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

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.
I found a solution!

hello! i hope this is the right forum for my request.
i`ve tried to hack some files from JS2, which supports national roaming without data roaming enabled, into the deodexed JVK framework.jar. the result was crashing com.....phone and no working phone function.

you can see in the code of JS2 there is some code with "isNationalRoaming" which in JVK does not exist. i think this is the reason why national roaming without data roaming enabled is not working in JVK (and also many other sgs roms). i`ve tried to swap the JS2 GsmServiceStateTracker.smali file into the JVK framework, smali it back to .dex and put services.dex back into framework.jar with 7zip. the result was no working com...phone.
i`m no pro, so i think i did something wrong and some of you pro devs maybe have the answer how to do this. many users with virtual network operators like hutchison 3, bob, yesss, and many more would be happy if there will be a way without enabling the risky dataroaming, which could be very expensive when you are geting near a frontier and using data from foreign countries.
push
unwanted data roaming could be really expensive, please help. a lot of users would love you for a working solution! i would donate some beers for a working howto/fix!
to all MVNO users like 3, bob, yesss, .... push this thread with your comments how you would love national roaming without the risk of high costs in the near of frontiers!
I think solution could be easier
Who is your mobile provider?
BOB in austria, MVNO in a1 network.
bob: at 23211
a1: at 23201
Extract this file, paste 'spn-conf.xml' on system/etc/ and reboot
Let me know if it works!
IT WORKS! THANX DUDE!
here are the promised beers: 9J3661079T435484J
Glad tit worked!

Should this file also work for the Desire (Provider= 3 Austria)
Greetings
r u schnello from braunau?
i think it should work. if u have root, try it.
if it doesn`t work, delete the file again. it won`t harm anything.
edit: the fake_home data for 3 isn`t in the file. i will try to find some more infos about 3 roaming.

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)

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.
Is there a way to convert a IR pattern from a Android ~4.4.2 to 4.4.3 compatible pattern.
Here is a example how they look like

private static final int[] IR_SIGNAL_TIME_LENGTH = {4499,4499,578,1683,578,1683,578,1683,578,552,578,552,578,552,578,552,578,552,578,1683,578,1683,578,1683,578,552,578,552,578,552,578,552,578,552,578,552,578,552,578,1683,578,552,578,552,578,552,578,552,578,552,578,1683,578,1683,578,552,578,1683,578,1683,578,1683,578,1683,578,1683,578,23047};
I'm getting a close but not perfect result with this..
