hi
my project requires to create user and update user programmatically.
i am able to create and update user but my question is how to find the user is updated means user updated status.
in dnn api its showing

public static UserCreateStatus CreateUser(ref UserInfo objUser);
public static void UpdateUser(int portalId, UserInfo objUser);

so CreateUser method has return type of "UserCreateStatus" to find the user is created or not

but UpdateUser method doesnot have any return type how can i find user is successfully updated or not?

Unlike the CreateUser() api call - Its technically almost impossible for an UpdateUser call to fail if a valid userinfo object is passed into it.

If the update were to fail in any way, it would be because of a serious error - and as such  - would cause a system exception.

The CreateUser() api call does a lot of different testing to before a user is created - all of which can possibly produce different UserCreateStatus values.  

In some ways - it could be considered bad coding design to surface these as a UserCreateStatus values - if you were following the asp.net exception processing guidelines - where the norm would be for each UserCreateStatus to throw an exception which would be handled by the normal try/catch processing system.

But regardless - for now if you need to test for a FAILED UpdateUser() call
 - wrap the call in a try/catch - if it fails an exception will be generated - by the low level dataprovider calls.
