How to Control Window's Keyboard Using LabVIEW

[jackhsu66]

Hello NI Community,

I am trying to design a program so that LabVIEW can take over my Windows PC keyboard.

For example, if I press a button or toggle a switch on LabVIEW, I want my actual PC computer's keyboard to press down on a specified key such as the letter 'A'.

However, I have no luck in searching if this is even possible. There are only examples of LabVIEW recognizing my keyboard press but I can't let LabVIEW control my keyboard press. I would really appreciate any suggestions on how to start or where to look at. Thanks in advance!

Hi jackhsu,

did you search for "create keypress event"?

You will find results like this…

A keyboard is an input device and there is no motor to move keys on demand like on a player piano. You probably have something else in mind, such as simulate a key press.

What should have key focus? Your LabVIEW app or some third party program?

Hi Jackhsu66,

May be you need to think about a solution to control "virtual keyboard" in windows PC if the 'keyboard button press' event handling doesn't fit for your application
