获取文件夹路径 MFC

CString CMyDlg::GetPath()
{
CString strPath = "";
BROWSEINFO bInfo;
ZeroMemory(&bInfo, sizeof(bInfo));
bInfo.hwndOwner = m_hWnd;
bInfo.lpszTitle = _T("请选择路径: ");
bInfo.ulFlags = BIF_RETURNONLYFSDIRS;

LPITEMIDLIST lpDlist; //用来保存返回信息的IDList
lpDlist = SHBrowseForFolder(&bInfo) ; //显示选择对话框
if(lpDlist != NULL) //用户按了确定按钮
{
TCHAR chPath[255]; //用来存储路径的字符串
SHGetPathFromIDList(lpDlist, chPath);//把项目标识列表转化成字符串
strPath = chPath; //将TCHAR类型的字符串转换为CString类型的字符串
}
return strPath;

}

调用：
CString FilePathName;
FilePathName = GetPath();
m_fileparthedit.SetWindowText(FilePathName);
