获取应用程序目录,判断文件是否存在

CHAR szExePath[MAX_PATH];

GetModuleFileName(NULL,szExePath,MAX_PATH);

*(strrchr(szExePath,'//'))='/0';

if (GetFileAttributes(szExePath)==-1)")//判断文件是否存在

{MessageBox("!","");}

另类函数

char  szFilename[_MAX_PATH];

char  szDrive[_MAX_DIR];   

char  szDir[_MAX_DIR]; 

::GetModuleFileName(NULL, szFilename, sizeof(szFilename));

_tsplitpath(szFilename, szDrive, szDir, NULL, NULL);

::wsprintf(szPath, _T("%s%s"), szDrive, szDir);

文件夹路径后加上一个斜杠“//”，如果原来已经有的话就不加，没有的话加上PathAddBackslash()
