You must access the pointer value inside a critical section. Otherwise you risk having data corruption.

Hi everybody,
I am developing a collaboration application on a Win CE .NET 4.2 based device and Windows 2k/XP based devices and I am trying to remote control the CE device (e.g. like it is possible on desktops with VNC). Basically, this is possible, since it can be done with the Active Sync remote display application. However I'd like to create my own remote control and integrate it into my appliaction, hence my question is: Is it possible to use the interface the AS remote display uses? Does anybody know if this protocol/API is documented somewhere?
Thank you very much

Hi,
In order to create a virtual COM port(for BlueTooth Comunication),
I need the address of the BlueTooth device.
I know the BD_ADDR,but i must convert it to BT_ADDR if i want to use
the RegisterDevice() function.
anyone?
Regards,
Eli

First, you must know the bluetooth stack that your device has. RegisterDevice() is only supported by Microsoft Bluetooth stack. For example IPAQs uses Windcomm Stack and "RegisterDevice()" doesn't work. So if it's not microsoft Stack, you must buy the correct bluetooth Stack SDK for development.
I made a virtual serial port without "RegisterDevice()" in my IPAQ. Simply uses the normal Open port, close port , read port and write port like it'was a normal serial port. I use the COM8 in my IPAQ hx4700 and it's works. When I open the port, appears a Window Dialog (made by the own Operative System) for choose the bluetooh device to connect. If you want to do this in your own app you must use a bluetooth Stack SDK for development in your device.
Regards.

Javier

Hi Javier,
First,I really appriciate your detailed answer.
just today i saw that iPaq uses the widcom stack and not the MS stack(is that the reason i can't use WSALookupServiceBrgin() etc.)?
anyway,are you using COM8 for both incoming and outgoing massages(i use also the ipaq h2210 and it use COM5 for input and COM8 for output)
Best regards,and thanx,again
Eli

If you have a IPAQ (uses windcom stack) then you cannot use RegisterDevice. About " WSALookupServiceBrgin()" I dont know, surely not, but you can ask in the microsoft Pocket PC 's developer: http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.pocketpc.developer[^]
Yes, I use the COM8 for read and write. I saw the Bluetooth config and I saw COM5 for input too, but using COM8 both works. Simply try a sample serial com code (easy to find it, in this web there is something), using COM8 and it must work. If not, try another COM.
Regards.

Hi Javier,
I tried to open COM8,but when i open this port,and choose the remote device,
it automaticly create ActiveSync SerialPort connection(instead of generic serial connection).
Here is my code:
//============================================================================
bool PDA_BlueTooth::OutputPortOpening()
{
DWORD dwError;
DCB PortDCB;
COMMTIMEOUTS CommTimeouts;
// Open the serial port.
hOUTPUT = CreateFile(TEXT("COM8:"),GENERIC_READ |
GENERIC_WRITE,0,NULL,CREATE_ALWAYS,0,NULL);
// if it fails to open the port, return FALSE.
if ( hOUTPUT == INVALID_HANDLE_VALUE )
{
// Could not open the port.
AfxMessageBox (TEXT("Unable to open BlueTooth Output Port!!!"));
dwError = GetLastError ();
return false;
}
::SetupComm(hOUTPUT,4000, 2048);
PortDCB.DCBlength = sizeof (DCB);
// Get the default port setting information.
GetCommState (hOUTPUT, &PortDCB);
// Change the DCB structure settings.
PortDCB.BaudRate = 115200; // Current CANgine Baudrate
PortDCB.fBinary = TRUE; // Binary mode; no EOF check
PortDCB.fParity = FALSE; // Disable parity checking
PortDCB.fOutxCtsFlow = FALSE; // No CTS output flow control
PortDCB.fOutxDsrFlow = FALSE; // No DSR output flow control
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
// DTR flow control type
PortDCB.fDsrSensitivity = FALSE; // DSR sensitivity
PortDCB.fTXContinueOnXoff = TRUE; // XOFF continues Tx
PortDCB.fOutX = FALSE; // No XON/XOFF out flow control
PortDCB.fInX = FALSE; // No XON/XOFF in flow control
PortDCB.fErrorChar = FALSE; // Disable error replacement
PortDCB.fNull = FALSE; // Disable null stripping
PortDCB.fRtsControl = RTS_CONTROL_ENABLE;
// RTS flow control
PortDCB.fAbortOnError = FALSE; // Do not abort reads/writes on
// error
PortDCB.ByteSize = 8; // Number of bits/byte, 4-8
PortDCB.Parity = NOPARITY; // 0-4=no,odd,even,mark,space
PortDCB.StopBits = ONESTOPBIT; // 0,1,2 = 1, 1.5, 2
// Configure the port according to the specifications of the DCB
// structure.
if (!SetCommState (hOUTPUT, &PortDCB))
{
// Could not create the read thread.
AfxMessageBox (TEXT("Unable to configure BlueTooth Output Port"));
dwError = GetLastError ();
return false;
}
// Retrieve the time-out parameters for all read and write operations
// on the port.
GetCommTimeouts (hOUTPUT, &CommTimeouts);
// Change the COMMTIMEOUTS structure settings.
CommTimeouts.ReadIntervalTimeout = MAXDWORD;
CommTimeouts.ReadTotalTimeoutMultiplier = 0;
CommTimeouts.ReadTotalTimeoutConstant = 0;
CommTimeouts.WriteTotalTimeoutMultiplier = 10;
CommTimeouts.WriteTotalTimeoutConstant = 1000;
// Set the time-out parameters for all read and write operations
// on the port.
if (!SetCommTimeouts (hOUTPUT, &CommTimeouts))
{
AfxMessageBox(TEXT("Unable to set the time-out parameters\n for
BlueTooth Output Port"));
dwError = GetLastError ();
return false;
}
AfxMessageBox(TEXT("Output Port is open"));
return true;
}
//============================================================================
Can you give me a sample of your code,plz?????
it is driving me crazy.....
Best Regards,
Eli

There is little or no documentation on this sort of stuff on the net... however, I noticed there is something in the SDK...
If you get something working, please let me know!
I'd like to see what can be done!

Hallo,
I am doing research on what a software developer would find useful in a mobile PDA.
Do you mind droping your opinion?
regards
|
|

|

Your question is verbalized cloudly.
For the software developer it's the challenge programming within a new technology environment.
What is useful in a mobile PDA ? Only customers and standard users ask this and not a developer

Hi, I'm trying to use a thread in my app. I have read about in this web. I see that a thread must be associated to a dialog to show its variables. Now I use "AfxBeginThread" in the InitDialog and works for one dialog.
But I have several dialogs, and I want to show a thread's variable in the active dialog,not only in one of this. I need to resume or supend the thread from the active dialog, too. I'm trying but I can't do it. Anyone knows which is the best way to do it, or any sample where I can see about it? I have tried to do a extern pointer to the thread but I have a link error...
Thak you in advance.
Regards,
Javier

Well if you don^t want to use global vars, you could put your thread-object into your main class (the one derived from CWinApp). The object is then reachable by all dialogs through AfxGetApp() (cast this to the correct type).
Also you could use a singleton class with the Thread object as variable... This might be the best solution..

Hello
Does anyone knows how to control a camera for a PocketPC from a program?
Any manual or tip would help.
I'm looking for a way to get video stream from a camera in any documented format.
Thanks in advance

|

I encountered the same problem.
If you go here:
http://www.veo.com/downloads/download.asp?software=sdkPocketpc
you will find an SDK. I'm trying to use it because apparently the Veo Photo Traveller is the oem version of the HP Mobile camera...
it's a start, but I haven't gotten very far.
Let me know if you get it to work!

Thanks a lot!!!
It's even better then I've expected!
Have you found general documentation on this issue in the Internet? I would appriciate if you send me a copy.
Thanks again!

Can this SDK work on Set Top Box (STB) installed WinCE?
Now, i want to communicate with Webcam on STB. But i can't.

I have developed one such control (for MFC) and will publish it soon.
