#if _MSC_VER > 1000: why?

#if _MSC_VER > 1000: why?

The predefined macro _MSC_VER indicates the major and minor version numbers of the Visual C++ compiler. The macro's value is an integer literal in which the last two digits indicate the minor version number and the preceding digits indicate the major version number.

I got another error when I compiled a legacy project:

Error C1189 #error: MFC does not support WINVER less than 0x0501. Please change the definition of WINVER in your project properties or precompiled header. MsgMapdemo c:\program files (x86)\microsoft visual studio\2017\enterprise\vc\tools\msvc\14.16.27023\atlmfc\include\afxv_w32.h 40

You need to write:

::HtmlHelp(m_pMainWnd->m_hWnd, m_pszHelpFilePath, HH_HELP_CONTEXT, dwData);

to get the global HtmlHelp() rather than CWinApp::HtmlHelp().
