Source:

QueryPageSettingsEventArgs.cs

为 QueryPageSettings 事件提供数据。

public ref class QueryPageSettingsEventArgs : System::Drawing::Printing::PrintEventArgs

public class QueryPageSettingsEventArgs : System.Drawing.Printing.PrintEventArgs

type QueryPageSettingsEventArgs = class
    inherit PrintEventArgs

示例

如果打印机支持，下面的代码示例将打印具有第一页颜色的文档。 该示例假定 PrintDocument 已创建名为 的 printDoc 变量，并 PrintPage 处理 和 QueryPageSettings 事件。

对于此示例， System.Drawing 请使用 和 System.Drawing.Printing 命名空间。

private:
   void MyButtonPrint_OnClick( Object^ sender, System::EventArgs^ e )

      // Set the printer name and ensure it is valid. If not, provide a message to the user.
