WebBrowser类 [英] WebBrowser class

问题描述

Hello All，

我正在开发一个免费的Windows Scrabble（法语:)）应用程序

广泛使用WebBrowser类的.NET 2.0进行配置，和

数据浏览。它在我的机器上使用WebBrowser类100％工作，并且在Microsoft.MsHtml组件中使用
。我可以通过事件访问页面上的所有元素

，我可以更改一些部分。一切都是用

XSLT渲染的，并通过msHtml直接更改文档。


但显然，它只适用于我的两台机器:-)


当我部署应用程序时，启用/禁用控件不起作用

当应用程序尝试访问SelectElement时，用户得到了

错误：

无法将类型为''System .__ ComObject''的COM对象强制转换为类类型

''mshtml.HTMLSelectElementClass''。进入CLR并且不支持IProvideClassInfo或没有任何interop程序集的COM组件

注册将包含在__ComObject类型中。这种类型的实例

不能投射到任何其他类;但是它们可以转换为接口，因为底层的COM组件支持接口的

IID的QueryInterface调用。


Microsoft.MsHtml随应用程序一起复制，所有用户都有正确安装

，因为它是唯一不起作用的东西


有没有人知道我要做什么，让它在不需要装载Visual Studio的机器上工作，因为它是唯一的区别我可以

弄清楚我的机器和用户机器吗？


谢谢


Laurent

Hello All,
I''m currently developing a free windows Scrabble (in french :)) application
that uses extensively the WebBrowser class of NET 2.0 for configuration, and
data browsing. It works 100% on my machine, with the WebBrowser Class, and
the Microsoft.MsHtml component. I can access all elements on the pages
through the events, I can change some parts. Everything is rendered with
XSLTs and changing directly the document through the msHtml thing.

But apparently, it works only well on both of my machines :-)

When I deploy the application, Enabling / Disabling controls does not work
and when the application try to access a SelectElement the users got that
error :
Unable to cast COM object of type ''System.__ComObject'' to class type
''mshtml.HTMLSelectElementClass''. COM components that enter the CLR and do
not support IProvideClassInfo or that do not have any interop assembly
registered will be wrapped in the __ComObject type. Instances of this type
cannot be cast to any other class; however they can be cast to interfaces as
long as the underlying COM component supports QueryInterface calls for the
IID of the interface.

The Microsoft.MsHtml is copied with the application and all users have a
correct installation, as it is the only thing that doesn''t work

does anyone knows what I have to do, to make it work on machines that
shouldn''t be loaded with Visual Studio, as it''s the only difference I can
figure out with my machines and users machines ?

Thank you

Laurent

推荐答案

我相信Microsoft.MsHtml是一个COM组件..尝试在安装它时使用
注册它。如果您正在使用VS Packaging ..有一个选项可以在属性窗口中为单个文件执行此操作

。检查属性，

属性名称非常明显..

I believe the Microsoft.MsHtml is a COM component.. Try registering it when
installing it. If you are using VS Packaging.. there is a option to do this
for a single file in the properties windows. Check the properties, the
property name is pretty obvious..

Euh我不这么认为，已经在NET组件中找到了

我的项目的引用，但也许它只是一个包装类，而且它是另一个DLL依赖的
？但不知道哪一个:-)

嗯...对不起，我刚才看到了。 ..如果你正在使用浏览器

对象或MS浏览器控件，那将是它自己的一套Dlls..uhmm让我们看看.. b $ b你能告诉我怎么样你正在构建你的安装项目吗？。，就像一个

包括项目输出到VS.NET安装项目然后构建？

uhmm.. yes sorry, I just saw that myself... If you are using the browser
object or the MS Browser control, that will its own set of Dlls..uhmm lets
see.. Can you tell me how you are building your setup project?., Just like a
including a Project Output into VS.NET setup project and then building?
