参考

如果要cookie记住密码，参考，可以设置存放时间的。（或者再用一个cookie记录登陆日期）

谢谢有点甜老师！
如下面处理也能实现我想要的对应图片名，但是图太小看不清
Dim e As RequestEventArgs = args(0)
Dim wb As New WeUI
wb.AddPageTitle("","pageheader","WeUI","微信网页设计样式库")
With wb.AddGrid("","g1")
.Add("c1","", "./images/001.jpg").Attribute = "on click=\'jav ascript:alert(""c1"")\'"
.Add("c2","", "./images/002.jpg").Attribute = "on click=\'jav ascript:alert(""c2"")\'"
.Add("c3","", "./images/003.jpg").Attribute = ""
.Add("c4","", "./images/004.jpg").Attribute = ""
.Add("c5","", "./images/005.jpg").Attribute = ""
.Add("c6","", "./images/006.jpg").Attribute = ""
.Add("c7","", "./images/007.jpg").Attribute = ""
.Add("c8","", "./images/008.jpg").Attribute = ""
.Add("c9","", "./images/009.jpg").Attribute = ""
.Add("c10","", "./images/010.jpg").Attribute = ""
.Add("c11","", "./images/011.jpg").Attribute = ""
.Add("c12","", "./images/012.jpg").Attribute = "on click=\'jav ascript:alert(""c12"")\'"
End With
e.WriteString(wb.Build)
如果能点击获取一楼图片的文件名，我就能实现我想要的验证

水平有限,采用特笨的办法实现,分享给初学的狐友:
Select Case e.Path
Case "logon.htm",""
Functions.Execute("logon",e)
Case "logon_yz.htm"
Functions.Execute("logon_yz",e)
Case Else
Dim usernam As String=""
Dim Password As String=""
If e.Cookies.ContainsKey("usernam") Then
usernam= e.Cookies("usernam") \'从cookie中获取用户名
Password= e.Cookies("password") \'从cookie中获取用户密码
End If
If Password>"" AndAlso usernam>"" Then
Dim d2 As Date = Date.now
If e.Cookies.ContainsKey("dlsj") Then
Dim d1 As Date = e.Cookies("dlsj") \'获取上次登陆时间
Dim t As TimeSpan = d2 - d1
If t.TotalMinutes>150 Then \'如果距上次登陆时间超过150分钟则图片验证
Functions.Execute("logon_yz",e)
Return
End If
Else \'如果新打开浏览器则图片验证
Functions.Execute("logon_yz",e)
Return
End If
e.AppendCookie("dlsj",d2) \'保存登录时间以备用
Select Case e.Path
Case "xs_xzml.htm"
Functions.Execute("xs_xzml",e)
Case "xs_list.htm"
Functions.Execute("xs_List",e) \'分页显示
End Select
Else \'如果密码登陆超过3天清空了,则重新登陆
