Hello,

our QA reports crashes from several client machines originating in code of XTPPaintManager's DrawTextApi() function. They run XP SP2/SP3.

The callstack of the crash gained from those clients (it's exactly the same by all of them) is this:

user32!GetPrefixCount+0x4c
user32!DT_GetExtentMinusPrefixes+0x3a
user32!DT_DrawStr+0x132
user32!DT_DrawJustifiedLine+0x2d
user32!AddEllipsisAndDrawLine+0x128
user32!DrawTextExWorker+0x1a1
user32!DrawTextExA+0xad
user32!DrawTextA+0x46
ToolkitPro1113vc80!CDC::DrawTextA+0x1e
ToolkitPro1113vc80!DrawTextApi+0x5b
ToolkitPro1113vc80!CXTPPaintManager::DrawControlText3+0x13c
ToolkitPro1113vc80!CXTPPaintManager::DrawControlText2+0x27c
ToolkitPro1113vc80!CXTPPaintManager::DrawControlToolBarParent+0x4a8
ToolkitPro1113vc80!CXTPPaintManager::DrawControl+0x7b

Do you have any idea why does the drawing of a CNemXTPControlButton crash inside User32.DLL?

Thanks, in advance!

Hi,

DrawTextApi just call CDC::DrawText... Is there way to catch parameters passed to DrawText ? Maybe you have some weird text to draw...

Do you suspect there can be some very special character sequences in some non-English languages that GDI can't draw?

We have no special info about which texts can cause such a crash (if any), but on the other side, rest of the computers run the same version OK.
