如何使用SHGetFileInfo（）方法获取文件夹的打开图标？

This is what I did:

这就是我做的:

LPMALLOC malloc;
LPITEMIDLIST pidl;
SHFILEINFO FileInfo;
SFGAOF sfGao;

if (SUCCEEDED(SHGetMalloc(&malloc))
{
    if (SUCCEEDED(SHParseDisplayName(strDirPath, NULL, &pidl, SFGAO_FOLDER, &sfGao)))
    {
        SHGetFileInfo((LPCWSTR)(PCHAR(pidl)), 0, &FileInfo, sizeof(FileInfo), SHGFI_PIDL | SHGFI_ICON);
        CDC* pDC = GetWindowDC();
        pDC->DrawIcon(10, 10, FileInfo.hIcon);
        ReleaseDC(pDC);
    }
    malloc->Free(pidl);
}
malloc->Release();
LPMALLOC malloc
