Type Mismatch

I've declared a global variable:

Public strBarCode As String

On opening a certain form I want it to check to see if that string is populated.

Private Sub Form_Open(Cancel As Integer)
    If strBarCode Is Not Null Then
        Me![txtBarCode].Value = strBarCode
    End If
End Sub


But on the bold line above I'm getting a Type Mismatch Compile Error.

The global variable is working correctly because if I check and hover over strBarCode it returns the value I'm expecting 2222. I made it a string as some Bar Codes sometimes have letters in.

What have I done wrong? Help appreciated and thanks in advance.

Private Sub Form_Open(Cancel As Integer)
    If IsNull(strBarCode)= false Then
        Me![txtBarCode].Value = strBarCode
    End If
End Sub

or
Private Sub Form_Open(Cancel As Integer)
    If not IsNull(strBarCode) Then
        Me![txtBarCode].Value = strBarCode
    End If
End Sub
