MSChart CreateControl启动Windows安装程序

Question

我在下面的代码中尝试初始化我创建的DLL中的CMSChart。当它到达myChart-＆gt; CreateControl时，出于某种原因，它正在启动Windows Installer对话框，并无限期地说“准备安装......”。我不再能够使用此DLL，因为弹出此安装对话框并且永不退出。 CreateControl启动Windows安装程序对话框的原因是什么？

CMSChart *myChart = new CMSChart();
if( myChart )
{
    RECT    rect;
    rect.left = rect.top = 0;
    rect.right = rect.bottom = 10;

    //Create the control and makre sure it actually creates the window
    if( !myChart->CreateControl(myChart->GetClsid(), _T("Whatever"), WS_POPUP, rect, CWnd::GetDesktopWindow(), 99) ||
        !myChart->m_hWnd )
    {
        HINSTANCE   dllInst = LoadLibrary( _T("MSCHRT20.OCX") );
        HRESULT     rc = 0;
        if( dllInst )
        {
            typedef HRESULT (*STDAPIFUNC) (void);
            STDAPIFUNC  registerServerEntry = (STDAPIFUNC) GetProcAddress( dllInst, "DllRegisterServer" );
            if( registerServerEntry )
                registerServerEntry();
            FreeLibrary( dllInst );
        }
    }
    delete myChart;
}
