when making a component (ocx file) of the combo box, and the wear components of the user control, then I compile it into ocx files. Once finished I include the components of it into the main program. then I do click and drag the combo box to the form, but that happens there is an error message "object variable or with block variable not set", what is causing it.
Meanwhile, when I compile the component made no errors at all
please help to enlighten thank you for your help
