OK, I'm making a program that pulls information out of a DaniWeb Profile page using a WebBrowser. However, it's frankly getting annoying having to click "Member log-in" each time, and this is something you'd do multiple times a day, possibly with different accounts. So, I thought, why not have it pop up the box automatically? Some digging into the HTML revealed this:
<a
href="/forums/register.php" id="loginlink">Member
Log In</a>
<!--Annnd a little while later... -->
<script type="text/javascript"> <!--
$(function() {
$('a#loginlink').bind('click', function() {
$("#loginform").dialog( { modal: true });
return false;
});
//--> </script>To my semi-trained eye, that looks like its intercepting the click event of the Login Link to show the custom dialog box. Great, I thought. I just need to simulate a click on that link.
Of course, the simple things never are. Here is the base code that triggers the box:
private void Form1_Load(System.Object sender, System.EventArgs e)
{
wbMain.ScriptErrorsSuppressed = true;
//// skip error messages.
ShowLoginBox();
}
private void ShowLoginBox()
{
wbMain.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wbMain_DocumentCompleted); //When the page loads, open login box.
wbMain.Navigate(urlDaniWeb);
}
void wbMain_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
try
{
//OK, this is where everything is failing (I separated different attempts):
//HtmlElement el = wbMain.Document.All["loginlink"];
//el.InvokeMember("Click");
//======================================================================
//HtmlElement el = wbMain.Document.All["loginlink"];
//el.InvokeMember("Click");
//object obj = el.DomElement;
//System.Reflection.MethodInfo mi = obj.GetType().GetMethod("click");
//mi.Invoke(obj, new object[0]);
//======================================================================
//HtmlElement btn = wbMain.Document.GetElementById("loginlink");
//btn.InvokeMember("click");
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
wbMain.DocumentCompleted -= wbMain_DocumentCompleted; //Unsubscribe, we don't want this going off like nuts
}Summary of the errors:
- InvokeMember("Click") returns NULL, I even varied the case of Click.
- System.Reflection.MethodInfo mi = obj.GetType().GetMethod("click"); mi is always NULL.
HOWEVER every method always successfully returns the link element, and manually clicking the link in the webbroswer does indeed bring up the box. As near as I can figure out, this link doesn't have the method "click"...?
