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;

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.

Turn off phone

I need to turn off the phone (radio?) in my application
The only thing I found is by using lineSetEquipmentState but I couldn't find how to work with it.
Another option is with the openNetCf.tapi but this dll isn't free.
Any ides?

Someone? something?
Other option will be if possible to call flight mode

You can do this via RIL:
Code:
RIL_SetEquipmentState(FHandle,RIL_EQSTATE_MINIMUM);
Here FHandle is handle to opened RIL.

Thanks for the info, seems the right way.
However something doesn't work, every thing looks ok, the hRes is 0 but nothing happens.
Any ideas?

private static extern IntPtr RIL_SetEquipmentState(IntPtr hRil);
public static bool SetAirplaneState()
{
IntPtr hRil = IntPtr.Zero;
IntPtr hRes = IntPtr.Zero;
hRes = RIL_Initialize(1, // RIL port 1
new RILRESULTCALLBACK(SetEquipmentStateCallback), // function to call with result
null, // function to call with notify
0, // classes of notification to enable
0x00000001, // RIL parameters
out hRil); // RIL handle returned
if (hRes != IntPtr.Zero)
{
return false;
}
hRes = RIL_GetCellTowerInfo(hRil);
waithandle.WaitOne();
RIL_Deinitialize(hRil);
return true;
}
private static void SetEquipmentStateCallback(uint dwCode, IntPtr hrCmdID, IntPtr lpData, uint cbData, uint dwParam)
{
waithandle.Set();
}

What do you want to achieve? If you want to turn off the phone, you should use RIL_SetEquipmentState. But in your code you obtain Cell Tower info via RIL_GetCellTowerInfo.
Also, if I remember rightly, you must specify RILNOTIFYCALLBACK in RIL_Initialize.

Correct, sorry I made mish-mash in the code I copied here.
My error was that I forgot to pass the second parameter to the SetEquipmentState function.
Works great now, Thanks!

Any chance of publishing this code?
Am I right in that it takes some time for the application to quit?
Thanks,

ajhvdb, this code works quite fine. And yes, it may take a while to quit app.

If I past your code into my code I'm missing RIL_Initialize, RIL_GetCellTowerInfo.
Sorry for being slow with this but I never used delegates and RIL before

Boolean Replacement

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:
XposedHelpers.findAndHockMethod("com.example.utils.RootCheck", lpparam.classLoader, "isRooted", boolean.class, new XC_MethodHook() {
@Override

}
});
Xposed say me nosuchmethoderror com.example.utils.RootCheck#isRooted(boolean)..
Can help me..

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 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
