I am writing a program which allows me to log in to my favorite forum, and displays me my fav. threads, and automatically refreshes current thread every 30 seconds or so.For this, I first need to login to the forum page. Fortunately, the forum allows to login during posting a new message, and it's a public forum so browsing threads is possible without login. Therefore I can directly jump to the "edit article" page without login, fill in login information and write the post, and then send it altogether. Here is an example link for that:
[URL]
Here comes my problem. I have searched for autofilling values and my code is like this:
Dim mydoc As HtmlDocument = sender.Document
Dim mynickname As HtmlElementCollection = mydoc.Forms("f").GetElementsByTagName("input").GetElementsByName("nickname")
Dim mypass As HtmlElementCollection = mydoc.Forms("f").GetElementsByTagName("input").GetElementsByName("pass")
If mypass.Count > 0 Then

I guess it doesn't set the value attribute, at least during debugging the 'outerHTML' property stays like this:
"<INPUT class=form_input type=password value="" name=pass>"
While a web page -which needs login- is opened in my browser, if I close browser and re-open, I have to write username password again. But, sometimes when I close browser and re-open for the same page, it isn't needed username and password again? Is it about Session, Cookie? If yes, why are there different conditions?

View 5 RepliesI have a form just like the login form in VB.Net. The usernames are prepopulated on a combobox with datas from the SQL DB backend, and the text box for the password entry is empty. My code is working but what I need help is, for the code to validate the username and password entered against that stored on the SQL DB backend. Like when the user selectes a wrong username but the password entered is correct, there shld be a messagebox like "The username selected is wrong", or if the username is correct and the password entered is wrong then the msg is "The password entered is not correct, please type you password using the right case".
