範例

下列程式代碼範例會將 comboInstalledPrinters 已安裝的印表機填入下拉式方塊，並在選取範圍變更時，使用 PrinterName 屬性將印表機設定為列印。 初始化 PopulateInstalledPrintersCombo 表單時會呼叫例程。 此範例會要求 PrintDocument 名為 printDoc 的變數存在，而且有特定的下拉式方塊存在。

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;

        printDoc.PrinterSettings.PrinterName= comboInstalledPrinters.Text;
    }
