I want to be able to abort some calculations if the user presses a key or clicks the mouse.

I'd like to be able to do this without the hassle of setting up a 2ndthread.

Any ideas?

Cheers Chris

An idea could be, that in the OnClick of the button, you set a variable to true. Before you start your calculation, set the same variable to False.

In your calculation have the following lines:

[...]
Application.ProcessMessages;
If <Your_VariableName> then exit;
[...]

Thanks, 98113772, that's the sort of answer I was looking for :-)

Didn't know about the process messages command.
