You could put
Option Compare Text
at the top of the code module to make ALL text comparisons case
insensitive ("A" = "a"). This setting applies to the entire module.
For a specific comparison, use
If StrComp(C1.Value, C2.Value, vbTextCompare) = 0 Then
' strings match
Else
' string don't match.
End If
The third parameter to StrComp can be vbTextCompare to ignore case,
vbBinaryCompare to use case, to use the database comparison settings,
or omitted. If omitted, the Option Compare Text is present in the
module, case is ignored. If omitted and Option Compare Text is not
present in the module, case matters.
