Getting own phone number or SMS Service Number from a POCKET PC

Getting own phone number or SMS Service Number from a POCKET PC

• Elijah Niño D. Mondero

  be sure to debug the example in PHONE version emulator ;)

  but more probably phone number is not stored in emultor

  Hi, I'm having the same problem.
  I re-wrote this in C#, and for wm6 based pocketpc phones I get an empty string for the phone number. I get a dwAddressOffset of 228 and a leng of 2 (a unicode null terminator).
  
  Running GetPhoneNumber.exe from the WM6 SDK has the same problem.
  
  Any hints as to how to get the phone number out of the phone Is it possible at all

  I really doubt if its possible. cuz the code specifically mentions that it works only if the SIM card has the phone number programmed into it, which in most cases it not so.

  This function doesn't work. I have tested on many devices and in most of the devices it doesnot retrive the number, it gives only "".

  Hi Crino,
  Thanks for your help but I need more explanation.
  Can you tell me what are these parameters( LPTSTR szNumber, UINT cchNumber, UINT nLineNumber ) briefly
  I am expecting your answer.

  The problem on Pocket PC is that the Value of pLineDevCaps+pLineDevCaps->dwLineNameOffset is not equal to CELLTSP_LINENAME_STRING which has been set to "Cellular Line" is tsp.h of Pocketpc.

  For Pocket PC below values of pLineDevCaps+pLineDevCaps->dwLineNameOffset are displayed:

  Serial Cable on COM1:

  Infrared Port

  Bluetooth

  Bluetooth device

  Generic IrDA

  Hayes Compatible on COM1:

  But none still give the phone Number.

  Does anyone know what must the value of CELLTSP_LINENAME_STRING be set for PocketPC in the tsp.h header file

  Hi Gurhan,
  take a look on lineGetAddressCaps function.

  }

  delete[] pCapBuf;
  } // End if ()

  FuncExit:
  lineShutdown(hLineApp);

  return hr;
  }

  example taken from WM5' SDK

  I hope this help ;)

  szNumber could be a TCHAR[] variable (eg: TCHAR szNumber[255])

  cchNumber is the szNumber's length (eg: 255 for szNumber[255])

  nLineNumber is the line's number to open in TAPI

  Please check the example in WM5' SDK (GetPhoneNumber)

  Bye

  Hi again,
  
  Firstly, thanks for help. But there is a problem, in the function, dwAddressSize is always zero. So it can not find a phone number Is it something about nLineNumber Which other numbers should I try instead of 1 Also I got the example project but I can't run it because after a successful deployement, Visual Studio 2005 gives this error:
  
  Unable to start program '%CSIDL_PROGRAM_FILES%\GetPhoneNumber\GetPhoneNumber.exe'
  
  Thanks very much again.
