here are my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a As Double Dim b As Double Dim c As Double a = Val(TextBox1.Text) b = Val(TextBox2.Text) For a = a To b Step 1 For c = 2 To a - 1 Step 1 If a Mod c = 0 Then Exit For End If Next ListBox1.Items.Addİ Next End Sub
