Exempel

I följande kodexempel fylls kombinationsrutan comboInstalledPrinters med de installerade skrivarna och skrivaren skrivs även ut med hjälp av PrinterName egenskapen när markeringen ändras. Rutinen PopulateInstalledPrintersCombo anropas när formuläret initieras. Exemplet kräver att en PrintDocument variabel med namnet printDoc finns och att den specifika kombinationsrutan finns.
