Perhaps someone can point me in the right direction in finding code, or
finding reading information on how to pass information (ie. ArrayList,
string, etc) between two running window applications, that won't
neccessarily be on the same machine.
This will be my first attempt at this, and I'm not sure if this falls under
COM, or ActiveX.
Any and all help is appreciated.
Thanks in advance.

Hi Willy,
its been a long time when i used shared memory. I am sure
this is also a very fas way to communicate. I am not a friend
of hidden windows, so i even dont mentioned that. I cant
remember how fast it was compared to WM_COPYDATA.
Regards
Kerem

Kerem,
While Sendmessage/WM_COPYDATA is really fast when it comes to small messages
(max. 2Kb), shared memory is a clear winner when you have to deal with
somewhat larger data messages (>8Kb ).
Using WCF (NetNamedPipeBi nding ) in a service application I was able to pass
data structures of 8Kb at a rate of ~70Mb/sec. The highest rate I measured
using WM_COPYDATA was ~55Mb/sec using 2Kb messages.
Note that whether you like hidden windows or not, Sendmessage/WM_COPYDATA
needs a window to send your message at, in a Windows Service (or Console
application) there is no other option, after all that's what COM uses under
the covers too.
Willy.

Hi,
In my application I get lots of different sorts of information from
databases. As such, a lot of information is stored in DataSets and DataTable
objects.
Up until now, I have been passing around chunks of data in
DataTables/DataSets, simply because that was the format that they were in
when the data was taken from the database. Now, I know this maybe a pretty
silly question with a standard "it depends" answer, but I'm going to...
