I want my application to change size of forms and various controls to accomodate different monitors and different resolutions for the same monitor. I am doing some point plotting, using ScaleMode 7 (Centimeters) for a Picture Box (where I plot points) and ScaleMode 1 (Twips) elsewhere.

Any advice, hints, citations, etcetera would be appreciated.

I am working with VB6. I have Visual Studio & MSDN Library.

First, are above Scale Modes reasonable for my purposes? They seem to work okay, but I have yet to add logic for Display changes.

MSDN shows sample code using Sysinfo1_Displaychanged Event. Example uses Screen.TwipsPerPixelX to decide how to size controls. For my System, TwipsPerPixelX does not change when I change from 640X480 to 1024X768. An experiment suggests that Sysinfo1.WorkAreaWidth changes. Does ScaleMode setting affect these variables?

What affects TwipsPerPixel? How do I check for Display Resolution? How do I detect a Monitor with a different Dot Pitch? Should I worry about Dot Pitch?

Any clues you can give me about Twips, Pixels, Scale Mode, Screen sizes, et cetera would be appreciated.

Thanx
