How do I use VBA to check if a display within my processbook is open? So say I have 3 displays open, X, Y and Z, and display Z is the active display visible to the viewer. I want to assess if display X is open even though it may be sitting in the background. I'm still a beginner in the VBA world and I feel like this should be relatively simple solution but I can't seem to figure it out. Any help is greatly appreciated!
