Actuating a left mouse click on another computer

[Sigmanut]

I have a simple single axis serial motion control project. I move x distance and snap a picture and repeat the steps 1000 times. However, the motion control is on one computer and the picture is taken by another. I'd like to be able to force  a left mouse click on the picture machine, from the motion control machine.  This is supposed to be a very quick solution as a predessor to a final solution and getting it accomplished quickly is the task. If anyone has any other suggestions as to accomplishing this, I'd love to see them. (my first post)

Need a bit more information first...

Are you looking for a LabVIEW-based solution? Is LabVIEW running on both of these computers? What is supposed to receive the left mouse click on the picture-taking machine?

Thanks for the quick reply.

More detail on the application. This seems like a science fair approach but I using this approach because I'm famaliar with WinBatch and need to get it done quick....   I'm using LabView (on computer #1) to control the motion and hopefully output a switch to another computer (#2) to simulate a left mouse click.  On computer #2 I have WinBatch, a windows macro routine that will click a button to snap the picture, click another button to save the results to a filename, again to specify file type and once more to save the file. Then go back and be ready for the next picture.

You can certainly use LabVIEW to send a message to another application via a Windows API call - if you search this forum you'll come across several examples that show how to do this. Unfortunately I don't know how to extend that for a remote computer. You could do if it you had a small LabVIEW app running on the remote computer that's simply listening for a message from computer #1. You woudn't need the development environment installed on computer #2 - all you would need is the run-time engine, which is free. The LabVIEW app running on computer #2 would then send the message locally to WinBatch.

Perhaps someone else has a better suggestion?
