3. Properties Komponen Form1 Label1 Button1
Properties Name Text Text
Nilai Latihan 1 Tulisan Proses
4. Double klik pada Button1, kemdian ketik script berikut ini Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label1.Text = "STT" End Sub
5. Jalankan Program dengan menekan tombol “F5” atau melalui Menu [ Debug, Start Debugging ] 6. Simpan project ini pada Direktori / Folder “Nim Anda” Pada saat anda membuat project ini, maka akan muncul beberapa file pada direktori yang kita tentukan, diantaranya adalah :
Sebagai hasil Compile / Build, maka akan terbentuk file “exe” yang terdapat pada folder bin\Release\.. 2
