Đây lại là trang khác.

Bạn nên dùng các chức năng có sẵn của các trình duyệt để xem dữ liệu được gửi nhận như thế nào.
Trang http://ungvien.com.vn/employer/main.php có ô đăng nhập nhưng nó gửi sang trang ẩn là: http://ungvien.com.vn/employer/profile_common.php?tab=login

Mã:

<form style="margin:0" name="loginForm" method="post" action="profile_common.php?tab=login" onsubmit="return checkLogin(this,this.password);"><!-- ... --></form>

Đồng thời dữ liệu gửi của trang này:

Mã:

email:email@email.com
password:MyPassword
x:40
y:18
axn:1

x,y có thể là tọa độ của con trỏ chuột.

Bác chỉ ae cách xem trong trình duyệt đi , mình chưa biết cái này [IMG]images/smilies/biggrin.png[/IMG]

Với chrome thì bấm F12, bật qua tab Networks rồi xem các giá trị nó post ở khung bên phải.
Khi lấy nội dung trang chứa form lần đầu tiên, bạn nên lấy tất cả các input có giá trị (attr value) rồi post kèm những trường cần handle.

Một quá trình kinh khủng là phức tạp. Cách tốt nhất là làm WebBrowser1 rồi sau đó tìm txt fill in roi fire button login.
Vài cái cần lưu ý khi sử dụng, giữ browser object này lại để có thể navigate qua trang khác, brwoser rất good cho phần này nếu ASP.NET đó dùng ViewState thì nó cũng carry over.

HttpWebRequest req = WebRequest.Create("http://thuvienphapluat.vn/page/login.aspx") // View state issue

Nếu làm kiểu này req phải là dạng member (nằng trong memory (global) thay vì local variable), không thì after login thì Garbarge collector sẽ collect đi và khi navigate qua trang khác website nó sẽ báo là chưa LOGIN.
