Hi !
  I made a component with two interfaces. I used the ATL wizards. Its a simple object only. Only the first interface is registered in the registry. I dont see the registry entry for the second! Hence, my CoCreateInstance fails when I try to create a pointer to the second interface! How do I ensure that the registry entry is made (Under Classes) for the second interface?

You can edit the object.rgs file in the project to add the second object.

You can use a tool likd GUIDgen to create a CLSID for the second object.

HKCR
{
      MyObject.Object1.1 = s 'Object Class'
      {
            CLSID = s '{FF01DABF-43C5-4B80-8696-FB81C6CBA74A}'
      }
      MyObject.Object1= s 'Object Class'
      {
            CLSID = s '{FF01DABF-43C5-4B80-8696-FB81C6CBA74A}'
            CurVer = s MyObject.Object1.1'
      }
      NoRemove CLSID
      {
            ForceRemove {FF01DABF-43C5-4B80-8696-FB81C6CBA74A} = s Object Class'
            {
                  ProgID = s MyObject.Object1.1'
                  VersionIndependentProgID = s MyObject.Object1
                  ForceRemove 'Programmable'
                  InprocServer32 = s '%MODULE%'
                  {
                        val ThreadingModel = s 'Apartment'
                  }
                  'TypeLib' = s '{5BC2EA21-81ED-44CE-ADDA-02ABE29790B8}'
            }
      }
               MyObject.Object2.1 = s 'Object Class'
      {
            CLSID = s '{AF01DABF-43C5-4B80-8696-FB81C6CBA74A}'
      }
      MyObject.Object2= s 'Object Class'
      {
            CLSID = s '{AF01DABF-43C5-4B80-8696-FB81C6CBA74A}'
            CurVer = s MyObject.Object2.1'
      }
      NoRemove CLSID
      {
            ForceRemove {AF01DABF-43C5-4B80-8696-FB81C6CBA74A} = s Object Class'
            {
                  ProgID = s MyObject.Object2.1'
                  VersionIndependentProgID = s MyObject.Object2
                  ForceRemove 'Programmable'
                  InprocServer32 = s '%MODULE%'
                  {
                        val ThreadingModel = s 'Apartment'
                  }
                  'TypeLib' = s '{ABC2EA21-81ED-44CE-ADDA-02ABE29790B8}'
            }
      }
}

Good Luck!
