关于创建VPN时参数的问题
我在网上找到了这个 vb 6.0 写的 创建 VPN 连接的代码，我现在用这个代码可以成功创建 VPN连接，但是里面的参数不会设置。
我想取消 在远程连接上使用默认网关 ，但每次创建默认都是选中的，请问各位高手应该怎么做啊？
下面是我在网上找到的代码，代码是可以用的，请高手帮我看一下：

[解决办法]
楼主找到的代码不完整，缺少了下面这段。
一看就知道作者是那个喜欢YY的家伙。
Private Sub Command1_Click() Dim sEntryName As String, sUsername As String, sPassword As String sEntryName = "VPN" sUsername = "super" sPassword = "greenbean" If Create_PPPoE_Connection("VPN", sEntryName, sUsername, sPassword) Then MsgBox "连接建立成功！" Else MsgBox "连接建立失败！" End IfEnd Sub
