Simulate keypress by code

[Jayme65]

Hi,

I have an application which is entirely driven by keyboard (no mouse!).
In that application there's a "complex" menu where people browse buttons with...the keyboard.
Until then, browsing the buttons was done with the arrows key. I had nothing to code as, by default, this is properly managed by windows!
The "problem" is now that the users wanted the default keys of all my application to be customized!
One could for instance map the directional keys to 8(up), 5(down), 4(left), 6(right).

The best would be to simulated a keypress when those keys are pressed.
How should I please proceed, for instance, to send a "Arrow Up" key pressed event to the system...when the "8" key is pressed!

Hope that I'm clear enought..and thanks for your help!!!

Use the keydown event, in the method you can use e.ImeProcessedKey.

Lotok,

Thanks very much for your reply!
I've tried to get more info on this "e.ImeProcessedKey" and how to use it...and didn't find a lot of info!
Would you please have some more time to complete your answer a little, giving me the explanation on how to use it to get (for instance) a "Arrow Up" keydown...when the"8" key is pressed!

Thanks very much for your help!

You havr to reference Microsoft.Windows.Forms Assembly in the WPF application.

Then you can do

        If e.Key = Key.NumPad8 Then
            System.Windows.Forms.SendKeys.SendWait("{UP}")
        End If

You can pretty much send any keypress in this manner, except I had some issues with {TAB}
Apologies, I was barking up the wrong tree with e.ImeProcessedKey, I hadn't tested in in VS earlier. You will find this helpful: SendKeys Class (System.Windows.Forms)
