Keyboard input to separate Win. application without pressing key

[Oldi]

How can I run (communicate via keyboard) windows application for programming microcontrollers from LabView? I mean “pressing” Ctrl+P for starting programming with LabView without human action.

I've linked an example program here that contains a subVI which simulates keyboard input. You could use it to simulate key strokes, but you would need to do something like an Alt+Tab in order to change key focus to another window. Honestly, controlling the application this way will be tedious and the unpredictability of window tabbing order could present problems. Does this application have an ActiveX (COM) interface? If so, I would recommend using ActiveX in LabVIEW to control the application.

Kind Regards,

At home, I have program Girder http://www.promixis.com/products.php?section=girder, they don't need to change key focus to send keystroke to any running application.

How about this?

Problem is how to simulate any keystroke in some open Windows application from LabView application

In Virtual key constant there is no Alt key to enter Alt+Tab.

The G toolbox from George Zou has a tool that can do the job. I don't know how it will behave with hot keys that are used by the operating system, though.

Oldi,

In the example I directed you to, the virtual key "MENU" is equivalent to the Alt key.

Thanks

 

With combination of Find Winodows.vi and Set Active Window.vi Demo from G Toolbox

and Emulate Keyboard.vi from copytext.zip I get a working VI, but it doesn't work if target application is in a Taskbar. If Application is only inactive, then everything is OK. Good enough.
