Im using this FSUIPC Client DLL for a while now and i have to say: BRILLIANT :)


Yesterday i found your 3.0 BETA Version of the client...


Cause I wanted to send a keypress to Prepar3D, I used the new function:

FSUIPCConnection.SendKeyToFS(Keys.K, SendModifierKeys.Control, Me)

...im writing in vb...


The code works perfectly in FSX, but in Prepar3D simply nothing happens. But there is no error though...


Does anybody have an idea, why it doesnt work in Prepar3D?

Hi Philipp,


I don't have P3D so I can't test anything here.


To receive key presses, FSX or P3D must have focus. When you send keys with FSUIPCConnection.SendKeyToFS, the DLL brings the sim into focus using an FSUIPC control called 'Key focus restore'.


It may be that this doesn't work for P3D. Can you just try this out for me and report back? All you need to do is run this line of code from a button or similar:

FSUIPCConnection.SendControlToFS(FSUIPCControl.Key_focus_restore, 0)

If it's working then your application will lose focus and FSX/P3D will get the focus.


Depending on the results I'll see if there's anything that can be done.
