Re: ReleaseDC doesn't release memory

14-Dec-04 21:22

Hi,
I don't really see the problem,but try to change the timer interval(i don't think that GetDC() and ReleaseDC() takes more than 200msec,but maybe it's the problem).

Good luck
Eli

I already tryied but it doesn't change. Thank you anyway.
I fixed the problem using handles instead of pointers for the dc, but I really don't understand why it happens.

Pointer to severals Dialogs

Re: Pointer to severals Dialogs

9-Dec-04 1:25

Hi, I need to have a pointer to a dialog window from a thread. I made a global pointer variable to a dialog window and it works. But Is it possible to do a pointer which can pointer to several dialogs (one at the same time)?

I need to pointer to the active dialog from the thread(the active dialog window it's not the same all the time). I try "void* pointer" but doesn't work, (there'is a error in the reference to the pointer inside the thread).

Regards.

Javier

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

CE remote display / VNC?

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 Smile | :)

How to convert BD_ADDR to BT_ADDR?

8-Dec-04 1:23

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.

Javier

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.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.....

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.

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..
