Add LR_CREATEDIBSECTION flag for LoadImage call.


That avoids the crash, but transparency doesn't work.

No problem on W2k SP4, only W2k SP2 here, but others have reported the problem also with W2k SP4 and XP Home.

... You can call CXTPImageManagerIcon::LoadBitmapFromFile that automatically detect if it has Alpha channel/png file.

Hi,
 
Add LR_CREATEDIBSECTION flag for LoadImage call.

I've got several reports that the application crashes after the upgrade to 10.40.

I was able to reproduce the crash and to track it down. It crashes as soon as I add a bitmap (.bmp, not .png) with an alpha channel to the QAT.

It doesn't crash on every PC but I've been able to reproduce it on a clean Win2K SP2 English installation.



In the RibbonSample add a CBitmap m_bitmap; to the CMainFrame class and in LoadIcons add the following lines:

void CMainFrame::LoadIcons ()
{
    CXTPCommandBars* pCommandBars = GetCommandBars();

    HANDLE hBitmap = ::LoadImage (NULL, _T("EditUndo.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE);

    m_bitmap.Attach (hBitmap);

    UINT nId = ID_EDIT_UNDO;

    pCommandBars->GetImageManager()->SetIcons(m_bitmap, &nId, 1, CSize(16,16), xtpImageNormal, TRUE);
   

    //pCommandBars->GetImageManager()->SetIcons(IDR_SMALLICONS);
....
}

I've attached the modified files as well as the bitmap.
