範例

下列程式代碼範例假設 Button 已在 上建立具名 printButton 和 PrintDocument 具名 pd 的 Form。 請確定 Click 的 事件與 printButton_Click 方法相關聯，且 PrintPage 的 PrintDocument 事件與範例中的 方法相關聯pd_PrintPageButton。 範例 printButton_Click 中的 方法會呼叫 Print 引發 PrintPage 事件的方法，並列印 方法中指定的 pd_PrintPage .bmp 檔案。 若要執行此範例，請將路徑變更為您要列印的點陣圖。

針對此範例， System.Drawing請使用、 System.Drawing.Printing和 System.Windows.Forms 命名空間。

private:
   // Specifies what happens when the user clicks the Button.
   void printButton_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      try
      {
         pd->Print();
      }
      catch ( Exception^ ex ) 
      {
         MessageBox::Show( "An error occurred while printing", ex->ToString() );
      }
   }

   // Specifies what happens when the PrintPage event is raised.
   void pd_PrintPage( Object^ /*sender*/, PrintPageEventArgs^ ev )
   {
      // Draw a picture.
      ev->Graphics->DrawImage( Image::FromFile( "C:\\My Folder\\MyFile.bmp" ),
         ev->Graphics->VisibleClipBounds );

      ev->HasMorePages = false;
   }

// Specifies what happens when the user clicks the Button.
