示例
下面的代码示例使用 comboInstalledPrinters 已安装的打印机填充组合框，并将打印机设置为在选择更改时使用 PrinterName 属性打印。 在 PopulateInstalledPrintersCombo 初始化窗体时调用 例程。 该示例要求 PrintDocument 存在名为 的 printDoc 变量，并且存在特定的组合框。
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 )
