windows引用MFC函数注意事项

1、在项目属性中修改：在共享 DLL 中使用 MFC

2、winMain定义形式要和MFC入口函数(_tWinMain)一样

如以下程序欲使用MFC的TRACE0函数。

#include <afx.h>#include <stdio.h>#include <tchar.h>#pragma warning( disable : 4996)   //去除_vsntprintf不安全错误int MessageBoxPrint(TCHAR* format, ...){TCHAR buf[1024];va_list pArglist;va_start(pArglist, format);_vsntprintf(buf, 1024, format, pArglist);va_end(pArglist);MessageBox(NULL, buf, L"fight", 0);return 0;}int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd){int x, y;x = GetSystemMetrics(SM_CXSCREEN);y = GetSystemMetrics(SM_CYSCREEN);MessageBoxPrint(L"Screen size %d, height: %d", x, y);TRACE0("\nyou are smart boy\n");return 0;}

程序错误。将：

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)改为：int WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,_In_ LPTSTR lpCmdLine, int nCmdShow)问题解决!!!!
