VS 2008 - Make A Form That Can Enter A Serial (to Validate The Product)Jan 28, 2010
I am trying to make a form that you can enter a serial (to validate the product) this is my code :
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Dim T1 As String = TextBox1.Text
Dim T2 As String = TextBox2.Text
Dim T3 As String = TextBox3.Text
The problem is when i first open my application and i enter my code it goes red, but when i re-enter the code in textbox 1 it works fine, how can i make it work without re-typing?
