Hi,

I have not found an answer yet to this, I will spend some more time on this and hopefully come up with a solution.

Thanks

Hi, pauldiston! Did you ever figure out an answer to your code question? We do have a few technical experts here - could you have stumped them? Anyone? Thanks!

Hi,

I am trying to extract the Wi-Fi settings from my Windows Mobile 6 device using the following XML :-

<wap-provisioningdoc>
<characteristic-query type="Wi-Fi" recursive="true"/>
</wap-provisioningdoc>

http://msdn.microsoft.com/en-us/library/aa456174.aspx

And the following C# code :-

string xml = ReadXMLFile(@"\Temp\WPA.xml");

string output = ConfigWrapper.ProcessXml(xml, ConfigFlag.Metadata);

using System;

using System.Runtime.InteropServices;

namespace WPAConfigTester

{

public enum ConfigFlag : uint

{

/// <summary>

/// The configuration management service and the

/// Configuration Service Providers (CSPs) process

/// the input data.

/// </summary>

Process = 1,

/// <summary>

/// The configuration management service gathers

/// and returns metadata for any XML parm elements

/// it encounters.

/// </summary>

Metadata = 2

}

/// <summary>

/// The code was taken directly from

/// http://www.smartphonethoughts.com/articles.php?action=expand,4397

/// </summary>

public class ConfigWrapper

{

[DllImport("aygshell.dll")]

private extern static UInt32 DMProcessConfigXML(string xmlIn, UInt32 flag, out IntPtr xmlOutPtr);

[DllImport("coredll.dll")]

private extern static IntPtr LocalFree(IntPtr hMem);

public static string ProcessXml(string xml)

{

return ProcessXml(xml, ConfigFlag.Process);

}

/// <summary>

/// This function wraps acts as a managed interface to the

/// DMProcessConfigXML in Pocket PC 2003+ and Smartphone 2002+

/// The DMProcessConfigXML function grants remote access to the

/// </param>

/// <param name="flag">

/// </param>

/// <returns>

/// String of valid XML containing the result of this operation

/// </returns>

public static string ProcessXml(string xml, ConfigFlag flag)

{

IntPtr xmlOutPtr;

string xmlOutStr;

long result;

result = DMProcessConfigXML(xml, (uint)flag, out xmlOutPtr);

// marshal the output string

xmlOutStr = Marshal.PtrToStringUni(xmlOutPtr);

// free the memory allocated by the API

LocalFree(xmlOutPtr);

// throw an exception if an error code was returned

if (result != 0)

{

throw new ArgumentException(String.Format("DMProcessConfigXML returned error code {0}", result),

xml);

}

return xmlOutStr;

}

However each time I run this code all I get back is whatever XML I pass into the ProcessXml method.

Please could someone shed some light on this.

Thanks in advance.

Great job CRC!!

EAP is configured by the "EAPType" XML element.

The allowed values are:
13 - Smart Card or Certificate (EAP-TLS)
25 (default) - Protected EAP (PEAP)

That being said, I haven't found a way to supply a username and password via XML - someone else may have that information however...

Welcome Paul.

Though I shall have to leave the answer to David or CRC or one of our other developer contributers.

Hi,

I was wondering whether it is possible via the XML to provision the device in such a way that the config can be as follows :-

Encryption - WPA TKIP

EAP Type - PEAP-MSCHAP

Credentials - Username and Password

Thanks in advance.

Awesome,

Wifi is a handy one to have too.

Configuring WiFi connectivity via cab file

Some of this was copy and pasted from DavidC's tutorial on configuring exchange via a cab file to standardise things in this forum.

Wifi connectivity on supported Windows Mobile 5, 6 & 6.1 devices can use the CSP provided to configure the device automatically.

The XML:

There are a couple of values that you will want to change to suit your network environment.

Firstly, DestID. This tells the device if this network is "Work Network" or "The Internet". The possible values are {436EF144-B4FB-4863-A041-8F905A62C572 for The Internet, or {A1182988-0D73-439e-87AD-2A5B369F808B} for Work Network.

Encryption can be one of the following values to suit your network:

0 = Encrypt using 802.11 wired equivalent privacy (WEP) key.
1 = No encryption.
4 = Encrypt using Temporal Key Integrity Protocol (TKIP) sequence counters.
6 = Encrypt using Advanced Encryption Standard (AES).

Authentication can be any of the following:

0 = Open Network
1 = Shared Network
3 = WPA
4 = WPA-PSK
5 = WPA-NONE
6 = WPA2
7 = WPA2-PSK

Put this into NOTEPAD. We cannot have any text formatting on this, so word is out of the question, just straight notepad.
Save this as _setup.xml from the notepad save as menu. If you can't save as xml, then change the file extension after you save it as a .txt.

The name of the file - _setup.xml is important.

You can change around the below instructions, but this should make it easier for people who are new to compiling cabs

Save your _setup.xml to a directory called C:\Cabs\ on your computer.
Now open up a command prompt window Start>Run>cmd.
Type cd C:\Cabs in the command prompt window
Type MakeCAB.exe /D COMPRESS=OFF _setup.xml Wifi.cab

Now you will have an Wifi.cab file in your C:\Cabs directory.
Launch this on your device and the settings will be provisioned.
