Terminating an endless loop
in [Visual Basic]
|
From: NadCixelsyd on 6 Jun 2010 21:50 During development, I have inadvertently written an infinite loop on many occasions. I have to terminate the entire application and insert breaks in various places until I find the loop. This sometimes takes upwards of an hour as I have no idea which subroutine contains the loop. Is there a way to terminate an infinite loop without canceling the entire VB session (and find out at least what subroutine I'm in). Can one limit CPU to (for example) 5 seconds and then break?

[sarcasm on] Well, yeah, if your want the EASY way [sarcasm off] I've been hitting break to no avail. It never occurred to me to hit ctrl-break. Merci beaucoup and a hat-tip for the education.

Merci beaucoup and a hat-tip for the education. Also note that the Stop button does the same, but requires a DoEvents in the loop to process the click event. A key press is specially while in the IDE. -- Dee Earley (dee.earley(a)icode.co.uk) i-Catcher Development Team iCode Systems (Replies direct to my email address will be ignored.

No, the Pause button is the same as ctrl-break. The Stop button is the same as "END" and is generally best avoided. |
