here you've got an edit control, extended with some interesting properties.
Try it out and enjoy. Let me know if you found some bugs in it. Please forget the last posted, because it wasn't very useful. This one is.
Will be extended further if I have some time
Here's an update.
Now it uses a MouseHover / MouseLeave event to show / display the InfoMessage or errormessage when the mouse hovers over the control. It also has an event ValidateEx, which is a good example of programming events the way Microsoft does.
Sorry, here's the file
its a nice sample. can you upload in VB 2005?
