Win32 API编程：WinMain没法重载函数或_tWinMain没法重载

#include "windows.h" #include "tchar.h"   int APIENTRY _tWinMain(      HINSTANCE hInstance,      HINSTANCE hPrevInstance,      LPTSTR lpCmdLine,      int nCmdShow      ) {      MessageBox(NULL, TEXT( "Hello,World!" ), TEXT( "haha" ), MB_OK);      return 0; }

1	当采用_tWinMain做为入口函数时，第三个参数类型应定义为 LPTSTR ，表示 WCHAR *型

1 2 3 4 5 6 7 8 9 10 11 12

#include "windows.h" #include "tchar.h"   int APIENTRY WinMain(      HINSTANCE hInstance,      HINSTANCE hPrevInstance,      LPSTR lpCmdLine,      int nCmdShow      ) {      MessageBox(NULL, TEXT( "Hello,World!" ), TEXT( "haha" ), MB_OK);      return 0; }

　当采用WinMain做为入口函数时，第三个参数类型应定义为LPSTR，表示CHAR *型

 

不然出现“WinMain没法重载函数”或_tWinMain没法重载函数“”
