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); // .... } I've attached the modified files as well as the bitmap. uploads/20070126_113431_Crash.zip
