 Trick to returning datarows using WCF Minimize
Location: BlogsSean Cullinan    
Posted by: Sean Cullinan 8/12/2008 1:21 PM

As mentioned in other posts I'm working on using Peer Mesh for real time notification of my clients in my application.  When one client crud's a datarow I want to notify all the other clients of the change.  The easiest way is to send the datarow over the mesh. Not so fast, as I found.  You cannot send a datarow over the mesh because even though it seems like it should be inherently serializable, it is not.

Fortunately there is an easy solution.  Just flatten your datarow using the .itemarray function and send the array over the peermesh.  Mydr.itemarray is all you need.  On the receiving side you can simply declare a new datarow off of an existing table, then set myNewDR.itemarray = Mydr.itemarray, then add the row to your datatable.

That's it, I use this method extensively and it is working very well for me!

This arrangement, which came into effect in 2002, Air Jordan shoes provides for the manufacture and marketing of two Air Jordan 2010 -- NBA Master Link and NBA Denial. Both these Air Jordan 2011 carry the NBA logo on the tongue, sole, heel and sock liner.<br>http://www.usjordanshoesoutlet.com/<br>

It's all a matter of how much you're willing to spend. While most bowling [url=http://www.usjordanshoesoutlet.com/air-jordan-retro-10-c-29.html/]retro jordan 10[/url] are designed in a relatively formal style which most of us are familiar with, there are now plenty of bowling shoes which closely resemble conventional athletic [url=http://www.usjordanshoesoutlet.com/air-jordan-retro-11-c-30.html/]air jordan 11[/url] or [url=http://www.usjordanshoesoutlet.com/air-jordan-retro-12-c-31.html/]air jordan 12[/url].

<br><br><br>The 2010 regular season is the first year that the league will use a modified version of the scheduling formula that was first introduced in 2002, in which all teams will play each other at least once every four years, and will play in every other team's stadium at least once every eight years (notwithstanding the regular season games played overseas as part of the NFL International Series). Under the original 2002 formula, since the pairings were strictly based on alphabetical order, those teams scheduled to play all the AFC West clubs had to travel to both Oakland and San Diego in the same season, while those clubs playing the entire NFC West had to make their way to both San Francisco and Seattle.
