Windows resource/.rc, .h files and GDI Functions, Fonts & Bitmaps

[SHC]

Hi all,
I saw the following 2 files used in the OpenGL and DirectX 9 programming:
1) resource.h
//{{NO_DEPENDENCIES}}
// Microsoft Visual C++ generated include file.
// Used by dx9_indexed_geometry.rc
//
#define IDC_MYICON 2
#define IDD_DIRECTX_DIALOG 102
#define IDD_ABOUTBOX 103
#define IDS_APP_TITLE 103
#define IDM_ABOUT 104
#define IDM_EXIT 105
#define IDS_HELLO 106
#define IDI_DIRECTX_ICON 107
#define IDC_DIRECTX_MENU 108
#define IDC_DIRECTX_ACCELERATOR 109
#define IDC_DIRECTX 110
#define IDR_MAINFRAME 128
#define IDC_STATIC -1

// Next default values for new objects

Issue #1: I do not know how the numerical numbers are decided and used in 1).
Issue #2: I have a hard to do the coding to create the .rc file like 2) for
Icon, Menu, Accelerator, Dialog, TEXTINCLUDE, etc.
Issue #3: Chapter 6 of Book "Programming with Microsoft Visual C++ .NET"
(Core Reference) by G. Shepherd with D. Kruglinski teaches Classic GDI
Functions, Fonts, and Bitmaps used in MFC. I do not know whether these GDI
Functions, Fonts and Bitmaps are related to the .rc file for Icon, Menu,
Accelerator, Dialog, TEXTINCULE, etc. Please help and address the
above-mentioned 3 issues for me or point out where I can find the answers for
them.

Thanks in adanve,
