I want to allow the user to enter symbols using the keyboard. I'm checking the textbox onkeydown event for the pressed key and then change it to a symbol, for example if I would press 'a' then the textbox would show '☺'. But the problem is that the textbox shows both 'a' and '☺'. Is there a better event to check this, or better way to do this?[code]...

View 15 Replieshow one would go about validating input into a textbox for example:
Lets say the first letter the user enters has to be 'A' and the third letter the user enters has to be any number ranging from 0-9 and the length of their input cannot exceed lets say 10.
This is what I have so far:
If txtOperatorID.TextLength > 10 Then
bErrorOccured = True
sErrorMessage = sErrorMessage & "-No more than 10 chars" & vbCrLf
[Code]....
The coding for the length works(is there a better way to do this)? The coding for the first letter to be A works but then I have no idea how to set validation for any proceeding characters entered. Am i right in thinking I have to find their position somehow in the string if so how?
