本文 RasDialというＡＰＩ関数を使用すればプログラム上でダイヤルアップ接続ができるようです。 参考となるソース リストボックス(List1) '設定されている接続名が表示される テキストボックス(Text1) 'ユーザー名 テキストボックス(Text2) 'パスワード コマンドボタン(Command1) '接続 が必要らしいですね。 で、これを実行するとリストボックスに設定されている接続名がリストアップ されますので、該当する接続名を選択して、 テキストボックス(Text1)に、ユーザー名 テキストボックス(Text2)に、パスワード を入力して コマンドボタン(Command1)を押すとダイヤルアップ接続を行う という流れらしいです。 ですので、自動的に接続したい場合は、プログラム内で接続名、ユーザー名、パスワードを設定して実行すればいいのではないでしょうか？ Option Explicit Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (pDst As Any, ByVal pSrc As String, ByVal ByteLen As Long) Private Declare Sub ZeroMemory Lib "kernel32.dll" Alias "RtlZeroMemory" (Destination As Any, ByVal Length As Long) Const RAS95_MaxEntryName = 256 Const RAS_MaxPhoneNumber = 128 Const RAS_MaxCallbackNumber = RAS_MaxPhoneNumber Const UNLEN = 256 Const PWLEN = 256 Const DNLEN = 12 Private Type RASDIALPARAMS dwSize As Long ' 1052 szEntryName(RAS95_MaxEntryName) As Byte szPhoneNumber(RAS_MaxPhoneNumber) As Byte szCallbackNumber(RAS_MaxCallbackNumber) As Byte szUserName(UNLEN) As Byte szPassword(PWLEN) As Byte szDomain(DNLEN) As Byte End Type Private Type RASENTRYNAME95 'set dwsize to 264 dwSize As Long szEntryName(RAS95_MaxEntryName) As Byte End Type Private Declare Function RasDial Lib "rasapi32.dll" Alias "RasDialA" (ByVal lprasdialextensions As Long, ByVal lpcstr As String, ByRef lprasdialparamsa As RASDIALPARAMS, ByVal dword As Long, lpvoid As Any, ByRef lphrasconn As Long) As Long Private Declare Function RasEnumEntries Lib "rasapi32.dll" Alias "RasEnumEntriesA" (ByVal reserved As String, ByVal lpszPhonebook As String, lprasentryname As Any, lpcb As Long, lpcEntries As Long) As Long Private Declare Function RasGetEntryDialParams Lib "rasapi32.dll" Alias "RasGetEntryDialParamsA" (ByVal lpcstr As String, ByRef lprasdialparamsa As RASDIALPARAMS, ByRef lpbool As Long) As Long Private Function Dial(ByVal Connection As String, ByVal UserName As String, ByVal Password As String) As Boolean Dim rp As RASDIALPARAMS, h As Long, resp As Long rp.dwSize = Len(rp) + 6 ChangeBytes Connection, rp.szEntryName ChangeBytes "", rp.szPhoneNumber 'Phone number stored for the connection ChangeBytes "*", rp.szCallbackNumber 'Callback number stored for the connection ChangeBytes UserName, rp.szUserName ChangeBytes Password, rp.szPassword ChangeBytes "*", rp.szDomain 'Domain stored for the connection 'Dial resp = RasDial(ByVal 0, ByVal 0, rp, 0, ByVal 0, h) 'AddressOf RasDialFunc Dial = (resp = 0) End Function Private Function ChangeToStringUni(Bytes() As Byte) As String 'Changes an byte array to a Visual Basic unicode string Dim temp As String temp = StrConv(Bytes, vbUnicode) ChangeToStringUni = Left(temp, InStr(temp, Chr(0)) - 1) End Function Private Function ChangeBytes(ByVal str As String, Bytes() As Byte) As Boolean 'Changes a Visual Basic unicode string to an byte array 'Returns True if it truncates str Dim lenBs As Long 'length of the byte array Dim lenStr As Long 'length of the string lenBs = UBound(Bytes) - LBound(Bytes) lenStr = LenB(StrConv(str, vbFromUnicode)) If lenBs > lenStr Then CopyMemory Bytes(0), str, lenStr ZeroMemory Bytes(lenStr), lenBs - lenStr ElseIf lenBs = lenStr Then CopyMemory Bytes(0), str, lenStr Else CopyMemory Bytes(0), str, lenBs 'Queda truncado ChangeBytes = True End If End Function Private Sub Command1_Click() Dial List1.Text, Text1, Text2 End Sub Private Sub List1_Click() Dim rdp As RASDIALPARAMS, t As Long rdp.dwSize = Len(rdp) + 6 ChangeBytes List1.Text, rdp.szEntryName 'Get User name and password for the connection t = RasGetEntryDialParams(List1.Text, rdp, 0) If t = 0 Then Text1 = ChangeToStringUni(rdp.szUserName) Text2 = ChangeToStringUni(rdp.szPassword) End If End Sub Private Sub Form_Load() 'example created by Daniel Kaufmann (daniel@i.com.uy) 'load the connections Text2.PasswordChar = "*" Command1.Caption = "Dial" Dim s As Long, l As Long, ln As Long, a$ ReDim r(255) As RASENTRYNAME95 r(0).dwSize = 264 s = 256 * r(0).dwSize l = RasEnumEntries(vbNullString, vbNullString, r(0), s, ln) For l = 0 To ln - 1 a$ = StrConv(r(l).szEntryName(), vbUnicode) List1.AddItem Left$(a$, InStr(a$, Chr$(0)) - 1) Next If List1.ListCount > 0 Then List1.ListIndex = 0 List1_Click End If End Sub
