Dear all,

I am writing the socket programming.
The server part has been done in c sharp vs2005. The server will push some
data to the client every second.
How can the excel be done so that excel can show the information from server
and refresh every second??

I plan to use c sharp dll function. But how can make the excel refresh every
seconds by dll which has information alert to excel to show???
