    One more update...

    Paul and I are in an active conversation about the plugin and I've got a new-new test app from him to try out.

    More when he/I/we know more!

    Hang in there, Paul got a bit closer to figuring out what's up on Friday.

    Sorry all for my unresponsiveness.
    I had no idea this thread was still alive (I must have missed the notification email that this thread has been contributed to).

    I did a Google search trying to debug some issues w/ XPort and came across this thread...and to my surprise it is still alive!

    Sorry to keep y'all waitin.
    I have been bangin my head against the wall trying to figure this one out.

    stang: Are you using XPort too?

    I have rewritten *all* of the COM port GPS code w/ a 100% C# library; my C++ gpscom.dll code is a thing of the past.
    Even after the rewrite I still get a "The request is not supported" error when I try to open a XPort COM port.
    I guess I am going to have to write a small native C++ test app to learn how to properly open an XPort port.

    Again, sorry for the delay.
    My Car's CFMapPoint ain't workin either, so I am feeling the same pain as you.
    My problem is a bit different though; I am not using XPort...and worst of all it *used* to work!
    Without changing anything in CFMapPoint itself, my CFMapPoint just stopped working correctly, no more GPS or Routes or anything.
    The only change I made were some Windows Updates, so again I am blaming them!

    Please be patient; I am workin on it.
    Hopefully the fact that I wrote CFMapPoint in the first place will show you how much I want this to work.
    Alas, I am only one person and I have a life outside of CFMapPoint so sometimes it is hard to find the time.
    The source code is available for anyone else that wants to pitch in.

    The best thing someone could do would be to write a "hello world" C++ app that can open an XPort port and read from it for a few seconds.
    I know how to do this for standard ports, but the XPort ports are causing me a headache for some reason.
    (I assumed they would accept the same standard COM port code...they currently don't appear to).

    Have you tried PMing "Curiosity," the author of XPort?

    I emailed him last week and have received no response.
    Maybe he's out of town...or busy like me!

    OK folks, I think I figured it out!
    Sometimes writing good thorough code makes things break!
    The problem was that I was calling "GetCommProperties" on the port to find out if its properties are within acceptable contraints (baud rate, rx queue, etc).
    The GetCommProperties on an XPort fails.
    I commented out that call and everything seems to work fine now!

    Please give my v0.6 test app a try at the "Releases" page of:
    http://workspaces.gotdotnet.com/CFMapPoint

    Please let me know if it:
    1) finds your COM port
    2) can open your COM port
    3) can read GPS info from your COM port

    If all looks good I will add this code to CFMapPoint hopefully this weekend.

    No way is it "ship" quality!
    I fixed quite a few MTTF issues today and release a v0.7 test app.
    Give that a try and let it run long-haul.
    Try to open and close the ports multiple times and just generally stress the app.
    I know of a few more issues when dealing w/ edge cases link non-existing or non-GPS ports, so don't worry *too* much about that.

    Otherwise, I hope to throw this code in to CFMapPoint and release v0.8 within a week.
