有人愿意帮忙测试几行代码吗？
下面的这片代码是设置代理ip并且刷新的。可是我试了几次没有效果。在打开id的选项那边查看，发现并没有改变。
打开注册表 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings，查看ProxyServer的值发现也没有变化，不知道是怎么回事。我的是xp系统。

VB code

Option ExplicitPrivate Declare Function InternetSetOption Lib "wininet.dll" Alias "InternetSetOptionA" (ByVal hInternet As Long, ByVal dwOption As Long, ByRef lpBuffer As Any, ByVal dwBufferLength As Long) As LongPrivate Type INTERNET_PROXY_INFO        dwAccessType As Long        lpszProxy As String        lpszProxyBypass As StringEnd TypePrivate Const INTERNET_OPTION_PROXY = 38Private Const INTERNET_OPTION_SETTINGS_CHANGED = 39Private Const INTERNET_OPEN_TYPE_DIRECT = 1Private Const INTERNET_OPEN_TYPE_PROXY = 3     Private Sub SetProxy(aStrIP As String, aStrPort As String, aBolUseProxy As Boolean)    Dim strProxy As String    Dim inf As INTERNET_PROXY_INFO    aStrIP = Trim(aStrIP)    aStrPort = Trim(aStrPort)    If (aStrIP + aStrPort = "") Or Not aBolUseProxy Then       strProxy = ""    Else       strProxy = "http=" + aStrIP + ":" + aStrPort    End If               If Trim(strProxy) <> "" Then       inf.dwAccessType = INTERNET_OPEN_TYPE_PROXY       inf.lpszProxy = strProxy       inf.lpszProxyBypass = ""       Call InternetSetOption(0, INTERNET_OPTION_PROXY, inf, Len(inf))       Call InternetSetOption(0, INTERNET_OPTION_SETTINGS_CHANGED, "", 0)    Else       inf.dwAccessType = INTERNET_OPEN_TYPE_DIRECT       inf.lpszProxy = ""       inf.lpszProxyBypass = ""       Call InternetSetOption(0, INTERNET_OPTION_PROXY, inf, Len(inf))       Call InternetSetOption(0, INTERNET_OPTION_SETTINGS_CHANGED, "", 0)    End IfEnd Sub'===使用代理上网Private Sub Command1_Click()    SetProxy "123.10.10.233", "80", TrueEnd Sub     '===不使用代理上网Private Sub Command2_Click()    SetProxy "123.10.10.233", "80", FalseEnd Sub

这只是针对 hInternet 的吧

这个貌似是针对特定一次连接而设置的是否使用代理，并非是全局设置
[解决办法]
测试，注册表值没有修改。网上有讨论说要用api来修改注册表……
[解决办法]
设置代理：

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000001
"ProxyServer"="ip:端口"
[解决办法]
我也来试一试。。。
[解决办法]
测试过 没用 xp sp2
[解决办法]
设置注册表要重启机子的。

网上有个C写的，改完直接刷新的

你性测试什么问题按啊
