Esempio

L'esempio di codice seguente popola la comboInstalledPrinters casella combinata con le stampanti installate e imposta anche la stampante su stampa, usando la PrinterName proprietà, quando la selezione cambia. La PopulateInstalledPrintersCombo routine viene chiamata quando il modulo viene inizializzato. L'esempio richiede che esista una PrintDocument variabile denominata printDoc e che esista la casella combinata specifica.

private:
   void PopulateInstalledPrintersCombo()
   {
      // Add list of installed printers found to the combo box.
      // The pkInstalledPrinters String will be used to provide the display String.
      String^ pkInstalledPrinters;
      for ( int i = 0; i < PrinterSettings::InstalledPrinters->Count; i++ )
      {
         pkInstalledPrinters = PrinterSettings::InstalledPrinters[ i ];
         comboInstalledPrinters->Items->Add( pkInstalledPrinters );
      }
   }

   void comboInstalledPrinters_SelectionChanged( Object^ sender, System::EventArgs^ e )
   {
      // Set the printer to a printer in the combo box when the selection changes.
      if ( comboInstalledPrinters->SelectedIndex != -1 )
      {
         // The combo box's Text property returns the selected item's text, which is the printer name.
         printDoc->PrinterSettings->PrinterName = comboInstalledPrinters->Text;
      }
   }

private void PopulateInstalledPrintersCombo()
{
    // Add list of installed printers found to the combo box.
    // The pkInstalledPrinters string will be used to provide the display string.
    String pkInstalledPrinters;
    for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++){
        pkInstalledPrinters = PrinterSettings.InstalledPrinters[i];
        comboInstalledPrinters.Items.Add(pkInstalledPrinters);
    }
}

private void comboInstalledPrinters_SelectionChanged(object sender, System.EventArgs e)
{

    // Set the printer to a printer in the combo box when the selection changes.

    if (comboInstalledPrinters.SelectedIndex != -1) 
    {
        // The combo box's Text property returns the selected item's text, which is the printer name.
        printDoc.PrinterSettings.PrinterName= comboInstalledPrinters.Text;
    }
}

Private Sub PopulateInstalledPrintersCombo()
    ' Add list of installed printers found to the combo box.
    ' The pkInstalledPrinters string will be used to provide the display string.
    Dim i as Integer
    Dim pkInstalledPrinters As String

    For i = 0 to PrinterSettings.InstalledPrinters.Count - 1
        pkInstalledPrinters = PrinterSettings.InstalledPrinters.Item(i)
        comboInstalledPrinters.Items.Add(pkInstalledPrinters)
    Next
End Sub

Private Sub comboInstalledPrinters_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles comboInstalledPrinters.SelectedIndexChanged
    ' Set the printer to a printer in the combo box when the selection changes.

    If comboInstalledPrinters.SelectedIndex <> -1 Then
        ' The combo box's Text property returns the selected item's text, which is the printer name.
        printDoc.PrinterSettings.PrinterName = comboInstalledPrinters.Text
    End If


End Sub
