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?
Code:
[DllImport("ril.dll")]
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();
}
private static AutoResetEvent waithandle = new AutoResetEvent(false);
public delegate void RILNOTIFYCALLBACK(uint dwCode,
IntPtr lpData,
uint cbData,
uint dwParam);
public delegate void RILRESULTCALLBACK(uint dwCode,
IntPtr hrCmdID,
IntPtr lpData,
uint cbData,
uint dwParam);

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

Webclient Help

how do i replicate this under windows mobile. The first function works flawlessly however the second version (Which is required to run on windows mobile 6.1-6.5) doesn't.. If anyone has any idea how to fix it i'm willing to try it out.
Thanks
Code:
private static byte[] WebPost(string url, byte[] data)
{
var webClient = new WebClient();
return webClient.UploadData(url, data);
}
This dont.
Code:
private static byte[] WebPost(string url, byte[] data)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.Timeout = 10000; // 10 secs
request.Method = "POST";
byte[] requestPostBuffer = System.Text.Encoding.GetEncoding(1252).GetBytes(ByteArrayToStr(data));
request.ContentLength = requestPostBuffer.Length;
Stream requestPostData = request.GetRequestStream();
requestPostData.Write(requestPostBuffer, 0, requestPostBuffer.Length);
requestPostData.Close();
// initialize the httpweresponse object
HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();
// set our encoding
Encoding enc = System.Text.Encoding.GetEncoding(1252);
//initialis the webresponse stream with our encoding
StreamReader webResponseStream = new StreamReader(webResponse.GetResponseStream(),enc);
// create a string to copy it all into.
string streamedData = webResponseStream.ReadToEnd();
webResponse.Close();
webResponseStream.Close();
byte[] convertedResponse = StrToByteArray(streamedData);
convertedResponse = Encoding.Convert(System.Text.Encoding.Default, Encoding.GetEncoding(1252),convertedResponse);
return convertedResponse;

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)

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.

Unblocking thread safe queue - check code, please (and use, if right for you)

Hi friends.
I must solve big problem to finish HaRET (and other native applications) managed wrapper and UI (i. e. for example managed Silverlight UI controlled from unmanaged code), safe WP7 FTP client, interprocess cooperation on WP7, etc.
I know it is a basic issue, which is probably solved many time in operating systems (windows messages etc.) and many other examples.
But, I could find no any source code for queue, which is:
1. safe for more writers (threads from more processes) and for one reader,
2. unblocking for all writers,
3. unblocking for reader.
I found only very much unblocking ringbuffers or blocking queues, no one unblocking unlimited queue. Please, send corrections if I am bad looking.
Then, I tried code it...
First I want use std::queue with Thread Local Storage identifications (one subqueue for all writer and one abqueue for reader). But, TLS is very limited on CE based systems and I am not sure, if it solve interprocess safety too.
Finally, I tried to write the following code. It is designed for interthread queue only still, but interprocess can be added by safe named filemapping probably. Tell your opinion, it will be the basis for many complex applications here. For many years I have not worked with low-level synchronisation, I could make a fundamental mistake. So far I've missed templates and any wrapper, it's just the basic idea, usable in both C/C++ with very little changes:
PHP:
// This queue is unblocking and thread safe, when:
// 1. more writers are allowed,
// 2. one reader is allowed only.
// Motto: Pointers queue is both-directional, but frontal direction is changed by writers, backward direction by reader only!
#ifndef InterlockedExchangePointer
#define InterlockedExchangePointer(Target, Value) ((PVOID)InterlockedExchange((PLONG)(Target), (LONG)(Value)))
#endif

#define InterlockedCompareExchangePointer(Destination, ExChange, Comperand) ((PVOID)InterlockedCompareExchange((PLONG)(Destination), (LONG)(ExChange), (LONG)(Comperand)))
#endif
typedef struct SQItem
{
SQItem * pNext;
SQItem * pPrev;
void * pValue;
} * PItem;
SQItem EmptyItem = {NULL, NULL, NULL};
PItem pFront = &EmptyItem;
PItem pBack = &EmptyItem;
// Empty queue contains one item with both directions pointers nulled.
bool push_front(void * pNewValue) // nonblocking push, but theoretically forever cycle is possible for low priority thread! Practically improbable.
{
if (!pNewValue)
{
return false;
}
PItem pNewFront = new SQItem;
if (pNewFront)
{
PItem pProbablyFront;
InterlockedExchangePointer(&pProbablyFront, pFront);
pNewFront->pNext = pProbablyFront;
pNewFront->pPrev = NULL;
pNewFront->pValue = pNewValue;
while (InterlockedCompareExchangePointer(&pFront, pNewFront, pProbablyFront) != pProbablyFront)
{ // Another writer changed front pointer, active writer must try it again.
InterlockedExchangePointer(&pProbablyFront, pFront);
pNewFront->pNext = pProbablyFront;
}
return true; // Success allways.
}
return false; // Insufficient memory.
}
void * pop_back() // one reader allowed only!!!
{
PItem pBackward;
InterlockedExchangePointer(&pBackward, pFront); // Safe copy of actual front pointer
if (pBackward == pBack) // Queue is empty in time of interlocked attempt.
{
return NULL;
}
if (!pBack->pPrev)
{ // If backward queue is not continued here, reconstruct it from safe front pointer.
while (pBackward != pBack && !pBackward->pNext->pPrev)
{
pBackward->pNext->pPrev = pBackward;
pBackward = pBackward->pNext;
}
}
// One reader can safe read from back and manipulate with backward queue.
PItem pDelete = pBack;
pBack->pPrev->pNext = NULL;
pBack = pBack->pPrev;
delete pDelete;
return pBack->pValue;
/* // This is not necessary, but it is more clean:
void * pResult = pBack->pValue;
pBack->pValue = NULL;
return pResult;
*/
}
I am not sure, if heap allocation is not more "blocking" operation due to swapping and mm priorities, then object/signal waiting. What do you mean about it?
Mirror principle can be used to OneToMore queue making. Thanks unblocking, MoreToOne and OneToMore can be immeditelly piped to MoreToMore one.
But, when CE systems do not support two coupled pointers interlocked functions, there is no possibility to identify allowed reader safely, then this has not great significance.
As well, MoreToOne is much more needed now.

Xposed access variables in methods

Hello,
Iam working on a XposedModule and I need to get a variable from an other class. I have access to this class and I can access the global variables from this class but I can not access a variable which is only available in a method.
using:
Code:
Class<?> ProfileInfoClass = XposedHelpers.findClass("com.hi",lpparam.classLoader);
XposedBridge.hookAllMethods(ProfileInfoClass,"hie",new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
String s = (String)XposedHelpers.getObjectField(param.thisObject,"hello2"); //not found
}
});
with this class:
Code:
public class hi(){
String hello = "hello"; //This variable I can get
public void hie(){
String hello2 = "hi"; //This Variable I can not get using XposedHelpers.getObjectField(param.thisObject,"hello2");
}
}
Is there an other way to access variables inner Mehtods?
Thanks. Jojii

Nope, you can't.
