July2011 Optional Updates Are On ECE For XPe SP3, Standard 2009 and Standard 7

July2011 Optional Updates Are On ECE For XPe SP3, Standard 2009 and Standard 7: "

*UPDATED 8/10/11 - Added link for Standard 7*

The July 2011 Optional Updates are now available on the ECE site for Windows® Embedded Standard 2009, Microsoft® Windows® XP Service Pack 3 and Windows Embedded Standard 7. Fixes include:

The list below applies to XP Embedded SP3 and Windows Embedded Standard 2009

KB2540135 - This update fixes the following issue

• 
  

  This update fixes an issue where the File Based Write Filter (FBWF) Provider might crash while getting FbwfCacheDetail instances, after seven or more files have been added to or changed in the FBWF overlay, resulting in the FbwfCacheDetail instances containing corrupted file names in the FileName property.

  
  

The list below applies to XP Embedded SP3, Windows Embedded Standard 2009 and Windows Embedded Standard 7 SP1

• 
  

  KB2539566 – This update fixes the following issues

  
  




• The Enhanced Write Filter Provider will crash if all EWF volumes have their Overlays disabled and the user tries to subscribe to a EwfOverlayStoreConfiguration event query. Until the new EWF Provider instance is created, all other commands will fail. Expected return code in this case would be 0x80070057 = ERROR_INVALID_PARAMETER. If a crash has occurred, the return code is 0x80041004 = WBEM_E_PROVIDER_FAILURE.


• 
  

  The event notification threshold values in EWF are inverted.

  
  

The list below applies to Windows Embedded Standard 7 SP1 and Windows Embedded Standard 7

KB2570814 (Windows Embedded Standard 7 SP1 only)- This update fixes the following issues:

• FBWFAPI by design does not allow multiple commands to be executed at the same time and it returns a clear error. The fix introduces locks in the File Based Write Filter (FBWF) Provider’s FBWFAPI calls, and all parallel requests will get served without errors returned.


• The cache detail (changed or added files in the FBWF cache) file can be flushed from the cache in the timespan between FbwfCacheDetail instantiation and property data gathering, which results in property data gathering returning an unexpected error.


• The event notification threshold values in FBWF are inverted.

KB2573437- This update fixes the following issue:

• The runtime to be incorrectly configured as “SERVICE_DEMAND_START”. Specifically, when the “Enhanced Write Filter with HORM” package is added to an image with one or more protected volumes that are configured with default settings for “DisableDefragSvc”, the runtime should be configured to disable Auto Defragmentation service (DefragSvc), by setting the “DefragSvc” service to “SERVICE_DISABLED”.


• This update also fixes the following issue for Windows Embedded Standard 7:




• An issue that causes EWF to be configured on all existing volumes on the system. Specifically, when the “Enhanced Write Filter with HORM” package is added to an image with one or more protected volumes that are configured with default settings for “EWFMode”. To correctly install this update, this KB must be applied to a Distribution Share prior to building and subsequent deployment of an image. Note that this fix was incorporated into Windows Embedded Standard SP1 when it shipped.

KB2573449 - This update fixes the following issues:

• Extends EWF support for storage devices that use TRIM. Without this update, TRIM commands sent by the Filesystem will bypass EWF and violate write filtering guarantees provided by EWF.


• This update also fixes the following issue for Windows Embedded Standard 7:




• A fatal registry corruption or BlueScreen (STOP error) can occur when EWF is enabled and “ewfmgr /all /commitanddisable” is executed followed by a reboot. Note that this fix was incorporated into Windows Embedded Standard SP1 when it shipped.

Driver wrapper for C#

From .NET Compact Framework, there is no API allowing access to the driver interfaces, as the main reason of the framework existance is to be able to run on whatever hardware an application without having to recompile it, this by the usage of the CLR (Common Language Runtime).

But developper working on embedded systems usually have to access those drivers that are specific to the platform. So in that case they need an access to the native APIs.

Identify the needs
Before getting access to the driver from C# you have to identify the APIs that have to be mapped from native to managed environment. Accessing a driver from native code is performed using the following APIs :
- CreateFile : in order to open a driver instance
- CloseHandle : to close the opened instance
- ReadFile : read data from the stream
- WriteFile : write data into the stream
- Seek : move data pointer in the stream
- DeviceIoControl : to perform driver specific actions with the usage of the CTL_CODE macro for commands IDs

Map the native API
In order to map the native API into C#, the usage of the interop services is required.
Note : you can find native API mapping from pinvoke.net (http://www.pinvoke.net/) website.

Create a driver class
We have to define the Driver class that will handle all the wrapping actions for us.

using System;
using System.Runtime.InteropServices;

namespace Adeneo_Embedded
{
   public class Driver
   {
   }
}

Map the mandatory native functions

• CreateFile function

// This function creates, opens, or truncates a file, communications
// resource, disk device, or console. It returns a handle that can be
// used to access the object. It can also open and return a handle to
// a directory.
[DllImport ("coredll.dll")]
private static extern int CreateFile(
 string lpFileName,
 int dwDesiredAccess,
 int dwShareMode,
 int lpSecurityAttributes,
 int dwCreationDisposition,
 int dwFlagsAndAttributes,
 int hTemplateFile);

• CloseHandle function

// This function closes an open object handle
[DllImport ("coredll.dll")]
private static extern int CloseHandle(int hObject);

• ReadFile function

// This function reads data from a file, starting at the position indicated
// by the file pointer. After the read operation has been completed, the
// file pointer is adjusted by the number of bytes actually read.
[DllImport ("coredll.dll")]
private static extern int ReadFile(
 int hFile,
 byte[] lpBuffer,
 int nNumberOfBytesToRead,
 ref int lpNumberOfBytesRead,
 ref OVERLAPPED lpOverlapped);

• WriteFile function

// This function writes data to a file. WriteFile starts writing data to
// the file at the position indicated by the file pointer. After the write
// operation has been completed, the file pointer is adjusted by the number
// of bytes actually written.
[DllImport ("coredll.dll")]
private static extern int WriteFile(
 int hFile,
 byte[] lpBuffer,
 int nNumberOfBytesToWrite,
 ref int lpNumberOfBytesWritten,
 ref OVERLAPPED lpOverlapped);

• DeviceIoControl function

// This function sends an IOCTL directly to a specified device driver,
// causing the corresponding device to perform the specified operation.
[DllImport ("coredll.dll")]
private static extern int DeviceIoControl(
 int hFile,
 uint dwIoControlCode,
 byte[] lpInBuffer,
 uint nInBufferSize,
 byte[] lpOutBuffer,
 uint nOutBufferSize,
 ref uint lpBytesReturned,
 ref OVERLAPPED lpOverlapped);

Redefine the CTL_CODE macro
When driver developper is implementing the driver IoControls and when the application developper want to execute this command, then both should refer to the same identifier. To get a unique identifier for a driver command, the CTL_CODE macro is used.

//
// Macro definition for defining IOCTL and FSCTL function control codes.  Note
// that function codes 0-2047 are reserved for Microsoft Corporation, and
// 2048-4095 are reserved for customers.
//

public uint CTL_CODE(uint DeviceType, uint Function, uint Method, uint Access )
{
}

Redefine the constant values
CreateFile, DeviceIoControl, and CTL_CODE code is using constant that also have to be redefined in our driver class.

#region "constants"

#endregion          // read data from the driver

This is it, now we have a class that really simplify the access to the drivers.

Driver myI2CDriver = new Driver();
myI2CDriver.Open("I2C1:");
…
myI2CDriver.Close();

WEC 7 : Build Solution performing a Buid & Sysgen

Using the CTP version of Windows Embedded Compact 7 available from the Microsoft Connect website (http://connect.microsoft.com), you will face a unexpected behavior of the development environment.

When building a solution using the Build menu, you will launch a Build and Sysgen (blddemo.bat) command instead of a Sysgen (blddemo -q) as it was the case in the previous version. This Build and Sysgen action is rebuilding the complete content of the $(_WINCEROOT)\Public folder, that is usually useful when you are making modification into this folder. In the case of the build of a runtime image, this step is not required and is increasing the build time.
As this action is not required, it is useful to avoid the execution of a such action. This can be done by modifying the blddemo.bat file located in $(_WINCEROOT)\PUBLIC\COMMON\OAK\MISC and adding in the first lines :

If "%1"=="" goto :EOF
