I'm running excel 2007 on XP.
Is there a way to stop a macro from running during its execution other than pressing escape? Usually if I think I created an infinate loop or otherwise messed something up I hit escape and it throws an error but the macro stops.
This time (and I've done it before but not this badly), I set up a msgbox for some quick debugging. Turns out it had to loop about 6000 times, which made means I had to "OK" 6000 message boxes, which took several minutes. I didn't save before running (another mistake) so I couldn't open task manager to exit.
Is there another way to stop the execution of a macro in case I goof up like this again?
Use CRTL+BREAK to suspend execution at any point. You will be put into break mode and can press F5 to continue the execution or F8 to execute the code step-by-step in the visual debugger.
Of course this only works when there is no message box open, so if your VBA code constantly opens message boxes for some reason it will become a little tricky to press the keys at the right moment.
You can even edit most of the code while it is running.
Use Debug.Print to print out messages to the Immediate Window in the VBA editor, that's way more convenient than MsgBox.
Use breakpoints or the Stop keyword to automatically halt execution in interesting areas.
You can use Debug.Assert to halt execution conditionally.
CTRL + SCR LK (Scroll Lock) worked for me.
Sometimes, the right set of keys (Pause, Break or ScrLk) are not available on the keyboard (mostly happens with laptop users) and pressing Esc 2, 3 or multiple times doesn't halt the macro too.
I got stuck too and eventually found the solution in accessibility feature of Windows after which I tried all the researched options and 3 of them worked for me in 3 different scenarios.
Step #01: If your keyboard does not have a specific key, please do not worry and open the 'OnScreen Keyboard' from Windows Utilities by pressing Win + U.
Step #02: Now, try any of the below option and of them will definitely work depending on your system architecture i.e. OS and Office version
- Ctrl + Pause
- Ctrl + ScrLk
- Esc + Esc (Press twice consecutively)
You will be put into break mode using the above key combinations as the macro suspends execution immediately finishing the current task. For eg. if it is pulling the data from web then it will halt immediately before execting any next command but after pulling the data, following which one can press F5 or F8 to continue the debugging.
You can stop a macro by pressing ctrl + break but if you don't have the break key you could use this autohotkey (open source) code:
+ESC:: SendInput {CtrlBreak} return
Pressing shift + Escape will be like pressing ctrl + break and thus will stop your macro.

I also like to use MsgBox for debugging, and I've run into this same issue more than once. Now I always add a Cancel button to the popup, and exit the macro if Cancel is pressed. Example code:
If MsgBox("Debug message", vbOKCancel, "Debugging") = vbCancel Then Exit Sub
You can also try pressing the "FN" or function key with the button "Break" or with the button "sys rq" - system request as this - must be pressed together and this stops any running macro
I've found that sometimes whem I open a second Excel window and run a macro on that second window, the execution of the first one stops. I don't know why it doesn't work all the time, but you may try.
ESC and CTRL-BREAK did not work for me just now. But CTRL-ESC worked!? No idea why, but I thought I would throw it out there in case it helps someone else. (I had forgotten i = i + 1 in my loop...)
I forgot to comment out a line with a MsgBox before executing my macro. Meaning I'd have to click OK over a hundred thousand times. The ESC key was just escaping the message box but not stopping the execution of the macro. Holding the ESC key continuously for a few seconds helped me stop the execution of the code.
