Voorbeelden

Gebruik de System.Drawing, System.Drawing.Printingen System.IO naamruimten voor dit voorbeeld.

In het volgende codevoorbeeld worden de standaardpagina-instellingen voor een document ingesteld op marges van 1 inch aan elke zijde.

void Printing()
{
   try
   {
      
      /* This assumes that a variable of type string, named filePath,
              has been set to the path of the file to print. */
      streamToPrint = gcnew StreamReader( filePath );
      try
      {
         printFont = gcnew System::Drawing::Font( "Arial",10 );
         PrintDocument^ pd = gcnew PrintDocument;
         
         /* This assumes that a method, named pd_PrintPage, has been
                   defined. pd_PrintPage handles the PrintPage event. */

Opmerkingen

De Margins klasse wordt gebruikt om de breedte van marges in PageSettings en PrintController. MarginsConverter is de typedescriptor voor deze klasse.

Left, Right, Topen Bottom zijn eigenschappen waarmee de marges worden gedefinieerd. Clone maakt een identieke Margins. Equals bepaalt of een ander object dezelfde dimensies heeft als een Margins.

Zie het overzicht van de System.Drawing.Printing naamruimte voor meer informatie over afdrukken.
