Need advice on using Combo Box

[qwert]

I have a combo box that uses the drop down feature to select from available choices. But when a new selection is made, nothing happens. I can't find an example of how the change in the contents is detected. Lists have the $LBS_Notify style, but I can't find anything like that for combo boxes. I've looked at the lod3n_launcher for hints, but it uses a Go button (or a carriage return action from the field -- which works, but I don't understand). Is a Go button necessary, or is it possible to set up an automatic "Go Upon Any Change" feature?

Any suggestions will be appreciated.

What you're looking at is changing your GUI over to using OnEvent mode.

Check out the example for GUISetOnEvent in the Helpfile, it'll give you the general idea.

**Edit - You can also read up on it more in the Help File under the Contents tab --> GUI Reference --> GUI OnEvent Mode.

Thank you. That was the missing piece.

Addendum: Here are three key points from the GUICtrlSetOnEvent description:

OnEvent functions are only called when the option GUIOnEventMode is set to 1

When in this mode GUIGetMsg is NOT used at all.

Within the called user function the control identifier can be retrieved with @GUI_CTRLID.
