User 11 Panic

[rohanwaugh]

hi all,

i am using following code in my application..

container.h

TBuf<256> SalesOrderContainer1Buff;

container.cpp

TInt indexDealer=iBillToChoiceList->SelectedIndex();
TPtrC16 selectedDealer = BillToItemArray->operator[](indexDealer);
TBuf<50> myDescDealer = (TBuf<50>&)selectedDealer;
SalesOrderContainer1Buff.Append(myDescDealer);
SalesOrderContainer1Buff.Append('#');


TInt indexProduct = iProductChoiceList->SelectedIndex();
TPtrC16 selectedProduct = ProductItemArray->operator[](indexProduct);
TBuf<50> myDescProduct = (TBuf<50>&)selectedProduct;
SalesOrderContainer1Buff.Append(myDescProduct);
SalesOrderContainer1Buff.Append('#');

And i am getting User 11 panic.What is the reason of this panic??
Thanks.Regards.

User 11:
This panic is raised when any operation that moves or copies data to a 16-bit variant descriptor, causes the length of that descriptor to exceed its maximum length.

It may be caused by any of the copying, appending or formatting member functions and, specifically, by the Insert(), Replace(), Fill(), Fillz() and ZeroTerminate() descriptor member functions. It can also be caused by the SetLength() function.

Regards,
Kavit.

But debuggin your code and finding out the line which causes he panic will save time as well as the the focus area of the pblm..

You may want to learn about descriptors, http://descriptors.blogspot.com/ or something may also be in the Wiki, or at least check http://www.symbian.com/developer/tec...ors.guide.html, especially the diagram at the end of the page.
Things like

TPtrC16 selectedProduct = ProductItemArray->operator[](indexProduct);
TBuf<50> myDescProduct = (TBuf<50>&)selectedProduct;
SalesOrderContainer1Buff.Append(myDescProduct);

Are a bit overcomplicated, you could rather write

TPtrC16 selectedProduct = (*ProductItemArray)[indexProduct];
TBuf<50> myDescProduct = selectedProduct;
SalesOrderContainer1Buff.Append(myDescProduct);
