   UINT  CALLBACK ESToolBarVers	( VOID );
   Retrieves a version number of DLL.
   DLL version.

   Parameters:
      NONE.
   Returns:
      DLL version number, in hexadecimal. Current version is 1.01,
      this function returns 0x101. For example for the version
      3.21 it will return 0x321.

   Creates a tool bar control.

   Parameters:
      hInst:		Instance handle (must be an instance of application,
			NOT library);
      lpszTemplate:	Pointer to the null terminated name of the TB template.
      hwndParent:	Parent window of the TB control.
      pntPosition:      Initial position of the TB control. Pay attention,
			is is a POINT struct itself, not a pointer, do not
			try to supply NULL.
   Returns:
      On sucsess returns a window handle of the TB control, NULL otherwise.

   Parameters:
      hwnd:		Window handle of the TB control to be destroyed
   Returns:
      On sucsess returns TRUE, FALSE otherwise.

/*
   int  CALLBACK GetButtonNumber( HWND hwnd, UINT nId );
   Retrieves the button number from it's ID number,
   analogous to GetDlgItem except that the TB buttons
   are not individual windows and consequently do not have
   handles.

   Parameters:
      hwnd:	TB window handle;
      nId	Button ID (equal to the wParam of WM_COMMAND from
		the corresponding button, or second parameter (tbsMsg)
		in the TB resource).
   Returns:
      Button number, which can be used to change button's state or style.
      If no button with such ID exists function returns -1. If several
      buttons share the same ID it returns first it encounters.
