You've defined UNICODE. This means that CString manages an array of WCHARs, not of chars.
To handle this behaviour-switching between UNICODE being defined and not defined, use the macros in tchar.h. The documentation for each wrapped function shows the equivalent tchar.h name under "Generic-Text Routine Mappings". For strtod, the equivalent API that operates on TCHARs is _tcstod.

Mike,
Thanks. So instead of strtod, I use _tcstod?
I am a VC++ newbie. an example would be great.
thanx.

Hi!!!
I have a pda application that uses a dll that I made.
That dll has some images that i load as an embedded resource, when i run the application, it takes some time t load all images and i can see in the emulator the images loading... What can I do to make the images load at the same time??
Thanks in advance

The best solution I found, when loading a lot of images when the program starts, was to display a splash screen with a progressbar.
That way, the few seconds it taks to load seem to go faster.

I Have two problem to manage Pocket PC 2002 Network Connection :
1st. I have create Bluetooth application and it's work fine when bluetooth is active. But when inactive my application is always error. How can i detect Bluetooth is active or not by software, and also how can i activate bluetooth manually by my software ?
2nd. I try to send data by GPRS, it always succeed when GPRS is active. But when GPRS is inactive it's always error. So how to create software to configure the GPRS connection and connect the GPRS manually without using Net.WebRequest and CMHELPER ?
Thank's for support.

I am a novice to Windows CE so sorry in advance if this is a stupid question.
We just got an Itronix Q200 with WindowsCE 4.2 and I would like to be able to set up a folder on this device as being shared on the network so that a desktop pc can access this folder (via \\IPaddr\sharename) so that an app that runs on the desktop pc can do file transfers with the device. I can ping the device from the desktop pc and can ping the desktop pc from the device so the device is communicating on the network, but I don't know how to set up a share on the device. My app needs this share to do the file transfers.
Is this possible?
Thanks, gary

I'm having problems receiving and making phone calls whilst a GPRS session is active. I'm using third part components to programatically make the RAS connection (in C#), but when a phone call is made or received the connection utility is locked out and cannot make another successful connection until the device is reset. Even manual connections cannot be done until the device is reset. I have tried connecting manually, and when a phone call is made or received the GPRS session is simply suspended, and reactivates when the phone call is over. I have tested several third party components and they all have the same problem. One of them said there was nothing they could do about it as it was a problem with the RAS DLL. Is this true? Is it not possible to programatically create a GPRS connection via the RAS DLL whilst also being compatible with phone usage? Does anyone know a way around this problem?

You should change the SQL collation to SQL_Latin1_General_CP1254_CI_AS.

I use vs.net2003 to write a SmartDevice application on desktopo PC.
But, the vs.net2003 only support IrDa/TCP methods to transfer code from desktop PC to PocketPC. Since the PC didn't has one Irda dongle and I don't want to buy a ethernet card for PPC, how to use USB to transfer code to PocketPC?
Thanks.

There's no need to buy an ethernet card for ppc. The TCP transfer mode connects to the PPC using ActiveSync. You just need to cradle the PPC, and VS.NET2003 will use ActiveSync to transfer your program to PocketPC.

Hello
I am very new to mobile devices. I am attempting to write my first MFC app for a Pocket PC. I have a dialog app created with the wizard and I have added a number of edit controls to the dialog template.
When I use Class Wizard to add variables for the edit controls it says 'There are no data types for this type of control'
Is CEdit not available in MFC on CE?

Yes, it is. You can bind an edit control to either a CEdit or to CString, int, long...

Hello,
I 'm trying to create a simple program that would run like a daemon for PocketPC and I have the eMbedded Visual C++ 4.0 IDE. I choose to create a new project and my options are limited to applications with GUIs, a WinMain() etc. I want to write a very simple unix like non-gui program in C. I don't even need a console. Is there any way to avoid all these windows specific chaos code?
Thanks, Themis

You can start from 'WCE Application' or 'WCE Pocket PC 2003 Application'. On the first page of the wizard, select 'A simple Windows CE application'. This generates a StdAfx.h for common includes and definitions, StdAfx.cpp (which causes precompiled headers to be generated for StdAfx.h) and project.cpp, which contains a WinMain routine.
Pocket PC does not support the C standard main routine. The Windows CE C run-time library does not provide the mainCRTStartup routine that the desktop provides. You should use WinMain instead.
Please be aware that Windows CE only supports a total of 32 concurrent processes - this is a consequence of the single-memory-map design. A number of those process slots are already running at startup time - the device driver host process device.exe, the Graphics Windowing and Events Subsystem gwes.exe, the file system process filesys.exe, and others. CE 4.x and later provide a Services host process for hosting services written as DLLs.
