IPB_Session interface:

GetNativeInterface method

Description

Obtains a pointer to the interface of a native class.

Syntax

GetNativeInterface(pbobject obj)

Argument	Description
obj	A valid object handle

Return Values

IPBX_UserObject.

Examples

This example invokes the function f_retrieve in the native class Cmy_pbni to retrieve a DataWindow object:

long f_retrieve(IPB_Session* session, pbint iarg,
   pbobject dwObj, pbobject extObj)
{
   Imy_pbni* pImy_pbni = NULL;
   pblong lRet;
   if (session -> IsNativeObject(extObj) )
   {
      pImy_pbni = (Imy_pbni*) session ->
         GetNativeInterface(extObj);
 
      lRet = pImy_pbni-> f_Retrieve(session,
         iarg, dwObj);
   }
   return lRet;
}

Usage

Use this method in conjunction with IsNativeObject to obtain a direct reference to the IPBX_UserObject associated with a native class in the same PowerBuilder extension. The class and its methods can then be accessed directly.
