Re: Visual Studio 2005 C++: Office Automation -> Release version crashes

Hi

I try to automate MS Excel via Visual Studio 2005 without MFC. This works
if
I run the debug version, but crashes if I run the release build.

Here is my code snippet to initialize COM and Excel:

bool CExcelInterface::initializeExcel()
{
 CLSID clsid;
 HRESULT hr = 0;
 bool bOK = true;
 IDispatch* ipDispatch = NULL;
 do {
   // Initialize OLE for this thread...
   hr = CoInitialize(NULL);
   if (FAILED(hr)) {
     bOK = false;
     break;
   }

   // Get CLSID for our server...
   hr = CLSIDFromProgID(L"Excel.Application", &clsid);
   if (FAILED(hr)) {
     bOK = false;
     break;
   }
   // Start server and get IDispatch...
   hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch,
(void**) &m_pDispApplication)
   if (FAILED(hr)) {
     bOK = false;
     break;
   }
 } while (false);
 return bOK;
}

This works, as I said, in the debug build, but not in the release build.
In the release build it crashes when I execute CoCreateInstance.

- What could be wrong?
- An option in my project?

Thanks for the help
