Owner Information with Option Strict On

[Jeff]

I'm trying to use the code posted in various forums to get the Owner Name on
a Pocket PC device, and I'm having a bit of trouble. Please help.
(I'm using VB.NET with Option Strict On.)

My code is:

I have a form with a button. The button click event has the following two
lines:

Dim test As String = OwnerName()
MessageBox.Show("[" & test & "]")

OwnerName is the following function:

Public Function OwnerName() As String

Try

Dim ownerbytes As Byte()
ownerbytes =
CType(OpenNETCF.Win32.Registry.CurrentUser.OpenSub Key("ControlPanel\Owner").
GetValue("Owner"), Byte())

OwnerName = System.Text.Encoding.Unicode.GetString(ownerbytes, 0,
72).TrimEnd(CType("\0", Char))
'Note: I've also tried the following line with the same result:
'OwnerName = System.Text.Encoding.Unicode.GetString(ownerbytes,
0,72).TrimEnd("0"c)

Catch nEx As NullReferenceException
MessageBox.Show("Please enter your Owner Name before using this program." &
CL & nEx.ToString & CL & nEx.Message)

Catch ex As Exception
MessageBox.Show(ex.ToString)

End Try

End Function

The Owner Name on the device is

Test Name

Stepping through the code, I typed the following into the Command Window
before the 'OwnerName=' assignment:
?System.Text.Encoding.Unicode.GetString(ownerbytes , 0,
72).TrimEnd(CType("\0", Char))
"Test Name"

I typed the following into the Command Window after the 'OwnerName='
assignment (note the trailing quote is gone from the result):
?ownername
"Test Name

When control returned to my button event, I got the same result with the
variable, test:
?test
"Test Name

And finally, the Messagebox displayed (Note no trailing ']'):
[Test Name

I'm trying to get test = "Test Name", and the Messagebox to show [Test Name]

What am I missing??

Thanks for your help.

OwnerName = System.Text.Encoding.Unicode.GetString(ownerbytes, 0,
72).TrimEnd(CType("\0", Char))
'Note: I've also tried the following line with the same result:
'OwnerName = System.Text.Encoding.Unicode.GetString(ownerbytes,
0,72).TrimEnd("0"c)

Try replacing

..TrimEnd(CType("\0", Char))

with

..TrimEnd(ChrW(0))
VB.NET doesn't support C style string escapes.
