Writing to Registry: Unauthorized Access Exception

[pagates]

Hi All,

I am attempting to write values to the registry, but get an
UnauthorizedAcc essException when I try to do a SetValue on an existing key.
However, I can create the key, with a value, when it does not exist.

Here is a snippet of the code:
Dim RegKey As RegistryKey
RegKey = Registry.LocalM achine.OpenSubK ey(BaseKey & "\" &
SubKey, False)
If (RegKey Is Nothing) Then
RegKey = Registry.LocalM achine.CreateSu bKey(BaseKey &
"\" & SubKey)
End If
Try
RegKey.SetValue ("NumberRuns ",
Tasks(I).Number Runs.ToString() )
RegKey.SetValue ("TotalSeconds" ,
Tasks(I).TotalS econds.ToString ())
Catch ex As Exception
MessageBox.Show ("Exception: " & ex.Message)
Finally
RegKey.Close()
End Try

What do I need to do to be able to update this key?

Thanks,
pagates

Hello Pegates,
How are you doing?

The error that you have specified could be due to lack of rights on the
machine. Try checking the rights of the user.

Also the OpenSubKey method has an overload that provides write access. Try
passing true to it, instead of False as you are doing:
RegKey = Registry.LocalM achine.OpenSubK ey(BaseKey & "\" & SubKey,
False) ----- try passing True instead of False

I hope this helps.

Thanks
Mona

Hi Mona,

It was that stupid parameter...D'o h! (Yes, blame the parameter, not the
programmer) : )

Thanks again,

Well, what is the programmer to do when the parameters forget to set
themselves?? :)
