Setting the Default Property of ActiveX

I am creating an ActiveX control. How I can set what is the default property of the control?

Anybody knows how do that?

Click Tools --> Procedure Attributes on the menu. Click the advanced button. Select the property in the name combobox. Select (default) as procedure id. Click OK and that's it.

Please be aware that there will be no more default properties in vb.net (vb7).

Thanks, this is just that i need.
