Dialer question

Please accept my apologises if I have posted in the wrong newsgroup. My
problem relates to the Phone Dialer. I had been having difficulty
activating the WindowsXP Phone Dialer via code I run using Microsoft Excel.
The idea is that when a cell containing a phone number is selected and a
macro is run the Phone Dialer will activate, transfer the number from the
cell and then the number would be dialled. This is how it works on another
computer using WindowsME. Because I could not get it to work in WindowsXP I
copied the Dialer files from WindwsME to XP the Dialer now almost works. I
say almost works because the code which transfers the cell content to the
dialer does not function.

' Transfer cell contents to Dialer
Application.SendKeys "%n" & CellContents, True

Anyone had a similar experience, or know what I should do. It beats me why
Microsoft has tampered with this very useful feature.
