Stop a process

How can I stop or cancel a process. Let say deleting a group of records in an Access table and I would like to have a CANCEL button on a dialog box for user to stop or cancel this process. Could anyone shows me how you could accomplished this? Thanks.

Try:

Do
DoEvents
Loop

Dim KeepGoing as boolean
KeepGoing  = true

'main process
Do While KeepGoing = true
'do your stuff here
DoEvents
loop

'put this in a button's event:
KeepGoing = false

as long as the KeepGoing variable is true, then the loop continues until finished.

KeepGoing is sometimes known as a "Flag" value.

DoEvents, simply pauses the loop and checks if anythink has happened to the program, like a user clicks a button, or a form is minimised etc...
