WebBrowser - changing HTML content after DocumentCompleted event

[Robson Siqueira]

Folks,

I am facing a problem. I am trying to manipulate the HTML data (thru the
Document and DocumentText properties) of the WebBrowser object
(System.Windows .Forms).

The problem is that the application enters in a loop state and my changes
don't apply.

Have somebody faced the same problem? Any solutions?

I am using C# / .Net 2.0.

Re: WebBrowser - changing HTML content after DocumentComplet ed event

Hi.

I've done a lot of code that resuses the IE control. I'm not sure what you
mean by "the application enters in a loop state", though. You mean your code
goes into a tight loop and the app freezes or what? If so, don't do that...
:-)

Can you give me an example of exactly what you're trying to change/do?
Perhaps something I can recreate on my end/write a quick piece of code as an
example for you?

Re: WebBrowser - changing HTML content after DocumentComplet ed event

Actually I want to change the code after it is loaded, which happens after
the DocumentComplet ed Event. The problem is that the application keeps
loading the file - if you change it goes all the way over again - and so on.

Do you have any example in which you manipulate the HTML code AFTER the
document was loaded?

Thanks!

Re: WebBrowser - changing HTML content after DocumentComplet ed event

Sounds like you might be having the same problem I had.

Click on this:
news://msnews.microsoft.com/eeUDRpxc...TNGP02.phx.gbl

If your problem is similar to mine, then to get the DocumentComplet e when it
loads, reference shdocvw (find the COM object DLL in
C:\Windows\Syst em32\shdocvw.dl l and reference it in your .NET app) and cast
your ((System.Window s.Forms.WebBrow ser)webBrowser1 ).ActiveXObject to a
SHDocVw.WebBrow ser variable. Then subscribe to the DocumentComplet e event of
the COM object, rather than the DocumentComplet e event of the Windows Forms
instance.

shdocvw.WebBrow ser _ActiveXBrowser = null;
public shdocvw.WebBrow ser ActiveXBrowser
{
get
{
if (_ActiveXBrowse r == null)
{
_ActiveXBrowser =
(SHDocVw.WebBro wser)myWebBrows er.ActiveXInsta nce;
}
return _ActiveXBrowser ;
}
}

private void InitBrowser()
{
_ActiveXBrowser .DocumentComple te += new
SHDocVw.DWebBro wserEvents2_Doc umentCompleteEv entHandler(Acti veXBrowser_Docu mentComplete);
}


To avoid the re-load loop after changing the document content, set a flag in
your event handler to ignore the event if you just changed something.

Re: WebBrowser - changing HTML content after DocumentComplet ed event

Also if you're dynamicizing the content, try to use the IE-DHTML DOM first,
i.e. myBrowser.Docum ent.Body.InnerH tml = ..., rather than
myBrowser.Docum entText = .... Or, use
((mshtml.HTMLDo cument)myBrowse r.Document.DomD ocument).body.i nnerHTML=...
(with mshtml.dll referenced).
