C++ CreateDialog失败，但为什么GetLastError返回0？

我正在使用为我的项目编写一个编辑器。编辑器是一种内部脚本语言，具有所有基本功能，如剪切、复制、粘贴等。作为功能之一，我还提供搜索功能。当用户按Ctrl+F组合键时，理想情况下应显示以下对话框：

但是由于某种原因，CreateDialog API失败，但是GetLastError返回0。另外请注意，我使用的是Windows通用控件

>创建对话框的代码

HWND CreateFindDialog(HINSTANCE hInstance, HWND hWnd, UINT id)
{
    HWND dlgHwnd = ::CreateDialog(hInstance, MAKEINTRESOURCE(id), hWnd, FindDlgProc);
    if(dlgHwnd == NULL)
    {
        wchar_t buf [100];
        wsprintf (buf, L"Error x%x", GetLastError ());
        MessageBox (0, buf, L"CreateDialog", MB_ICONEXCLAMATION | MB_OK);
    }

    return(dlgHwnd);
}

    return FALSE;

任何建议/想法都会有帮助。谢谢。

系统链接控件需要v6的comctl32，如所述。您正在链接到v5 comctl32，我怀疑这是导致错误的原因。您需要包括。

您是如何初始化comctl32的？您显示的是哪个版本？我这样问是因为需要v6 comctl32。@David Heffernan:请查看我更新的答案。如果有帮助的话，我正在使用WindowsVista和ServicePack1、VisualStudio2008以及最新版本的斯金特拉。谢谢。哪个comctl32版本？你有v6应用程序清单吗？@David Heffernan:对不起，我刚才没有回答你的问题。我的应用程序正在接受comctl版本5.82。我已经用这个小代码片段找到了答案
