QuestionAdding Workbook In Excel Pin

MemberSB_CodeForFun6-Dec-11 20:02 
Hi,

I have an Excel Addin which loads with Excel Application. Excel Addin then loads a COM dll on the click of Load button.

The loaded COM dll adds an Excel Workbook.

C#
Excel::WorkbookPtr m_ptrDummyWbk;
Excel::WorkbooksPtr ptr_XLWb = m_myExcelPtr->GetWorkbooks();
m_ptrDummyWbk = ptr_XLWb->Add();
m_ptrDummyWbk->PutIsAddin(VARIANT_TRUE);
m_ptrDummyWbk->PutSaved(0,VARIANT_TRUE);


The loaded COM dll is released on the click of Unload button and m_ptrDummyWbk is closed and released.

m_ptrDummyWbk->PutSaved(0,VARIANT_TRUE);
HRESULT hr = m_ptrDummyWbk->Close(VARIANT_FALSE);
m_ptrDummyWbk = NULL
ptr_XLWb = NULL;


Now if i load the COM dll again by clicking the Load Button the application Crashes while adding the workbook

C#
m_ptrDummyWbk = ptr_XLWb->Add();


The error displayed is:
Quote:
Unhandled exception at 0x2f430f9f in EXCEL.EXE: 0xC0000005: Access violation reading location 0x0b0231b8.


What could be the potential cause of this crash and how to get rid of it?
