I derived a class from CCeSocket.
The object of that type that I use in my app is dynamically created.
I can connect and communicate correctly with the server-application using that object, the problem is that when the object gets destroyed that in DEBUG mode the application sometimes crashes. (In Release all seems to run correct)
The assertion error refers to wcesock.cpp line 733. Looking there it seems as if a thread created by the CCeSocket is still trying to access the socket. (My app is single threaded by the way). The crash does not happen every time though.
Should I wait for a certain event after I close the socket before I delete the socket-object? Or is this a known problem when running in DEBUG mode... Could something else be at fault?
I just want to avoid a crash ever happening in Release, so I don^t want to just ignore this warning without knowing for sure that it can't harm ignoring it...
Thanks for any help you might provide,
With Friendly Regards,
Davy

Hi,
When I read document about Windows CE registration in Microsoft Windows Website(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcemain4/html/cmlrfDefaultRegistrySettings.asp), it says "Like ISAPI dynamic-link libraries (DLLs), the Web server keeps Asp.dll and any libraries that ASP loads — including JScript.dll, VBScript.dll, and any DLLs that contain COM objects that were created on the page — in a cache. The Web server unloads the DLLs in this cache automatically if they have not been used for 30 minutes. This delay is defined by a setting in the system registry." But I can't find out which registry sub key is responsible for this delay, so does anyone has any idea about it? Thanks very much in advance!

hi all,
Synchronization provides a means to compare two Object Stores, analyze their differences and then modify each Object Store so that the two are identical.
i wanted to sync my nokia phone data to my pocket pc windows ce device over bluetooth.
for that i am planing to write a application for my pocket pc.
what are all the various data sync standards available in the market ?
To support all the mobile phones(such as nokia, motorola, samsung and etc.,, how difficult it is to implement ?
any body is having idea about sync standards ?
please explain me in detail.
regards,
aks

Hi, I'm developing an application for a pocketpc2003 based device. Now I have to port this application to a Windows CE based device.
In my application I used FindFirstFlashCard() to detect a storage on the device, but this function is part of PPC SDK. What can I use to detect if there's a flashcard (a storage card) on the winCE device?

I believe you will have to ask the device manufacturer for that information.

Hi,
I have to host WebService in WinCE .NET.
I have written ATL COM Component in embedded VC++ ,and generated WSDl/WSML files using tool wsdlstb_ce.exe .
I am using ComplexTypes in my WebMethods,for that i have written COM Component implementing ISoapTypeMapper.
Modified WSML file accordingly e.g.
<servicemapping name="Service">
<service name="Service">
<using progid="Service.MyService.1" cachable="1" id="ServiceObject">
<using progid="Service.ComplexTypeMapper.1"
="" cachable="1" id="ComplexTypeMapperObject">
<using progid="Service.StatusMapper.1"
="" cachable="1" id="StatusMapperObject">
<types>
<type name="Complex1" targetnamespace="http://temp.org/webservices/"
="" uses="StatusMapperObject" iid="{xxxx-xxxx-xxxx-xxxx-xxxxxxxxx}">
<type name="Complex2"
="" targetnamespace="http://temp.org/webservices/" uses="ComplexTypeMapperObject" iid="{xxxxxx-xxxx-xxxx-xxxx-xxxxxxx}">
------------------------------------
------------------------------------
Now when i call WebMethod from client on PC (sending Complex Types as a parameters)It goes in Constructors of all the COM Components (e.g. Service,ComplexTypeMapper,StatusMapper) after that it throws the Exception of type
"System.Web.Services.Protocols.SoapExceptions"
"Additional Information:Error Source :Server"
How can i see, where this exception is occuring on WinCE hardware??
what is this exception?????
Thanks

I have proprietary hardware that contains a host controller that can
enumerate PPC 2003 devices. When a PPC 2003 device is attached to our
hardware, our hardware enumerates the device then waits for the device to
send data to it, specifically waits for a hex 5. Once it receives the hex 5
it returns a hex 6. We have built in debug monitoring on our hardware that
allows us to see all incoming and outgoing data. Using the serial over USB
driver interface that’s a part of the COM driver we can successfully send a 5
down as well as any other data we want. The issue comes in when we send data
from the host, i.e. a 6, back to the device running PPC 2003. No matter how
long we read for on the device nothing ever comes back but the host is
definitely returning data. I also tried setting up a WaitCommEvent on the handle and have it signal when a EV_RXCHAR event came in. This event is never getting flagged.
Again we are using the Serial over USB driver included with PPC 2003 to
communicate with the host controller. The drivers interface type is
4294967295 and its key is Drivers\BuiltIn\SerialUSB. I did check and although
the specific index the SerialUSB driver resides on changes i.e. COMx:, the
interface remains the same. Does anyone know if there is something special
you have to do to read data being sent over USB on the device? Is data read
on a different Com? Thanks for your help in advance.

Hi,
First - check the pins of both sides of the RS232 connector(are you sure the TX of one side goes to Rx of the other?).
Also - you should check if your H/W uses Flow Control etc.
if so - check if all the pins are connected.
Good Luck,
Eli

Well when I say Serial over USB that isn't with a special cable. That's how the communication between a PPC 2003 and the desktop occurs. The PPC doesn't use a standard serial cable it has a special connector you plug into the bottom that has a male USB connector on the other. It's pretty hard to have them not connected because both ends pretty much lock in. I've pretty much tried every combination of serial settings on the device possible but to no avail. And again I can send data down but I can't receive it back. I'm beginning to think it may be an issue in how our hardware is enumerating the device. If anyone has tried to use the serial over usb driver that is a part of PPC 2003 please let me know, thanks.

Hi,
I could not find any info on this anywhere some maybe someone here has an idea?
When I create a dialog with a button (CButton) and the stylus is held down on the button for an extended period the the red dots from tap and hold do not appear. This is good.
When I create a CBitmapButton and the stylus is held down the red dots do appear. This is bad.
How do I disable tap-n-hold for owner draw (CBitmapButton) buttons ?
Thanks Tom.

Never mind -
Here is the solution
Derive your own class from CBitmapButton and override the OnLButtonDown function.
void CMyBitmapButton::OnLButtonDown(UINT nFlags, CPoint point)
{
Default();
}
