Cancel button while Processing

Hi to All,

I am trying to run a FOR... ENDFOR process and want to have an OLE progressbar and an active CANCEL button. How can I do this? I've tried several times but the click event of my CANCEL button seems not to work while inside the FOR... ENDFOR process... Can you help?

Allan,

In your loop you should put a DOEVENTS command which will allow VFP to check
the event queue for the button click.

Besides David's solution, you can use sys(1270) and mdown().

Just beware that the DOEVENTS will allow any other events to occur
too, such as closing the form or pressing any other button or menu
item.

Jack,

You are right. Making the form modal and adding code to QueryUnload (or
setting Closable = .f.) will deal with those items.
