C#: Make program run even though it's minimized

I'm programming an application (WM 6.1) that should do things regardless if the program is active or minimized (user pressed the X button). This is where my problem occurs, my program is set on "pause" when the program is minimized. I need it to run even though it's in the background. How to solve this?

Hi Pytagoras,
I haven´t made a lot of C# programs, but I think that only the main thread is pause when the program is minimized, but the additional threads don´t. So if you need something running on background you need to implement it on an additional thread...
See you

Thanks for your reply
I'm new to threads, haven't really needed them before. So I found some examples:
Code:
class ThreadTest {
private void frmProgram_Load(object sender, EventArgs e)
{
Thread t = new Thread (WriteY);
t.Start(); // Run WriteY on the new thread
}
static void WriteY() {
while (true) Console.Write ("y"); // Write 'y' forever
}
}
Of course I loaded my own method instead of the WriteY example method described here. The thread get started in the Load event of the main form, so it should execute. However, it doesn't work when the program is minimized, and with this thread way of doing it, it doesn't work when it's opened either. (the program should notice a sms ticking in, and do something based on it).
Any help would be greatly appreciated (there should be a dedicated forum on xda for this kind of things / different programming languages..just a comment)

Try something like this... should work...
Code:
class ThreadTest {
private Thread t;
private void frmProgram_Load(object sender, EventArgs e)
{
t = new Thread(new ThreadStart(WriteY));
t.IsBackGround = true;
t.Start();
}
static void WriteY() {
while (true) Console.Write ("y"); // Write 'y' forever
}
}

Strange, it still don't work. I even tried with the code you posted without changing any of it, and still it don't run. It won't even write to the console

The issue is that the console.write is not showing on "Output Window"... see the code below... that it keeping update the file even if minimized...
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using System.IO;
namespace ThreadTest
{
public partial class Form1 : Form
{
private Thread t;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
t = new Thread(new ThreadStart(WriteY));
t.IsBackground = true;
t.Start();
}
private void WriteY()
{
while (true)
{
FileStream fs = new FileStream("\\test.txt", FileMode.Create);
StreamWriter w = new StreamWriter(fs, Encoding.UTF8);
w.WriteLine(DateTime.Now.ToString());
w.Flush();
w.Close();
fs.Close();
}
}
}
}

Thank you for your help, but I get this when I run your code:
System.IO.IOException:
"The process can not access the file '\\test.txt' because it is being used by another process."

The possibility for that is that you are running the example more than once...

I don't know what's happening, but I don't like the fact that messageInterceptor is local to startMessageDetection(). The thread will not continue forever, since it is not looping... the three operations in startMessageDetection() will be performed and the thread will cease. I would make messageInterceptor a member of the form, assign it in startMessageDetection(), and try it without the thread. Does this work?

try making it a process instead of an application. Processes are ment to be running in the background.

[APP] Shark for Root + SharkReader

There were AndroShark, tool for capturing traffic on Android. But there were no newer releases and it seems that original developer dropped project. I liked this tool and used it a lot. But it was set to expire... So there was no simple capture tools available... http://forum.xda-developers.com/showthread.php?t=675206 is home of AndroShark.
So I made Shark for Root, alternative for AndroShark. Some people asked for possibility to see packets on phone, and for that purpose SharkReader has created (first, "quick and dirty" release).
Shark for Root
With tcpdump http://swapper.n3o.lv/lv.n3o.shark_1.0.2.apk
Native http://swapper.n3o.lv/lv.n3o.sharknative_1.0.2.apk
SharkReader - unstable...
(note - run Shark Updater to get traffic analysator)
http://swapper.n3o.lv/lv.n3o.sharkreader_0.1.6.apk
Older versions http://swapper.n3o.lv/

EPIC
Thank you!

If you press stop, it doesn't truly stop. tcpdump seems like it is still going in the background. The file will continue getting larger and larger even though it has been told to stop capturing.

Thank you.
Far as I can tell it's working good, Thanks for the reader, helps a lot, I can see this program becoming a portable wireshark app for android, keep up the great work and thank you.

Default parameters are -vv -s 0
Can You send me more information about Your error?

Could someone tell about using different parameters or point me to some website where i could study these?(now i got the defaults)
And when i open Shark reader i see many "RAW Packet" but i cant get any information from them, just "Packet #number".
.pcap files are fine when i open them with Wireshark.
At the bottom i see this: -NULL , what else i can use here and how it effects?
Interesting app, keep up the good work!

A changelog would be nice.

I also can not run Shark on my X10. I get the error 'reloc_library [1215]: cannot locate _aeabi_fdiv CANNOT LINK EXECUTABLE

Hello!
For Shark for Root parameters look at some examples/manuals about tcpdump. F.e. http://www.cs.ucr.edu/~marios/ethereal-tcpdump.pdf
Shark reader marks packets as RAW if it does not recognize it (currently it means it's not tcp/udp packet).
For filters you can use any tag and any tag with - sign. Tags are those in first column. Traffic is tagged by content (signature) and port. Signatures and ports you may update with Shark Updater (included in Shark Reader), but I have too little time to manage all those resources. I'll make this system public for tags submission/port submission, so interested users will be able to add necessary tags.
So, if you want to see only non zero bytes packets with http content, you may use this setting:
Code:
[ ] all [o] none | http -NULL |
Filters are processed in order. So http shows all http packets and -NULL hides those with nulls. First option works as global filter (show all or show none).
Warning! Not all traffic is tagged, so if you miss something, it could mean some tags are incorrectly assigned or skipped.
Hope it helps.

ex87,
Awesome work bro, life got too busy for me to work more on AndroShark, I really didn't drop it on purpose. But with a busy life, and me still really new at java, it was just too much. I am really glad you picked up the idea and ran with it.
Do you have any plans to opensource it at all (no worries if you dont)? I would like to be a contributor if you do decide to open source it.
I really doubt this is of any use. It was the second java app I ever worked on, and was really just a front end. Below is androshark source code. Like I said, this was my second attempt at writing an app, so please don't laugh If I were to do it today, I would completely change how it worked. /res/raw/sharktap was just tcpdump.

Apparently you know, and still haven't helped those of us who have no idea what this app is for!

When is CM7 coming out?

Well, now that I have your attention, my REAL question is this: Is there a way to make apps like the Amazon marketplace think they're on wifi so I don't get that stupid "you can't download this because it's too big for a cellular network"?
***** please, I pay for unlimited data and I plan to use it.

HAHAHA I like your tactics for getting attention.
A while back I made a remark that the only way to get peoples attention in these forums is to ask if CM7 is coming out in the title and then ask the real question in the body.
Well played
Also no, there's no way to trick Amazon

I've actually been working on figuring out a way to do this.
Any app that tries to figure out how it's connected queries the same class in the system called NetworkInfo.class.
There are two methods within NetworkInfo.class that report the network type: getType() and getTypeName(). getType() returns a machine-readable answer, while getTypeName() is human-readable.
Code:
public int getType() {
return mNetworkType;
}
Code:
public String getTypeName() {
switch (mNetworkType) {
case ConnectivityManager.TYPE_WIFI:
return "WIFI";
case ConnectivityManager.TYPE_MOBILE:
return "MOBILE";
default:
return "<invalid>";
}
}
I haven't had the resources (primarily time) to dig that far into things, but if we could figure out a way to inject something between Amazon and the getType() or getTypeName() calls, we could report to it that we're on WiFi regardless of how we're actually connected.

Wow, Computer Science II is actually helping me be able to read this. So, what type of object is mNetworkType and where is it defined? We could get it to just return that its on wifi all the time. Also, do you know what Amazon calls? GetType or GetTypeName?

Interesting stuff. There's an iPhone app for jailbroken phones that performs this function on an app-by-app basis. With this code identified, something similar might be possible on Android. I haven't done any Android dev yet, so I don't know how much help I might be. Is there a way to easily (and cheaply) intercept method calls on Android? If so, there might be a way to intercept the getType and getTypeName calls and then modify them on a case-by-case basis so that the call can be diverted to a different function. I'm talking completely theoretical here...I don't know what is offered by the Android SDK.

That was exactly where my investigation has hit the wall at the moment (and then I got busy finishing my basement).
There are a couple of ways to do it, really. Someone could modify the appstore apk to wrap any calls to getType() and getTypeName(), but that would only be on that particular apk. IIRC, the market does it for large apk downloads as well.
Other apps also look at what your network type is.
I'd love to have something that allows me to toggle what the applications see, regardless of the actual state (I'm thinking of things like Verizon's Skype, etc).
The problem with all of this is that NetworkInfo.class is deep in the core OS, so intercepting any calls to it's methods might be rather difficult at best.

I'm guessing that making isNetworkWifi() return true would allow for downloads of large files over the cell network. I might repack the APK and post it here if I find the time.

All right, I decompiled the dex file into smali class files, made the change, recompiled, and produced an APK that does not have the wifi restriction, but I'm having problems with signing. I ran a signing tool on the APK, but even after that my phone still fails to install the app (I do have the previous version of the app uninstalled). Has anyone else had experience with this?

Yeah, sure. (For anyone else attempting to download this, it will not install in its current form).

Anyone have any luck with the signing?

I'm having troubles too. Is there any way to bypass the sign check? I assume its similar to a CRC or MD5 check.
EDIT: http://developer.android.com/guide/publishing/app-signing.html
What if you saved & signed as a different app name?

Just had an idea. What if we packed it into a ROM as a system APK?

Great job reading the thread and making a relevant comment.
Aside from that: CM8 would be Honeycomb-based if it were to ever be made, which is unlikely, since it's the one version of Android that's closed-source. ICS will give rise to CM9

Why, thank you.
I was bored and just posted that. I knew this thread was about the Amazon appstore(had read some posts from the first page a few days ago).

[Q] WP7 facebook application, posting blank status updates only

Hi ive written a simple application for windows phone 7 that posts a status update to the users wall. This is all working correctly except for the fact that when the status update is done it is always empty. I am trying to make it so that the user can enter what they would like to say in a text box, but obviously so far this isnt working and all that is being sent is an empty status update. I am connecting to the facebook api and the authentication all works correctly or the post would not be sent at all. Ive searched all over the web and havent found anyone with the same issue as of yet.
Here is the status update code that I am working on:
Code:
private void PostStatusUpdate(string status, Action<bool, Exception> callback)
{
var request = HttpWebRequest.Create("https://graph.facebook.com/me/feed");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.BeginGetRequestStream((reqResult) =>
{
using (var strm = request.EndGetRequestStream(reqResult))
using (var writer = new StreamWriter(strm))
{
writer.Write("access_token=" + _accessToken);
writer.Write("&message=" + HttpUtility.UrlEncode(status));
}
request.BeginGetResponse((result) =>
{
try
{
var response = request.EndGetResponse(result);
using (var rstrm = response.GetResponseStream())
{
var serializer = new DataContractJsonSerializer(typeof(FacebookPostResponse));
var postResponse = serializer.ReadObject(rstrm) as FacebookPostResponse;
callback(true, null);
}
}
catch (Exception ex)
{
callback(false, ex);
}
}, null);
}, null);
}
[DataContract]
public class FacebookPostResponse
{
[DataMember(Name = "id")]
public string Id
{
get;
set;
}
}
private void PostUpdate_Click(object sender, RoutedEventArgs e)
{
PostStatusUpdate(this.StatusText.Text, (success, ex) =>
{
this.Dispatcher.BeginInvoke(() =>
{
if (success && ex == null)
{
MessageBox.Show("Status updated");
NavigationService.Navigate(new Uri("/Views/MainPage.xaml", UriKind.Relative));
}
else
{
MessageBox.Show("Unable to update status");
}
});
});
}
Has anyone encountered this before / know any solution to this problem?
Any insights into this would be much appreciated

You are using the asyncronous method with no callback function
Looks like you should be using a callback function - See examples here
http://msdn.microsoft.com/en-us/lib...est.begingetrequeststream(v=vs.90).aspx#Y1760
http://msdn.microsoft.com/en-us/lib...brequest.begingetrequeststream(v=vs.100).aspx
Also, did the same code work at one point?
It could be as simple as not closing your connections. I ran into this in the Weather City Editor that I wrote for Windows Mobile.
When I added code to hit accuweathers site to look up the code, I had forgotten to close the connection. I would need to wait until the connection timed out before it would work again.
I think yours is differnt though, since it is updating blank.
But, you could just use GetRequestStream, which does not need the callback function, synce it is not asyncronous. See example code: http://msdn.microsoft.com/en-us/library/d4cek6cc.aspx

Thanks for the reply
Thanks for the reply, the code has never worked so far it has only posted blank facebook statuses, I will see if adding an asynchronous call back makes a difference.
Thanks

How to Read PDF file Without save on Local storage windows phone 8 C#

I need to open pdf file without store on local storage. i tried this code but i am facing some issues when i am try to read pdf file through PDF Reader, Adobe Reader, etc. after click back navigation i deleted current file from local folder. But after closed my application and I am directly open PDF Reader, Adobe Reader... etc. File is exist(still have on my library). I could not delete the file. Please let me know is possible on windows phone 8 C#.
please see my code below.
Code:
protected async override void OnNavigatedTo(NavigationEventArgs e)
{
try
{
using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
{
using (var fileStream = store.OpenFile("your-file.pdf", FileMode.Truncate, FileAccess.ReadWrite, FileShare.ReadWrite))
{
fileStream.Flush();
fileStream.Close();
if (store.FileExists("your-file.pdf"))
{
store.DeleteFile("your-file.pdf");
}
StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;
await local.DeleteAsync(StorageDeleteOption.PermanentDelete);
}
}
}
catch
{
//File does not exist.
}
}
private async void Button_Click(object sender, RoutedEventArgs e)
{
//RestSharp from Nuget
var client = new RestClient("https://dvtp17lb47b1q.cloudfront.net");
var request = new RestRequest("/magazine/file/PDF-2.pdf?c34tP5IxEK=2b26c756615a40844a6564d13a3eb875", Method.GET);
var response = await client.ExecuteTaskAsync(request);
byte[] buffer = response.RawBytes;
using (IsolatedStorageFile storageFile = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = storageFile.OpenFile("your-file.pdf", FileMode.Create))
{
await stream.WriteAsync(buffer, 0, buffer.Length);
}
}
StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;
StorageFile pdffile = await local.GetFileAsync("your-file.pdf");
// Launch the pdf file.
Windows.System.Launcher.LaunchFileAsync(pdffile);
}
Main Functionality is only read the pdf file without saving.
