Hello Mariam.

I put DoDefault() because they advised to me to do this.

Who is they and what is their rationale?

Combo.InteractiveChange()

Is this actually a line of code in your method? This should cause a syntax error (unless, of course, you have a global variable called combo or your global error handler happen to be ON ERROR *)

I'm thinking it's a bug.

Yes, I agree. It is probably a bug in your code < s >.


Personally, I would code it like this:

In the Valid() of the combo box put this code:

*** First of all, let's rename command1 to something
*** more meaningful and self documenting so we have some
*** clue about what it is doing
This.Parent.cmdDoSomethingSpecial.Rrefresh()

And in the refresh of my command button, I would have code like this:

This.Enabled = ( < The combo box's ControlSource has a specific Value or is not empty or some other condition > )
