HI guys,
I am creating an Permission Repository and this code is from my book.

C#

public void SavePermission(Permission permission)
{
    using(FisharooDataContext dc = Connection.GetContext())
    {
      if(permission.PermissionID > 0)
      {
         <u>dc.Permissions.Attach(permission,true);</u>
      }
      else
      {
        <u> dc.Permissions.InsertOnSubmit(permision);</u>
      }<u>
      dc.SubmitChanges();</u>
     }
}

I get error when i use dc.Permissions.Attach(permission,true).. it gives me an error saying it cant take more than 2 arguments.

AND

when is try using

C#

dc.Permission.InsertOnSubmit(permission);

and

C#

dc.SubmitChanges();

my visual studio's intellisense cannot recognize InsertOnSubmit or SumbmitChanges

maybe i should use an using statment but i dont kno which!

and i even reffered my code to this webpage
http://code.google.com/p/eboxshowsns/source/browse/trunk/EboxShowSNS.Core/DataAccess/Impl/PermissionRepository.cs?spec=svn6&r=6[^][^]

but i dont find any differences.

Please help me out with my above 3 mentioned problems.

Thank you.

For the InsertOnSubmit and SubmitChanges issues, did you look to see if you have
using System.Data.Linq?

is this a typo?
dc.Permissions.InsertOnSubmit(permission);
I'm sure it is as the code above and on the linked source says so.

I assume that your (Connection)conn.GetContent returns a System.Data.Linq.DataContext instance? If this has been instanciated then why would you need to attach a record to it when the record already exists? Are you using some form of data caching? The way that changes to a specific record would be acheived is to select the record out of the table, update eacha and every property and then just dc.SubmitChanges() (I think :S)

Are you sure that the "Permissions" table has a capital P as automatically generated dbml files usually put this to lower case, as with the entity type "permission"

If I have all of this wrong then please post the proof in code as there may be a small error there you have missed.

Hope this is useful ;)
