文件路径获取目录API

总有这样一个API被人遗忘在角落,

从文件路径获取目录名：

Desc：Removes the trailing file name and backslash from a path, if it has them.

 

Syntax：

BOOL PathRemoveFileSpec( LPTSTR pszPath)

 

HEADR：shlwapi.h

 

 

TCHAR PathStr[MAX_PATH];
GetModuleFileName(NULL, PathStr, MAX_PATH);
PathRemoveFileSpecW(PathStr);
CString str;
str.Format(L"%s\\book.mdb", PathStr);
