MFC浏览文件路径

VC /MFC浏览文件路径具体代码如下：

CString strFilePath = _T("");//用来保存文件路径
BROWSEINFO bi;
char Buffer[512];
//初始化入口参数bi开始
bi.hwndOwner = NULL;
bi.pidlRoot = NULL;
bi.pszDisplayName = Buffer;//此参数如为NULL则不能显示对话框
bi.lpszTitle = "选择路径";
bi.ulFlags = BIF_RETURNONLYFSDIRS;
bi.lpfn = NULL;
bi.iImage = 0;
//初始化入口参数bi结束
LPITEMIDLIST pIDList = SHBrowseForFolder(&bi);//调用显示选择对话框
if(pIDList)//选择到路径(即：点了确定按钮)
{
SHGetPathFromIDList(pIDList, Buffer);
//取得文件夹路径到Buffer里
strFilePath = Buffer;//将路径保存在一个CString对象里
}
else//取消选择
return;
