KB153677 - PRB: Implementing Stock Error Event in Custom OLE Control

SYMPTOMS

Visual Basic generates an error message if the MFC Class Wizard's stock Error event is implemented in a custom OLE Control.

For example, if you go to the OLE Events tab in the MFC Class Wizard and add the stock Error event, you will get the following definition in the control's ODL file:

    dispinterface _DTestEvents
    {
     properties:
     //  Event interface has no properties

     methods:
      // NOTE - ClassWizard will maintain event information here.
      //    Use extreme caution when editing this section.
      //{{AFX_ODL_EVENT(CTestCtrl)

      [id(DISPID_ERROREVENT)] void Error(short Number, BSTR*
       Description, SCODE Scode, BSTR Source, BSTR HelpFile,
       long HelpContext, boolean* CancelDisplay);

       .
       .

      //}}AFX_ODL_EVENT
      };

This will generate the following event stub in Visual Basic:

   Private Sub Test1_Error(Number As Integer, Description As String, _
            Scode As Error, Source As String, HelpFile As String, _
            HelpContext As Long, CancelDisplay As Boolean)

   End Sub
