Function gen_key(digits)
定义并初始化数组
dim char_array(80)
初始化数字
For i = 0 To 9
char_array(i) = CStr(i)
Next
初始化大写字母
For i = 10 To 35
char_array(i) = Chr(i + 55)
Next
初始化小写字母
For i = 36 To 61
char_array(i) = Chr(i + 61)
Next
Randomize 初始化随机数生成器。
do while len(output) < digits
num = char_array(Int((62 - 0 + 1) * Rnd + 0))
output = output + num
loop
设置返回值
gen_key = output
End Function
