Many thanks for all the input. I did do a search earlier but only came near to it with someone who wanted to convert Twips to Pixels. I have been trying to modify someones design of a basic tab control using frames and code to produce shadows/raised edges, but it obviously needs pixels. I would use the standard tab control, but it defaults to such a wide width with 12 tabs even when the legends on the tabs are 1,2,3 etc. There is a property for the tab heights but not widths. Tried putting the tabs sideways but then it was too high. I didn't try removing the tabs to see if it slimmed down. Always a hassle!, why are these people still using 800x600.
