没有PrintDialog无法打印 [英] Cannot print without PrintDialog

问题描述

我正在尝试使用PDF创建器作为默认打印机从WORD文档自动创建PDF文档.但是，我不想每次都使用PrintDialog，我需要通过源代码使其自动(我有成千上万的WORD文档).问题在于，似乎我无法继承PrintDialog附带的所有设置，并且可以
创建一个PDF文件，但它的大小为0kb.它引发所有PrintDocument事件
(BeginPrint，QueryPageSettings，PrintPage，EndPrint)，但最终PDF文档为0kb.

有人遇到过这个问题吗?

这是带有静态字段的示例:

I''m trying to create automatically PDF documents from WORD documents, using a PDF creator as a default printer. However, I don''t want to use the PrintDialog everytime, I need to make it automatic by the source code ( I have thousands of WORD documents). The problem is that it seems I cannot inherit all the settings, coming with the PrintDialog and I can
create a PDF file but it''s 0kb. It raises all the PrintDocument events
(BeginPrint,QueryPageSettings,PrintPage,EndPrint), but finally the PDF document is 0kb.

Does anyone met this issue?

Here is a sample with static fields:

private void DocToPdf()
 {
     PrintDocument pdDoc = new PrintDocument();
     try
     {
         pdDoc.DocumentName = @"C:\Input.doc";
         pdDoc.PrinterSettings.PrintToFile = true;
         pdDoc.PrinterSettings.PrintFileName = @"C:\Output.pdf";
         pdDoc.PrinterSettings.PrinterName = "My_printer";
         pdDoc.DefaultPageSettings = new PageSettings(new PrinterSettings());

         pdDoc.PrintPage += new PrintPageEventHandler(pdDoc_PrintPage);
         pdDoc.BeginPrint += new PrintEventHandler(pdDoc_BeginPrint);
         pdDoc.QueryPageSettings += new QueryPageSettingsEventHandler(pdDoc_QueryPageSettings);
         pdDoc.EndPrint += new PrintEventHandler(pdDoc_EndPrint);

         if (pdDoc.PrinterSettings.IsValid)
             pdDoc.Print();
     }
     catch (Exception ex)
     {
         string msg = ex.Message;
     }
 }

推荐答案

您确定您的PrintPage()方法正确将数据写入输出设备吗?

Are you sure that your PrintPage() method is correctly writing the data to the output device?

理查德，谢谢你的提示.实际上，我使用互操作函数解决了该问题.你的暗示使我意识到我走错了路. :)

Hi Richard, thanks for the hint. Actually I solved the problem using interop functions. Your hint helped me to realize that I''m on the wrong way . :)
