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... ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

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. |
