GUICtrlSetOnEvent what to put in function

[texan]

I created a script with a simple GUI that only contains some labels and a Cancel button. The Script updates software on a PC and signs-on to an application. I am using the GUIOnEventMode because I want the user to be able to press Cancel at any time to exit. This all works fines.

I pass in a UserID as a command line parameter to the script. But, if the userid is missing I create an GUI Edit control & OK button on the screen to allow the user to enter a UserID and continue. If they don't enter anything I want the script to exit after 15 seconds.

Here is where I get confused. I plan to have a loop to wait the 15 seconds to see if the user enters a Userid and presses OK. How do I know to exit this loop when the OK button is pressed?

I will create a function that is performed when the user presses the OK button. I will enter the function name on my GUICtrlSetOnEvent line. But, I don't really need to do anything in the function. I just need to know the user pressed OK.

Try an Inputbox instead, it might make things a LOT easier for you that way.
