RESOLVED Empty, Null, ??? STRING

[swatty]

Hi all,

I am building classes to add and delete objects in the database.

In my classes i've made a property for each field in the table.

For the text fields i've used strings with the exact size of them.

Now when i want to check on a string if it is empty this won't give me the right answer.

Because my string is declared as String * 3, it is filled with 3 ???

How can I check something was inserted in the property of the string ??
This is how i try to check on it but all evaluations return false.

If IsNull(Me.journal) Or Me.journal = vbNullString Then
      ival = 1
      msg = msg & "No journal given." & vbCrLf
   Else
      dum = Me.journal
      If Len(Trim(dum)) < 1 Then
         ival = 1
         msg = msg & "No journal given." & vbCrLf
      End If
      If IsEmpty(Me.journal) Then
         ival = 1
      End If
      If (Me.journal) = Null Then
         ival = 7
      End If
   End If

Does someone now of another way to check on it, which returns the correct answer?
