Question : Can't install wifi printer MX870

I have a wireless network that uses a vpn wireless router. I'm able to connect to the internet fine, however, when I setup the printer, the system doesn't see it.

The printer has an ip 192.xxx.xxx.20
The printer shows that I have connection to the wireless
The printer driver is installed correctly.
When I hookup the lan wire to my laptop I can print, when I unhook and try to print, the printer isn't available and the IP ping returns time out.
Firewall is turned off and disk permission has been repaired.

Not sure if this is a:
1- Printer problem (don't think so)
2- Network problem (logical)
3- Router problem (most logical)

Any help would be appreciate it.

Answer : Can't install wifi printer MX870

Is the email address the ONLY item in that memo field? I"m betting it's not, so you'd have to have some method to find that Email address in the Memo field, and AFAIK there is no builtin macro action that will do that - you'll need to use Regular Expressions, which can evaluate a text string/file and return to you a matched string, based on the "expression" you supply.

The code attached below will do this. Just copy/paste those items into a new Standard Module (name that module basTextFunctions, or something like that), and then use the FindEmailInString function to return the first Email address located in the string. To do that, assuming you have a Form on which the Memo field is present, you could include a button to show the value:

Sub MyButton_Click()
  Msgbox  FindEmailInString(Me.YourMemoField)
End Sub

Note the code for that Regular Expression came from John Nurick's excellent page here: http://www.j.nurick.dial.pipex.com/Code/index.htm

  'Takes a search string (Target) and a regular expression
  '(Pattern), and an optional Item argument.
  '- If Item is omitted and a substring of Target matches Pattern,
  '  returns that substring.
  '- If Pattern includes grouping parentheses, a substring of Target
  '  matches Pattern, and Item is an integer, returns the submatch
  '  specified by Item (first submatch is item 0). If there aren't
  '  enough submatches, returns Null. Negative values of Item start
  '  counting with the last submatch.
  '- If no match, returns Null.
