What do else do I have to do?

I have a function that (SendKeys "ESC") to my app. It works, however the if the main screen loses focus to a msgbox the function stops working. My question is, is there something that I'm doing wrong?

Thanks in advance.....

MsgBox:es are modal so to answer your question No, you cant.

You could create another form/process to sendkeys so that a msgbox will not halt it's instructions.

Since its in your app then couldnt you change the focus to another control quite easily with .SetFocus?

Sendkeys are dependent upon the form/control having input focus.
