class="FocusMe">最近做一个指纹采集和比对的功能,因为公司整个项目是WEB类型的,所以指纹采集的模块要嵌套在网页中,那只有用ActiveX了,以下是一些操作及效果,做个笔记!
新建用户控件,编写CS代码,如下:
? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118

指纹采集关键代码:

指纹校验部分,最后保存起来的指纹是转换之后的BASE64字符串
