方法一：__targv

控制台程序：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]){    CString strPath = argv[0];}

控制台程序和window程序通用(推荐使用)：

CString str(__targv[0]);

注意: 该方法得到路径可能是相对路径,需要转换后获得绝对路径

方法二：_tpgmptr

CString strPath(_tpgmptr);

该方法，编译时会出现警告：

warning C4996: '_wpgmptr': This function or variable may be unsafe. Consider using _get_wpgmptr instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

可以通过在工程中添加预定义宏 _CRT_SECURE_NO_WARNINGS 方式去除警告，建议写成如下形式：

TCHAR* szPath = NULL;#ifdef UNICODE_get_wpgmptr(&szPath);#else_get_pgmptr(&szPath);#endifCString strPath(szPath);

方法三：GetModuleFileName

CString strPath;DWORD nSize = GetModuleFileName( NULL,strPath.GetBuffer(MAX_PATH),MAX_PATH);strPath.ReleaseBuffer();

其它获得系统常用路径的方法：

1.获得当前路径

DWORD dwSize = GetCurrentDirectory(0,NULL);CString strPath;GetCurrentDirectory(dwSize,strPath.GetBuffer(dwSize));strPath.ReleaseBuffer();

2.获得临时文件夹路径

DWORD dwSize = GetTempPath(0,NULL);CString strPath;dwSize = GetTempPath(dwSize,strPath.GetBuffer(dwSize));strPath.ReleaseBuffer();

3.获得WINDOWS和system32路径

DWORD dwSize;CString strPath;dwSize = GetWindowsDirectory(NULL,0);dwSize = GetWindowsDirectory(strPath.GetBuffer(dwSize),dwSize);strPath.ReleaseBuffer();dwSize = GetSystemDirectory(NULL,0);dwSize = GetSystemDirectory(strPath.GetBuffer(dwSize),dwSize);strPath.ReleaseBuffer();

4.推荐使用Shell库中函数

TCHAR szPath[MAX_PATH];int CSIDL[] = {	CSIDL_WINDOWS,		//WINDOWS目录	CSIDL_FONTS,		//字体目录	CSIDL_SYSTEM,		//SYSTEM32目录	CSIDL_SYSTEMX86,			CSIDL_PROGRAM_FILES,//Program Files目录	CSIDL_PROGRAM_FILESX86,	CSIDL_PROGRAM_FILES_COMMON,	CSIDL_PROFILE,	CSIDL_COMMON_FAVORITES,	CSIDL_FAVORITES,	//用户收藏夹	CSIDL_DESKTOP,		//用户桌面目录	CSIDL_MYDOCUMENTS,	//我的文档目录 = CSIDL_PERSONAL	CSIDL_MYPICTURES,	CSIDL_MYMUSIC,	CSIDL_MYVIDEO,	CSIDL_APPDATA,		//用户AppData\Roaming	CSIDL_COOKIES,	CSIDL_TEMPLATES,	CSIDL_RECENT,	CSIDL_SENDTO,	CSIDL_STARTMENU,	CSIDL_PROGRAMS,	CSIDL_ADMINTOOLS,	CSIDL_STARTUP,	CSIDL_LOCAL_APPDATA,	CSIDL_INTERNET_CACHE,	CSIDL_HISTORY,	CSIDL_CDBURN_AREA,	CSIDL_COMMON_DESKTOPDIRECTORY,	CSIDL_COMMON_DOCUMENTS,	CSIDL_COMMON_PICTURES,	CSIDL_COMMON_MUSIC,	CSIDL_COMMON_VIDEO,	CSIDL_COMMON_APPDATA,	CSIDL_COMMON_STARTMENU,	CSIDL_COMMON_PROGRAMS,	CSIDL_COMMON_ADMINTOOLS,	CSIDL_COMMON_STARTUP,	CSIDL_COMMON_TEMPLATES,};for (int i=0 ; i < _countof(CSIDL); i++) {	if(SUCCEEDED(SHGetFolderPath(NULL, CSIDL[i], NULL, SHGFP_TYPE_CURRENT, szPath))) 		_tprintf(_T("%d, %s\n"), i, szPath);	if(SUCCEEDED(SHGetFolderPath(NULL, CSIDL[i], NULL, SHGFP_TYPE_DEFAULT, szPath))) 		_tprintf(_T("%d, %s\n"), i, szPath);}
