Nah Sekarang admin akan kasih Tutorial cara membuat cek koneksi internet lewat Visual Basic.. Ok langsung saja simak baik - baik :
1. Buatlah 1 form dan 1 module
2. Buat 1 button di form1, lalu isi dengan kode :
Private Sub Command1_Click()
If CekKonek = True Then
MsgBox "Computer terkoneksi ke Internet", vbInformation 'Jika Tersambung
Else
MsgBox "Computer tidak terkoneksi ke Internet", vbExclamation 'Jika tidak tersambung
End If
End Sub
3. Jika sudah kita langsung ke module, lalu isi dengan kode begini:
Public Declare Function RasEnumConnections Lib "RasApi32.dll" Alias "RasEnumConnectionsA" (lpRasCon As Any, lpcb As Long, lpcConnections As Long) As Long
Public Declare Function RasGetConnectStatus Lib "RasApi32.dll" Alias "RasGetConnectStatusA" (ByVal hRasCon As Long, lpStatus As Any) As Long
'
Public Const RAS95_MaxEntryName = 256
Public Const RAS95_MaxDeviceType = 16
Public Const RAS95_MaxDeviceName = 32
'
Public Type RASCONN95
dwSize As Long
hRasCon As Long
szEntryName(RAS95_MaxEntryName) As Byte
szDeviceType(RAS95_MaxDeviceType) As Byte
szDeviceName(RAS95_MaxDeviceName) As Byte
End Type
'
Public Type RASCONNSTATUS95
dwSize As Long
RasConnState As Long
dwError As Long
szDeviceType(RAS95_MaxDeviceType) As Byte
szDeviceName(RAS95_MaxDeviceName) As Byte
End Type
Public Function Cekkonek() 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)
If RetVal <> 0 Then
MsgBox "ERROR"
Exit Function
End If
Tstatus.dwSize = 160
RetVal = RasGetConnectStatus(TRasCon(0).hRasCon, Tstatus)
If Tstatus.RasConnState = &H2000 Then
Cekkonek = True
Else
Cekkonek = False
End If
End Function
4. Lalu save jika mau di simpen, jika sudah tinggal di run.
