AutoResize version 2

This code resizes a form and it's controls (and fonts) according to the users resolution.

Inputs
designwidth, designheight, designfontsize For example if you designed your app at 800x600 and Small Fonts then you would set the above variables to 800, 600, 96 (or 120 for Large fonts). Then just sit back and let the code do the rest. THIS CODE ALSO ALLOWS BASIC POSITIONING OF CONTROLS. For example L120 would add 120 pixels onto the left coordinate. T200 would add 200 pixels onto the top coordinate. W150 would add 150 pixels onto the width coordinate. H70 would add 70 pixels onto the height coordinate. To achieve this simply enter the letter followed by the amount in the controls 'Tag' property.

Side Effects
No custom controls are supported at the moment. If you need any help with this then e-mail me at: [email protected]
