  5. //-To use TRACER, follow these 5 steps.---------
  6. //----------------------------------------------
  7. //----1. Include this header in your program.---
  8. //       Includes necessary macros.
  9. //----------------------------------------------
  10. //----2. Add macro TRACERVARIABLES above main().
  11. //       Defines necessary variables / defines.-
  12. //----------------------------------------------
  13. //----3. Add macro TRACERHELLO in your WM_CREATE
  14. //       Put between WM_CREATE and break;
  15. //       Initiates handshaking with debugger.
  16. //----------------------------------------------
  17. //----4. Add macro TRACERATTACH in your WndProc.
  18. //       Put as a seperate case in your WndProc.
  19. //       Completes handshaking with debugger.
  20. //----------------------------------------------
  21. //----!!! When placing the TRACERATTACH in your-
  22. //--------window procedure, don't forget the----
  23. //--------break; statement after it. !!!--------
  24. //----------------------------------------------
  25. //----5. Use macro TRACER("string") freely.-----
  26. //       This is the debug statement.
  27. //----------------------------------------------
  28. //----Note:-------------------------------------
  29. //----You may need to include EXTERNTRACERVARS--
  30. //----in secondary modules if you want to call--
  31. //----TRACER from those modules.----------------
  32. //----------------------------------------------
  33.  
  34. //----------------------------------------------
  35. //-Note:----------------------------------------
  36. //----------------------------------------------
  37. //----In the TRACERHELLO macro, there is a param
  38. //----called hWnd.  You need to pass your window
  39. //----handle to me so that I can send mine back-
  40. //----to you.  You may need to change "hWnd" to-
  41. //----whatever your wndproc parameter name is---
  42. //----for window handle ( e.g. MyhWnd ).--------
