[RESOLVED] Abort code execution using a cancel button

[irenicus]

Hi everyone,

I've been trying to find this on google or on this forum but couldn't find it.

I have a long procedure to execute. I would like the user to be able to abort the process by clicking a cancel button. However normally after the execution is started no user input is allowed untill the complete procedure is completed. How do i enable userinput (clicking a cancel button) during execution and have the system abort execution?

Any help (in code or tutorials) is appreciated.

Thanks

You can put DoEvents in that long procedure. This will let the User do something else in the application. But mind you the performance will be slow when you put DoEvents. Declare a boolean variable and set it true on the click of the cancel button. And in your procedure check for that variable, if it is true stop the process.

Some additional information may come in handy:

I called this a procedure but actually it's a long process that included multiple procedures and functions (around 50+). I will try to put DoEvents on the most critical positions in the process to allow for cancelation of the procedure and proper abortion of the process.

I will let you know if it worked.

Thanks, it works very well.
