here it is

object o=null;
foreach(Match m in Matchescollection)
{

awxWebBrowser.navigate("http://192....."+m.value().tostring(),ref o,ref o,ref o,ref o)

}

here Matchescollection contains all the links i.e.
and on each match in the collection i want the Internet explorer to go to that link. for this i have used the m.value() concatenated with the IP of the site (here IP is permanent).

this is what i want to have. now the problem is once it enters loop it just get all the values and concat them and then , as there is no time for displaying page, it just shows the last page. i.e. last link's page.
i just want to have this delay so that it shows a page then again uptill the last page.

From your description, it sounds like the reason your code doesn't work as expected is because the loop is running on the server and is thus starting over each time. I have two that you could try, both are client-side javascript:

Window.setTimeout(code, delay) - A string of script to execute after millisecods delay has expired. You could call a function that keeps track of which page to display next. setTimeout fires only once, so your function will have to reregister call setTimeout() as well.

Window.setInterval(code, interval)
Window.setInterval(func, interval, args...) - Similiar to setTimeout, but repeats perpetually. The second overload may be the most appropriate for your problem.

Remember that Thread.Sleep() takes time in milliseconds. This executes on the current thread, so there's no reason that Thread.Sleep(30000) shouldn't sleep for 30 seconds.

? MEAN WHAT ?
i have wrote the code below.

here it is

object o=null;
foreach(Match m in Matchescollection)
{

awxWebBrowser.navigate("http://192....."+m.value().tostring(),ref o,ref o,ref o,ref o)

}

here Matchescollection contains all the links i.e.

i just want to have this delay so that it shows a page then again uptill the last page.

it's not doing that

As I said, the loop is flying through in mere milliseconds. You must put Thread.Sleep(30000) (30 seconds here, for example) after you navigate. For one, navigate is a non-blocking call so each iteration doesn't wait for the next to finish. Second, even if it was a blocking call, you still wouldn't have enough time to read the page. How is this hard to understand?

Yes, it'll work. It's supposed to work. If it didn't, there were be many things wrong with your entire system. Read the documentation for Thread.Sleep. The call will block for the specified time, giving the WebBrowser control enough time to load the page and you to read it, and then the method will return and the next iteration will continue. This is a simple problem.

Combo Box Values

How is it possible to use a combo box, that has two values, Yes and No, and depending on which one a user selects, must equal 0 or 1.

To add to this, the combo box is bound to a dataTable where the values it receives are either 0 or 1.

I cannot seem to work this out. I saw the Addrange method, and thought that might be what I want, but MSDN has very little in the way of usefull information on this. Please help me.

Well if you getting the information from a database then you could simply add the strings "No" and "Yes" to the comobobox and then use the selected index property to select the correct string. For example if you're reading in the data from the database and the value you get is 0 then that would set the comobobox to index 0 (or the string "No")

Sorry, I dont want to sound stupid, but I am, as I dont really understand how thats done. I can understand setting the selected index, but how would you tell the control to use Yes and No, and to bind those respective values to 1 and 0.
