Question

I’m looking for a way to make my program wait for a page to load completely, before it keeps going and executes more code on the loaded document.

I didn’t find any good way to do it, but I remembered that when we use MessageBox.Show("some string"); the program stops/waits(?) and then keeps going, even in a loop.

So when we have this loop:

for (int i = 0; i < 10; i++)
{
    MessageBox.Show("i");
}

the i++ will not run until I press the OK button.

How were they able to do that?

MessageBox.Show() displays a modal window. The call to MessageBox.Show() blocks until the dialog is dismissed by the user.
