API实现FileDialog

文件夹对话框

BrowseInfo bi;
memset(&bi, 0, sizeof(BROWSEINFO));
  
bi.hwndOwner;  //HWND 
   lpszTitle; //不是标题栏      
   pidlRoot = SHGetSpecialFolderLocation(null,CSIDL_xx,ItemIDList); 	    
   ulFlags = BIF_ReturnOnlyfsDirs|BrowseIncludeFiles;

   pszDisplayName = TCHAR[]; //返回选中item名，不包括全部路径，基本不用

   lpfn = pfun; //int CALLBACK (*)(hwnd, uiMsg, WPARAM , LPARAM );
   lParam = (LPARAM)xx;//LPARAM    

ItemIDList = SHBrowseForFolder(&bi); //API  DoModal  返回值也不是IDOK
//返回必须由应用程序释放，它是调用IMalloc Interface来申请的，所以也通过这个Interface來释放
LPMALLOC pMalloc; //申请一个 IMalloc Interface
if (SUCCEEDED(SHGetMalloc(&pMalloc)))
{
	pMalloc->Free(pIDList);
	(void)pMalloc->Release();
}

SHGetPathFromIDList(ItemIDList , TCHAR[]);
