═══ 1. Extended Help for the worplace window ═══

The demo program has a fully working help support. You just have to select a 
menu item, press F1 and you will see the related application code. 


═══ 2. File Open Help ═══

When you select this option, you will create a primary window, that was created 
with the help of the PrimaryWindow Class. It is good programming style is you 
hide the use of the function SeiCreateDialogWindow in a creation function. 

In the following you see the entire creation function. 

HWND EXPENTRY CreateDummy ( HWND hwnd, PVOID pParamDummy) {
  USHORT  usrc;
  HMODULE hModule;
  HWND    hwndFrame;
  usrc = DosGetModHandle (DLL_NAME, &hModule);
  hwndFrame = SeiCreateDialogWindow (HWND_DESKTOP,      // Parent
                                     hwnd,              // Owner
                                     WS_VISIBLE,        // Frame style
                                     NULL,              // FCF
                                     DlgWinProc,        // WinProc
                                     NULL,              // Title
                                     hModule,           // Resource
                                     DLG_MAIN,          // ResourceID
                                     pParamDummy);
  return (hwndFrame);
  }

The function was invoked in the window procedure of the client window of our 
workplace during the handling of the WM_CREATE message. 

Here is the code: 

        case MN_FILEOPEN: {
             HWND      hwndDummy;
             /*--------------------------------------*/
             /* Create a primary or secondary window */
             /*--------------------------------------*/
             hwndDummy = CreateDummy (hwnd, "Charly Brown");
        } break;


═══ 3. File Exit Help ═══

When  you  select  the  exit  option ,  a  WM _ QUIT  message  is  posted . 

        case MN_FILEEXIT: {
             WinPostMsg (hwnd, WM_QUIT, 0L, 0L);
        } break;
