  2. Data danVariabel

  3. Penggunaan Data danVariabel • Informasi yang disimpanataudiolaholehkomputerdisebut DATA.

  4. Type Data VB • Stringadalah type data untukteks (huruf, angkadantandabaca). • Integeradalah type data untukangkabulat. • Single adalah type data untukangkapecahan • Currency adalah type data untukangkamatauang. • Dateadalah type data untuktanggaldan jam. • Booleanadalah type data yang bernilai TRUE atau FALSE.

  5. Variable • Data yang disimpandidalam memory komputermembutuhkansebuahwadah. • Wadahinilah yang disebutdenganVARIABEL. • Setiapvariabeluntukmenyimpan data dengan type tertentu • Membutuhkanalokasijumlah memory (byte) yang berbeda.

  6. Penulisandeklarasivariabel Dim <nama_variabel> As <type_data> • Contoh : Dim nama_user As String

  7. AturanPenamaanVariabel : • Harusdiawalidenganhuruf. • Tidakbolehmenggunakanspasi. Spasibisadigantidengankarakter underscore (_). • Tidakbolehmenggunakankarakter-karakterkhusus (seperti : +, -, *, /, <, >, dll). • Tidakbolehmenggunakankata-katakunci yang sudahdikenaloleh Visual Basic 6 (seperti : dim, as, string, integer, dll).

  8. Contoh: program variable • GunakankomponenCommandButtondan Label

  9. Pengaturan property setiap object

  10. Dim test2 As Integer Private Sub Command1_Click() Dim test1 As String test1 = "nusantara" Label1.Caption = test1 Label2.Caption = test2 Label3.Caption = test3 End Sub Private Sub Command2_Click() test2 = 10 Label1.Caption = test1 Label2.Caption = test2 Label3.Caption = test3 End Sub • Code Editor ketikkankode program Private Sub Command3_Click() Const test3 As Single = 90.55 Label1.Caption = test1 Label2.Caption = test2 Label3.Caption = test3 End

  11. Operator

  12. Pengertian Operator • Operator merupakansimbol yang digunakanuntukmelakukan suatu operasi terhadap nilai data

  13. Tigajenis operator • Operator Aritmatika • Operator Perbandingan • Operator Logika

  14. Operator Aritmatika

  15. Operator Perbandingan

  16. Operator Logika

  17. Contoh Program : Operator • UI Operator

  18. UI Operator

  19. Pengaturan property setiap object

  20. Code Editor kode program(1) Dim var1 As Single, var2 As Single,hasilAs Single Private Sub Option1_Click() • var1 = Text1.Text • var2 = Text2.Text • hasil = var1 + var2 • Label3.Caption = hasil End Sub Private Sub Option2_Click() • var1 = Text1.Text • var2 = Text2.Text • hasil = var1 -var2 • Label3.Caption = hasil • End Sub

  21. Code Editor kode program(2) Private Sub Option3_Click() var1 = Text1.Text var2 = Text2.Text hasil = var1 * var2 Label3.Caption = hasil End Sub Private Sub Option4_Click() var1 = Text1.Text var2 = Text2.Text hasil = var1 / var2 Label3.Caption = hasil End Sub

  22. Code Editor kode program(3) Private Sub Option5_Click() var1 = Text1.Text var2 = Text2.Text hasil = var1 & var2 Label3.Caption = hasil End Sub Private Sub Option6_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 > var2) Label3.Caption = hasil Label3.Caption = Format(hasil, "True/False") End Sub

  23. Code Editor kode program(4) Private Sub Option7_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 < var2) Label3.Caption = Format(hasil, "True/False") End Sub Private Sub Option8_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 = var2) Label3.Caption = Format(hasil, "True/False") End Sub

  24. Code Editor kode program(5) Private Sub Option9_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 <> var2) Label3.Caption = Format(hasil, "True/False") End Sub Private Sub Option10_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 >= var2) Label3.Caption = Format(hasil, "True/False") End Sub

  25. Code Editor kode program(6) Private Sub Option11_Click() var1 = Text1.Text var2 = Text2.Text hasil = (var1 <= var2) Label3.Caption = Format(hasil, "True/False") End Sub Private Sub Option12_Click() var1 = IIf(Text1.Text = "True", -1, 0) hasil = Not (var1) Label3.Caption = Format(hasil, "True/False") End Sub

  26. Code Editor kode program(7) Private Sub Option13_Click() var1 = IIf(Text1.Text = "True", -1, 0) var2 = IIf(Text2.Text = "True", -1, 0) hasil = (var1 Or var2) Label3.Caption = Format(hasil, "True/False") End Sub Private Sub Option14_Click() var1 = IIf(Text1.Text = "True", -1, 0) var2 = IIf(Text2.Text = "True", -1, 0) hasil = (var1 And var2) Label3.Caption = Format(hasil, "True/False") End Sub
