Is it possible to add an event handler for SHDocVw.WebBrowser or use AxSHDocVw.WebBroswer without a form in a Windows service?

[David]

I would like to use a AxSHDocVw.WebBroswer control in a Windows service- is
this possible without creating a form? I added the reference I usually use
to add this object in a Windows Application but only SHDocVw appears under
References in the Solution Explorer.

As an alternative, SHDocVw.WebBrowser may work but I am not sure how to add
an event handler for it- does anyone know how to add a DocCompleted event
for this object?

I wonder why you would want to use a visual control in a service which
doesn't provide a user interface.

* What exactly do you want to archieve?
* Which version of .NET are you using?

David,

Not tested however maybe you can try it by using instead of x.webbrowser
x.InterNetExplorer that normaly opens the standard browser.

I'm writing a service that will connect to a website on a regular basis,
retrieve information, and then update external devices- this works fine as
an application but I would rather not use task scheduler to run it and a
service sounds like the best method for this. I started out using
HttpWebRequest but was not successful logging into the website with it-
axWebBrowser worked nicely.

Which authentication model does the Web site use?

Maybe this code snippet is of use for you:

Otherwise take a look at the 'NetworkCredentials' class.

I would not use the webbrowser control for this purpose. Instead you can
download the file in the background:
