从Windows服务打印HTML文档格式打印对话框 [英] Print html document from Windows Service without print dialog

问题描述

我使用的是Windows服务，我想打印的.html页面时，该服务将启动。我用这code和它的打印好。但打印对话框来，我怎么打印照片，无需打印对话框？

 公共无效printdoc（字符串文件）
{
    流程的PrintJob =新的Process（）;    printjob.StartInfo.FileName =文件;
    printjob.StartInfo.UseShellExecute =真;
    printjob.StartInfo.Verb =打印;
    printjob.StartInfo.CreateNoWindow = TRUE;
    printjob.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;    对PrintJob.start（）;
}
 

有没有任何其他的方式来打印此而不显示打印对话框。

更新：响应<一个href=\"http://stackoverflow.com/questions/419412/print-html-document-from-windows-service-without-print-dialog/419427#419427\">this:

不过，我已经使用这个类，但是当我打电话了

<$p$p><$c$c>axW.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT,SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_PROMPTUSER ，楼盘EM，楼盘EM）;

我的程序越来越块这里的时候，我从窗口服务使用，但它是从Windows应用程序正常工作。

解决方案

首先，这里的code：

 使用的System.Reflection;
使用的System.Threading;
使用SHDOCVW;命名空间HTMLPrinting
{
  公共类HTMLPrinter
  {
    私人布尔documentLoaded;
    私人布尔documentPrinted;    私人无效ie_Do​​cumentComplete（对象pDisp，参考目标URL）
    {
      documentLoaded = TRUE;
    }    私人无效ie_PrintTemplateTeardown（对象pDisp）
    {
      documentPrinted = TRUE;
    }    公共无效打印（串htmlFilename）
    {
      documentLoaded = FALSE;
      documentPrinted = FALSE;      InternetExplorer的IE =新InternetExplorerClass（）;
      ie.DocumentComplete + =新DWebBrowserEvents2_DocumentCompleteEventHandler（ie_Do​​cumentComplete）;
      ie.PrintTemplateTeardown + =新DWebBrowserEvents2_PrintTemplateTeardownEventHandler（ie_PrintTemplateTeardown）;      反对失踪= Missing.Value;      ie.Navigate（htmlFilename，参考失踪，失踪参考，参考失踪，失踪参考）;
      而（documentLoaded＆安培;！＆安培;！ie.QueryStatusWB（OLECMDID.OLECMDID_PRINT）= OLECMDF.OLECMDF_ENABLED）
        Thread.sleep代码（100）;      ie.ExecWB（OLECMDID.OLECMDID_PRINT，OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER，裁判失踪，失踪参考）;
      而（！documentPrinted）
        Thread.sleep代码（100）;      ie.DocumentComplete  -  = ie_Do​​cumentComplete;
      ie.PrintTemplateTeardown  -  = ie_PrintTemplateTeardown;
      ie.Quit（）;
    }
  }
}
 

1. 您可以通过添加到Microsoft Internet控制，添加引用对话框的COM选项卡上找到一个参考访问SHDOCVW命名空间。


2. InternetExplorer对象的更多信息，请 MSDN 找到


3. 的导航（）方法将加载HTML文件。其他参数允许您指定可选参数，如标志和标头。


4. 我们无法打印，直到文件被加载。在这里，我进入一个循环等待直到DocumentComplete事件被调用，在其上标记被设置通知我们导航已完成。注意，每当导航完成的DocumentComplete被称为 - 在成功或失败


5. 一旦documentLoaded标志被设置时，印刷状态通过直到启用打印QueryStatusWB（）查询。


6. 开始打印与ExecWB（）调用。在 OLECMDID_PRINT 命令指定， OLECMDEXECOPT_DONTPROMPTUSER 选项以无需用户交互自动打印一起。一个重要的注意的是，这将打印到默认打印机。要指定一台打印机，你将不得不设置默认打印机（在code，你可以调用<一个href=\"http://www.pinvoke.net/default.aspx/winspool/SetDefaultPrinter.html?diff=y\">SetDefaultPrinter()).这两个最后的参数使可选的输入和输出参数。


7. 我们不想放弃，直到打印完成，所以再次进入一个循环。该PrintTemplateTeardown事件被触发之后，documentPrinted标志被设置。然后，对象可以被清理。

I am using a windows service and i want to print a .html page when the service will start. I am using this code and it's printing well. But a print dialog box come, how do i print without the print dialog box?

public void printdoc(string document)
{
    Process printjob = new Process();

    printjob.StartInfo.FileName = document;
    printjob.StartInfo.UseShellExecute = true;
    printjob.StartInfo.Verb = "print";
    printjob.StartInfo.CreateNoWindow = true;
    printjob.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

    printjob.Start();
}

Have there any other way to print this without showing the print dialog box.

Update: in response to this:

But i have already used this class but when i am calling the

axW.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT,SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_PROMPTUSER , ref em, ref em);

My program getting block here when i am using from window service but it is working fine from windows application.

解决方案

First off, here's the code:

using System.Reflection;
using System.Threading;
using SHDocVw;

namespace HTMLPrinting
{
  public class HTMLPrinter
  {
    private bool documentLoaded;
    private bool documentPrinted;

    private void ie_DocumentComplete(object pDisp, ref object URL)
    {
      documentLoaded = true;
    }

    private void ie_PrintTemplateTeardown(object pDisp)
    {
      documentPrinted = true;
    }

    public void Print(string htmlFilename)
    {
      documentLoaded = false;
      documentPrinted = false;

      InternetExplorer ie = new InternetExplorerClass();
      ie.DocumentComplete += new DWebBrowserEvents2_DocumentCompleteEventHandler(ie_DocumentComplete);
      ie.PrintTemplateTeardown += new DWebBrowserEvents2_PrintTemplateTeardownEventHandler(ie_PrintTemplateTeardown);

      object missing = Missing.Value;

      ie.Navigate(htmlFilename, ref missing, ref missing, ref missing, ref missing);
      while (!documentLoaded && ie.QueryStatusWB(OLECMDID.OLECMDID_PRINT) != OLECMDF.OLECMDF_ENABLED)
        Thread.Sleep(100);

      ie.ExecWB(OLECMDID.OLECMDID_PRINT, OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER, ref missing, ref missing);
      while (!documentPrinted)
        Thread.Sleep(100);

      ie.DocumentComplete -= ie_DocumentComplete;
      ie.PrintTemplateTeardown -= ie_PrintTemplateTeardown;
      ie.Quit();
    }
  }
}

1. You can access the SHDocVw namespace by adding a reference to 'Microsoft Internet Controls', found on the COM tab of the Add Reference dialog.
2. More information on the InternetExplorer object can be found on MSDN.
3. The Navigate() method will load the HTML file. The other parameters allow you to specify optional parameters, such as flags and headers.
4. We can't print until the document is loaded. Here, I enter a loop waiting until the DocumentComplete event is called, upon which a flag is set notifying us that navigation has completed. Note that DocumentComplete is called whenever navigation is finished - upon success or failure.
5. Once the documentLoaded flag is set, the printing status is queried via QueryStatusWB() until printing is enabled.
6. Printing is started with the ExecWB() call. The OLECMDID_PRINT command is specified, along with the option OLECMDEXECOPT_DONTPROMPTUSER to automatically print without user interaction. An important note is that this will print to the default printer. To specify a printer, you will have to set the default printer (in code, you could call SetDefaultPrinter()). The two final parameters allow optional input and output parameters.
7. We don't want to quit until printing is complete, so once again a loop is entered. After the PrintTemplateTeardown event is fired, the documentPrinted flag is set. The objects can then be cleaned up.
