Folks, I have a simple web page with frames. I am trying to automate
internet explorer to display the page and allow access to its frames.
Here is the sample code :
using mshtml;
static void Main(string[] args)
{
SHDocVw.Interne tExplorer explorer = null;
explorer = new InternetExplore r();
object nada = null;
explorer.Naviga te("file://" + "c:\\temp\\ xx" + "/frame.htm", ref nada, ref
nada, ref nada, ref nada);
explorer.Visibl e = true;
IWebBrowser2 browser;
browser = (IWebBrowser2)e xplorer;
IHTMLDocument2 doc = (IHTMLDocument2 )browser.Docume nt;
FramesCollectio n frames = (FramesCollecti on) doc.frames; // <<<======
exception
}
The browser launches and shows the page. Here is the web page:
<html>
<head>
<title>Title of page</title>
</head>
<frameset id="top" rows="25%,15%,1 5%,15%,15%,15%" >
<frame id="a" >
<frame id="b" >
<frame id="c" >
<frame id="d" >
<frame id="e" >
<frame id="f" >
</frameset>
</html>
The frames field of the doc variable when accessed is throwing an invalid
cast exception.
Obviously, I have done something wrong. Can someone advise?
thanks,
bob

Hi Bob,
You can get a reference to your frame window like this:
int frameIndex = 0;
indexObj = i; // item() param must be a reference to an object
mshtml.IHTMLWin dow2 frame = (mshtml.IHTMLWi ndow2)doc.frame s.item(ref
indexObj);
If you need to find a frame by its name, loop through frames and check
the frame.name property until it matches what you're looking for.
Unfortunately the frames collection isn't enumerable, so you'll have to
use a "for" loop and frames.length.
HTH,
Chris
Hi Chris. Thanks for the reply. I found my problem. The application is a
console mode app and I "forgot" to mark the main thread with STAThread
attribute. Once I did that and wait for the doc load event the frames were
accessible with no exception.
Sorry for my late night flub.

I have some code that changes a PDF file in another frame using:

create my own control. How would I go on doing this? (I would like to

Does anyone know how to simulate the right click "Save Target As" using

I find that I can navigate through the LinksCollection on any given page but
