System.Diagnostics.Process.Start("iexplore", "http://example.com");

Answer 3

There is a way to open a page in default browser System.Diagnostics.Process.Start(url);

If you want specifically to open it in IE you will probably need to create a new IE process with URL as an argument.

UPD: If you want to run a function, insert GET parameters into your url string (ie. http://stackoverflow.com/page?runFunction=1) and in your application code check for runFunction parameter and based on its value decide if your application needs to run the function.

I don't think is possible to specify new IE window width and height values, you may need to use javascript for that.
