"which occures when you statically link the calendar demo sample with the MFC LIB and the XTreme Toolkit LIB"."

Ingo

 

Sorry, can't reproduce it, what line of code in CXTPCalendarThemePart::RefreshMetrics has problem? Guess its something with resources related.

 

btw. Why you wrote it in SkinFramework forum. May be you somehow modified sample before run?

 

The only thing I have changed is that I have switched the project settings from dynamically linking the MFC dll to statically linking the MFC library. I have used Visual Studio .Net 2003.

 

The exception occures in line 597 of xtpcalendartheme.cpp (int nCount = m_arMembers.GetCount();). When I set a breakpoint on this line, the crash occures the second time when the line is passed at program start.

 

The call stack is:

The exception is:

Unbehandelte Ausnahme bei 0x00938079 in CalendarDemoD.exe: 0xC0000005: Zugriffsverletzung-Leseposition 0x00000058.

 

I hope this will help you to locate the bug.

 

You're right, I should have posted it in the calendar control forum.

 

Kind Regards

Maybe the cause for the exception is how you're using the embedded class CTOHeader and how you cast it to CXTPCalendarThemePart. When the function m_arMembers.GetCount() is called, the instruction pointer doesn't jump into the function, it goes into the nirvana. I have seen a similar bug long time ago when a class, which has been derived from multiple other classes by multiple inheritance, wasn't casted correctly to the appropriate base class. An other possible cause may be a bug in the version 2003 of visual studio .net.

Thanks,  Ingo, I reproduced exactly same error :( Strange that all work with vc6 and vc 2005, I will ask our Calendar developer to find reason ASAP.

 

Thanks.

 

Thank you very much for your fast reply, changing the code to

 

TBase* pBase = this;
pBase->TBase::RefreshMetrics(bRefreshChildren);

as you suggested fixed the bug for me. Will you include it in the next release?

 

You also suggested to install Service Pack 1. This doesn't have an effect, because I had already installed Service Pack 1 when the error occured.

 

One last question: Which Visual Studio version do you use at Codejock for development? Do you think it would be better for me to switch to Visual Studio 2005?

 

Kind Regards

Ingo
