Edit Fields without auto highlighting

3 posts in this topic

I would like to make a multi-line edit control that will not have its text highlighted when tabbed to.

Seems too simple.....

Thanks very much for going to all that trouble. I haven't had the chance to go through it line by

line and follow the logic but I'll get to it soon.

This will be a big help since I have had users of my code accidentally overwriting the contents of the edit

field.
