Yassin,

>My application overrides mmDatabaseManager and works fine for all my business object, know I want to use mmuserloginForm, mmuserForm, mmRoleForm, but want to put the security tables in a different database.

You can specify the SecurityDatabaseKey setting in your app.config file. Check out the MM .NET Dev Guide topic "Enabling User Security in a Windows Forms Application | Step 2 - Specifying the Security Database" for details.
