I have battled this problem myself last week and consider myself somewhat of an expert now 😉 I’m 99% sure that not all dlls and static libraries were recompiled with the SP1 version. You need to put #define _BIND_TO_CURRENT_MFC_VERSION 1 #define _BIND_TO_CURRENT_CRT_VERSION 1 into every project you’re using. For every project of a real-world size, … Read more
Edit: As j_random_hacker notes, it is possible to force the user to declare a named object in order to take out a lock. However, even if creation of temporaries was somehow banned for your class, then the user could make a similar mistake: // take out a lock: if (m_multiThreaded) { CSingleLock c(&m_criticalSection, TRUE); } … Read more
According to CodeGuru: CString to std::string: CString cs(“Hello”); std::string s((LPCTSTR)cs); BUT: std::string cannot always construct from a LPCTSTR. i.e. the code will fail for UNICODE builds. As std::string can construct only from LPSTR / LPCSTR, a programmer who uses VC++ 7.x or better can utilize conversion classes such as CT2CA as an intermediary. CString cs … Read more
WaitForInputIdle works, but not the way you assume it does. This is largely, because the documentation is misleading (or at least not as explicit as it should be): Waits until the specified process has finished processing its initial input and is waiting for user input with no input pending, or until the time-out interval has … Read more
I don’t like these suggestions of using win32gui because you can’t easily install that via pip. So here’s my solution: First, install pywinauto via pip. If you’re on Python 2.7.9 or a newer version on the 2 branch, or Python 3.4.0 or a newer version from the 3 branch, pip is already installed. For everyone … Read more
+1 Good question! tl;dr: Learn Win32 – in that order. By far the most important prerequisite to MFC is a solid understanding of the Windows API (also sometimes referred to as the Win32 API). You will also need to be familiar with a few key concepts of C++ and get intimate with the tools. My … Read more
The first example is using the System font (SYSTEM_FONT), as retrieved with the GetStockObject function, which is a bitmap font that has not been used since the days of Windows 3. More information is available on Raymond Chen’s blog, and Michael Kaplan’s blog. The second example is using the “MS Shell Dlg” font, just like … Read more
This link must give you some clue. Purpose of stdafx.h The lines defined before the #include “stdafx.h” are ignored by the compiler. So if you want to actually include those files then you need to include them after the #include “stdafx.h”. Hope it is clear.
To answer the first part of your question: LPCSTR is a pointer to a const string (LP means Long Pointer) LPCTSTR is a pointer to a const TCHAR string, (TCHAR being either a wide char or char depending on whether UNICODE is defined in your project) LPTSTR is a pointer to a (non-const) TCHAR string … Read more
In the RC resource file if the dialog has this style similar to this it will be fixed size: IDD_DIALOG_DIALOG DIALOGEX 0, 0, 320, 201 STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU If the dialog has this style it will be sizeable: IDD_DIALOG_DIALOG DIALOGEX 0, 0, 320, 201 STYLE WS_POPUP | WS_VISIBLE | WS_CAPTION … Read more
