Problems with Flash in WebBrowser

[Guest]

I am having problems interacting with flash objects (i.e., Adobe Flash Player
9) in web pages when using a System.Windows.Forms.WebBrowser control. The
flash objects always seem to display correctly, but when I click on a link
within the flash object the WebBrowser often fails to navigate to the new
page. If I use IE6 (from outside by app) or an AxSHDocVw.AxWebBrowser
control (within my app) then everything works as expected.

You can try this out by creating an app with the following code:

Public Class Form1
Public Sub New()
InitializeComponent()
Me.Size = New Drawing.Size(600, 600)
Dim wb As New System.Windows.Forms.WebBrowser
wb.Dock = DockStyle.Fill
wb.Url = New System.Uri("http://www.falcon-nw.com/")
Me.Controls.Add(wb)
End Sub
End Class

On the web site that opens I can normally navigate to one of the links
(e.g., “WHAT’S NEWâ€). After that the page usually won’t navigate to any of
the other links.

Note that using the AxWebBrowser control would be acceptable if I could
reproduce several of the methods, properties and events that are exposed by
the WebBrowser, such as DocumentText, ShowPageSetupDialog, and NewWindow
(among others).

Thanks for any help!

Hello Lance,

WebBrowser control have a property named DocumentText so we can get the
HTML document text thorugh it. But for other like ShowPageSetupDialog, and
NewWindow, there is no direct support in WebBrowser control. Anyway, you
may achieve this by invoke commands of the HTMLDOCUMENT:

HOW TO: Invoke the Find, View Source, and Options Dialog Boxes for the
WebBrowser Control from Visual C# .NET

Hope this help,

Sincerely,

Hi Luke,

Thanks for the info. It seems that the best solution would be to figure out
why flash is not working in the System.Windows.Forms.WebBrowser control. Any
ideas or possible fixes?

Thanks again,
Lance

Hi Lance,

When you said "flash is not working in the System.Windows.Forms.WebBrowser
control", do yo mean it generate some exception or it cannot
intercommuicate with your code? Does this happen with other flash
object/page?

This is from my original message. Please let me know if it is unclear in any
way.

Hi Lance,

I perform a similar test with your code, and here is what I found:

1. When the Webbrowser control is just load, if I click the navigator menu
like "About", "Desktops", it will work as expect.
2. When the Webbrowser control is just load, I click the icon like "laptop
system", then it go the sub area of "laptop". But, at this time, the
navigator menus don't work anymore.

It seems the problem is related to the status data in the flash and it mey
be a compatibility issue.

Sincerely,

Luke Zhang
