Hi,all,
Does anyone have some good ideas about derive form CCeSocket in EVC 4.0?
When I try to use the "Insert->new class",when I choose the "class Type" as MFC class, I just cann't find the CCeSocket from the "basic class". So I just write the codes myself. Do you have any decent way to do the same job?
pls tell me. Thank you
Best Wishes,

Hi, all,
I am now using CCeSocket and met the OnReceive() bug: That is, on the server side, for the accepted socket, the OnReceive() never called. I have followed the steps on MS website but still cannot work. On MS website, it said the solving method applies to WinCE 3.0 and lower version. But I am now using WinCE4.2(PocketPC 2003). I don't know how to solve the problem now.
My procedures is as follows: modify the wcesock.h-> in my codes, after the listening socket accept the communication socket, make the latter's m_bConnectCalled = true->rebuild. Is there anything I miss?
Anyone got any good ideas? Thank you so much!
Best Wishes,
HWB

Hey there,,,,,,,,,,
im working on cygnal microcontroller C8051F040 and am trying to interface it with a sonar.t program is ready as far as the interfacing is concerned. but while sending the necessary data over the CAN bus to other nodes, i have a slight problem i.e. i can't store data on flash. Can u help me fined some sites where they have sample programs on CAN & FLASH. is there any kind of a clash between FLASH initialisation & CAN ?? I have configured the CAN bus at 1MBPS.
sonar runs at 115200 baud. and both the uart's run at 115200 baud.
without the FLASH, the data is transferred successfuly to all the other nodes. but with FLASH, the program hangs(if CAN is started.) I also tried disabling CAN before FLASH. doesn't work.. Can nybody help me??
Waitin eagerly....

Hi, I have a program written in eVC++ for a HP1710 PDA running PPC2003. I want my program to automatically run when either a soft or hard reset is done. If I place it in the start up folder it is ok with soft reset but gets wiped when a hard reset is done.
People in other forums have told me to create a folder in the flash memory(permanent memory) called "2577",place my program here and it should run once any reset is done. Also I was advised that if that did not work then create a folder called "0" and place it in that. Both these solutions do not work so I figured someone here might be able to help me.
Oh, the flash storage is called "iPaq File Store";
Thank you
Cush

When u do the hard reset, the DEVICE goes to factory settings. Meaning, it'll be set to the initial configuration which was provided by the vendor(i.e., program stored in the ROM are loaded.) So, you may want to load your program onto ROM than that of RAM. I'm not sure about writing into ROM.
Correct me If I'm wrong and let me know how to do the same.

I'm having a problem with CryptAcquireContext in a .NET Compact Framework application running on the Pocket PC Emulator 2002. On a Pocket PC 2003 Second Edition (a real device) it seems to work fine.
The line of code I'm having a problem with is:
WinApi.CryptAcquireContext(ref hProv, null,
"Microsoft Enhanced Cryptographic Provider v1.0",
1,
0xf0000000);
WinApi is a class that contains the definition of all the PInvoked
methods.
[DllImport("coredll.dll")]
public static extern bool CryptAcquireContext(
ref IntPtr phProv, string pszContainer, string pszProvider,
uint dwProvType, uint dwFlags);
The problem is that on my machine, running the code produces an error 0x80000005
When I tried the code on a collegues machine, her Pocket PC 2002 Emulator produced a differernt error message. She got 0x80090019 on the same function call. I don't understand why there is a difference - both should be set up identically, but I guess there is something different that neither of us is aware of.
Finally, we tried to deploy it to a real Pocket PC device (PPC 2003 Second Edition) and it worked fine.
I need the code to work on PPC 2002 onwards. Does anyone have any idea why I am seeing different results? Or have any idea of how to fix this?

0x80000005 - Invalid pointer.
0x80090019 - The keyset is not defined.
WinCE uses unicode, shouldn't you have L"Microsoft Enhanced Cryptographic Provider v1.0".
Or better yet, use the #defines in crypt i.e. MS_ENHANCED_PROV (MS_ENHANCED_PROV_W).
[EDIT]
Also, for the keyset error you should just create a new one:
bool rc = ::CryptAcquireContextW(&hnd, ct, MS_DEF_RSA_SCHANNEL_PROV_W, PROV_RSA_SCHANNEL, F);
if( !rc ) {
ulong err = GetLastError();
if( err == NTE_BAD_KEYSET ) {
rc = ::CryptAcquireContextW(&hnd, ct, MS_DEF_RSA_SCHANNEL_PROV_W, PROV_RSA_SCHANNEL, F|CRYPT_NEWKEYSET);
if( !rc ) err = GetLastError();
}
}[/EDIT]
[EDIT2]
Ok, Ignore the first EDIT, it's the same as shown in the MSDN docs (which i assume you've seen).
It's also for error 0x80090016 - Keyset does not exist.
From:
http://support.microsoft.com/default.aspx?scid=kb;en-us;238187[^]
NTE_KEYSET_NOT_DEF (0x80090019):
The Crypto Service Provider (CSP) may not be set up correctly. Use of Regsvr32.exe on CSP DLLs (Rsabase.dll or Rsaenh.dll) may fix the problem, depending on the provider being used.
So i would guess that the coding error is 0x80000005, and that her machine doen't get to that point because it's not setup right.

This call(recvfrom) is waiting infinitely and the application never comes to next line.
I'm using UDP sockets. The data has been sent successfully to server. But I'm facing problem while receiving it. I tested on both smartphone emulator and real device(samsung). In both targets, the application is crashing when it reaches this line. Any idea why it's happening?. Your help is greatly appreciated.
i = recvfrom(s1,packetbuffer,sizeof(packetbuffer),0,(SOCKADDR *)&addr,&cbRemoteAddrSize);

Yes he is right. VC++ is quite difficult to USE. Many times 1 line code is .net is replaced with 10 lines code in VC++. I suggest you to learn VB.NET or Embedded vb. According to my experiance VB.net is better for Embedded Development

 Help!!!
Dear some one there...,
Im beginer VB.Net, still learning to create database application in Win CE.Net following this tutor:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnroad/html/road05222002.asp
in my VB.Net I can't found the reference object for System.Data.SqlServerCe.Engine
but I got obeject System.Data.SqlServerCe.SqlCeEngine there, so I have edited line of code from ...SqlServerCe.Engine to be ...SqlServerCe.SqlCeEngine.
Is my step is right?
Build... succeeded, no error.
Then, I have copy "nortwind Mobile.exe" file from "Debug" folder to my PDA, right?
But, when the application executed, I got the error message like this (on the PDA Win CE.Net):
"Error
An unexpected error has occured in Northwind Mobile.exe."
Detail:
"Error
Northwind Mobile.exe
ArgumentException
Could not find resource assembly
...."
Whats wrong? 
Should I have SQL Server CE installed in my PDA Win CE.Net?

You might need the VB Runtime (or the .Net Compact Framework files) installed on your PPC....
Have you tried to deploy it directly to your pocket pc?
Not sure if this will help, but maybe get you moving in the right direction.

I know that this combination now it's not possible.
The standard_sdk for WinCE.net 4.2 works only with evc 4.0 sp2 or higher (sp4).
The sdks available for VS2005 are only windows mobile 5.0 and pocketpc 2003.
Apparently there is no reason why I cannot compile a native application for wince 4.2 with vs2005 even if it seems that vs2005 only supports wince 5.0.
Anyone has faced the same problem ?

Hello!
Is there an existing program that can handle login to remote computer automatically (i.e. with one click) with HP iPAQ? Remote terminal server always requires normal windows login after connecting to remote computer. What I'd like to have, is that to happen automatically just like windows remote desktop connection can be configured.

Using a pc I would use
GetBitmapBits
to get all the bits that make up an image, CE 4 however does not support this
I have tried a load of things to get the bitmap bits
the latest is this
//Get a handle to the screen DC
HDC hdcScreen = CreateDC(_T("DISPLAY"), NULL, NULL, NULL);
//CREATE A COMPATIBLE DC
HDC hdcCompatible = CreateCompatibleDC(hdcScreen);
// Create a compatible bitmap for hdcScreen.
HBITMAP hbmScreen = CreateCompatibleBitmAP(hdcScreen,lBitmap.bmWidth,lBitmap.bmHeight);
//PUT OBJECT IN TO THE DC TO BE POPULATED WITH INFO
SelectObject(hdcCompatible, hbmScreen);
//COPY INFO FROM SCREEN DC TO COMPATIBLE DC
BitBlt(hdcCompatible,0,0,lBitmap.bmWidth,lBitmap.bmHeight,hdcScreen,0,0,SRCCOPY);
So at this point i would expect the hbmScreen to be populated with all the current screen information, the next thing i need to do is see all that info in a bitmap i thought somthing like this might work but no
BITMAP* bitmap = (BITMAP*)hbmScreen;
I thought the above would allow me to get the bitmapbits as below
bitmap.bmBits
but I get bugger all back, this is begining to get on my tits, so if anyone knows any way of getting the raw data and can post up the example code or even show me where i am going wrong I would be oh so happy
