在窗体上使用Web浏览器控件时出错 [英] Error Using Webbrowser Control on Form
问题描述
我正在尝试在VB.Net项目中的表单上显示一些HTML。
我引用了COM WebBrowser控件，并将其实例放在我的
表格。
但是在Form_Load期间，我收到以下错误：
插入的代码生成器表单中的以下代码行（wbReport
是WebBrowser控件的
名称）
CType（我。 wbReport，System.ComponentModel.ISupportInitialize）。EndInit（）
当表单被加载时，这行代码生成一个
InteropServices.ComException
（未知错误）。
这让我发疯，因为我下载了一个使用
WebBrowser的简单示例
VB.Net，它没有这个错误。
几点：
webbrowser控件托管于一个Tab控件，它位于一个表格上，即
是一个MDI孩子。
Cou这些中的任何一个都是罪魁祸首吗？
如何在VB.Net中的表单上显示HTML？
谢谢！

嗨Selden
It那样做！我有完全相同的情况，它总是这样做我的b $ b我也是。这不是一个致命的错误，所以你的应用程序应该继续。
当你打电话给你时，你也会得到同样的非致命异常
AxWebBrowser1.Navigate （...）
我对你下载的没有这个
问题的样本感兴趣。你可以发布一个链接，因为我想看看它的作用是什么吗？b
不同，然后也许我可以为这两个
我们解决这个小难题。

这是我认为MDI已知问题，看看这个新闻组中的消息
为此。

I''m trying to display some HTML on a form in a VB.Net project.
I''ve referenced the COM WebBrowser control, and put an instance of it on my
form.
But during the Form_Load, I''m getting the following error:
The code generator inserted the following line of code in the form (wbReport
is the
name of the WebBrowser control)
CType(Me.wbReport, System.ComponentModel.ISupportInitialize).EndInit( )
When the form gets loaded, this line of code generates a
InteropServices.ComException
("Unknown Error").
This is driving me crazy, since I downloaded a simple example of using the
WebBrowser in
VB.Net, and it works without this error.
A couple of points:
The webbrowser control is hosted on a Tab control, which is on a form that
is an MDI Child.
Could either of these be the culprit?
How can I display HTML on a form in VB.Net?
Thanks!

Hi Selden
It does that! I have exactly the same scenario and it has always done it to
me too. It is not a fatal error though, so your app should continue.
You will also get the same non-fatal exception when you call
AxWebBrowser1.Navigate(...)
I am interested in the sample you downloaded that does not have this
problem. Can you post a link as I would like to see what it does
differently, and then perhaps I can solve this little conundrum for both of
us.

Hi Selden
That is I think a known problem with MDI, see the messages in this newsgroup
for this.
