How do you wait for an IE process to finish when started with Process.Start()

I am developing a WinForm application which will redirect theuser to HTML page, using IE, when they click a button. However,I want this to be modal in operation, so I would like to makesure that the IE process has finished before I allow then tocontinue.

I first tried using the WaitForExit method of the Process class,but this returns an error while IE is still showing the HTMLpage. Is there any way that I can ensure the page is closedbefore allowing the user to continue?

If possible, I would like to stay away from using an embeddedbrowser control as this looks a little bit too complex for whatI am trying to achieve.

A code sample is below

ProcessStartInfo startupInfo = new ProcessStartInfo ();
startupInfo.FileName = filePath;
startupInfo.UseShellExecute = true;
startupInfo.CreateNoWindow = true;
Process process = Process.Start (startupInfo);
process.WaitForExit();

The filePath variable is the fully qualified path to a HTMLdocument. By the time the WaitForExit is called, an Objectreference not set exception is thrown.

Thanks in advance
 
Hi Stephen,

I think that this will be a hard way to go, the user can open another window
in IE or a page can do that for him.

Why not building your own webbrowser with limited browser capabilities.

It is almost here already completly for you.
