3. [COLOR=Blue]SetClassLong   [/COLOR]
   
4. The SetClassLong function replaces the specified 32-bit (long) value at
   
5. the specified offset into the extra class memory or the WNDCLASS
   
6. structure for the class to which the specified window belongs.
   
7. 
   
8. DWORD SetClassLong( HWND hWnd,
   
9. // handle of window
   
10. 
    
11. int nIndex,
    
12. // index of value to change
    
13. 
    
14. LONG dwNewLong
    
15. // new value
    
16. 
    
17. );
    
18.   
    
19. 
    
20. 
    
21. Parameters
    
22. hWnd
    
23. 
    
24. Identifies the window and, indirectly, the class to which the window belongs.
    
25. 
    
26. nIndex
    
27. 
    
28. Specifies the 32-bit value to replace. To set a 32-bit value in the extra
    
29. class memory, specify the positive, zero-based byte offset of the value to
    
30. be set. Valid values are in the range zero through the number of bytes of
    
31. extra class memory, minus four; for example, if you specified 12 or more
    
32. bytes of extra class memory, a value of 8 would be an index to the third
    
33. 32-bit integer. To set any other value from the WNDCLASS structure,
    
34. specify one of the following values: Value
    
35. Action
    
36. 
    
37. GCL_CBCLSEXTRA
    
38. Sets the size, in bytes, of the extra memory associated with the class.
    
39. Setting this value does not change the number of extra bytes already allocated.
    
40. 
    
41. GCL_CBWNDEXTRA
    
42. Sets the size, in bytes, of the extra window memory associated with each
    
43. window in the class. Setting this value does not change the number of
    
44. extra bytes already allocated. For information on how to access this
    
45. memory, see SetWindowLong and SetWindowWord.
    
46. [COLOR=Red]
    
47. GCL_HBRBACKGROUND
    
48. Replaces the handle of the background brush associated with the class.   //use it!
    
49. [/COLOR]
    
50. GCL_HCURSOR
    
51. Replaces the handle of the cursor associated with the class.
    
52. 
    
53. GCL_HICON
    
54. Replaces the handle of the icon associated with the class.
    
55. 
    
56. GCL_HMODULE
    
57. Replaces the handle of the module that registered the class.
    
58. 
    
59. GCL_MENUNAME
    
60. Replaces the address of the menu name string. The string identifies the
    
61. menu resource associated with the class.
    
62. 
    
63. GCL_STYLE
    
64. Replaces the window-class style bits.
    
65. 
    
66. GCL_WNDPROC
    
67. Replaces the address of the window procedure associated with the class.
    
68. 
    
69. 
    
70. 
    
71. dwNewLong
    
72. 
    
73. Specifies the replacement value.
    
74. 
    
75. Return Values
    
76. If the function succeeds, the return value is the previous value of the specified 32-bit integer.
    
77. 
    
78. If the function fails, the return value is zero. To get extended error information, call GetLastError.
    
79. 
    
80. Remarks
    
81. If you use the SetClassLong function and the GCL_WNDPROC index to
    
82. replace the window procedure, the window procedure must conform to
    
83. the guidelines specified in the description of the WindowProc callback function.
    
84. 
    
85. Calling SetClassLong with the GCL_WNDPROC index creates a subclass
    
86. of the window class that affects all windows subsequently created with
    
87. the class. An application should not subclass a window created by another process.
    
88. 
    
89. Reserve extra class memory by specifying a nonzero value in the
    
90. cbClsExtra member of the WNDCLASS structure used with the
    
91. RegisterClass function.
    
92. 
    
93. Use the SetClassLong function with care. For example, it is possible to
    
94. change the background color for a class by using SetClassLong, but this
    
95. change does not immediately repaint all windows belonging to the class.
    
96.

3. The CreateSolidBrush function creates a logical brush that has the specified solid color.
   
4. 
   
5. HBRUSH CreateSolidBrush( COLORREF crColor
   
6. // brush color value
   
7.

15. Specifies the color of the brush.
    
16. 
    
17. Return Values
    
18. If the function succeeds, the return value identifies a logical brush.
    
19. 
    
20. If the function fails, the return value is NULL.

22. Remarks
    
23. A solid brush is a bitmap that Windows uses to paint the interiors of filled shapes.
    
24. 
    
25. After an application creates a brush by calling CreateSolidBrush, it can
    
26. select that brush into any device context by calling the SelectObject function.
