用vb实现ADSL拨号

VB6.0代码


1、第一个问题还要添上连接名（就是拨号连接的名字）
我这里有一个现成的代码，挺长的，能上网、断网、查看网络状态、查看连接数目，如果其它的不需要的话，自己看函数的名字，删了即可
把一下代码粘贴到模块中，在窗体某控件的时间中写：
Dim recAdConn&
recAdConn = AddConnection("连接名", "", "", "用户名", "密码", "")
Public Type RASCONN95
dwSize As Long
hRasConn As Long
szEntryName(256) As Byte
szDeviceType(16) As Byte
szDeviceName(128) As Byte
End Type
Public Type RASCONNSTATUS95
dwSize As Long
RasConnState As Long
dwError As Long
szDeviceType(16) As Byte
szDeviceName(128) As Byte
End Type
Public Declare Function RasGetConnectStatus Lib "RasApi32.DLL" Alias "RasGetConnectStatusA" (ByVal hRasCon As Long, lpStatus As Any) As Long
Public Declare Function lstrcpy Lib "kernel32" Alias "lstrcpyA" (lpString1 As Any, ByVal lpString2 As String) As Long
Public Declare Function RasDial Lib "RasApi32.DLL" Alias "RasDialA" (lpRasDialExtensions As Any, ByVal lpszPhonebook As String, lprasdialparams As Any, ByVal dwNotifierType As Long, lpvNotifier As Long, lphRasConn As Long) As Long
Public Declare Function RasHangUp Lib "RasApi32.DLL" Alias "RasHangUpA" (ByVal hRasConn As Long) As Long
Public Declare Function RasEnumConnections Lib "RasApi32.DLL" Alias "RasEnumConnectionsA" (lprasconn As Any, lpcb As Long, lpcConnections As Long) As Long

Public Function AddConnection(strNewEntryName As String, strNewPhoneNumber As String, strNewCallbackNumber As String, strNewUsername As String, strNewPassword As String, strNewDomain As String) As Long
Const APINULL = 0&
Dim lngRetCode As Long
Dim lngRetLstrcpy As Long
Dim lngRetHangUp As Long
Dim lprasdialparams As RASDIALPARAMS95
On Error GoTo 10
lprasdialparams.dwSize = 1052
lngRetLstrcpy = lstrcpy(lprasdialparams.szEntryName(0), strNewEntryName)
lngRetLstrcpy = lstrcpy(lprasdialparams.szPhoneNumber(0), strNewPhoneNumber)
lngRetLstrcpy = lstrcpy(lprasdialparams.szCallbackNumber(0), strNewCallbackNumber)
lngRetLstrcpy = lstrcpy(lprasdialparams.szUserName(0), strNewUsername)
lngRetLstrcpy = lstrcpy(lprasdialparams.szPassword(0), strNewPassword)
lngRetLstrcpy = lstrcpy(lprasdialparams.szDomain(0), strNewDomain)
Screen.MousePointer = vbHourglass
hRasConn = 0
lngRetCode = RasDial(ByVal APINULL, vbNullString, lprasdialparams, APINULL, ByVal APINULL, hRasConn)
Screen.MousePointer = vbDefault
If lngRetCode Then
lngRetHangUp = RasHangUp(hRasConn)
End If
10
AddConnection = lngRetCode
End Function

Public Function GetConnections() As Long
Dim lngRetCode As Long
Dim lpcb As Long
Dim lpcConnections As Long
Dim intArraySize As Long

ReDim lprasconn95(intArraySize) As RASCONN95
lprasconn95(0).dwSize = 412
lpcb = 256 * lprasconn95(0).dwSize
lngRetCode = RasEnumConnections(lprasconn95(0), lpcb, lpcConnections)
GetConnections = lpcConnections
End Function

Public Function HangUpAll() As Boolean
Dim lngRetCode As Long
Dim lpcb As Long
Dim lpcConnections As Long
Dim intArraySize As Long
Dim intLooper As Long

ReDim lprasconn95(intArraySize) As RASCONN95
lprasconn95(0).dwSize = 412
lpcb = 256 * lprasconn95(0).dwSize
lngRetCode = RasEnumConnections(lprasconn95(0), lpcb, lpcConnections)

If lngRetCode = 0 Then
If lpcConnections > 0 Then
For intLooper = 0 To lpcConnections - 1
RasHangUp lprasconn95(intLooper).hRasConn
Next intLooper
Else
HangUpAll = False
Exit Function
End If
End If
HangUpAll = True
End Function
Public Function IsConnected() As Boolean
Dim TRasCon(255) As RASCONN95
Dim lg As Long
Dim lpcon As Long
Dim RetVal As Long
Dim Tstatus As RASCONNSTATUS95
TRasCon(0).dwSize = 412
lg = 256 * TRasCon(0).dwSize
RetVal = RasEnumConnections(TRasCon(0), lg, lpcon)
Tstatus.dwSize = 160
RetVal = RasGetConnectStatus(TRasCon(0).hRasConn, Tstatus)
IsConnected = IIf(Tstatus.RasConnState = &H2000, True, False)
End Function

2、查看当前IP
没有现成的代码，网上应该有的是吧！自己查一查
http://www.baidu.com/s?wd=VB+%B2%E9%BF%B4%B5%B1%C7%B0IP&cl=3

3、断网：第一个问题中已经说了，调用：
在控件事件中写
HangUpAll
完事
