32. 　　);
    
33. 　　Parameters
    
34. 　　 　　[in] hIcon
    
35. 　　Handle to the icon that contains the bitmap and mask for the new image.
    
36. 　　[in] bAutoDestroy
    
37. 　　TRUE to specify that bitmap resources be destroyed automatically; otherwise, FALSE. The default is TRUE.
    
38. 　　[in] hIconHot
    
39. 　　Handle to the icon that contains the image for the selected state.
    
40. 　　[in] hBitmap
    
41. 　　Handle to the bitmap that contains the image for the non-selected state.
    
42. 　　[in] hBitmapHot
    
43. 　　Handle to the bitmap that contains the image for the selected state.
    
44. 　　[in] uiBmpResId
    
45. 　　Resource ID for the non-selected image.
    
46. 　　[in] uiBmpHotResId
    
47. 　　Resource ID for the selected image.
    
48. 　　[in] bMap3dColors
    
49. 　　Specifies a transparent color for the button background; that is, the face of the button. TRUE to use the color value RGB(192, 192, 192); FALSE to use the color value defined by AFX_GLOBAL_DATA::clrBtnFace.
    
50. 　　[in] hIconDisabled
    
51. 　　Handle to the icon for the disabled image.
    
52. 　　[in] hBitmapDisabled
    
53. 　　Handle to the bitmap that contains the disabled image.
    
54. 　　[in] uiBmpDsblResID
    
55. 　　Resource ID of the disabled bitmap.
    
56. 　　[in] bAlphaBlend
    
57. 　　TRUE to use only 32-bit images that use the alpha channel; FALSE, to not use only alpha channel images. The default is FALSE.
    
58. 　　Example
    
59. 　　 　　The following example demonstrates how to use various versions of the SetImage method in the CMFCButton class. The example is part of the NewControls Sample: MFC Controls Demonstration Application.
    
60. 　　VBC#C++F#JScriptCopyCMFCButton m_Button;
    
61. 　　...
    
62. 　　// int m_iImage
    
63. 　　// IDB_BTN1_32, IDB_BTN1_HOT_32, IDB_BTN1, IDB_BTN1_HOT are int macros that are #define.
    
64. 　　if (m_iImage == 1)
    
65. 　　{
    
66. 　　m_Button.SetImage((HBITMAP) NULL);
    
67. 　　}
