Activating a Window Without Focus

Question

Hello,
I'm using LabVIEW 8.6, I would like to give an unusual behavior to a subVI window when opened: I'd like the window to be activated without giving focus to it. What I mean, is that I would like the window to be able to catch even on the front panel like keystroke or mouse click without giving focus to this window. I'd like the focus to stay on another window.
A good example of what I want to do is the microsoft visual keyboard installed with Windows: when the visual keyboard in open you can press any button without giving focus to the window. I'd like to reproduce the same behaviour with a labview window.
I don't think it's possible with properties or invoke node, I think there might be something to do with the use of user32.dll. If anyone as already done that, or knows how to do it, it would be great.
Thanks for helping.

Hi,
- Have you tried making the main VI modal? Steps are described in this KB
- To do this programmatically, you will need to use the lvwutil32.dll like here 
I googled your question and I found some good information this MSDN forum, I think it may help you to apply it to your code.
Hopefuly this helps.
