You are doing the right thing, you problem is that the Platform Manager is not seeing the emulator. Do you have a valid and live IP connection?

where do you find the remote file viewer? Do you have to download the tools kit for the file loader?

I have to write a routine where i have to compact a local database in the middle of an application.
I have created a Cdatasource object and CSession object at the time of start of the application.
In the middle of the PPC application say on a button click,
i called the close method of these 2 objects, ran the command for compacting the database and opening the datasource and session again.
In the routine for compacting the database we are creating a com object.
i.e
HRESULT hr = CoCreateInstance(CLSID_Engine, NULL, CLSCTX_INPROC_SERVER, IID_ISSCEEngine, (void**)&ssceEngine);
This returned false.So it could not create the engine object,
Can any one tell me why this happened,
When i call this function in the start as soon creating a sdf file it works, but from the middle of application it doesnt,
Pls help !!!!!!!!!

Did you call CoInitializeEx?

This is what i wrote:
ISSCEEngine* ssceEngine = NULL;
bool retVal = false;
m_strLocalStorageFile = _T("C:\Tmp1");
HRESULT hr = CoCreateInstance(CLSID_Engine, NULL, CLSCTX_INPROC_SERVER, IID_ISSCEEngine, (void**)&ssceEngine);
if (SUCCEEDED(hr) && (ssceEngine != NULL))
{
CString strDestStorageFile = _T("C:\Temp");
CString strSource = _T("Data Source=");
strSource += m_strLocalStorageFile;
strSource += _T(";SSCE:Database Password=xxxx;SSCE:Encrypt Database=TRUE");
CString strDest = _T("Data Source=");
strDest += strDestStorageFile;
strDest += _T(";SSCE:Database Password=xxxx;SSCE:Encrypt Database=TRUE");
BSTR sourceFile = strSource.AllocSysString();
BSTR destFile = strDest.AllocSysString();
hr = ssceEngine->CompactDatabase(sourceFile, destFile);
}
if (retVal)
{
if (::DeleteFile(m_strLocalStorageFile))
{
// rename the file
::MoveFile(strDestStorageFile,m_strLocalStorageFile);
}
}
This code works from fine in one module but doesnt seem to work when called from another module.
The module from where it works is where the sdf file is created.
before calling the above lines of code im just closing the connection the datasource and session and opening it after running the compact routine.
I also tried calling coInitialixeEX but didnt wrk
Pls help !

If your device is iPaq,it has Widcomm Stack so you can't using MS function,
but you can use CreateFile() with COM8 and it will open your BlueTooth manager to do the pairing.
If you has MS stack,you can use MS function(WSALookupServiceBegin() etc.).

I've been toying with ATL com objects and I have a problem.
once I create the com object and load to the emulator, it works fine once,
then I get a hard error and the com can not be used again.
Does anybody have any idea of what I'm doing wrong!!!
thanks for the help!

Hi HTH,
Thanks for comment.
I'm not doing any erroring at all. Instead when i do something like this:
dim o as new my atlObject
textBox1 = o.foo 'returns a string
textBox1 = o.foo 'fails in here ..... and I get the error message....

Hi,
I am running my embedded C++ program on a Standard SDK emulator on my PC. If I want to create a file with my program, is it possible to create the file on my PC harddisk. When i create the file in the emulator, where is the location of the file?
|
|
|
|
|
the file will be created inside the emulator. the files in CE start at the root
the root is the windows directory
\windows\folder\file
use the file explorer in the emulator by going to start\programs\file explorer

Hi,
Thanks for replying. Is the anyway to make a copy of the file onto my PC harddisk? As the file will be gone everytime i close emulator rite?
|
|
|
|

I'm in the same quest!
I've gotten as far as creating the file in the emulator and browising it with the file explorer.
I've a similar need but backwards, I need to load a bitmap template file that I can reuse many times, however I have not been able to figure out how to copy a file to the emulator workarea so that it gets loaded everytime I deploy the app to the device and the doc is very skimpy or my eyesight is looking at the wrong docs...
anywho: sorry but that's as far as I am for now....

after reviewing my answer, I did some more research and found out that if you want the file to be copied to the handheld everytime you use the emulator all you have to do is copy the file into the project and then right click on the file at the solution explorer and select the build /content which is the default, i believe....
anywho, after that your file will always be loaded into the emulator whenever you want to test your program....

Hi,
I'm trying to establish a serial port between my iPaq and a Bluetooth
device.
When i call to CreateFile() with COM8(this is the only port which let me to choose the remote device i want to connect to,with the Bluetooth manager),
the connection i get is ActiveSync connection and not generic serial connection.
How can i get a generic serial connection?
My code is:
//===========================================================================
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; // 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))
{
// Could not create the read thread.
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;
}
//===========================================================================
Please help me....
