DiminiPath,iniFileName,iniStr,tmpStr,n
DimuserName,passWord,tmp

userName=myfso222用户名
passWord=awaysrain密码
tmp=ai随机生成两个小写字母，（应该是随机生成的，但是我这里省略了）
passWord=tmp&UCase(md5(passWord))密码，是MD5加密过的，用动网的MD5加密程序，具体算法是随机生成两位小写字母，然后和你的密码连接后进行MD5加密，把随机生成的密码和MD5加密后的结果作为密码存放，举个例子来说比如下面的awaysrain用户，我的密码为awaysrain先随机生成两位小写字母ai，和我的密码awaysrain连接得到aiawaysrain把aiawaysrain进行MD5加密得到9118BFD94A9CE9CF37AE5BAA947ED596把随机生成两位小写字母ai和MD5加密后的结果9118BFD94A9CE9CF37AE5BAA947ED596连接得到密码ai9118BFD94A9CE9CF37AE5BAA947ED596

生成新的临时INI文件

DoWhilenotServUIni.AtEndOfStream
tmpStr=ServUIni.ReadLine

IfInstr(awaysrain&tmpStr,awaysrainUser)>0Then
记录用户原来的数量
n=n+1
EndIf

IfInstr(awaysrain&tmpStr,awaysrain[USER=)>0andnotaddedUserListThen
往用户列表的部分添加现在的用户
n=n+1
tf.WriteLine(User&n&=&userName&10)

EndIf
tf.WriteLine(tmpStr)
Loop
ServUIni.Close

添加新用户的信息，具体内容可以在SERV-U中新建用户并对照INI文件

tf.WriteLine([USER=&userName&1])用户名
tf.WriteLine(Password=&passWord)密码
tf.WriteLine(HomeDir=e:\temp)主目录
tf.WriteLine(RelPaths=1)是否锁定用户于主目录
tf.WriteLine(MaxUsersLoginPerIP=1)相同IP同时登录数
tf.WriteLine(SpeedLimitDown=102400)最大下载速度
tf.WriteLine(TimeOut=600)空闲超时时间（秒）
tf.WriteLine(Access1=E:\TempRLP)可访问目录,可以不是一个，比如Access2=E:\Temp1RLP

tf.Close

注：以上代码假设ServUDaemon.ini中的格式只有一个域并已经至少有一个用户

测试的ServUDaemon.ini文件结构如下：
