PRB: MFC ActiveX Document Servers Require Compound File Support

Last reviewed: August 7, 1997
Article ID: Q166769

The information in this article applies to:

The Microsoft Foundation Classes (MFC) included with: - Microsoft Visual C++, 32-bit Editions, versions 4.2, 4.2b, 5.0

SYMPTOMS

When you save an ActiveX Document from an ActiveX Document Container such as Internet Explorer or the Office Binder, an ASSERT fails at line 592 in OLEDOC1.CPP.

CAUSE

The MFC ActiveX Document Server classes require compound file support.

RESOLUTION

Add a call to EnableCompoundFile(TRUE) in the document constructor:

   CScribDoc::CScribDoc()
   {
        // ...
        EnableCompoundFile(TRUE);
   }

MORE INFORMATION

Creating a new ActiveX Document server or regular OLE embedding server in AppWizard selects compound file support by default. The assertion problem occurs if compound file support was deselected when the project was initially created.
