I have this code which detects for a specific error message:

      Catch loError As Exception
         lcError = loError.Message
         Select Case lcError
            Case "Bad Data"
               lcError = "You didn't encrypt the XML string with a valid key."
         End Select
         Return lcError
      End Try

However, as the Case is doing an exact match, it doesn't find a match when Bad Data is returned as the correct string is Bad Data + 3 characters. I don't want to have to deal with the 3 extra characters nor having the removal procedures I had before. How can I make this Case to be not sensitive about the string? Basically, if it starts with Bad Data, this is all I need.
