Filter delete rows on subscriber
matches the filter? I need this to decide if I want to add a new table into
replication.
TIA.
Rajesh
There is a table with a large number of rows (5-6 million), with only a few
rows (2000-3000) replicated to each client. Each client needs to get a
different set of rows.
I want to know whether:
1. The filter is applied on the subscriber to delete the rows?
2. Or the IDs to be deleted is sent to the subscriber by the publisher?
3. Or the IDs on the subscriber is sent to the publisher, for which the
publisher responds with the IDs that should no longer be available in the
subscriber.
Due to the large number of rows, I'm just worried that #2 and #3 will lead
to a lot of inefficeincy. And if that is the case, I would rather sync this
data outside of replication.

File Transfer from deskop to PDA thro TCP\IP
Hi All,
I am trying to pass a text file from desktop machine to PDA thro TCP-IP protocols. It follows Server (on desktop machine) and Client (on pda) architecture. File is converted to bytes and will be pushed to network stream. The client on PDA will receive the bytes and store it on queue and writes the file on PDA. The operation is accomplished through threads on both Server and client. Applications are developed on MS Visual Studio 2005 (C#).
For large files like 1024 KB or having lines about 15000, it takes around 15 minutes. Can anyone give a better idea to transmit files from desktop machine to PDA using TCP-IP protocols.
Thanks in advance

Maybe using compression would help?|||Hi Erik,
Is it possible to provide more details or links regarding Compression techniques that can be implemented on PDA applications?
Thanks in advance,
Boss
