PB 2019 R3 2728

This seems like a dumb question but I cannot get the PrintScreen function to print the screen of a secondary monitor (or third, etc).  It only prints the primary.  What am I missing?

Hi, Chris - 

Since the PrintScreen PowerScript function goes wa-a-a-a-aayyy back to the early versions of PB (when there was no multiple monitor support and PB was supported on multiple platforms), I'm pretty sure it only works for the primary monitor. Sounds like a useful enhancement request!

If you're well-versed using the Windows API, you should be able to develop your own NVO that contains the desired functionality. If you can find an example that uses C++ or C# on the web, the conversion to PowerScript MIGHT not be too difficult. Something to think about.

Regards, John

Thanks again John. I will log a bug for that and look for the Windows API implementation.

Testing on my work computer, the .bmp file is created but the of_ShellRun doesn't wait so the FileDelete deletes the file. Comment out the FileDelete if you have problems.
