How to suppress screen activity of external app?

[qwert]

I'm using Send(keys) to remotely control a Save As operation of an external application. And it works great ... except for the series of dialogs that flash up for a tenth of a second each.

Is there a way to turn off all screen updates associated with an external application?

I've tried setting the transparency of that app's window to zero, but it only works for that one window. The dialogs still appear.

At this point, my only other idea is to place a full-screen splash saying "please stand by" while the operations take place -- but that seems "inelegant".

Thanks in advance for any suggestions.

Just thought I would try one bump on this.

Anyone have an idea?
