1) My feeling is B should be a service so that it is not dependent on a logged in user. The ASP activity from A may occur when there is no active login, correct?
2) A should not "wake up" B, but B should periodically poll the data. By the nature of your setup there is some latency for the "B" operation, meaning it is not as immediate as A doing the store. Therefore if the timer in the service fires every N Insert_Your_Favorite_Time_Units, then things should be fine.
3) As I think things should be set up, this question is moot.

My asp.net application A stores data in an SQL 2000 database. My application
B (on the same server but under a different userid - not ASPNET) reads these
data, does its job (big load, low priority) and updates the database. A does
not wait any answer nor acknowledgement from B.
Questions :
1) I think B can be a console application, am I right ?
2) How can A wake up B when A has stored data for B in the database ?
3) How can B wait when it has completed a task, until A wakes it up ?
Thank you,
Gilbert
