Validate Input In A Textbox?

May 4, 2012

how 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?
