Unfortunately I have to talk to a 16 bit app.  I have gotten to the point
where I send  a WM_COPYDATA message to a 32 bit and it works great.  But
when I reversed the process of sending a WM_COPYDATA message to the 16 bit
app I get garbage in the data pointer.  I have checked the 32bit app and it
works fine with a 32bit app.  I'm sure I'm doing something wrong with the
pointers but I'm at a loss.

typedef struct tagCOPYDATASTRUCT
{
   DWORD dwData;
   DWORD cbData;
   VOID FAR *lpData;

          pMyCDS =  (LPCOPYDATASTRUCT) lParam;
          PtMyRec = pMyCDS->lpData;
         MessageBox(hWnd,(LPSTR)
PtMyRec->result,szAppName,MB_ICONSTOP|MB_OKCANCEL|MB_TASKMODAL);
          strcpy(MsgD, PtMyRec->result);
          dislog("Number is :%d",PtMyRec->x);
          dislog("%s",MsgD);
