At the Unload event, check for the textbox. If it is empty then pop up a message and Cancel=1.

I think you'll be better off using the query unload method. (Form_QueryUnload) as not only can you stop the code from unloading you can also check how it is being closed wether it is being forcably shutdown by windows, by task manager or by client.

so summet like

 
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
    If Len(Text1.Text) < 1 Or Combo1.ListIndex = -1 Then
        MsgBox "Please insert a value.", vbCritical, "Error"
        Cancel = 1
    End If
End Sub
