I'm trying to create my first project, but I can't select all of the CPUs in the drop down list.
Why do some of them grey out and some don't?
Thanks

It depends on the SDK support for the CPUs. For instance, Pocket PC SDKs will only support ARM and emulator.

hello everyone. I am in deep sh*t now. i have to develop a biometric authentication system which apply neural network algorithm , that is using handwritten signatures to authenticate users instead of combination of user id and passwords. I do not even know which language to use, some told me MATLAB, some said VB. so can anyone give guidance or sample source code to me so that i do not need to start from scratch since the time is running out.
thanks a lot and please help pass this message around so that i can have more things to refer

It sounds like :
1. You have chosen the biometric - signatures.
2. That you are going to train a NN to recognize signatures.
Given this, it sounds like you just need to search for open source NN code.
Likely be able to google for sample code in any language you want.
Some of the questions that come to my mind are :
- What is the authentication for ? Logging in, proving that a particular person signed a document, ... . In either case PKI is likely much more appropriate.
- Do you have to use a signature as the metric, can you use fingerprints or retinal scans ?
- Do you have to use a NN for matching ?

thanks to u cmk, yes, u r rite, i have to search open source code for NN n train NN matching. Too bad i can't find any source code available online. That makes me so frustrated. so it will be great if you can provide me the related source codes or useful link.
Its a program for logging in. Anyhow, i just intend to build a program that can store handwritten signatures and compare with input data later, n thats it.
thanks folks.

wei thank u very much cmk, i owe u once. That link u gave me indeed helped me on the problem. thanks again n hope u have a nice day. mind giving me email address? i think we could be friends and discuss programming matters from time to time.

I'm a developer with the new protocol IPv6, and I've surprised when I see that the actually compact framework doesn't support this protocol.  I think that It's a big error by microsoft because if Pocket PC 2003 support ipv&, compact framework also should support it.
I'd like, if any way for create a socket connection with ipv6, in .NET?
Thanks for all!!

Hi ALL,
I need to access the Windows CE SQL server using OLEDB API's.
Is there any OLEDB c++ warapper class for communicating to the Windows CE SQL server 2.x ?
Suggestions are most welcome.

Hi,
Thanks for your reply. Also, i have seen samples which is coming along with the SQL server 2.0 which does not uses OLE DB Consumer templates. Is there any other way to implement an interface without using ATL OLE DB Consumer Template like a simple C++ class for pocket pc 2003?
Also, how to move record sets,execute sql queries and open tables using OLEDB API's?
Slease explain in detail. Suggestions are most welcome.

Hi,
I went through the code. In ADOCE, the following interface is available.
pIADOCERecordset->MoveFirst();
pIADOCERecordset->MovePrevious();
pIADOCERecordset->MoveLast();
I am not able to understand how to move the recordset in OLEDB. Please explain how to move recordset Last,Previous,First and Next like in ADOCE using OLEDB API's.
Is the same interface available in OLEDB?
Please suggest me.
Regards,
AKS

These methods are available from the IRowset::GetNextRows method. Its use is not necessarily direct, that's why I use the Consumer Templates.

hi,
Basically, I am new to SQL Server CE, can you please do let me know what are all the steps I need to follow when I want to open a SQL statement or TABLE with some sort of constraints like cursortype and lock type.
pleas do let me know what are all the steps I have to follow to solve this problem.
suggestions are most welcome.

AKS

I don't have much experience in using raw OLE DB, only through the consumer templates. These can be used with MFC, WTL or with straight API. Please check my article for the info you want (start of thread).

Hi,
To pass cursor type and lock type , which interface I supposed to use and how in OLEDB. I am not able to find proper document for this problem.
please do let me know if you have any idea in this regards.

You can get the OLEDB basics from :
http://home.worldonline.dk/viksoe/dbwrappers.htm[^]
Your Db Admin create code is :
CComPtr<idbdatasourceadmin> dbAdmin;
HRESULT rc = dbAdmin.CoCreateInstance(CLSID_SQLSERVERCE_2_0, NULL, CLSCTX_INPROC_SERVER);

Hello,
Great! Thanks ! I am going through the code. please tell me, what are all the dependency files which i have to include for running the test client ?
Just wanted to know, Will the same code works under pocket pc 2003?
Shall certainly revert back to you if any need arises.

AKS

It's not my code. I don't think it will compile as is under EVC. It is one of the few simple examples out there on how to use OLEDB. You will have to read, understand, and likely rewrite a little to get it to compile for PPC 2002. The same goes for getting it to work for PPC 2003.
I did a project for a client (so can't give out code) where i used the following to get OLEDB to work with EVC3 and PPC2002.
my stdafx.h file starts with :
#define VC_EXTRALEAN
#include <windows.h>
#define OLEDBVER 0x210
#define DBINITCONSTANTS
#define INITGUID
// OLEDB Files:
#include <oledb.h>
#include <oledberr.h>
#include <msdasc.h> // OLE DB Service Component header
#include <msdaguid.h> // OLE DB Root Enumerator
#include <coguid.h>
#include <ssceoledb.h> // SSCE
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <atlbase.h>
#include <afxtempl.h>
#include <afxdtctl.h> // MFC support for Internet Explorer 4 Common Controls
#include <afxdisp.h> // MFC OLE automation classes
#include <afxcmn.h> // MFC support for Windows Common Controls
#include <afxsock.h> // MFC socket extensions
#include <wcesock.h>
and, stdafx.cpp contains :
#pragma comment(lib, "oledb.lib")
and, my list of include directories has :
c:\...\SQLCE\INC
and, my list of lib directories has :
c:\...\SQLCE\LIB\ARM\SA1100
(replace ... with path to SQLCE install directory on desktop computer)

CMK,
Thanks for your reply. Yes that code will not work under PPC 2003.The implementation will not be applicable for SQL Server CE.
Plz,tell me what are all the stpes that i need to follow when i want to create a recordset,open sql and open table. If you have any code sample for these problem, please send it to me via mail. It would be of an immense help for me to understand the flow becuase I am not able to find a good document for oledb on windows ce. For example Windows SQL Server CE supports only three types of cursor types in general and I am not able to find what are all the lock type sql server ce supports and etc., in detail.
Looking for your reply.
Regards,
AKS

All the info about locks and cursors is in the SQLCE doc's.
All the info you need to create/open/exec a cmd against a table is in the code i originally provided a link to :
http://home.worldonline.dk/viksoe/dbwrappers.htm[^]
You will have to read, understand, and port the code to WinCE. With the header and path info i provided this should take a couple hours.
I don't have the time to do all this for you.
Nor can/will i release code developed for a client - sorry.
Good luck,
...cmk
