studio Resource Editor Class Wizard doesn't have all control IDs under Member Variables

MFC: Visual Studio Resource Editor Class Wizard doesn't have all control IDs under Member Variables. this post talked about one issue related with my previous note. a control ID is not substantiated. so I can not add any class variable.

1. MFC: Visual Studio Resource Editor Class Wizard doesn't have all control IDs under Member Variables
2. Control variable in add member variable wizard is disabled. Why?
3. Unable to add variable to Edit Control, Error: “object reference not set to an instance of object”

this post confirmed my understanding: need to double click the control to add some default event handler, then add other class memembers.

4. MFC development in vs2017
5. Unable to add variable to Edit Control, Error: “object reference not set to an instance of object”

the following answer confirmed my understanding: it is DDE function to be added first..

Please check whether you have DoDataExchange function added to your dialog class. Once I added this function, I am able to add variable using wizard.

When you use the Windows SDK, you can specify which versions of Windows your code can run on. The preprocessor macros WINVER and _WIN32_WINNT specify the minimum operating system version your code supports. Visual Studio and the Microsoft C++ compiler support targeting Windows 7 SP1 and later. Older toolsets include support for Windows XP SP2, Windows Server 2003 SP1, Vista, and Windows Server 2008. Windows 95, Windows 98, Windows ME, Windows NT, and Windows 2000 are unsupported.

When you upgrade an older project, you may need to update your WINVER or _WIN32_WINNT macros. If they're assigned values for an unsupported version of Windows, you may see compilation errors related to these macros.

27. This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended

Error: catastrophic failure (exception from HRESULT:0x8000FFFF(E_UNEXPECTED))

when I am using Visual Studio 2017 on xps 17 laptop, I am using Class Wizard to add member variable into a MFC SDI demo, I got this error message:

catastrophic failure (exception from HRESULT:0x8000FFFF(E_UNEXPECTED))

I searched internet and I find these links. it gave me some thoughts to fix this error message.

1. Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
2. Cycle Clipboard Ring Exception

the solution is one of them: start Visual Stuio as adminstrator. I will try this way and validate it.

"I am facing exactly the same issue. I have VS 2017 15.5.0 on windows 10."

I had this error come up fixed it buy running visual studio 2017 as administrator

the way I started class wizard is from class view in solution folder. then select the form view class->class wizard->cick tab: add memeber variable. this way will cause this error message to throw out.

my workaroun is to start from resource view->IDD_MYMFC15_FORM class( a class you are interested:). a form is opened. select the edit control I am interested-> right click->select add variable. a new variable will be added into this selected class, as this edit control in this example.
