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

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

}
}
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?
Hello,
i started to wrote my first WO7 applicatin.
I got following code:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
...
}
...
}
My Problem is that the content of the Button doesn't change to "Calculating". Even my Progressbar:
Code:
private void PbStep()
{
if (Pb1.Value == Pb1.Maximum)
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
else
{
Pb1.Value = Pb1.Value + 1;
}
}
It is wrapped in s loop, and the bar begins with 0 and then switsch to 100%, but i cant see the steps between.
I think i need a refresh command. in visual basic it is Me.Update();.
I tried many codes from google, but nothing helped. I hope some1 can help me.
many thank
Try
Code:
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});
i did already try this. but now when i press the button, while calculation nothing happens, and after the calculation is finished, the button content changes to "calculating" and don't changes back to "start".
so i put the code in both parts and now i got the same as before. the button did not change its content
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "";
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});
Pb1.Value = 0.0;
Pb1.Maximum = Max;
DateTime StartZeit = DateTime.Now;
for (int i = 0; i < Pb1.Maximum; i++)
{
PbStep();//Count Up PorgressBar
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Start";
});
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
But thank you for your help. any other ideas?
you really need to be looking at a background thread (background worker control may allow you do do this)
any tight loop like that will freeze the UI until the loop has finished
in the 'old days' a doevents within the loop itself would have been suffice but this is not good practice
HTH
Try this one, it does what you've trying to implement but using a correct way:
Code:
using System.Windows.Threading;
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(100);
timer.Tick += (_, __) =>
{
// Here is replacement of your PbStep()
Pb1.Value++;
};
timer.Start();
}
i got it now this way:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "Duration: Calculating...";
BtnStart.Content = "Wait";
DateTime StartZeit = DateTime.Now;
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(1);
timer.Tick += (_, __) =>
{
for (int i = 0; i < Pb1.Maximum; i++)
{
Pb1.Value++;
}
timer.Stop();
LblDuration.Text = "Duration: " + (DateTime.Now - StartZeit).ToString();
BtnStart.Content = "Start";
};
timer.Start();
}
It is half working. When i press Start, the button changes its content imediatly and after finishing the loop it return to its default content.
now i got 2 problems:
1. the progressbar isnt smooth jet
and the bigger one:
2. i wanted to create a benchmark programm an measure how long it takes to count a progressbar from 0 to 1million. now with the timer i dont have the real cpu speed because it is always waiting for the timer to tick. so the benchmark is sensless
@ cameronm:
I know the DoEvent command from other languages, but i wans able to use this in c#. i mainly programm in visual basic, cause this seems to be easy (In this case i would use Me.Update). I have heard from the Background worker, but never tried it. Maybe this can help.
I will do some google search and try to use the Background worker. I'll post again if i got new code
Thanks you all !
hello again
im now that far:
Code:
public partial class MainPage : PhoneApplicationPage

{
this.LblStatus.Text = "Canceled!";
}
else if (!(e.Error == null))
{
this.LblStatus.Text = ("Error: " + e.Error.Message);
}
else
{
this.LblStatus.Text = "Done!";
}
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
In the DoWork Function i receive an error when i try to set a variable like int i=0.
The Failure:UnauthorizedAccessException: Invalid cross-thread access
i followed this instruction: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
but there they did the same. why did i have the error?

The exception you've got show exactly what's wrong: you are trying to access GUI thread variables from another (BackgroundWorker) thread.
Use Dispatcher.Invoke as I recommended to you a few posts above.
thank you sensboston. id dont understand why, because i just have one bgworker, but now it works
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
if (bw.IsBusy != true)
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
Pb1.Value = 0.0;
Pb1.Maximum = Max;
bw.RunWorkerAsync();
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
DateTime StartZeit = DateTime.Now;
Dispatcher.BeginInvoke(() =>
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
if ((worker.CancellationPending == true)) //Abbruchbedingung
{
e.Cancel = true;
break;
}
else //Progressbedingung
{
Pb1.Value = Pb1.Value + 1;
//PbStep();
}
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
BtnStart.Content = "Start";
});
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
Just my progressbar isnt running fluently. still just 0% (before calc) or 100% (after calc) and no steps between

It's simple, dear Watson: your code updating progress bar too fast, without delays needed for GUI updates

yep agree with this .. what you are actually doing in the loop is not enough for you to acutally see the progressbar update .. fast little things these phones of ours
yeah, this was the first i tryed, before posting in this forum.
delay() did not work in c#.
Application.DoEvents() should work if i can believe google, but visual studio says there is no definition for doevents().
So i used
Code:
Pb1.Value++;
System.Threading.Thread.Sleep(1);
after each progressbar.value++, but this either didnt work...
what is the secret?

1 millisecond will not be enough to slow it down either
Maybe try 1000 instead ..
something else i thought of too ..
you may want to think about your design
If a progress bar is going to just flash up and complete as what you are doing is too fast .. you need to think 'is a progress bar the right control to use'
if you are going to increase the amount of work your background thread is going to do then I would say keep the progress bar
If the background thread is going to be this quick always .. then maybe a label saying 'please wait' ... and then hide the label when done .. or something similar
i tried with 1000 ms but this progress bar isnt running.
@cameronm: i want to create a "benchmark app" where the cpu counts the progressbar to 1million and measures the time. the time measuring is working correctly. i just want to get a nice GUI with a running bar, like it runs when you download and install apps from the market.
i was very long googling and found commands like progressbar.PerfomStep(); like described here http://www.java2s.com/Code/CSharp/GUI-Windows-Form/ProgressBarinC.htm
this is also c#, but i cant perfom this command. did i miss some assembly, headers or so? or is it because im doint a windows phone form and that there are less command than in a normal windows application?
You want to make a Benchmark app and you actually used :System.Threading.Thread.Sleep(*int)...!
This is not Benchmarking.
Background Worker like any other ThreadTypeClass should report it's progress via the BackgroundWorker_ProgressChanged_Event(..args).
Inside the Event either u PerformStep() either you implement your own code logic.
If even after this the worker fills instanly like "cameronm" said above then consider making the backgroundworker's Job a bit heavier or leave the progressBar and even the seperated background thread Idea cause it is not Needed.
yes, i am not luck with using a sleep command
PerformStep() is not accepted by the compiler
so you mean just counting up is to "easy". what progress could be "heavier". now i understand what cameronm meant^^
in the evening i will try more difficult calculations like sqare and multiplication of integers. would that be heavy enough?
Typing from LG quantum
Try this: make your calculations in a for loop 1-100..at each loop make progressbar.value++ .
You should be calling ReportProgress and then updating the Progress Bar in the Progress Changed function.
See: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
@PG2G
the link you posted was exactly the source where i learned to implement the bw_worker. but with the command you told me i got an failure in the marked line (see source code comment). It says: InvalidOperationException: Operation has already been completed.
Code:
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
double a, b, c;
DateTime StartZeit = DateTime.Now;
Dispatcher.BeginInvoke(() =>
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum/100; i++)
{
if ((worker.CancellationPending == true))
{
e.Cancel = true;
break;
}
else
{
for (int m = 0; m < 10; m++)
{
a = 3547.23; //double
b = 2354.15; //double
c = (a * b) * (a * a * b);
}
Pb1.Value++;//PbStep();
worker.ReportProgress((i * 10)); //Failure here//
}

@Freeboss
i tried it with your loop and a double calculation but it didnt work...
im going crazy, in vb i can do this in 10 minutes^^
Hey Guys..
I have a problem with my xposed module.
I will a class to boolean false not true if rooted device..
Code:
public static boolean isRooted()
This to return false if rooted device..
Code:

Xposed say me nosuchmethoderror com.example.utils.RootCheck#isRooted(boolean)..
Can help me..
Thanks
Sorry for my bad English i m a german.
what class is it, is it your own?
are you filtering by package name?
Is not my own class..
From another Application..
This is the class. i have decoded.
I want replace "public static final String" , public static boolean isRooted() to ever false and private static boolean a(String str) to ever false..
can help me?
Code:
public final class RootCheck {
public static final String VALUE_DEVICE_FLAG_SU = "su";
public static final String VALUE_DEVICE_FLAG_SUPER_USER_APK = "superuser.apk";
public static final String VALUE_DEVICE_FLAG_TEST_KEYS = "testkeys";
private RootCheck() {
}
public static boolean isRooted() {
BuildConfig.IS_PROD.booleanValue();
return false;
}
public static Object[] getFlags() {
int i;
int i2;
List arrayList;
Object[] objArr;
int i3 = 1;
String str = Build.TAGS;
if (str == null || !str.contains("test-keys")) {
i = 0;
} else {
i = 1;
}
try {
if (new File("/system/app/Superuser.apk").exists()) {
i2 = 1;
if (!(a("/system/xbin/which su") || a("/system/bin/which su") || a("which su"))) {
i3 = 0;
}
arrayList = new ArrayList();
if (i3 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SU);
}
if (i2 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SUPER_USER_APK);
}
if (i != 0) {
arrayList.add(VALUE_DEVICE_FLAG_TEST_KEYS);
}
objArr = new Object[0];
if (arrayList.isEmpty()) {
return arrayList.toArray(objArr);
}
return objArr;
}
} catch (Exception e) {
}
i2 = 0;
i3 = 0;
arrayList = new ArrayList();
if (i3 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SU);
}
if (i2 != 0) {
arrayList.add(VALUE_DEVICE_FLAG_SUPER_USER_APK);
}
if (i != 0) {
arrayList.add(VALUE_DEVICE_FLAG_TEST_KEYS);
}
objArr = new Object[0];
if (arrayList.isEmpty()) {
return objArr;
}
return arrayList.toArray(objArr);
}
private static boolean a(String str) {
try {
Runtime.getRuntime().exec(str);
return true;
} catch (Exception e) {
return false;
}
}
}
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

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
I'm trying to get the TextView of the following method, but everything I have tried returns a null value.
This is the code:
Code:
public final void a(boolean z) {
if (z) {
if (this.W == null) {
this.W = new TextView(getContext());
this.W.setBackgroundResource(android.support.design.widget.b.AnonymousClass7.ay);
this.W.setGravity(17);
LayoutParams marginLayoutParams = new MarginLayoutParams(-2, -2);
marginLayoutParams.bottomMargin = getContext().getResources().getDimensionPixelSize(android.support.design.widget.b.AnonymousClass5.ap);
addView(this.W, marginLayoutParams);
this.h = this.W;
}
this.W.setText(k.e(getContext(), this.a.k).toUpperCase());
this.W.setTextSize(a(getResources()));
this.W.setVisibility(0);
this.t = true;
return;
}
if (this.W != null) {
this.W.setVisibility(8);
}
this.t = false;
}
This is one of the ways in which I have tried to obtain value.
Code:
findAndHookMethod(class, "a", boolean.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(XC_MethodHook.MethodHookParam params) throws Throwable {
super.afterHookedMethod(params);
TextView textView = (TextView) params.thisObject;
if (textView!=null) {
textView.setTextColor(color);
}
}
});
I have also tried the following:
Code:
TextView textView = (TextView) XposedHelpers.getObjectField(p.thisObject, "W");
and
Code:
TextView textView = (TextView] params.args[0];
But nothing is working.
Is it possible to get the TextView? and if it's possible, how to do it?
Problem solved, I had to assign the private variable field as setAccessible(true).
