Device Power Management in WM

Dear сolleagues and development guru!
I have some stopper in Power Management. I hope somebody will help me to understand.
Technologies: C#, .NET 3.5
The main point of application:
Make beep periodically.
Main problem is:
When PocketPC in active mode application running correct, but when PocketPC went to sleep mode it does not make a beep. As I understood speaker is turned off in sleep mode (like all other devices in PocketPC).
Question:
How can I turn on speaker in sleep mode?
Simply what I need is turn on speaker, make beep and back speaker to previous mode without wake up all device.
I tried code like this:
Code:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Media;
using System.Threading;
using System.Runtime.InteropServices;
namespace TestProject
{
static class Program
{
public const int POWER_NAME = 0x00000001;
public enum DevicePowerState : int
{
Unspecified = -1,
D0 = 0,
D1,
D2,
D3,
D4,
}
[DllImport("coredll.dll", SetLastError = true)]
public static extern int SetDevicePower(
string pvDevice,
int dwDeviceFlags,
DevicePowerState DeviceState
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr SetPowerRequirement(
string device,
DevicePowerState state,
uint deviceFlags,
IntPtr systemState,
ulong stateFlags
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern int ReleasePowerRequirement(IntPtr handle);
[MTAThread]
static void Main()
{
MessageBox.Show("Application is running...", "Confirmation", MessageBoxButtons.OK, MessageBoxIcon.Asterisk,MessageBoxDefaultButton.Button1);
string deviceName = "WAV1:"; // speaker
for (; ; )
{
// set D0 power value
IntPtr handle = SetPowerRequirement(deviceName, DevicePowerState.D0, 1, IntPtr.Zero, 0);
// make a beep
SystemSounds.Beep.Play();
// set default power value
ReleasePowerRequirement(handle);
Thread.Sleep(10000);
}
}
}
}
And like this:
Code:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Media;
using System.Threading;
using System.Runtime.InteropServices;
namespace TestProject
{
static class Program
{
public const int POWER_NAME = 0x00000001;
public enum DevicePowerState : int
{
Unspecified = -1,
D0 = 0,
D1,
D2,
D3,
D4,
}
[DllImport("coredll.dll", SetLastError = true)]
public static extern int SetDevicePower(
string pvDevice,
int dwDeviceFlags,
DevicePowerState DeviceState
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr SetPowerRequirement(
string device,
DevicePowerState state,
uint deviceFlags,
IntPtr systemState,
ulong stateFlags
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern int ReleasePowerRequirement(IntPtr handle);
[MTAThread]
static void Main()
{
MessageBox.Show("Application is running...", "Confirmation", MessageBoxButtons.OK, MessageBoxIcon.Asterisk,MessageBoxDefaultButton.Button1);
string deviceName = "WAV1:"; // speaker
int resDevicePowerOn = SetDevicePower(deviceName, POWER_NAME, DevicePowerState.D0);
for (; ; )
{
// make a beep
SystemSounds.Beep.Play();
Thread.Sleep(10000);
}
}
}
}
But any of these codes does not work - there are no beep in sleep mode.

Hi, I just happened to find an article from codeproject.
You may want to take a look at it.
http://www.codeproject.com/KB/mobile/WiMoPower1.aspx
I think what you need is cerunappattime.

It seems you are enabling the audio device to run in low-power mode, but you are not actually telling the CPU to keep running ("unattended mode").
Lookup PowerPolicyNotify, specifically PPN_UNATTENDEDMODE.
You may also need to periodically call SHIdleTimerResetEx and/or SystemIdleTimerReset to keep the device active in unattended mode or it will still truely suspend.

Prevent the system enter sleep mode
The system will stop all activitis when the system enter sleep mode.So you must prevent the system enter sleep mode.
The system sleep mode：
on -> unattended -> suspend
You can run：
on -> unattended -> resuming
my code：time up is system on

[Q] [.net cf]Loopback

Hey guys
I'm developing a little webserver for WM with the .net cf. it's easy and works fine as long as I don't try to access it from the same device it's running on. Nothing works: localhost,127.0.0.1 or even if I'm connected to a wifi network and I use this IP. Has anyone the solution for this issue?
ta you
a yeah I use the TcpListener-Class and I implemted some simple HTTP.

Code
Hey guys
Noone has an idea??
Here is the code which I use to setup the HttpListener and answer connections.

}
private void menuItem1_Click(object sender, EventArgs e)
{

}
}
}
The user can choose the IPEndPoint(constructor), which the server will be bound to, in a prevouis form:
Code:
foreach (IPAddress ip in Dns.GetHostEntry(Dns.GetHostName()).AddressList)
{
item = new SensePanelRadioItem(ip.ToString());
item.PrimaryText = ip.ToString();
item.SecondaryText = ip.AddressFamily.ToString();
item.Tag = ChoosedIp = ip;
item.OnStatusChanged += new SensePanelRadioItem.StatusEventHandler(item_OnStatusChanged);
IPList.AddItem(item);
}
So the user can choose between IPs I got from the DNS (e.g. 127.0.0.1, 192.168.0.1) and type a free (valid) port number (eg. 80, 8080, 8888)
Thanks for Your help!!

Still no answer...
I will post my experiences with this issue as long as I solved it - like small blog. Maybe some of you have the same problem...
I found another strange thing:
I'm able to connect to my Server from a TcpClient from another self-written App (own exectuable, different AppDomain):
Code:
void test()
{
Action<string> setText = new Action<string>(setTestText);
try
{
this.Invoke(setText, "Connect...");
TcpClient client = new TcpClient();
client.Connect(local);
this.Invoke(setText, "Connected...");
NetworkStream stream = client.GetStream();
StreamWriter writer = new StreamWriter(stream);
StreamReader reader = new StreamReader(stream);
writer.WriteLine();
writer.Flush();
this.Invoke(setText, "Read answer");
string buffer = reader.ReadToEnd();
this.Invoke(setText, "Test succeeded");
testing = false;
}
catch
{
this.Invoke(setText, "Test failed");
}
}
And I got a the right answer as well. It's strange, really strange that the browsers (IE,Opera etc.) can't loopback to it?

MAPIdotnet and binary message body

Best all,
A while ago I tried to make a simple application which can export all my smses and mmses to my local database server. It runs quite smoothly but I can't manage to get the correct mms body data. It seems that about 5% of the exported body data(for example a sent picture in jpeg format) is different from the original jpeg picture/body data: the exported picture data can't be viewed, it is corrupt.
I suspect the method of exporting the data must be changed from string to binary, but I don't know exactly how to proceed.
I'm using C# 2008 in combination with the MAPIdotnet library, and my target device is a HTC HD Mini with Windows Mobile 6.5 professional.
The part of my code where it's going wrong:
Code:
ASCIIEncoding asen = new ASCIIEncoding();
byte[] ba = asen.GetBytes(s);
bw.Write(ba);
bw.Close();
fs.Close();
if (messages[msgID].Body != null)
{
FileStream fs2 = File.Create("\\Opslagkaart\\Debug\\body_" + Convert.ToString(msgID) + ".dat");
BinaryWriter bw2 = new BinaryWriter(fs2);
System.Text.UnicodeEncoding enc = new System.Text.UnicodeEncoding();
byte[] file = enc.GetBytes(messages[msgID].Body);
//bw2.Write(messages[msgID].Body);
bw2.Write(file);
bw2.Close();
fs2.Close();
}
In combination with MAPIdotnet's code:
Code:
public string Body
{
get
{
IStreamChar s = (IStreamChar)this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0);
if (s == null)
return "";
IntPtr p = Marshal.AllocHGlobal(4);
char[] b = new char[3];
StringBuilder str = new StringBuilder();
int c, len = b.Length * 2;
do
{
s.Read(b, len, p);
c = Marshal.ReadInt32(p);
str.Append(new string(b, 0, c / 2));
}
while (c >= len);
Marshal.FreeHGlobal(p);
return str.ToString();
}
}
Can somebody give a hint of how to proceed?
Thanks,

I suddenly got some more inspiration and, with help from google, I've managed to correctly retrieve the binary jpeg attachments of two of my mmses.
The code part of my program:
Code:
//if (messages[msgID].BodyBinary.Length>0)
//{
FileStream fs2 = File.Create("\\Opslagkaart\\Debug\\body_" + Convert.ToString(msgID) + ".dat");
BinaryWriter bw2 = new BinaryWriter(fs2);
bw2.Write(messages[msgID].BodyBinary);
bw2.Close();
fs2.Close();
//}
The code part of the customized MAPIdotnet:
Code:
private static IntPtr ReadBuffer;
static int Read(OpenNETCF.Runtime.InteropServices.ComTypes.IStream strm, byte[] buffer)
{
if (ReadBuffer == IntPtr.Zero) ReadBuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(typeof(int)));
try
{
strm.Read(buffer, buffer.Length, ReadBuffer);
}
catch (NullReferenceException e)
{
//do nothing
}
return Marshal.ReadInt32(ReadBuffer);
}
public byte[] BodyBinary
{
get
{
int buffsize = 1024*1024*2; /* If mms body is bigger than 2MB we have a problem here */
byte[] buffer = new byte[buffsize];
Read(this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0), buffer);
byte[] data = buffer;//ms.ToArray();
Marshal.FreeCoTaskMem(ReadBuffer);
return data;
}
}
But now ALL bodies are saved as 2MB files.. including the empty ones from for example a sms. And not all mms bodies are of the max size of 2mb. My carrier/phone supports up to 1MB. Perhaps I need to get some 'dynamic size' buffer instead of the fixed one. Does anyone have an idea on how to determine the size of the
this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0)
Click to expand...
Click to collapse
stream ?

I've solved all my problems by means of the following code (for mapidotnet):
Code:
private static IntPtr ReadBuffer;
static int Read(OpenNETCF.Runtime.InteropServices.ComTypes.IStream strm, byte[] buffer)
{
int returnvalue = 0;
if (ReadBuffer == IntPtr.Zero) ReadBuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(typeof(int)));
try
{
strm.Read(buffer, buffer.Length, ReadBuffer);
returnvalue = Marshal.ReadInt32(ReadBuffer);
}
catch (NullReferenceException e)
{
returnvalue = 0;
}
return returnvalue;
}
public byte[] BodyBinary
{
get
{
int newdatasize = 0;
int buffsize = 1024*1024*3; /* If mms body is bigger than 3MB we have a problem here */
byte[] buffer = new byte[buffsize];
newdatasize = Read(this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0), buffer);
if (newdatasize < 0) { newdatasize = 0; }
byte[] data = new byte[newdatasize];
Buffer.BlockCopy(buffer, 0, data, 0, newdatasize);
Marshal.FreeCoTaskMem(ReadBuffer);
return data;
}
}
Now all is working fine and the exported files are of their own real size. I'm sure the above code can be optimized but it's working good now.

oh wait, isRooted doesn't take any arguments and you're trying to hook isRooted with a boolean argument, which would be a different method
return values are called result here (getResult, setResult.) args is only for arguments

Oh thx

Code:
06-17 22:21:05.373: E/Xposed(30470): java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference
06-17 22:21:05.373: E/Xposed(30470): at de.bozja.hrh.Hidder$1.beforeHookedMethod(Hidder.java:22)
Error why?
class
Code:
findAndHookMethod("com.example.RootCheck", lpparam.classLoader, "isRooted", new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult(); //Error on this line
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult();
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
});

beforeHookedMethod is called before the method is executed, so there can't be any result. so it's null

Just setresult to false in beforehooked dont add extra junk
And dont hook method afterhook no need before will do what u need

oh wait, isRooted doesn't take any arguments and you're trying to hook isRooted with a boolean argument, which would be a different method
return values are called result here (getResult, setResult.) args is only for arguments

i am also facing the same issue today when trying to hook some certain method that doesnt take in any argument. And i really didnt get the answer you gave. Could you be more elaborate please?

that was a long time. necrobumping from Google?
I think I meant to use param.setResult instead of param.args[0] to set the return value

this is the method i want to hook. I want it to return false
public boolean vpn() {
try {
Iterator it = Collections.list(NetworkInterface.getNetworkInterfaces()).iterator();
String str = "";
do {
if (!it.hasNext()) {
return false;
}
NetworkInterface networkInterface = (NetworkInterface) it.next();
if (networkInterface.isUp()) {
str = networkInterface.getName();
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("IFACE NAME: ");
stringBuilder.append(str);
Log.d("DEBUG", stringBuilder.toString());
if (str.contains("tun") || str.contains("ppp")) {
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
}
} while (!str.contains("pptp"));
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
return true;
} catch (SocketException e) {
e.printStackTrace();
}
}
and this is my kotlin class
package app.devzeus.yesvpn.hook
import de.robv.android.xposed.IXposedHookLoadPackage
import de.robv.android.xposed.XC_MethodHook
import de.robv.android.xposed.XposedHelpers
import de.robv.android.xposed.callbacks.XC_LoadPackage
class hook: IXposedHookLoadPackage {
override fun handleLoadPackage(lpparam: XC_LoadPackage.LoadPackageParam?) {
val pakage = "com.eclipse.gamonyapp"
val className = "com.eclipse.gamonyapp.Fragments.OffersFragment"
val method = "vpn"
if (lpparam?.packageName == pakage){
XposedHelpers.findAndHookMethod(className, lpparam.classLoader, method, object: XC_MethodHook(){
override fun beforeHookedMethod(param: MethodHookParam?) {
super.beforeHookedMethod(param)
param?.result = false
}
})
}
}
}
am i doing it wrong? it still doesnt work. The class and method locations are correct

this should be a separate thread imo
XC_MethodHook | Xposed Framework API
api.xposed.info
in Java there would be no need for the super call and the syntax is .setResult, but I'm not sure in Kotlin

about the .setResult(false) the compiler suggests .result = false
