EnableFrameTheme() Access Violation

Hi,
I am using VS2005 and Codejock 11.02 version. When I create a ribbonbar I get an access violation when call is made to pRibbonBar->EnableFrameTheme(); function.

Any help would be appreciated.

Further I get ASSERT violations in XTPRibbonBar.cpp at line 273.

CXTPRibbonTheme* CXTPRibbonBar::GetRibbonPaintManager() const
{
    CXTPPaintManager* pPaintManager = GetPaintManager();
    ASSERT(pPaintManager->BaseTheme() == xtpThemeRibbon);

    return (CXTPRibbonTheme*)pPaintManager;
}

Please help me in fixing this issue.

Thanks in advance.

Hi Many thanks for the reply . . .I had set the style here is snapshot from OnCreate ()

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
        return -1;
   
    XTPPaintManager()->SetTheme(xtpThemeRibbon);

    if (!CreateStatusBar())
        return -1;

    if (!InitCommandBars())
        return -1;

//Create ribbon bars
}
