How do i use code to determine if combobox is open or not?

do you mean the dropdown?
i don't think there is a way to know that (afaik)

you can set it to dropdown in the gotfocus event

me.comboName.dropdown

and as you tab out or the combo box lost the focus, the dropdown is automatically restored..

Hey cap,

Well, what i really need is something that can test whether the list is expanded or need this.

Here's why I need this.  I have written some drag n' drop code that opens a small popup form when i click on something and then, as long as my left mouse button stays depressed, i can drag the popup to its drop location.  If I release the left button, this doesnt work.

So I want to be able to selecct and item from my combo list and have it open the popup for dragging, but I don;t know how to do this without releasing the left mouse button and using the "AfterUpdate" event of the combo.

If I could somehow emulate the "AfterUpdate" event on the combo with actually releasing the left mouse button that would be ideal.

In other words, can I somehow fire the "AfterUpdate" event without releasing the mouse button?

see if this link helps
