Does anybody know how to get Device Information on XDA(Wallaby, Himalaya and Blue Angel) from within C++?
I would like to get the RomVersions(ROM,Radio etc.) and Dates.
And also Modell Number, IMEI.
Nearly the same as you can see under Start->Settings>System: Device Information.
I read somethimg about a "disk on chip" document, but it is linked under wiki, and it seems to me that everything und wiki(sourceodes, documents etc.) is dead.
Ok, i have some of these things.
I get the Model-Nr, Platform String, IMEI, and the OS Version.
With this Information i can say what XDA Device i´m running on.
But i don´t know how to get the ROM Informations.
Does anybody know where to find them? On XDA3 i found Versiosn in Registry, but they are not avaible on XDA1, and not all avaible on XDA2.
Maybe i have to Get the FileVersions and Dates...
Device Information
Hi I'm new in PDA and I'm looking for c++ code to reed information about device serial number or IMEI (for MDA 2 or MDA 3). Could You help me.
Thanks for any information
Tom.

Thanks for your code but I cand compile it error like:
error C2065: 'TAPI_API_HIGH_VERSION' : undeclared identifier
error C2065: 'TAPI_API_LOW_VERSION' : undeclared identifier
error C2065: 'CELLTSP_LINENAME_STRING' : undeclared identifier
error C2065: 'EXT_API_LOW_VERSION' : undeclared identifier
error C2065: 'EXT_API_HIGH_VERSION' : undeclared identifier
what should I include ?
#define TAPI_API_LOW_VERSION 0x00020000
#define TAPI_API_HIGH_VERSION 0x00020000
#define EXT_API_LOW_VERSION 0x00010000
#define EXT_API_HIGH_VERSION 0x00010000
OK but what with this one:
error C2065: 'CELLTSP_LINENAME_STRING' : undeclared identifier
thanks
#include <tapi.h>
#include <tsp.h>
#include "extapi.h"
#define TAPI_API_LOW_VERSION 0x00020000
#define TAPI_API_HIGH_VERSION 0x00020000
#define EXT_API_LOW_VERSION 0x00010000
#define EXT_API_HIGH_VERSION 0x00010000
Now is OK
.. but I have one question whay it dsn't work without SIM card ? Is it possible to get IMEI or device serial number if there aren't sim inside ?
Yes, it does work without simcard. It runs on my MDA 1/2/3 without SIMCard.
Maybe you phone decivce is completely turned off...
Yes you right phone device was turned off now is goood
Thanks
hmmm - are you writing this app in eVC++ 3.0 or eVC++ 4.0 ?? I dont seem to get it working in eVC++ 4.0. I'm getting an external link error for lineGetGeneralInfo().
Could you be kind enough to send me the full app ??? or help me solve this ?? i'm trying to write my program as a MFC pocket pc 2003 exe and dialog based!!
thanks
problem solved , thanks for the source code
has anybody used this as a utility to craete an output fie containing the IMEI number? I have'nt got Visual Studio for pocket PC but would like to be able to do this

My phone device is completelty turned off.
Do you have any idea how to find IMEI number when the device is in this state ?
It's possible because system info in control panel could display the IMEI in this state.
Hi everybody!
I know this is a bit off topic but if you want to get a serial number instead of IMEI you can use the following code:
Code:
#define IOCTL_HAL_GET_DEVICEID CTL_CODE(FILE_DEVICE_HAL, 21, METHOD_BUFFERED, FILE_ANY_ACCESS)
extern "C" BOOL KernelIoControl(
DWORD dwIoControlCode,
LPVOID lpInBuf,
DWORD nInBufSize,
LPVOID lpOutBuf,
DWORD nOutBufSize,
LPDWORD lpBytesReturned);
BYTE outBuff[16];
*(DWORD*)outBuff = 16;
KernelIoControl(IOCTL_HAL_GET_DEVICEID, 0, 0, outBuff, 16, &outBytes);
Should work on all devices regardless of what is turned on.
Thanks.
With the DEVICEID information, IMEI could be found with phone device turned off on QTEK 9090
Code:
void GetIMEIFromQtek9090(char *serial)
{
BYTE outBuff[16];
DWORD outBytes;
*(DWORD*)outBuff = 16;
KernelIoControl(IOCTL_HAL_GET_DEVICEID, 0, 0, outBuff, 16, &outBytes);
sprintf(serial,"35%02X%02X%02X%02X%02X%02X%02X", outBuff[6], outBuff[5], outBuff[4], outBuff[3], outBuff[2], outBuff[1], outBuff[0]);
}
Thanks again.
Any luck obtaining the device ROM version? It's the only item in your list that I seem to be stuck on...
Can someone send me a compiled version of the code to get the IMEI etc?
For the program I posted here, I want to handle incoming calls before the default popup appears (to replace the ringtone).
Currently, my tool seems to be quick enough without lineSetAppPriority in most cases, but sadly not in all...
I was using the following code: (currently removed again, because it didn't work and even caused some troubles...)
Initialization:
Code:
if ( lineInitialize( &LineApp, theApp.m_hInstance, LineCallback,
theApp.m_pszAppName, &LineHandleCount ) == 0 )
{
LineHandles = new HLINE[LineHandleCount];
for(DWORD i = 0; i < LineHandleCount; i++)
{
if ( lineNegotiateAPIVersion( LineApp, i, 0x00010000, 0x00020000,
&ver, &extensionID ) == 0 )
{
rc = lineOpen( LineApp, i, &LineHandles[i], ver, 0, (DWORD)this,
LINECALLPRIVILEGE_MONITOR|LINECALLPRIVILEGE_OWNER,
LINEMEDIAMODE_INTERACTIVEVOICE, NULL );
if ( rc < 0 )
LineHandles[i] = NULL;
else
if ( LineHandleSignal == NULL )
LineHandleSignal = LineHandles[i];
}
}
HRESULT res = lineSetAppPriority( theApp.m_pszAppName,
LINEMEDIAMODE_INTERACTIVEVOICE,
NULL,
LINEREQUESTMODE_MAKECALL,
NULL, 1 );
}
Callback:
Code:
VOID FAR PASCAL LineCallback( DWORD hDevice,
DWORD dwMsg,
DWORD dwCallbackInstance,
DWORD dwParam1,
DWORD dwParam2,
DWORD dwParam3
)
{
if ( dwMsg == LINE_CALLSTATE )
{
LINECALLINFO *callInfo = (LINECALLINFO *)calloc(sizeof(LINECALLINFO)
+1024, 1);
callInfo->dwTotalSize = sizeof(LINECALLINFO)+1024;
lineGetCallInfo( (HCALL)hDevice, callInfo );
// different stuff...
HRESULT res;
// Remove from priority list, so lineHandoff will run the default
// call window
res = lineSetAppPriority( theApp.m_pszAppName,
LINEMEDIAMODE_INTERACTIVEVOICE, NULL,
LINEREQUESTMODE_MEDIACALL, NULL, 0 );
// Forward event to next instance (usually Windows' phone app)
lineHandoff( (HCALL)hDevice, NULL, callInfo->dwMediaMode );
// Set to top priority again
res = lineSetAppPriority( theApp.m_pszAppName,
LINEMEDIAMODE_INTERACTIVEVOICE, NULL,
LINEREQUESTMODE_MEDIACALL, NULL, 1 );
}
lineSetAppPriorty returns OK in all cases. But when a call comes in, the
default bubble applears simultaneously with the callback function. I
wanted it to be shown when I do the lineHandoff...
What am I doing wrong?
TIA,
Mirko
I used lineSetAppPriority too, with same result....
I think there is one way.....kill cprog
I am presently writing a RegEdit program to run on my PC and allow editing of the registry on the connected PPC. I have got to the point where I can read the entire registry and I am now implementing function to update the registry i.e. insert new key, delete key, add new Key Values etc...
The problem I have at the moment is trying to add a new value to an existing key. The function I have written so far to do this is as follows, but the call to CeRegSetValueEx(...) returns an error code 5!
Code:
//-----------------------------------------------------------------------------------
// Adds a new key value into the registry.
// // TO DO - add the data
int CRegEditDoc::AddNewKeyValue(HTREEITEM hParent, HKEY hRoot, LPTSTR lpszKey, LPTSTR lpszValueName, DWORD dwType)
{
USES_CONVERSION;
int nItem, rc;
HKEY hKey;
LPWSTR lpwszKey = T2W(lpszKey);
LPWSTR lpwszValueName = T2W(lpszValueName);
try
{
if (lstrlen (lpszKey))
{
if (m_rapi.CeRegOpenKeyEx (hRoot, lpwszKey, 0, 0, &hKey) != ERROR_SUCCESS)
{
return 0;
}
}
else
{
hKey = hRoot;
}
CString strValue = "my data";
LPWSTR lpwszData = T2W(strValue);
DWORD length = dim(lpwszData);
nItem = m_pRightView->GetListCtrl().GetItemCount();
if (m_rapi.CeRegSetValueEx(hKey, lpwszValueName, 0, dwType, (LPBYTE)lpwszData, length*2) != ERROR_SUCCESS) // last 2 lpData, szie in bytes of data.
{
HRESULT hResult = m_rapi.CeRapiGetError();
DWORD dwError = m_rapi.CeGetLastError();
return 0;
}
}
catch (CException* e)
{
TCHAR szCause[255];
e->GetErrorMessage(szCause, 255);
CString errorMsg = _T("Error in: CRegEditDoc::AddNewKeyValue: ");
errorMsg += szCause;
AfxMessageBox(errorMsg);
e->Delete();
}
return 1;
}
I would appreciate a little advise on the matter, as this is the first time I have used the RAPI.
Thanks.
Hi VZ800!
The error you're getting is 'access denied'. In WM5 many RAPI functions (including writing to registry) are blocked for security reasons. Your only choice is to use a dll with CeRapiInvoke functions, but it needs to be deployed through a special cab.
You can read about this on msdn.
By the way, the app you're writing already exists, and it has the same problem.
Good luck!
Thanks for the advice. Since my post I have found that my code works for the HKEY_LOCAL_MACHINE, "/Software".
I will investigate the issue you have pointed me to.
Actually, your code should work for the entire HKEY_CLASSES_ROOT as well. MS decided to block only certain 'sensitive' parts of the registry so they can not be corrupted from the outside by malicious software.
If you noticed, MS's own remote registry editor works through DLLs (a ton of them).
Any way, I skimped on words in my first post, since I was writing it on a bus, and while I love my Jamin, writing long text on it is not very enjoyable.
Let me elaborate on CeRapiInvoke:
It's a function you call on the PC side that receives a DLL name and a function name (in that DLL) as parameters and calls that function on the device. It also lets you transfer buffers of data to and from the called function.
It's a great way to communicate with a PPC device without using sockets. You can write the device side DLL to do what ever you wont (like access protected registry) and report back to the PC.
The only drawback is in WM5 this DLL has to be registered and have a 'system' file attribute set. That's why you have to deploy it by cab.
Like I said before it's all in the MSDN.
Hope this helps.
Thanks. I have read the articles (and printed them) about RAPI Restricted Mode Security etc... http://msdn.microsoft.com/library/d...5/html/wce51conRAPIRestrictedModeSecurity.asp and will write a DLL to go on the PPC which will be installed via CAB etc...
I updated the function to add a new value anyway. Rather than calling the RAPI functions for the registry CeRapi... I will call my own functions in my authorised DLL.
Code:
//-----------------------------------------------------------------------------------
// Adds a new key value into the registry.
//
int CRegEditDoc::AddNewKeyValue(HTREEITEM hParent, HKEY hRoot, LPTSTR lpszKey,
LPTSTR lpszValName, DWORD dwDType, LPBYTE lpData)
{
USES_CONVERSION;
HKEY hKey;
LPWSTR lpwszKey = T2W(lpszKey);
LPWSTR lpwszValName = T2W(lpszValName);
DWORD dwDSize = sizeof(lpData);
try
{
if (lstrlen(lpszKey))
{
if (m_rapi.CeRegOpenKeyEx (hRoot, lpwszKey, 0, 0, &hKey) != ERROR_SUCCESS)
{
return 0;
}
}
else
{
hKey = hRoot;
}
// Check if valuename already exists. Should never happen, but just in case.
if (m_rapi.CeRegQueryValueEx(hKey, lpwszValName, 0, &dwDType, NULL, &dwDSize) == ERROR_SUCCESS)
{
AfxMessageBox(_T("Value of this name already exists!"));
return 0;
}
if (m_rapi.CeRegSetValueEx(hKey, lpwszValName, 0, dwDType, lpData, dwDSize) != ERROR_SUCCESS)
{
HRESULT hResult = m_rapi.CeRapiGetError();
DWORD dwError = m_rapi.CeGetLastError();
AfxMessageBox(_T("Unable to create new value for this key!\nPlease check access rights."));
return 0;
}
}
catch (CException* e)
{
TCHAR szCause[255];
e->GetErrorMessage(szCause, 255);
CString errorMsg = _T("Error in: CRegEditDoc::AddNewKeyValue: ");
errorMsg += szCause;
AfxMessageBox(errorMsg);
e->Delete();
}

A question on using the CeRapiInvoke function. Obviously my function that I will be invoking in my DLL will need to conform to the following footprint:
Code:
LPCWSTR, LPCWSTR, DWORD, BYTE*, DWORD*, BYTE**, IRAPIStream**, DWORD
What I would like to know is this: If I want my function to be a wrapper to say the
Code:
CeRegQueryValueEx(HKEY, LPWSTR, LPDWORD, LPDWORD, LPBYTE, LPDWORD)
function, how do I parse the function args? Please suggest how I would pack them into a BYTE* for the pInput parameter.
Actually, you got it a bit wrong:
Code:
FuncName(DWORD cbInput, BYTE *pInput, DWORD *pcbOutput, BYTE **ppOutput, IRAPIStream *ppIRAPIStream);
The prototype you specified is for the PC side (the first two strings are DLL name and function name);
I use the following parsing method:
Code:
BYTE* curInputPos = pInput;
memcpy((BYTE*)&hKey, curInputPos, sizeof(HKEY));
curInputPos += sizeof(HKEY);
memcpy((BYTE*)&dwIndex, curInputPos, sizeof(DWORD));
curInputPos += sizeof(DWORD);
memcpy((BYTE*)&Reserved, curInputPos, sizeof(DWORD));
curInputPos += sizeof(DWORD);
It works fine both ways.
Just don't forget to use LocalAlloc for inBuffer and LocalFree for outBuffer.
Thanks. I'll let you know how I get on.
So if I were to parse an HKEY and an LPTSTR accross I would do the following to put the data into a BYTE array:
Code:
DWORD dwIn, dwOut;
LPBYTE pInput;
PDWORD pOut;
dwIn = sizeof(HKEY) + (strlen(lpszKey)*sizeof(TCHAR));
pInput = (BYTE*)(LocalAlloc(LPTR, dwIn));
memcpy(pInput, (BYTE*)&hKey, sizeof(HKEY));
pInput += sizeof(HKEY);
memcpy(pInput, (BYTE*)&lpszKey, strlen(lpszKey)*sizeof(TCHAR));
// move pointer back to begining.
pInput -= sizeof(HKEY);
Basically, yes but with two reservations:
1) I recommend using a different pointer for the current position in buffer, to avoid errors.
2) you need to put the string length in the byte array before the string, otherwise you won't know it's length on the device side. Alternatively, you have to add 1 to the length so the 0 byte at the end gets packed and you can use strlen on the device.
Also keep in mined that unless you define the PC side project to work with UNICODE libraries, THCHAR will be defined as char, while on the device it's always WCHAR.
I really apreciate your help. I still can't get my DLL function to work I keep getting error 1064!
This is my code for the DLL named REditSvr.dll:
Code:
#include <windows.h>
#ifdef __cplusplus

{
#endif
__declspec (dllexport) INT RegEditDeleteValue (DWORD cbInput, BYTE* pInput, DWORD* pcbOutput, BYTE** ppOutput, PVOID reserved);

{
return TRUE;
}
INT RegEditDeleteValue (DWORD cbInput, BYTE* pInput, DWORD* pcbOutput, BYTE** ppOutput, PVOID reserved)
{
INT rc = 0;
BYTE* curInputPos = pInput;
HKEY hKey;
DWORD dwLength;
// Copy args out of input buffer.
memcpy((BYTE*)&hKey, curInputPos, sizeof(HKEY));
curInputPos += sizeof(HKEY);
memcpy((BYTE*)&dwLength, curInputPos, sizeof(DWORD));
curInputPos += sizeof(DWORD);
// Allocate enough memory for local wchar.
LPWSTR lpszValueName = (WCHAR*)malloc(dwLength);
memcpy((BYTE*)&lpszValueName, curInputPos, sizeof(dwLength));
curInputPos += sizeof(dwLength);
// Do the registry delete.
rc = RegDeleteValue(hKey, lpszValueName);
// Allocate memory for the return buffer.
BYTE* pOutput = (BYTE*)LocalAlloc(LPTR, sizeof(long));
memcpy(pOutput, (BYTE*)rc, sizeof(long));
*ppOutput = pOutput;
*pcbOutput = sizeof(long);
// Free input buffer.
LocalFree(pInput);
// Free WCHAR
free(lpszValueName);
return GetLastError();

The DLL has been deployed to the PPC \Windows folder by eVC4. My PPC runs WM5 (is this the problem, although I have written programs with eVC4 ok for it).
I would again appreciate your help/advice on why this isn't working. At present I have unlocked my PPC and I am able to edit any part of the registry etc...
Hi VZ800!
I noticed a couple of errors in your code (which you may have corrected yourself by now) but the biggest problem, I think is that you don't register the dll.
Here is the part you missed from MSDN:
(full link: http://msdn.microsoft.com/library/d...en-us/mobilesdk5/html/mob5lrfcerapiinvoke.asp)
To satisfy the requirements of the Remote Access Security Policy
1. Create a provisioning XML document that adds the new node "RAPI" to the metabase. This node must include the absolute path to the *.DLL file. For more information, see Metabase Settings. The following code example shows the contents of a typical provisioning XML file.
<wap-provisioningdoc>
<characteristic type="Metabase">
<characteristic type="RAPI\Program Files\Green Sky\recaller.dll\*">
<parm name="rw-access" value="3"/>
<parm name="access-role" value="152"/>
</characteristic>
</characteristic>
</wap-provisioningdoc>
2. Pass the file name of the provisioning XML document to the CAB wizard using the /postxml command line option. The CAB wizard will append the XML to the _setup.xml file it places in the CAB. For more information on creating CAB files, see CAB Wizard.
3. Set the System attribute on the *.DLL file.
Only the Manager security role provides the required permissions for modifying the metabase. The ideal way to get this security role is to have your application signed with a privileged certificate.
Note Since Pocket PC implements a one-tier security model, the CAB install process will automatically have the Manager security role.

Here's my advice:
Create a simple function that doesn't receive parameters, but pops up a message on the device. When you see that calling it works, try adding the rest of the code.
Hi
As I understand the DLL does not require code to self- register. Anyway, I can call the DLL function and did as you suggested and put a MessageBox in the function. This displayed fine. My code for the DLL is as follows now:

As you can see in the DeleteKeyValue(...) function I called a test-function just to check that I was retrieving the data out of the pInput buffer ok, which I am.
I signed the DLL with the SDKSamplePrivDeveloper.pfx, added the /postxml via the /postxml switch in the cabwiz and successfully created a CAB file which installs the DLL into the \Windows folder on the PPC. The .inf file is as follows:
Code:
[CEStrings]
InstallDir=%CE2%
AppName="REditSvr"
[Strings]
CompanyName="AHartley"
[Version]
Signature="$Chicago$"
CESignature="$Windows CE$"
Provider=%CompanyName%
[SourceDisksNames.Arm]
1=,"arm files",,C:\eMDevelopment\PPCRegEdit\REditSvr\REL
[SourceDisksFiles.Arm]
REditSvr.dll=1
[Files.ARM]
REditSvr.dll
[DestinationDirs]
Files.Arm=,%InstallDir%
[DefaultInstall.Arm]
CopyFiles=Files.Arm
My PC side code invokes the DLL function return 0 as error code. But the error code returned in the ppOutput buffer is 0x00000057 Dec 87. Which equates to the error message "The parameter is incorrect."! Which must be a param of the RegDeleteValue(...) function, as if I comment this out I don't get any error return values!!
Any odeas?
This is all academic now as I won't be finishing the PPCRegEdit program coz of the Remote Registry Editor tool available in the eVC4 IDE, which I hadn't noticed before, duh. But I would like to know why the function isn't working as required.
You were writing this as a tool? :shock:
If you just asked, people would have told you about the existing reg edit and CeRegEdit witch works through RAPI directly.
Still, it is a nice exercise in coding which I done my self once (for other purposes)
Any way, your error is simple:
Code:
// Value name string.
memcpy((BYTE*)&lpszValueName, curInputPos, sizeof(len));
curInputPos += sizeof(len);
You are parsing it incorrectly.
This is how it should look:
Code:
// Value name string.
memcpy((BYTE*)lpszValueName, curInputPos, len);
curInputPos += len;
and on the PC side:
Code:
memcpy(pCurInputPos, (BYTE*)&lpwszValName, len);
should be:
Code:
memcpy(pCurInputPos, (BYTE*)lpwszValName, len);
once again, no offence but if you just read your code more carefully and use debug prints to check parameters, you won't need anyone's help.
Good luck in future projects.
(whoops, made an error my self while correcting another)
Yes, it is just an exercise.
Thanks for all your help. Sorry for the silly errors, I will try and take more care in future.
