Web浏览器控件打印 [英] WebBrowser Control Printing

问题描述

问候，


（.NET 2.0，WinXP Pro / Server 2003，带有最新服务包的IE6）。


我''我们决定利用HTML

文档的布局特性来简化我的打印任务，但当然它会抛出一大堆新问题。 ..


我正在从我的应用程序生成HTML中的多页可打印文档，并且

在WebBrowser控件中显示它。我已经考虑使用一些CSS

命令来控制分页，但到目前为止似乎没有任何东西符合要求。


我需要包含一个自定义页眉/页脚（从另一个HTML文件导入）

在每个打印的页面上。我还需要在每个

页面周围画一个边框。我最接近边界的是将我的所有打印内容

放在HTML表格中，这看起来很难看，因为它并没有关闭

英尺每个页面 - 它只在最后的水平线上绘制

文件。


我尝试从WebBrowser继承并覆盖OnPrint事件，但

这似乎永远不会被称为？我在MSDN网站上找到了一个例子，但

它全部用C ++编写，似乎是围绕MFC设计的。


如何挂起关于HTML的时髦内置格式化功能，但

仍然可以控制打印输出和放大器分页？帮助！


提前致谢，

Alex Clark

Alex，


我建议您查看打印模板：

您好Colin，


这些看起来非常有用，但文章似乎暗示在使用C ++时这只是

。我知道它是很久以前写的（之前是

..NET）但它似乎并不像VB.NET友好的那样:-(

谢谢，

Alex

Alex，


打印模板当然不重要，但它们不需要C ++。我给出的示例代码的

键代码是：


pCmdTarg-> Exec（& CGID_MSHTML，

IDM_PRINT，

OLECMDEXECOPT_PROMPTUSER，

& vTemplatePath，

NULL）;


基本上，是什么你会在.NET中将你的IWebBrowser2对象转换为

IOleCommandTarget并调用Exec方法（如上所述）将路径传递给

你的打印模板（vTemplatePath in上面的例子。）绝大多数

的打印模板代码将用JavaScript编写。


老实说，我认为你最好投资一个报告书写工具

（例如ActiveReports）你带WB的路径不是一个简单的路径。

Greetings,

(.NET 2.0, WinXP Pro/Server 2003, IE6 with latest service packs).

I''ve decided to take advantage of the layout characteristics of HTML
documents to simplify my printing tasks, but of course it''s thrown up a
whole host of new issues...

I''m generating a multi page printable document in HTML from my app, and
displaying it in a WebBrowser control. I''ve looked into using some CSS
commands to control pagination, but nothing seems to fit the bill so far.

I need to include a custom header/footer (imported from another HTML file)
on every page that''s printed. I also need to draw a border around each
page. The closest I can get to the border is putting all my print-content
inside an HTML table, which looks ugly because it doesn''t close off at the
foot of each page - it only draws its final horizontal line at the very end
of the document.

I tried inheriting from WebBrowser and overriding the OnPrint event, but
this never seems to get called? I''ve found an example on the MSDN site, but
it''s all in C++ and seems designed around MFC.

How can I hang on to the snazzy built-in formatting features of HTML, but
still have control over the printed output & pagination? Help!

Thanks in advance,
Alex Clark

Alex,

I suggest you look into Print Templates:

Hi Colin,

These look really useful but the article seems to imply that this is only
possible when using C++. I know it was written a long time ago (before
..NET) but it doesn''t seem as though it could be very VB.NET friendly :-(

Thanks,
Alex

Alex,

Print Templates are certainly non-trivial, but they do not require C++. The
key line of code from the example I gave is:

pCmdTarg->Exec(&CGID_MSHTML,
IDM_PRINT,
OLECMDEXECOPT_PROMPTUSER,
&vTemplatePath,
NULL);

Basically, what you would do in .NET is cast your IWebBrowser2 object to an
IOleCommandTarget and call the Exec method (as above) passing in the path to
your print template (vTemplatePath in the above example.) The vast majority
of the Print Template code will be written in JavaScript.

Honestly, I think you would be better investing in a report writing tool
(e.g. ActiveReports) The path you are headed down with the WB is not an
easy one.
