I have a VC++ client that attaches to a COM server via
CreateDispatch(). I then get an object from the COM server via a
function called GetItemDocument(long nItem);

If the document doesn't exist, an exception is thrown, and here is my
problem. I can't catch the exception!

My calling code looks like this:
LPDISPATCH lpDisp = NULL;

try
{
lpDisp = m_project.GetItemDocument(0); // here i exit to
AfxCallWndProc() }
catch(COleException &ex)
{
ex.ReportError()
}

MFC exceptions are thrown by pointer. Make it

try {...}
catch (COleException* ex) {
    ex->ReportError();
    ex->Delete();
}

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
