I'm using Visual Studio .NET 2003 to develop a COM ATL application in unmanaged Visual C++.

I've created a ATL Dialag and whenever I try to add a variable for a control the wizard thorws the message "Object required".

I've tried the following alternatives:

Right click in the control to call "Add variable" from there: this way the wizard does not thorws the message but the variable is not created.
This post, but it is for VS2005.

Does anyone knows any work-around-around for this problem? Or what the wizard actually does so I can do it manually?
