Start the default WM 6.5 lockscreen in code

Does anyone have a small example how to code this?
Much appriciated

Ok, this C# code does work. But not on all emulators. In 6.5 Professional it works.
1.
I need something like this in C++
Anyone?
2.
Can I call this keyevent from a service?
Code:
SystemCalls.SendKey(SystemCalls.VK_F22);
public class SystemCalls
{
[DllImport("coredll", SetLastError = true)]
private static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
//See more at http://msdn2.microsoft.com/en-us/library/ms927178.aspx
public const byte VK_NONAME = 0xFC; // Do nothing
public const byte VK_ESC = 0x1B; // Smartphone back-button
public const byte VK_F4 = 0x73; // Home Screen
public const byte VK_APP6 = 0xC6; // Lock the keys on Smartphone
public const byte VK_F22 = 0x85; // Lock the keys on PocketPC (VK_KEYLOCK)
public const byte VK_F16 = 0x7F; // Toggle Speakerphone
public const byte VK_OFF = 0xDF; // Power button
/// <summary>
/// Puts `key` into to global keyboard buffer
/// </summary>
/// <param name="key"></param>
public static void SendKey(byte key)
{
const int KEYEVENTF_KEYUP = 0x02;
const int KEYEVENTF_KEYDOWN = 0x00;
keybd_event(key, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(key, 0, KEYEVENTF_KEYUP, 0);

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

Turn off GPRS

I'm looking for a way to turn off the data (GRPS)
Search didn't brought me anything usefull, I'm sure there is somwhere the data but can't find it.
I'm especially need it for WM 6.5 (HD2)

Search around for Modaco's NoData program. It's late and I'm too tired to search it up for you right now.

Thanks for the replay but it’s not what I meant, sorry for not be clarify.
I know the NoData app and actually i just finish writing something similar but more user friendly, hope to release it asap (Now I have problem with the icon )
What I’m looking is a way to turn off programmatically the data connection of the device, what the CommManager in the HTC sense do.
I tried to use the RAS api but it didn't work

look for jmlcomm.exe here at xda and use it in your app.simple command line call.and free to use.

Thanks for the idea, I'll try it.
But I prefer to do it directly from my app. without calling external tool.

[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.
Code:
using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;

using System.Threading;
using System.IO;

TcpListener listener;
private volatile bool stop;
private volatile bool handled;
SensePanelItem state;
SensePanelTextboxItem response;
Thread serverThread;
public ServerForm(IPEndPoint local)
{
InitializeComponent();
this.local = local;
SetupList();
}
private void SetupList()
{
SensePanelDividerItem infos = new SensePanelDividerItem("infd", "Infos");
mainList.AddItem(infos);
mainList.AddItem(new SensePanelItem("Local-Endpoint") { PrimaryText = "Local-Endpoint", SecondaryText = local.ToString() });
mainList.AddItem(state = new SensePanelItem("Status") { PrimaryText = "Status", SecondaryText = "Wird gestartet..." });
mainList.AddItem(new SensePanelDividerItem("Response", "Response"));
mainList.AddItem(response = new SensePanelTextboxItem("body") { LabelText = "HTML-Body, welcher auf Requests gesendet wird.", Text = "<span style =\"color:red;font-size:30pt\">It works!!</span>" });
mainList.AddItem(new SensePanelDividerItem("Requests", "Requests"));
}

if (listener != null)
{
StopServer(true);
}

NetworkStream stream = client.GetStream();
StreamReader reader = new StreamReader(stream);
ReadHttpRequest(reader);

{
writer.WriteLine("HTTP/1.1 200 OK");
writer.WriteLine("Date: " + DateTime.Now.ToString());
writer.WriteLine("Content-Length: "+ length.ToString());
writer.WriteLine("Connection: close");
writer.WriteLine("Content-Type: text/html; charset=utf-8");
writer.WriteLine();
}
private void ReadHttpRequest(StreamReader reader)
{
string buffer = null;
while (buffer != "")
buffer = reader.ReadLine();
}
int counter = 0;
private string GetResponse(IPEndPoint remote)
{
counter++;
mainList.AddItem(new SensePanelItem(counter.ToString()) { PrimaryText = remote.ToString(), SecondaryText = "Response:" + counter.ToString() });
return response.Text;
}
private void EndHTML(StringBuilder writer)
{
writer.AppendLine("</body>");
writer.AppendLine("</html>");
}
private void StartHTML(StringBuilder writer)
{
writer.AppendLine("<?xml version=\"1.0\"?>");
writer.AppendLine("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">");
writer.AppendLine("<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"de\" lang=\"de\">");
writer.AppendLine("<head>");
writer.AppendLine("<title>SmartWebServer</title>");
writer.AppendLine("<meta name=\"author\" content=\"Alexander Kayed\">");
writer.AppendLine("</head>");
writer.AppendLine("<body>");
}
private void StopServer(bool restart)
{
stop = true;
serverThread.Join();
if (restart)
StartServer();
}
private void ServerForm_Load(object sender, EventArgs e)
{
StartServer();
}
private void ServerForm_Closed(object sender, EventArgs e)
{
StopServer(false);
}
private void menuItem1_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
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?

Get TextView from method [RESOLVED]

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).
