Does LabView have a function similar to 'SendInput()' from C++?

[RogelioRE]

I'm trying to incorporate a string or strings  to the keyboard input stream to enter some data to an application already running (I can not transfer any data to this application since I only have the  .exe file).

As far as I know, there is a function in C++,  SendInput(), that can do this.

Is there any similar function in LabView?

Thx a lot.

That's a Windows API function, so in order to call it from LabVIEW you need to use the Call Library Function Node function under Connectivity -> Libraries & Executables. Search these forums for "SendInput", as this has come up before.

Thx for the info, I'll into that and I guess this can be completed soon. 

Thx again.

Hi Folks,

      I saw this post when it was new and, since then, have been fighting to get SendInput.to work - finally finding the solution on the LAVA forum.  It didn't seem easy to find an example of SendInput or keybd_event, here, so for future NI-LabVIEW forum users, here's an example that shows 3 ways to inject keystrokes - including a very simple .NET method "Windows.System.Forms.SendKeys.SendWait".

Cheers

Hi, tbd!

Good example, but it won't work in LabVIEW 64-bit. To get it working you will need to alter the code according to these recommendations.
