SendKeys and Application Activation (SOLVED)

Hey all,

i have searched high and low for this on th net, but could not find a good solution.
I am trying to send a F5 Key Press to another application from my C# proggy.

I know to that with the

Code:

SendKeys.SendWait("{F5}");

statement.

But how can I activate my other Application? I have seen a AppActivate Statement on the net, but I cant find it anywhere in the Framework.

Any help is appreciated,

Thanks, Stephan
