VC中没有现成的函数来选择一个文件夹，但这是经常会用到的，怎么办？
自动动手，丰衣足食！

使用SHBrowseForFolder，代码如下：

#include <Shlobj.h>
  
int SelFolder(HWND hParent, CString &strFolder)
{
    strFolder.Empty();
 
    LPMALLOC lpMalloc;
 
    if (::SHGetMalloc(&lpMalloc) != NOERROR) return 0;
 
    char szDisplayName[_MAX_PATH];
    char szBuffer[_MAX_PATH];
    BROWSEINFO browseInfo;
    browseInfo.hwndOwner = hParent;
    browseInfo.pidlRoot = NULL; // set root at Desktop
    browseInfo.pszDisplayName = szDisplayName;
    browseInfo.lpszTitle = "Select a folder";
    browseInfo.ulFlags = BIF_RETURNFSANCESTORS|BIF_RETURNONLYFSDIRS;
    browseInfo.lpfn = NULL;
    browseInfo.lParam = 0;
 
    LPITEMIDLIST lpItemIDList;
    if ((lpItemIDList = ::SHBrowseForFolder(&browseInfo)) != NULL)
    {
        // Get the path of the selected folder from the    item ID list.
        if (::SHGetPathFromIDList(lpItemIDList, szBuffer))
        {
            // At this point, szBuffer contains the path the user chose.
            if (szBuffer[0] == '\0') return 0;
 
            // We have a path in szBuffer! Return it.
            strFolder = szBuffer;
            return 1;
        }
        else return 1; // strResult is empty
 
        lpMalloc->Free(lpItemIDList);
        lpMalloc->Release();
    }
   
 return 1;
}
