L_INT LContainer::Create (hwndOwner)
Creates a container and attaches it to a user defined window.
Handle of the window that owns the container.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
The container owner window should have CS_DBLCLKS in its class style. Otherwise some container functions will not work.
LContainer::Initialize must be called before calling this function.

This example shows the minimum requirements to start using some container.
