    I'm using code like this by VB6 and it works perfect but not by VB.NET. Why?


    Option Explicit
      Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
      Private Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long
      Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByVal lpValue As String, ByVal cbData As Long) As Long
       
    Private Sub Command1Click()
       Const REG    SZ As Long = 1
       Const HKEYLOCALMACHINE = &H80000002
       Const KEYSETVALUE = &H2
       Dim sKeyName As String
       Dim lRetVal As Long
       Dim hregKey As Long
       sKeyName = "SOFTWARE\Wiesemann & Theis\Com-server\Com2"
       
           lRetVal = RegOpenKeyEx(HKEYLOCALMACHINE, sKeyName, 0, KEYSETVALUE, hregKey)
           
       Dim lValueType As Long
       Dim vValueSetting As String
       Dim sValueName As String
       
           sValueName = "IpAddress"
           lValueType = REG_SZ
           vValueSetting = "123.45.67.89" & Chr$(0)
           lRetVal = RegSetValueEx(hregKey, sValueName, 0, lValueType, vValueSetting, Len(vValueSetting))
           RegCloseKey (hregKey)
    End Sub

    You no longer need to use API to access the registry in VB.NET. Instead, take a look at the Microsoft.Win32 namespace, which contains Registry functions. For example,


    RegistryKey myKey = Registry.LocalMachine.OpenSubKey("Software\MySoftware");
    MessageBox.Show (webZincKey.GetValue("Serial").ToString());


    displays a message box displaying the value of the Serial item in the HKEYLOCALMACHINE\Software\MySoftware key.
