MSMQ on PPC 2003 Installation

[Steve B.]

Hi,

I want to test MSMQ capabilities on a PPC 2003 device.
I use VS 2005 Final with CF 2.0 to build a simple app.

When I launch the application, I get an error telling me that MSMQ is not
installed on my device.

After some search, I've seen that I need to install a redistribuable package
to have MSMQ on the device.
I can't find this package, where it is?
An article told it is in Program files\Microsoft Visual Studio 8\Smart
Device\SDK\SDKredist... but this folder does not exists, and in VS 2005
setup
I did a full installation....

Thanks for any help

Steve

You can find it in the PPC 2003 SDK under Support\Msmq.

There are some specific steps needed to install and register MSMQ once you
have installed the required files. Can I suggest this series of posts from
Mark Ihimoyan as these contain lots of detail on System.Messaging in .NETCF
2 and installation issues:-

Are you planning on using MSMQ in combination with the ActiveSync
desktop-passthrough?

Message will mostly be transported over GPRS connection.
But, if user is at office, sending message over Active Sync (cradle or
bluetooth) or wifi should be great...

Well you should be aware of the fact that the desktop passtrough (for
non Mobile 5 devices) isn't robust enough to use it in combination with
MSMQ.
Desktop passthrough can't provide the required stability.

What can happen ?
If a message transfer fails, the user will have to un craddle then craddle
again, don't he ? No message will be "lost".

Actually, 95% of transfers will occurs out of office, so using GPRS, and
then, can't be sure that the connection will remain stable.

Do you think MSMQ is not a good solution for our application ?
It is a typical ordering application, with a local db (sql mobile probably),
the user types orders and send them in a queue. Once a day the user
"synchronize", so actually send new orders, and get client db modifications...

Hi Steve,
Just a quick note about MSMQ and Activesync (Version 3.8 at least). Because
the activesync uses a private IP address it is not possible for it to be
routed accross a network in the usual manner. Outgoing is fine but the return
path will fail as MSMQ operates is a discnnected as opposed to connected
format (ie it does not establish a TCP/IP Tunnel and then send and recieve
it's data, it connects, sends data and then disconnects). If you MQ target q
is on another device other than the workstation directly connected to the
device it is unlikly that 2 way comms will be established as a result ACK
messages cannot be returned to the transmitting device etc.

We have used activesync to provide a reliable transport mechanism using a
local MQ managers on machines that dock handheld devices and it is
(Reasonably) fast and very reliable. Activesync n our case simply acts an
endpoint that allows the device to establish and maintain a connection to the
workstation.

To get to this point we had to use a Serial dock and a local PC RAS
connection in order to establish a "Real" network link.
