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?
