Visual Basic: Destroy Broker Components
When you are done using any TRPCBroker component, you should call its destroy method to free it from memory.
To destroy TRPCBroker components from your Visual Basic program:
1. Make sure the TRPCBroker component is not connected:
Call RPCBPropSet(intRPCBHandle, "Connected", "0")
2. Call the RPCBFree method to destroy the object:
RPCBFree(intRPCBHandle)
Visual Basic takes care of the details of unloading the DLL.
