Short answer: and were pointing you in the right direction — you read the TextBox text and determine its length. In VB.NET the standard property to inspect is the string length (see String.Length documentation). Which exact API you use depends on whether you target VB.NET or classic VB, but the idea is the same: get the Text property and derive the metric you need.

A few practical points that often matter in real apps: trim leading/trailing whitespace if you want "visible" characters only; remember that multi-line input includes newline characters (CR+LF on Windows) which count toward the length; counting words is different from counting characters (split on whitespace and ignore empty entries); if you need the number of digits or the number of occurrences of a particular substring, a regular-expression match or a simple scan are reliable ways to get that count. Also check for empty/null Text before operating to avoid surprises.

UI tips: update the count from the TextChanged event so the user sees a live total, and consider setting TextBox.MaxLength if you want to enforce a limit. For Unicode caution: .NET string length reports UTF-16 code units, so certain emoji or rare characters can occupy two code units and appear as length 2 even though they look like one glyph.

You need to use the LEN function.
