I am also having similar problem in our MFC application with activex
control embedded in dialog box. I have built whole application in new
VS.NET 2003 environment and all other controls works fine other than
activex control. Thus application is giving lot f debug assertion
Once things which I realized is that window handle to this activex
control is null and thats where its not able to generate activex
control and throws error message. Can anyone help to troubleshoot.
