Hi.

I'm currently trying to automate some data retrieval from a website using a
form to select data, later the found data is displayed and can be exported
as a csv file.

I have successfully navigated through the pages so far, but i am stuck with
the page, that selects the export type. I can't get from here. Below is the
HTML. I have tried several ways, but i can't seem to extract the button or
link from the document. You can use this to navigate to the page yourself:

wB1.Navigate(new
System.Uri(@"http://frekvensregistret.itst.dk/Co...amp;FCity=&CuCity=&CuName=&CuAdd="));

Any suggestions on how i can simulate pressing the "fortsæt" (continue)
button on the page and maybe also, how i can save the csv file automatic to
disc

/Finn

In javascript it would be

document.getElementById("_lnkOK").click();

There's likely something similar available via C#

Hi Tim

Not quite.. That would refer to the eventhandler... So that i can't use..

I've tried this:

HtmlElement el =
(HtmlElement)wB1.Document.GetElementById("_lnkOK");
object obj = el.DomElement;
System.Reflection.MethodInfo mi =
obj.GetType().GetMethod("click");
mi.Invoke(obj, new object[0]);

But the el object keeps returning as null, so i figure it can't locate that
element in the document.. But wht i can't figure out..

This worked for me:

private void btnTest_Click(object sender, EventArgs e)
{
var doc = wbTest.Document;
var els = doc.GetElementsByTagName("A");
els[0].InvokeMember("click");
}

Not a "named" link, but that shouldn't make any difference....
