Can you post what you have so far?

Just attach the VI (or VI's if you have subvis) to your message (see Attachments below message body box).

I`m sorry.

Have a look at the attached modified code.

The regular keys appear in: keys

The other buttons appear in: VKey

Or the ScanCode.

thanks but I use LABVIEW ver 11 and it`s not compatible with your file.

[Ray.R]

Sorry about that. 

It's in version 2010.

thank you

but if you run LABVIEW and you open calculator for example, you can`t catch any key exept you click on LABVIEW window again.

i attached an image for more detail.

Oh.. I didn't realize you wanted to sniff the keyboard while another application is running.  I seem to recall something about that, but will have to  search for it.
