What do you mean exactly?

Generally, you don't check user inputs but you convert it when comparing.

For example:
   if "TEST" = ucase$(trim$(text1.text)) then
      msgbox "Strings are the same!!!"
   else
      msgbox "Strings are different!!!"
   endif

My program is a guessing game.  The  user types in what they think the answer is.

Dim sAnswer as String

sAnswer = UCase(Text1.Text)
If sAnswer = "THE ANSWER" Then
 MsgBox "You've Won a Million Dollars"
End If

You can use exactly what I gave you.

You can also use INSTR to verify if your word is in the user's response like this:
if InStr(1, UCase$(trim$(text1.text)), "Your Answer") > 0 then
   msgbox "Good answer"
endif

I would suggest comparing the text using the StrComp function. Here is how to test its usage:

Create a new project add a textbox and a command button.  Paste this code in:

Private Sub Command1_Click()
    If TextDiff(Text1.Text) <> 0 Then
        MsgBox "You have not entered a matching value!"
    Else
        MsgBox "It's a match!"
    End If
End Sub

Private Function TextDiff(InputText As String) As Integer
   
    TextDiff = StrComp(InputText, "No", vbTextCompare)
   
End Function

I should mention that the "No" in StrComp is the string you are trying to match!
