#include "TNSRemoteInterfaceDll.h"

LPARAM GetUniqueID()
{
    //generate unique ID
    static LPARAM id = 0;
    if (++id == 0) ++id; // do not use 0 !!!!!
    return id;
}

inline LRESULT RI_MESSAGE( const UINT request, HWND h_client, LPARAM id )
{
    //check if RI handle is valid
    if ( !IsWindow( RI_GetTNS() ) ) 
        return RI_NAVIGATIONNOTACTIVE;
    //send the request
    PostMessage( RI_GetTNS(), request, WPARAM(h_client), id );
    return RI_NOERROR;
}
