Hello,
I'm working on an application that uses an AxWebBrowser control. I've had a
couple of problems. I dynamically create the HTML that I load into some of
the pages and others are static pages. Sometimes when I click on a link
that should take be to a dynamic page I get a "Page cannot be found" page
instead. Then I click back and click on the link again and it works fine.
It seems to be a timing issue, but I can't quite figure it out. Basically
my code to create the page dynamically looks like this:
//**********
IHTMLDocument2 HTMLDocument = null;
HTMLDocument = (IHTMLDocument2)webMain.Document;
HTMLDocument.clear();
HTMLDocument.write(h);
HTMLDocument.close();
Thread.Sleep(250);
HookingEvents();
//**********
h is a string that is created in some other functions. HookingEvents loops
through document and creates the events for when someone clicks on a link.
//*********
public void HookingEvents()
{
IHTMLDocument2 doc;
object boxDoc = this.webMain.Document;
doc = (IHTMLDocument2)boxDoc;
if (doc != null )
{
IHTMLElementCollection allElems = doc.all;
if ( allElems == null ) return;
int len = allElems.length;
// DocComplete fires multiple times, check that we have
elements.
if ( len < 1) return;
for ( int i = 0; i< len; i++)
{
object boxe = allElems.item(i,i);
IHTMLElement elem = (IHTMLElement)boxe ;
string tagName = elem.tagName.ToUpper();
if ( tagName == "A" )
{
mshtml.HTMLAnchorEvents2_Event aevent =
(mshtml.HTMLAnchorEvents2_Event)
boxe;
aevent.onclick += new
mshtml.HTMLAnchorEvents2_onclickEventHandler(OnAnchorClick);
}
}
}
}
//*******************
OnAnchorClick calls the code above that writes the document. Does anyone
have any thoughts about this? I'm a complete loss for what to do.
One other issue is that my app seems to use a lot of memory. When I look in
the task manager it will be using 100MB and still growing. It seems like
it's still storing each page in memory as I browse.
I hope this makes sense. Thank you very much for any help, I really
appreciate it.
Thanks,
Nick
