Updated Feb, 2002. ' Free to use and modify, but as always, at own responsibility..' ' Update - February 12, 2001 ' Complete change of way to store menu item text. Now use a separate function ' for this, GetMenuTxt. Advantages - is cleaner and no more hassle with ' GetMenuItemInfo, which seems to behave differently depending on system. ' Win95/98, different versions of NT 4 and 5 - they all seem to behave ' differently. Think MS has managed to screw up real bad there.. ' ' Files: DrawMenu.exe, DrawMenu.bas, DrawMenu.pbr, DrawMenu.rc and Toolbar.bmp ' The bmp contains some 16x16 bitmaps for the menu items. Drawmenu.zip can be ' downloaded from : http://www.algonet.se/~hagsten/pb/drawmenu.zip ' ' Many thanks to Fred Oxenby, Semen Matusovski, Paul Noble and Paul Squires ' for valuable tips and help with testing.
