In my spreadsheet, I prompt the user to enter a code. The code should be 4 characters. The code is then placed into a cell. I know that I can use data validation to make sure the user has only entered 4 characters into the cell. However, I want the VBA code to check for that before it is ever entered into the cell. How can I do so?

Copy a format multiple times
Select a formatted range. Double-click the Format Painter (left side of Home tab). You can paste formatting multiple times. Esc to stop
I'm presuming your using an InputBox to get the code. If so, then this should work OK: -
<pre>
Dim Answer As String

Do
Answer = InputBox("Enter a 4 letter code")
If Len(Answer) <> 4 Then MsgBox "No. 4 letters only"
Loop Until Len(Answer) = 4
</pre>
