I am trying to write a .NET add-in for ProcBook so that when a display is open, it will fix everything on the screen. I used FitAll in VBA code in a display and it works fine. But when I use FitAll in .NET add-in code, it throws error at run time saying "type submitted as a parameter invalid".
aDisplay.Zoom = "FitAll";
What should I pass in order to zoom to Fit All?
