Programmatically select the application active window.

[sfrosty]

I need to programatically change active windows between my LabVIEW application and an external Windows application so that the user's input via keyboard will be directed to the proper application.

Hi,
you can download Windows API Function Utilities (32-bit) for LabVIEW from here
http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3EF4556A4E034080020E74861&p_...
This is very useful set of instruments realizing different Win API functions. You will find there one called Move Window to Top which makes the target window the top window, optionally making it the active window. I think this is what you want.
Besides there are many other functions allowing you to control different properties of windows and others.

Good luck.
