Thanks Gerry. Is there a VB function to bring up a custom screen where you can specify the screen number? I see OEM functions that open specific panels like, diags, settings, MDI, etc, but nothing to open a custom panel.
Edit: I may have answered my own question. I see that OEM codes 1-7 are for Mach screens but I also see that the next code used is 100. I'm guessing that OEM codes 1 - 99 are reserved for screens so a button using OEM code 50 would open screen #50. Is this correct?
