How to get notified in PPC application when PPC is sync'd

I have a Pocket PC application (C#, .NET on Mobile 5) and I need to determine
either: 1) when the Pocket PC is connected with the host PC through
ActiveSync, or 2) when one or more files are deleted from a Pocket PC
directory - these are deleted by a host PC application using RAPI. Is there a
way for my PPC to get either notification?

For info on how a _desktop_ application can determine when an
ActiveSync connection is made, use google
(http://groups.google.com/advanced_group_search) to look up
cerapiinit registry
in this newsgroup. You can use that info to write an app that uses
RAPI to notify and/or start a Pocket PC app.

See a current thread called "File transfers between PC <> PocketPC" in
this newsgroup.

Ichecked the references you mentioned in your reply. Still one question
though - do I need to initiate some action on the PPC, let's say to start a
timer, etc to check for a file? Or can RAPI make an IPC call into a running
application? Either way if I have a running PPC application is there a way to
notify that application that the files have been deleted by a desktop app? It
wasn't clear to me from what I read.

Hello my friend.

You can do the 2 things really. You can use the
OpenNetCF.Desktop.Communication. Download the .dll from the site:
http://www.opennetcf.com/SharedSource/DesktopCommunication/tabid/90/Default.aspx

Import it and do something like this:

using OpenNETCF.Desktop.Communication;

class Rapi
{
private RAPI rapi = new RAPI();

public Rapi()
{
rapi.Connect();
}

public bool isConnected()
{
return rapi.Connected;
}
}

Check this out.
http://www.opennetcf.com/library/communication/OpenNETCF.Desktop.Communication.RAPIMembers.html

Hope it helps.
Peace friend.

I've definitely not used RPC. Sure, the PPC app could poll for file
deletion (loop that checks for existence and then pauses).

I've set up all my apps so they only allow one copy to run and accept
command-line arguments. If another copy runs, it looks for the first,
brings the first to the foreground, sends the command line as a
special message to the first copy, and then exits. So you could use
CeRapiInvoke to "start" your PPC app and send itself a message.

What method do you use to send a message from one instance of the app to
another?

The SendMessage function and WM_COPYDATA.

You can determine if a device has synchronized with active sync using the
following C# code:

Wire up the active synce state changed event and then perform the action
needed

SystemState activeSyncState = new
SystemState(SystemProperty.ActiveSyncStatus);
activeSyncState.Changed += new
ChangeEventHandler(activeSyncState_Changed);

void activeSyncState_Changed(object sender, ChangeEventArgs args)
{
ActiveSyncStatus status = (ActiveSyncStatus)args.NewValue;

try
{
if (status == ActiveSyncStatus.Synchronizing)
{
// Do Some work
}
}
catch (Exception ex)
{
// Handle Exception
}
}

2. Determine if a directory changes:

Rick,

Thanks for the help, it worked great. The only change I had to make was to
declare activeSyncState at the class level and not locally. But it's
working. This helps me a great deal. Thanks again.
