> ## How to access to the member instances

> ### How to access to the member instances in the class event procedures

> To access to the member instance, the instance needs to be defined as "member" of the user defined class. See [Class application window: chapter [How to make a instance be member]]
> The following shows a sample of a user defined class: sample.
> The variable: sample* base is the pointer of the sample class. Then you can access to the member instance: base->newvlab000 which name is newvlab000 for example.

>     #include <sample.h>
>     void sample::event_procedure(WSCbase* object){
>       sample* base = (sample*)object->getUserData(WS_BASE_CLASS);
>       ...

>       //Access the member instance...
>       WSCvariant val = base->newvlab000->getProperty(WSNuserValue);
>        ...
>     }

> ### How to access to the member instances in the method

> To access to the member instance in the class event procedure, it needs "base->", but in the method, it does no need "base->".
> The following is the sample of a user defined class: sample. Then you can access to the member instance directly: newvlab000 which name is newvlab000 for example.

>     //a sample of the method.
>     void sample::method1(long data){
>       newvlab000->setProperty(WSNuserValue,data);
>       ...
>     }
