vb.net Containers in vb6 using Interop Forms Toolkit 2.0

[gfahd]

Hello,
In order to make my vb6 apps Unicode, I am using Interop Forms Toolkit 2.0 for many controls. All going well until i tried to Use the TabControl and the Group Box control. They don't act as containers in vb6. Any help resolving this issue will be appreciated. Thanks

Are you sure you actually need the InterOp Forms Toolkit here, just for Unicode ¿
