>what we used to do in my ancient workplace is to name each textbox, label and other stuff with an ID instead of a caption (or text value). We then have a table in which each form, when loading, look up for the IDS and put the value in the right place. We did that for english and french, but I admit that when doing it for other alphabet, i'm not too sure how to.. I supposed there is a font which contains all symbol for the language you want to use (I supposed hebrew uses different symbol than english, but I might be wrong too).

When we process 1250/1252 codepages this is not problem
We have experience in Bulgarian, Russian, English , French, German, Spenish, Portugese,...
The problems comes when you try to make 1250/1254 codepages - Cyrillic/Greek or Cyrillic/Hebrew
We exchange all label, wiatwindows, messages, etc with variables add classse for combos, grid, etc which take different data according chosen language and place top, left coordinates of every control on the screen.
Some times application do not need some of features in most of the cases you can avoid top,left coordinates if you keep multilanguage rules in Microsoft FAQ.
