All works great however when the value for one textblock updates, both textblocks flash. I was expecting just one TextBlock to flash. Any ideas? ...
I am developing a small desktop application in VB.NET. It has to be formal like a business application. Will I need to use WPF?

Hi, I have an application with one window. I'd like that window to be replicated/mirrored across two external monitors.

This seems all too complicated, but the other alternative I found was creating a custom user control, which is even more excessive. This is what I've done so far: <Style x:Key="DelButton" Targ...
