Randomize
\’ 用Randomize生成随机种子.
For i = 1 to 7
\’ 循环7次，即创建7位随机密码.
intNum = Int(10 * Rnd + 48)
\’ 0-9的ASCII码范围是48-57.
intUpper = Int(26 * Rnd + 65)
\’ A-Z的ASCII码范围是65-90.
intLower = Int(26 * Rnd + 97)
\’ a-z的ASCII码范围是97-123.
intRand = Int(3 * Rnd + 1)
\’ 对Int(3 * Rnd + 1)取整得到intRand,会有3种结果,用select case判断当前的intRand值是1,2还是3.如果是1显示数字,是2显示大写字符,是3则显示小写字符.
Select Case intRand
Case 1
strPartPass = Chr(intNum)
\’ 用Chr方法换算到对应的ASCII值.
Case 2
strPartPass = Chr(intUpper)
Case 3
strPartPass = Chr(intLower)
End Select
genPassword = genPassword & strPartPass
Next
randomPassword = genPassword
\’ 将创建的密码保存在变量randomPassword中.
