SendKeyToFS

[dirk riegler]

Hallo

Ich verwende Microsoft Visual Studio Community 2022 (64-Bit) - Current Version 17.5.4 und C#

Ich programmiere IFly737 Tastaturkombinationen auf mein Arduino Schalterpanel.

Bei SendModifierKeys funktionieren Control und Shift jedoch alles mit Alt nicht.

Wo liegt mein Fehler?

 

MfG Dirk

Hi Dirk,

If you are using MSFS, the ALT key is not supported in FSUIPC7. 

It does work with FSX and P3D. If you are using either of those simulators, please show your code.

Hallo,

Das ist für Prepar3d V5.3.

Mit Tastatur ausgelöst Control Alt 2 / im Log steht  >

Your C# code shows Keys.D1. Did you paste the wrong line? The log shows you sent the 2 key...

   867593 FSUIPC Control Action: Ctrl=1070, Param=4658
   867593 SendKeyToFS(00030032=[alt+ctl+2], KEYDOWN) ctr=0

I'm assuming you are calling 

FSUIPCConnection.SendKeyToFS(Keys.D2, SendModifierKeys.Control | SendModifierKeys.Alt);

You can see from the log (in bold above) that my DLL has passed on the correct key code to FSUIPC.

@John DowsonMight be able to tell you why this key combination is working from the keyboard but not through the IPC interface.

The log shows the keys alt+ctl+2 being sent to the FS (both key presses and releases) and also being received back by FSUIPC. Is this key combination assigned in P3D, or in other software? The key combination is only sent to the FS. And it us never a good idea to use the alt key as a modifier, as this has a special meaning in windows for menu operation, which is why it was removed in FSUIPC7.

Hallo, 

genau ich habe die falsche Zeile Kopiert.

Wenn Alt derartige Probleme macht, dann mache ich die letzten Tasten 

mit Control und Shift.

Danke für die Info.
