Manually Writing the HTML in TWebBrowser Pt. 2
- by nomad311
As the name suggests this is a continuation (sort of) of http://stackoverflow.com/questions/2784679/manually-writing-the-html-in-twebbrowser
This time around I'm trying to add some auto-refresh logic to the HTML I get. I have pieced together an approach from several sources (see below). In short, I am trying to locate the title node and add a meta node after it (in the HTML head node). But, I get an access violation.
Here is the source:
iHtmlDoc := IHTMLDocument3(WebBrowser1.Document);
iHtmlEleTitle := IHTMLElement2(iHtmlDoc.getElementsByName('title').item(0, 0));
iHtmlEle := IHTMLElement2(IHTMLDocument2(iHtmlDoc).createElement(Format('<meta http-equiv="refresh" content="%d">', [1])));
iHtmlEleTitle.insertAdjacentElement('afterEnd', IHTMLElement(iHtmlEle));
And A (technically not functionally) different way of doing it ...casting is slightly different here:
IHTMLElement2(IHtmlDocument3(WebBrowser1.Document).getElementsByName('title').item(0, 0)).insertAdjacentElement('afterEnd', IHTMLDocument2(WebBrowser1.Document).createElement(Format('<meta http-equiv="refresh" content="%d">', [VPI_ISSUANCE_AUTO_RELOAD])));
Again all I get from Delphi is a access exception, and I fished through MSDN documentation on it, but now I'm hoping someone out there has gone through the same and has some insight. Any help?
