Hi

I'm getting occasional crashes in this func, where it's trying to draw an image, and the pointer is not NULL, but points to an object that has been deleted.

E.g/.

               pImage = LoadImage(_T("FRAMEBOTTOMRIGHT"));
               if (pImage)
               {
                    rcSrc = pImage->GetSource(bActive ? 0 : 1, 2);
                    CRect rcBottomRight(rc.right - rcSrc.Width(), rc.bottom - rcSrc.Height(), rc.right, rc.bottom);
                    pImage->DrawImage(pDC, rcBottomRight, rcSrc, CRect(0, 0, 0, 0), 0xFF00FF);
               }

where pImage if you browse it is all 0xfeeefeee members.

how could this be deleted and still returned from LoadImage?

I'm using multiple frames with my app....

Hi,

Do you have frames in multiple threads ?

Hi Oleg

yes, each frame has its own thread, else they don't work for things like updating UI etc.

Hi,

Do you have common PaintManager or each frame's commandbars has its own ?

I don't manually set any paint manager on any frame - so whatever the default is.

Hi,

Then try create individual PaintManager + its Images for separate frame:

pCommandBars->SetTheme(xtpThemeOffice2007);

((CXTPOffice2007Theme*)pCommandBars->GetPaintManager())->SetImages(pImages);

Hi Oleg

Sorry - I misunderstood you. I do already call pCommandBars->SetTheme(xtpThemeRibbon) for each frame.

I don't know where I should get pImages from though. They are all standard CodeJock resources - I don't have any images for the 2 items in the quick access toolbar.

I do have a few icons for the ribbon I set though.

Hi,

The thing that now all PaintManagers share same CXTPOffice2007Image collection.

add variable for frame

CXTPOffice2007Images* m_pImages;

in constrcutor m_pImages = new CXTPOffice2007Images();

in destructor delete m_pImages

ans set for theme:

CXTPOffice2007Theme*)pCommandBars->GetPaintManager())->SetImages(m_pImages);
