i m using rapi function to connect with windows based mobile first time when device is connected than i run my application than its establish connection successfully.
but in mid if i reconnect the device than after connection when i chek connection with my application than it shows this error message this is i get by CeRapiGetError "the device is not ready".
please tell me what can i do.
thanks in advance.

If the RAPI server on the device does not correctly shut down after disconnection, you will see that error. Are you using a custom RAPI extension?

To shut things down you must call CeRapiUninit (as you probably are), but please make sure that all device handles are closed. I usually get that when my custom RAPI extension DLLs hang for some reason and the RAPI server becomes unavailable. I never experienced this situation with straight RAPI calls.
There's also something worth investigating: the version of ActiveSync on your PC (if you use XP, that is). For Vista / 7 make sure you use WMDC 6.1.

Hi,
I'm also using RAPI Api to connect to a Windows Mobile based Device.
And I'm also facing the problem mentioned in first thread.
Is there any way to shut down the RAPI Server on the device and restart it afterwards?
My problem seems to be exactly the same like mentioned above.
When I first connect the Device I can communicate with it perfectly and everything is
working fine.
But once I reconnect the Device I get an Error that says:
hr = 0x80070015 which is "Device not ready".
Can anyone help?
Best regards.

If your device (or RAPI extension DLL) somehow crashed, you will get this error. From my experience, the only solution to this problem is to reset the connection (disconnect and connect the device again).

Hey,
thanks for your reply.

But that is exactly the point.
This is why the error occurs.
I just found out that once CeRapiInit() is called many Libraries are loaded.
But they will not be unloaded when CeRapiUnInit() is called.
And I think that this is the point.
There are still Handles open that will block the connection upon reconnect.
I will try to figure out how to unload those Libraries and give you feedback whether that was helpfull or not.

Hey guys and girls  ,
I got the clue.
There are two very bad errors.
First thing is, that rapi.dll does NOT export a function called CeRapiUnInit().
But it does export a function called CeRapiUninit(). So most of the scripts around do have a typo.
Due to this fact you won't be able to get a pointer on that function. Thats why it will never execute.
So if you change this in your scripts you will be able to call that function.
Second thing is that CeRapiUninit() does not clean up everything for you.
You have to free the handle on rapi.dll by yourself.
If you do so, you App will free that handle and won't block another connection (e.g. on reconnect).
I now can connect und reconnect my Device as often as I like and everything works fine.
Thanks for your help again.

Hello,
I am using VS 2005 (VB.NET) for a WinCE 5.0 device (CF).
I am trying to create a form that is unmovable (locked) and full screen (with no taskbar).
I am able to create the form locked and make the taskbar disappear, but it doesn't make it full screen (it leaves a small section below where the taskbar was before as a blank area, it which is the desktop area).
I tried changing the properties for the form to no avail.
Can anyone help me? Thanks.

Do you have a sample VB.NET code that I can test using these libraries?
Thanks.

Hi
I'm trying to find out a way to either colour the background of a treeview in a .net mobile application.
I would love to be able to make it transparent or just add a background image.
Have tried various concepts but none have worked successfully so far ( maybe me ).
so far have tried wndproc - but when converting the code from c# to vb - it seemed to go a bit wonky
If there are any new ideas it would be very much appreciated.
thanks
John

Hello,
I am developing a smart device application on windows mobile 6.0, for which I want cirtain input from user at the time of deployment.
So could anyone tell me how can I make an interactive CAB or how can I add user interface to CAB project.
Thanks in advance.
Mayur.

add a setup.dll to your CAB and there you can show a dialog in install_exit() or whenever you need it.

Hi,
sorry for cross posting - I'm a bit overworked and didn't see that there's a mobile dev forum.
I'm working on a Windows Mobile application that connects to a server on a PC.
The problem with the following lines:
CSocket as;
if(!as.Create())
MessageBox(_T("creation failed"));
if(as.Connect(_T("192.168.1.24"), 110))
MessageBox(_T("connected"));
else
MessageBox(_T("failed to connect"));
is, that Connect(...) allways returns TRUE, even if the server isn't started and even if the PC with the IP address 192.168.1.24 is switched off.
This error only occures with Windows Mobile and a WLAN connection. On Windows XP/Vista connected via WLAN/LAN or Windows Mobile connected via USB Connect(...) returns FALSE when there's no server.
Any hints?
Thanks,
Thomas
ps.: to be a bit more precise - the problematic connection is from a PDA via WLAN to a Netgear internet router and the PC is connected via LAN

Hi All,
I have a question regarding RSS...I am currently using web service to download data from server database to my mobile device(client) using web service which acts as a data access layer.Also through RSS we can download data...
1) Wat exactly is the difference between the two,Web service and RSS in terms of data fetch??
2) In what scenarios can we opt for RSS(business use case)?
Also when we create an xml doc on the server side how is it different from RSS i.e how can we say that it is an RSS feed?
Kindly provide pointers to the above mentioned querries.
Thanks in advance

Hi 
A web service is a vague description of a remote service capable of reading requests made, most likely, over http and replying according to a predefined set of rules.
A "Service" in this case is an interface to underlying appliction/applications.
The communication scheme, syntax and process rules, is also commonly called protocol. Such protocols include XML-RPC, SOAP and REST.
RSS, Atom are examples of definitions for stuctured data such as news items etc
In a web service call, such as an XML-RPC or SOAP call, you can include content such as RSS or Atom.
A simple top down example of dependances in a web service call:
RSS (Human Readable Data)
|
V
SOAP (Method Call Defenition Protocol)
|
V
HTTP (High Level Transport Protocol)
|
V
TCP-IP (Low Level Transport Protocol)
What you are aiming at, i guess, is the manner to make calls and handle responses,
* REST (Representational State Transfer) services include most RSS and ATOM feeds. REST means that you use HTTP (GET,PUT,DELETE) as protocol for retrieving (GET), updating (PUT) and deleting (DELETE) items on the remote end. REST skips the overhead of SOAP/XML-RPC and is a very fast and light weight way of communicating with a web service.
* SOAP (Simple Object Access Protocol) is however the most supported way of sending requests and recieveing responses on the CE platform. It is actually the technology of choice for the entire .NET paradigm. Its rather bulky though...
* XML-RPC (XML Remote Procedure Call) is a very simplified protocol way of making Web Service calls. Because of its simplicity this is the choice for many developers outside the MS sphere.
Hope this helps,
Lars

A first chance exception of type 'System.Net.WebException' occurred in System.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Web.Services.dll
while the error message i get is this:

Regarding the first chance exception, I would tell you that you might not need to worry about sometimes.
