I want to access some site , say gmail or twitter from my application. The application should fill my username and password and submit the form and post some updates from the application itself. Here is some code . Help would be appreciated

protected void Button1_Click(object sender, EventArgs e)
{
Object obj = null;
Object URL = "www.gmail.com";
InternetExplorer iexp = new InternetExplorer();
iexp .Visible = true;
iexp .Navigate2(ref URL, ref obj , ref obj , ref obj , ref obj );
//iexp .Navigate("http://www.gmail.com", ref obj , ref obj , ref obj , ref obj );

while (iexp .Busy)
{
System.Threading.Thread.Sleep(50);
}

mshtml.HTMLDocumentClass dclass = (mshtml.HTMLDocumentClass)iexp .Document;


mshtml.HTMLInputElementClass eclass= (mshtml.HTMLInputElementClass)dclass.all.item("email", null);
eclass.value = "username";


eclass= (mshtml.HTMLInputElementClass)dclass.all.item("Passwd", null);
eclass.value = "password";

eclass= (mshtml.HTMLInputElementClass)dclass.all.item("signIn", null);
eclass.click; 
}

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

I believe the error that you are referring to is related to permission. Check your IIS policy
