Dear Friends,
Very Thanks
we have a DNN site which is working perfect . I created an Android application with a login screen recently with some of our personnel modules .Now my requirement is whenever user clicks on Login Button, It should check the DNN table username and Passwd and need to check the user credential correct or nt?
How can I do that???

Do you want to authenticate the login to the Android application using the username and password from your DNN site?
If so, I think that the best way to do this would be to create a webservice in your DNN installation that you can call from the Android application. When you click the login button in the Android application, the result would be to call the webservice to get a yes/no answer for authentication.
You will want to have the latest version of DNN to do this.
There are modules available that simplify the process of creating webservices in DNN. I believe that DNNSharp.com has one. Also, the module from
http://2sxc.org/.

Generally, it's a very bad practice to return a username/password.
The way that DNN works is verify that a password entered by the user "matched" the stored password. It does this by encrypting or hashing (depending on the password format) the submitted password, and comparing that to the stored value which is encrypted or hashed.
This is the only way that this can be done if using the hashed password, as the hashing is a "one-way" function. You cannot unhash a hashed password.
This is also the most secure approach, which is very important in these days of needing to protect user data.
When passing a passwor to a webservice, the password should also be protected!

Dear Joe,
I tried the below service function.But always I am getting value as "False" even I pass correct username and passwd.Anything wrong in this?
Public Function GetUserAuthenti(ByVal userid As String, ByVal password As String) As String
Dim AuthUser As String = "True"
Dim loginStatus As New DotNetNuke.Security.Membership.UserLoginStatus
Dim user As UserInfo = UserController.ValidateUser(0, userid, password, "", "", "0.0.0.0", loginStatus)
If user Is Nothing Then
AuthUser = "False"
End If
Return AuthUser
End Function

Dear Joe,
I solved my issues when I passed my portalID correctly.
Dim AuthUser As String = "True"
Dim loginStatus As New DotNetNuke.Security.Membership.UserLoginStatus
Dim user As UserInfo = DotNetNuke.Entities.Users.UserController.ValidateUser(2, userid, password, "DNN", "sitename.com", "Enter Correct IP", loginStatus)
If user Is Nothing Then
AuthUser = "False"
End If
Return AuthUser
