SHDocVw.InternetExplorer & SHDocVw.ShellWindows

Question

Hi !

I'm trying to open internet explorer and show a web page on it .
I also want to post some data to the web page.
My problem is that I don't want to reopen a new web browser for the same URL. I want to reuse the same web browser and post some data to that url again.
I want to use the same web browser.
I tried to use SHDocVw.InternetExplorer and SHDocVw.ShellWindows.
This is what i can do so far.

SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.Visible = false;
ie.Navigate2(ref vUrl, ref vFlags, ref vTargetFrame, ref vPost, ref vHeaders);

Is there anybody can help me ?

Thanks
