3. Press a button on this form.

Thanks,

do you have control over the web page you wish to open ?
for if you don't your looking at a lot of effort to fill in text boxes as you don't know what they are named in someone else's code

Hi,

No I don't have contol over the web site. However it is static on our intranet in which the names of the controls stay the same,

okay there are a few ways to do this..
the first question is what action will the user use to initiate this

so will the user click a button on your application to execute this ?
and what criteria will be enetered into the textboxes on the page  ?

I suggest using WatiN. I believe it was designed with unit testing in mind, but I've used it to automate IE for some of our internal applications. It is even flexible enough to allow you to search for inputs that don't have names or ids, if you so happen to have such.

There is also Selenium Web Driver which does the same thing. I haven't used it myself, but from what I've heard it sounds just a tad more involved to work with than WatiN is.

You can probably get by just using the WebBrowser control in WinForms. I cannot immediately recall how much control you have over the page in WB, but I know that you can execute Javascript against the page, so maybe that would be good enough.

Actually I wanted to bring up ie as a seperate app. As opposed having in on the web form and would like to keep it all native c# code.

But is JavaScript the best way Then?

Thanks,
Ward

Your request is not terribly complex, but there are some nuances that can cause some headaches.

The *easiest* method is to simply create a web browser in C# (lots of examples on the web - cut/paste).  Or if it doesn't have to be visual, just create a web service that creates a web call to the specified page.

once you are pulling the code into a session you can grab the objects via javascript and fill them and then submit the onclick event.
