Hi there, we have a lot of users' login/password info from another application now trying to migrate to our DNN application. with all the necessary info & settings (userid, password, passwordformat set to clear, etc.), we could insert those users into the DNN application. the way how we do that is by inserting rows in the following 7 tables in such order:
aspnet_Users, aspnet_Profile, aspnet_Membership,aspnet_UsersInRoles,Users,UserRoles,UserPortals

all fields were nicely formatted and filled in except aspnet_Profile.PropertyValuesBinary which is an image field and we can't figure out how and what to fill in..

 the user could actually login. HOWEVER, those 'implanted' users cannot do anything like regular registered user and when login as host to view Admin -> User account fcn, the screen throws the following errors:


Error: User Accounts is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Data is Null. This method or property cannot be called on Null values. ---> System.Data.SqlTypes.SqlNullValueException: Data is Null.

I've checked the aspnet_Profile table in my database and the PropertyValuesBinary does not allow nulls. The low level work with the DB is allways very difficult.
  I suggest you to look at the admin/Users/manageusers.ascx.vb the cmdUpdate_Click event handler. There is a block of code doing the work to register a user (lines 327-372 in DNN4.02). I suppose you can serialize your old DB as XML and write a custom module using similar code to register the users like the DotNetNuke itself does instead of working with the aspnet memship tables.

  Best Regards
