Q&A, "Manage BLOB Data Fields," by Fabio Claudio Ferracchiati and Juval Lwy [Visual Studio Magazine, August 2003]


SubClassingApp shows how to implement the Subclassing technique in VB.NET. The code retrieves the WM_ACTIVATE system message closing, the application when it loses the focus.

Note: The example contains a VS.NET 2003 solution you can use to study the code. The VS.NET 2002 tool then is not compatible with it. Just create an empty project and add sample code files to it. The SubClassingApp is a VB.NET WinForms project.
