No way... If you are talking about process in the client side, it cant detect it from the browser.. As browser only deals with htmls(Request / Response). It dont have access to anything, but just to display some Data and Ui elements.

If you are looking for server side processes, it is very easier to deal with this. Just use
System.Diagnostics.Process[] processlist = System.Diagnostics.Process.GetProcesses()

But I dont think your motive is fulfilled using this as no one opens internet explorer to work with their own site in the server.

Anyway.. Be specific on what you require always. And post in right section.

Cheers.

I doubt this. ASP.NET process runs on a restricted account and will not have full trust. GetProcesses() method is likely to fail if invoked from ASP.NET application.

Yes.. But I guess giving proper rights to the user (or impersonating) to run the aspnet worker process as an administrator will surely solves the issue ..

But seriously... this is not generally what we do often... but it is possible I guess.

Then You better ask third pary tool developing team..!

As you are using the 3rd party tool first check tht it is supported for such type..!

BTW You didnt mention the 3 rd party vendor name so tht if any one uses the 3rd party tool before they can help You..!

Re: Querystring issue

What is the problem.... load the page using Webbrowser control of your windows application and invoke the items which you need to get the querystring...

For example :

Say I add a Webbrowser control on my form,

now during form load I pass
wbrowser.Navigate(new Uri("http://codeproject.com"));

Next I navigate to an article. You might invoke browser buttons to navigate. Finally to get the querystring you use :
wbrowser.Url.Query

I hope this is what you needed. Rose | [Rose]

Next time post in right section.
