execCommand("Print"，false，IDon'tUnderstandThisArgument) [英] execCommand("Print", false, IDon'tUnderstandThisArgument)

问题描述

我想做的是让它以横向模式打印而不显示对话框.这是我到目前为止的内容:

What I'm trying to do is get this to print in landscape mode without showing the dialog box. This is what I have so far:

((mshtml.IHTMLDocument2)Browser.Document.DomDocument).execCommand("Print", true, 0);

我知道以横向模式打印的指令需要通过第三个参数发送，但是我不知道如何构造第三个参数来执行此操作.谁能为我提供一些帮助，以使最后一个论点实现我的目标?

I know that the instruction to print in landscape mode needs to be sent through the third argument, but I don't know how to construct the third argument to do this. Can anyone give me some help on how to make this last argument accomplish my goal?

推荐答案

添加:该文件来自Microsoft

ADDITIONS: This is from Microsoft http://msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument.defaultpagesettings%28v=vs.71%29.aspx

public void Printing()
{
   try
   {
      streamToPrint = new StreamReader (filePath);
      try
      {
         printFont = new Font("Arial", 10);
         PrintDocument pd = new PrintDocument(); 
         pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
         pd.PrinterSettings.PrinterName = printer;
         // Set the page orientation to landscape.
         pd.DefaultPageSettings.Landscape = true;
         pd.Print();
      } 
      finally
      {
         streamToPrint.Close() ;
      }
   } 
   catch(Exception ex)
   { 
      MessageBox.Show(ex.Message);
   }
}

因此，您可能只需将上面示例中的 pd 替换为文档即可.

So you would probably just replace pd in the example above with your document.

原始答案: 可能集成:

ORIGINAL ANSWER: Possibly integrate:

DefaultPageSettings.Landscape = true;

所以也许是这样的:

((mshtml.IHTMLDocument2)Browser.Document.DomDocument).DefaultPageSettings.Landscape = true;
((mshtml.IHTMLDocument2)Browser.Document.DomDocument).execCommand("Print", true, 0);

由于C#是一个薄弱环节，因此在黑暗中有点刺痛，但是我相信这是我曾经在C#应用程序中做到的方式.

Taking a little bit of a stab in the dark since C# is a weak spot but I believe this is how I once did it from an C# application.
