Checking for a registry value...

[Guest]

How can I lookup registry values?

I'd like to check for the existence of this folder in the registry:
HKLM\Software\AcmeCompany\MWIApplications\AutoLogonForSharedWorkstations

so that I can use a login prompt for only these machines.

Has anyone ever done this?

It's possible to work with the Windows registry using the
Microsoft.Win32.Registry class, and other related classes from the same
namespace.

Here is some old old vb.net code I dug up.
Notice the imports and the bad hungarian notation.




Imports Microsoft.Win32

Public Class RegReader


Public Shared Function ReadRegValue(ByVal strKeyName As String) As
String

Dim regVersion As RegistryKey
Dim keyValue As String

keyValue = "SOFTWARE\\MySubThingLikeMicrosoft"
regVersion = Registry.LocalMachine.OpenSubKey(keyValue, False)
Dim strRegistryValue As String
strRegistryValue = string.Empty
If (Not regVersion Is Nothing) Then
strRegistryValue = regVersion.GetValue(strKeyName, "")
regVersion.Close()
End If

return strRegistryValue

End Function



End Class

This is very helpful - will this bring up any 'Security' errors if the
machine that my application runs this code on doesn't have admin rights?

This is nice... but can you expland on this and tell how I would be able to check the value of a key? Say the Key was HKLM\software\......\ibm\effected and I wanted to see if the value was "YES" I then want to be able to create a text file. Is this possible? Well i know it is but can someone shed some light?
