PC<->PPC application comms concurrently with GPRS conn

Hi,
I am trying to develop an application with both PC and Pocket PC components.
The PC and PPC need to exchange data whilst the PPC (eg XDA) has an active GPRS connection.
I first tried using evc and RAPI to allow the PC and PPC components to talk to each other. However RAPI relies on ActiveSync and it seems you cant have an ActiveSync connection to the PC (eg over USB) at the same time as a GPRS connection.
So
1)Am I right that ActiveSync at same time as GPRS is impossible? (And hence RAPI...)
2)What is the easiest way to do PC<->PPC comms without ActiveSync, on the widest variety of PPC devices?
3)Is there a way to do this without writing PC and PPC sides for all of
i) Bluetooth
ii) USB
iii) Serial
It seems like a lot of hardwork to reimplement all these, but some models have BT, some only USB etc etc
Any help appreciated...
Regards,
Giles.

hey,
im also trying to write some client -> server software for my mda/pc. Ive managed to narrow it down to two technologies (excluding activesync cos it needs to be portable)
- Web Services
- Client Server Model (tcpclient and tcplistener)
webservices are good as they will run on any net connection with port80 open, pretty fast and versetile but have some bad flaws. u need some back end data store (like a mysql database) as data is not persistant on then... also u cannot "push" from the server to the device (this may or may not be an issue)
the tcpclient model is starting to appeal to me in a number of ways. u can define your own light-weight protol (SOAP has a nasty habbit of bulking the objects out and GPRS costs!)... i started to write some little test apps and so far its looking good. Ive wrote a very tiny server that runs on windows and has a thin client running a threaded tcplistener and a mysql backend datastore. The test mobie simply constructs a tcpclient object and writes a string "hello world" to the port, which the server picks up and displays in a messagebox... so far this concept is working really well, and i have more control over the serialisation and communication of the objects and types.
i hope ive helped u in some way hehe

Setting up VNC or Remote Desktop

I've set up LogMeIn, but it's left me dissatisfied. I don't like the fact that it's website based, and it's a little slow for my tastes.
I've attempted VNC and Remote Desktop but, sadly, it's a little over my head. I'm by no means a noobie, but I've never dabbled in remote desktop type work before.
Is there a simple tutorial for setting up VNC or Remote Desktop clients for the Wizard? I could really use one. I've been trying to search for it for a few days, and I turned up absolute zilch.
Thanks!

both VNC and remote desktop would need to be enabled on your workstation / server / computer and make sure that either the required ports for VNC (port 5900+) and Remote Desktop Connection (port 3389) and open your firewall or the windows firewall is turned off.
if you are trying to use VNC / RDP, using your GPRS/EDGE connection then there's more tweaking which needs to be done ... this would entail you to go to your router/firewall and open ports 5900 (VNC) and 3389 (Terminal Services / Remote Desktop Connection) and point these ports to the right IP Address (which would be the IP address of your workstation).
if you have any questions about remote access just email me back ... i use my XDA Exec, Qtek 8500 and all the other PDA's i have to access my network at the office as well as at my clients all the time ... both through VNC and through Remote Desktop Connection ....

what program do you need on the wizard to do remote desktop?
right now i can remote desktop to my work computer from my laptop at home. is it similar? thank you.

There should be a remote desktop client already installed on your Wizard. Look in the Programs folder for "Terminal Services Client". It works pretty much the same as it does on big Windows.

As dumb as this is, I really need a step by step to help me out on this subject.
I'm unsure what is needed to get the Remote Desktop Client working. I have XP Pro. I have a "Remote" section under my home computers system properties. However, the one tutorial I could find asked me to go into Add/Remove Windows Devices and apply some sort of setting there. Upon doing so, I was asked to insert my Windows XP CD which . . . I don't have.
If I don't need that CD, I am open to doing either Remote Desktop or VNC. Whichever is preferable, I guess. I don't know which is more full-featured, which one is quicker, etc.
So I need help getting started. What do I do?

Hey Dr.Other
Okay here is a step by step to enable remote desktop on your computer ( much better then VNC in my book but I am sure others may disagree..so in the end its personal prefrence...I just like RD (remote desktop) better cause I can stream music if I wanted and its also encrypted (I think I read that some where) any way here it is for remote desktop.
Guessing you are useing Windows XP Pro
Right Click on MY COMPUTER ( on your desktop)
From the menu that opens up Click (Left click) on PROPERTIES
You will see a few tabs in a window called System Properties
Click on the REMOTEtab
Check the Box under the Remote desktop area that say ALL USEERS TO CONNECT REMOTELY TO THIS COMPUTER (its not in caps)
Next click on Select Remote User and click ADD
TYpe in the users name (what ever name you use to login with)
Hit Okay till your back to your desktop
Phone:
Start\Programs\Terminal services Client
under servers type in the IP address of your computer ( Hint try it locally 1st if you have wifi in your house and then click connect) its a bit difficult to naviagate and the colors are not the best ( which leads me toa question ...look at the bottem for the Q ) but it will do...I have hcked email looked at my fav places for a book name I had bookmarked but forgot etc. its really cumbersome but in teh end it may get the job done. Though Fair warning your icons and stuff will be bunched up on your desktop computer once you RD from your Phone
RD to your phone..... What ? can you remote desktop to your phone ?
I think so...if you enable terminal service port on the device you maybe able to connect to it from your computer ...but I am still trying to figure that one out
Question for every one: IS it possible to get better colors when connecting to your home computer via terminal services on your phone ? ...they look like 256 colors (eww)

Even if you could it would slow the process down so much it wouldnt be worth it. I wouldnt even have a background on as it slows to a crawl.

vpn compatible apps

the remote desktop client on my vario ii connects to my work desktop perfectly using our office vpn but it is rubbish! the screen doesn't scale well at all or provide any kind of zoom out function.
I have a vnc client which performs much better but it won't connect over the vpn it only works when connected directly to the office network.
forwarding ports is out of the question. so my question is this.
is there a vnc client for pocket pc which will work over vpn or is there a way to make the remote desktop client less rubbish
also are there any apps out there that will let me browse my work network over the vpn. resco doesn't seem to be able to do it even the ftp client won't work.
am I missing something about vpn connections as it seems the only two apps that work over one are activesync and the remote desktop client.

Did you tried to acces domain controler throught the VPN? If yes it is normal that it doesn't work; Domain controler require security enhancement in auth that pocket devices cannot deliver yet. The only way I know is to reduce the security enhancement by using the GPO on the concerned servers; but this is far of being a clean fix.

Just trying to use connect to a vnc server on my workstation. btw our domain controller is the exchange server and active sync works fine

Active sync & exchange do not use the integrate authentification & kerberos; it uses a plain text auth (crypted with the SSL certs), that's why it works. Even if you are on the LAN you will not be able to access your domain's controller shares because of security enhancement.
This is far from solving your issue; but I just wanted to make it clear. Concerning your issue I can't help you at the moment, I still didnt tried the VPN & advanced networking.
btw, good luck

I have set up a vpn on my home computer, no domain, and can't access shares or a vnc server on that either.

Hi Stemill, I seen your other post about the vpn issues with Resco also, I have heard in the past about vpn issues using the [email protected], are you using [email protected] or [email protected]?
I use the terminal/remote client on a daily basis, and it does blow, vj on the board here has made an app that allows fullscreen with the terminal client, and theres a Mocha remote desktop client that supports scaling but no fullscreen, both of which have their own quirks. The scaling makes the text impossible to read when its even at 25%
I have been working on connecting to the remote desktop on mac with vnc, and I've gotten as far as an error on authentification, so I know its possible outside of a home network, but I don't have a clue about buisness situations..exchange or vpn's.
I not even 100% positive about the wap issue, I just seem to remember reading something about it in the past.
Sorry I wasn't of much help, also I kind of have a question for you, I see you mention activesync, you're not activesyncing over an internet connection are you?, I'm working on installing apps that I don't have a .cab for over an internet connection, but the best route I had figured out was to install to a ftp share and then grab the .cab from there with Resco.
Best of luck to you.

Hi there.
I'm on t-mob in the uk. They have a 3g network with full internet access so i'm not using wap at all.
Thanks for the tips about the remote client tweaks. Do you have a link?
I'm using activesync to connect to my works exchange server to sync email and calendar. Pretty sure its not possible to sync over the air to a pc without using exchange. You certainly won't be able to grab remote files via activesync.
If we could figure out how to get apps to work over vpn you could set one up on your pc and (theoretically at least) browse its contents using resco without having to bother with ftp.
If it's not possible to get stuff working over the vpn then you've probably found the best solution already. use ftp or setup a webserver on your pc and host the cab files on that. pocket ie seems to let you install cab files directly from a link.
btw which vnc client are you using on your phone?

Hi, I forget a lot of the time that people here have so many different carriers, sorry.
Here's the link to vj's terminal addon app
http://www.vijay555.com/?Releases:VJFullscreenTSC
And here's the link to the Mocha remote client app
http://www.mochasoft.dk/rd.htm
I used .Net vnc when I was able to get the authentification error
http://www.freewareppc.com/docs/netvncviewer.shtml
I think my problem on the authentification was with the apple remote desktop itself, I read about somethin in the authentification being non standard and sometimes the free vnc viewers don't work..but that was also pc to pc related, the same makers of the Mocha remote desktop also make a vnc client..that was gonna be my next try, I just haven't gotten there yet.
I inistally set up my pc to be able to remote to it from my phone and access aol chatrooms..well mainly one I have hung out in for years, then realized if I set up a server, I could install apps that I couldn't find in .cab form over the net with it, I used to have windows server 2003 set up with IIS(webserver) and the streaming media services, I'm wondering now if the windows streaming media really works with the pocket windows media, and if I could even use it with my gprs/edge connection, I'm still waiting on 3G, suprisingly the remote desktop isn't too bad on gprs/edge.
I'm currently waiting to get a new hard drive before I can really get to work, I'm testing on an old messed up xp install, and half the time I can't even access "my computer" or open folders without it crashin explorer.

Crossbow - Remote Desktop Mobile

Finally Microsoft have got their act together and provided a pretty good RDP client.
Crossbow's client is much better than previous versions offering friendly full screen support with which it is simple to toggle betweet RDP Mobile and other applcations.
(On a Full screen RDP session just press the Ok button to be presented with a Yes/No box offering to disconnect, selecting NO will leave the session intact and just , move it to the background without needing to logon again.)
Also from a fullscreen session just hit either of the buttons mapped to the softkeys to toggle back to windowed mode (Start bar visible).
Encrytion has been improved as RDP mobile nolonger requires the connection to be downgraded to Client Compatible.
I'm not forgetting the other documented features such as a coice of 256 Colours or High Colour (16 bit) and the ability to map audi from the server to the PPC.
Considering VJ's excellent VJFSTSC app was usually one of the first things to be installed after a rom upgrade I'm glad Microsoft have made their client not just usable but they have provided a long overdue (No change between 2003 & WM5) overhaul.
Taking things a little further I was surprised that Nyditot's Virtual Display works on Crossbow and the RDP client will allow a 800x600 screen (probably any res you choose) provided that the Fit to screen option is used.

Taz, I was slow to update VJFSTSC because I 'had a feeling' about remote desktop.. I don't know if there's any point continuing with my app, but I can think of some improvements to the new client, so maybe I can move in a different direction.
Many thanks for the review though. How do you find performance?
V

Try to get remote [email protected] 16 colors.

And now for a couple of pprblems with the new RDP Client
Hopefully these will be addressed by Microsoft before Crossbow/WM6 is officially released.
1. Remote Desktop Mobile will nolonger initiate a VPN through the Exceptions list within the Connections' settings. If you need to connect through a VPN you now need to connect to a VPN manually before connecting through Remote Desktop Mobile.
2. The auto fill for the Computer you wish to connect to can be a little awkward.
Once a few computers have been added, trying to connect to an additional computer with a similar name/IP to one already cached can result in RDM automattically filling in the details of a prev entered computer.
Trying to delete part of the pre-empted details results in the whole field being emptied but as you start to type the computer details again the autofill adds a previously entered computer again. The workaround is to enter the new computer name in one of the other fields and cut/paste it into the 'Computer' field.
VJ if you are considering a VJRDM application here are a few suggestions.
1. Maintain a list of computers & credential within your own application so that selecting which computer you wish to connect to will automatically launch RDM and connect to the required computer.
2. Include an option to automattically choose the Internet/Work connection and if your own database of details is maintained, allow these settings to be saved alongside the Username,Password, Domain and other settings.
3. The ability to program a WM device's hardware keys for CTRL, Esc, Alt and other Windows functions whilst using RDM without needing to reprogram these keys at the device level would be excellent
(ie launch VJRDM and the E-mail key becomes CTRL, Home becomes ALT but only whilst VJRDM is active. Whilst using other applications these keys retain their original function.)
4. Finally an option to temp disable push e-mail whilst connecting over a VPN would be handy as it would save activesync closing the VPN connection eveytime it tries to connect and shutting down the VPN.
Even with the above couple of problems DRM is far better than the terminal service client.
Does anyone know of a small application to launch a VPN without having to wade through the Connections' settings?
onlineemails I was about to suggest setting the colour depth on the server but it appears that XP and 2003 have a min depth of 8 bit (256 colours)

Hi all, is it possible to copy all the files from WM6 RDM on to a WM5 Universal, therefore being able to use the more advanced RDM on WM5?, as RDM is the ony reason i would upgrade to WM6.
Thanks

Does anyone know the file names for Remote Desktop in Crossbow?

Hi,
I am looking for a better Remote Desktop client for WM5 on my HTC Hermes.
With screen resolution setting...
Unfortunately I couldn't find anything useful.
Maybe I could use the new client from WM6.
How can I find it ?
Can anyone who has WM6, send it to me please?
Or maybe you can suggesta good client for WM5 ?
Thanks

can remote desktop be used when the universal is not connected to a home network, but through the internet with gprs/umts??
i havent got logmein working with crossbow yet :S

logmein works for me. I'm using Midgets vanilla rom at the mo.

stupid me... it does work with IE, just not with opera :$

can I use higher res than 640*480? my school's term server is requesting a minimum resolution of 800*600...

is there anyway to get wm6 remote dsektop in wm5?

i had my brother forward port 3389 from the network server to my pc and now the remote desktop works perfect with the gprs/umts connection
way better then LogMeIn

Remote Desktop software

hi all, forgive my ignorance but I would like to use my hd 2 to remotely access my home computer while out. I see the hd2 comes with remote desktop software but from what I can tell it can only be used to control computers on a lan, i.e. I'd need to be in the same domain anyway. is this correct?
z2 remote to pc is a decent piece of software ive used in the past, how well does it work on the hd2? would this new the nearest software to my needs?
tia!

its like the desktop version. it can work over the internet aswell.

Thanks - from what I've read it also supports pinch-to-zoom which is fantastic.
The only thing that concerns me is just how secure Remote Desktop is on the client side (WinXP). I guess a lot of it is down to the user to secure things, I found a decent guide here on how to minimise brute force attacks.
What appealed to me about z2 remote pc from a security point of view is that it required its own usernames/passwords to be set up as opposed to using actual Windows users and supported up to 256bit AES encryption, good stuff!
I figure I'll try both again and see how they perform.

Remote desktop from Microsoft is extremely safe to use...
For one, it uses 128-bit encryption (RC4), you login using the same login mechanisms as the windows machine... and no user with blank password or not-admin can login, so you don't suffer from that, either...

Hi guys,
You can use Logmein Hamachi Network to extend access for computers.
Go to Logmein, create an account and create a network with Hamachi.
Install Hamachi on computer do you want to connect remote, like home and work computers.
Hamachi is a VPN Network software you can use Remote Desktop Mobile to access yours computers in Hamachi Network.
There is a client for logmein Hamachi that works on HD2. Join to your Hamachi Network and use a IP Address of your computer on RDP Mobile.
The solution with Logmein Hamachi is excelent. Remote Desktop Mobile make a great job and Logmein Hamachi can connect 16 computer anywhere for free.
Try and let me know your opinion.
