[Resolved] reading reg values

[peteoc]

I'm attempting to write an application which reads all sub keys from

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\

I am managing to retrieve all the subkey names fine, however when I want to retrieve a value from within this I get nothing.

My code is as follows:

Dim regkey As RegistryKey
        regkey = Registry.LocalMachine.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Uninstall\", True)
        Dim key As String
        Dim test As String
        For Each key In regkey.GetSubKeyNames()
            test = CType(regkey.GetValue(key & "\InstallDate"), String)
            TextBox2.Text = TextBox2.Text & vbCrLf & key & " - '" & test & "'"
        Next

I've only tried the CType bit as I read that you need to convert a registry value to string to be able to read it.

A result is as follows

CNXT_MODEM_HDAUDIO_VEN_14F1&DEV_2BFA&SUBSYS_14F100C3 - ''
Combined Community Codec Pack_is1 - ''
Connection Manager - ''
DirectAnimation - ''
DirectDrawEx - ''
DXM_Runtime - ''

some of these obviously dont have a value for InstallDate however I know for sure that the Combined Community Codec Pack_is1 has a value for this.

Any help is gratefully appreciated.
