visual basic errors from MS sample

Hi,

It's been quite a while since I worked with Visual Basic, and so I'm running into errors just trying to build a simple MS application using these instructions:  http://support.microsoft.com/kb/74861
I created the project as a Windows Forms Application.

Sub Form_Load ()
      'This procedure will start the VB source application.
      z% = Shell("SOURCE", 1)
      z% = DoEvents()   'Causes Windows to finish processing Shell command.
      Text1.LinkMode = NONE   'Clears DDE link if it already exists.
      Text1.LinkTopic = "Source|Form1"   'Sets up link with VB source.
      Text1.LinkItem = "Text1"           'Set link to text box on source.
      Text1.LinkMode = MANUAL            'Establish a manual DDE link.
      ManualLink.Value = TRUE            'Sets appropriate option button.
   End Sub

Select allOpen in new window

Other than my form being called Form1, I didn't change anything. However, I already get these errors:

Error	1	'z' is not declared. It may be inaccessible due to its protection level.	D:\Development\VB\MyDDE-VBtest\MyDDE-VBtest\Form1.vb	16	9	MyDDE-VBtest

Can anyone tell me what's going on here?  Is there a secret to building sample code from MS?  Unfortunately the article doesn't say anything about any additional references or libraries or anything that I need to add.

How do I fix this?

Thanks!

P.S. I'm using Visual Studio 2010 on Win 7. I have admin privileges.
