• Email Tracking - GMail

  - by Abs

  Hello all, I am creating my own email tracking system for email marketing tracking. I have been able to determine each persons email client they are using by using the http referrer but for some reason GMAIL does not send a HTTP_REFERRER at all! So I am trying to find another way of identifying when gmail requests a transparent image from my server. I get the following headers print_r($_SERVER);: DOCUMENT_ROOT = /usr/local/apache/htdocs GATEWAY_INTERFACE = CGI/1.1 HTTP_ACCEPT = */* HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP_ACCEPT_ENCODING = gzip,deflate,sdch HTTP_ACCEPT_LANGUAGE = en-GB,en-US;q=0.8,en;q=0.6 HTTP_CONNECTION = keep-alive HTTP_COOKIE = __utmz=156230011.1290976484.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utma=156230011.422791272.1290976484.1293034866.1293050468.7 HTTP_HOST = xx.xxx.xx.xxx HTTP_USER_AGENT = Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.237 Safari/534.10 PATH = /bin:/usr/bin QUERY_STRING = i=MTA= REDIRECT_STATUS = 200 REMOTE_ADDR = xx.xxx.xx.xxx REMOTE_PORT = 61296 REQUEST_METHOD = GET Is there anything of use in that list? Or is there something else I can do to actually get the http referrer, if not how are other ESPs managing to find whether gmail was used to view an email? Btw, I appreciate it if we can hold back on whether this is ethical or not as many ESPs do this already, I just don't want to pay for their service and I want to do it internally. Thanks all for any implementation advice. Update Just thought I would update this question and make it clearer in light of the bounty. I would like to find out when a user opens my email when sent to a GMail inbox. Assume, I have the usual transparent image tracking and the user does not block images. I would like to do this with the single request and the header details I get when the transparent image is requested.

• JME: How to get the complete screen in WHITE without buttons, etc etc

  - by Sepala

  Please have a look at the following code /* * To change this template, choose Tools | Templates * and open the template in the editor. */ import javax.microedition.midlet.*; import javax.microedition.lcdui.*; /** */ public class Midlet extends MIDlet{ private Form f; private Display d; private Command start,stop; private Thread t; public Midlet() { t = new Thread(new TurnLightOn()); } public void startApp() { f = new Form("Back Light On"); d = Display.getDisplay(this); d.setCurrent(f); start = new Command("Turn On",Command.OK,0); stop = new Command("Turn Off",Command.OK,1); f.addCommand(start); f.setCommandListener(new Action()); } public void pauseApp() { } public void destroyApp(boolean unconditional) { this.notifyDestroyed(); } private class Action implements CommandListener { public void commandAction(Command c, Displayable dis) { f.append("Light is Turnning On"); t.start(); } } private class ActionOff implements CommandListener { public void commandAction(Command c, Displayable dis) { } } private class TurnLightOn implements Runnable { public void run() { f.append("Working"); for(int i=0;i<100;i++) { try { d.flashBacklight(200); d.vibrate(200); Thread.sleep(1000); } catch (InterruptedException ex) { ex.printStackTrace(); } } } } } First, Please note I am a 100% newbie to Java Mobile. In here, I am making the light on and vibrate on when user click the button. However, I really wanted to create a SOS application which turn the whole screen into white, and go to black, like that, in the thread. I guess I didn't achieve that by this app because even the lights are on, the buttons are still there. I tried to turn the "Form" color to "white" but it seems like JME has no "Color" class! Please help!

• .NET Sockets Buffer Overflow No Error

  - by Michael Covelli

  I have one thread that is receiving data over a socket like this: while (sock.Connected) { // Receive Data (Block if no data) recvn = sock.Receive(recvb, 0, rlen, SocketFlags.None, out serr); if (recvn <= 0 || sock == null || !sock.Connected) { OnError("Error In Receive, recvn <= 0 || sock == null || !sock.Connected"); return; } else if (serr != SocketError.Success) { OnError("Error In Receive, serr = " + serr); return; } // Copy Data Into Tokenizer tknz.Read(recvb, recvn); // Parse Data while (tknz.MoveToNext()) { try { ParseMessageAndRaiseEvents(tknz.Buffer(), tknz.Length); } catch (System.Exception ex) { string BadMessage = ByteArrayToStringClean(tknz.Buffer(), tknz.Length); string msg = string.Format("Exception in MDWrapper Parsing Message, Ex = {0}, Msg = {1}", ex.Message, BadMessage); OnError(msg); } } } And I kept seeing occasional errors in my parsing function indicating that the message wasn't valid. At first, I thought that my tokenizer class was broken. But after logging all the incoming bytes to the tokenizer, it turns out that the raw bytes in recvb weren't a valid message. I didn't think that corrupted data like this was possible with a tcp data stream. I figured it had to be some type of buffer overflow so I set sock.ReceiveBufferSize = 1024 * 1024 * 8; and the parsing error never, ever occurs in testing (it happens often enough to replicate if I don't change the ReceiveBufferSize). But my question is: why wasn't I seeing an exception or an error state or something if the socket's internal buffer was overflowing before I changed this buffer size?

• Why is it assumed that send may return with less than requested data transmitted on a blocking socke

  - by Ernelli

  The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

• Removing a view from it's superview causes memory error - why?

  - by mystify

  Xcode is throwing an error at me: malloc: * error for object 0x103f000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I tracked down the code until a line where I do this: - (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context { // retainCount of myView is 2! (one for the retain-property, one for beeing a subview) [self.myView removeFromSuperview]; // ERROR-LINE !! self.myView = nil; } When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view! It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory. Did anyone else encounter such issues? iPhone SDK 3.0.

• Deadlock in ThreadPoolExecutor

• Why do Firefox and Opera ignore max-width inside of display: table-cell?

  - by brad

  The following code displays correctly in Chrome or IE (the image is 200px wide). In Firefox and Opera the max-width style is ignored completely. Why does this happen and is there a good work around? Also, which way is most standards compliant? Note One possible work around for this particular situation is to set max-width to 200px. However, this is a rather contrived example. I'm looking for a strategy for a variable width container. <!doctype html> <html> <head> <style> div { display: table-cell; padding: 15px; width: 200px; } div img { max-width: 100%; } </style> </head> <body> <div> <img src="http://farm4.static.flickr.com/3352/4644534211_b9c887b979.jpg" /> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec facilisis ante, facilisis posuere ligula feugiat ut. Fusce hendrerit vehicula congue. at ligula dolor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. leo metus, aliquam eget convallis eget, molestie at massa. </p> </div> </body> </html> [Update] As stated by mVChr below, the w3.org spec states that max-width does not apply to inline elements. I've tried using div img { max-width: 100%; display: block; }, but it does not seem to correct the issue.

• How can a program be detected as running?

  - by ryeguy

  I have written a program that is sort of an unofficial, standalone plugin for an application. It allows customers to get a service that is a lower priced alternative then the vendor-owned one. My program is not illegal, against any kind of TOS, and is certainly not a virus, adware, or anything like that. That being said, the vendor of course is not happy about me taking his competition, and is trying to block my application from running. He has already tried some tactics to stop people from running my app alongside his. He makes it so if it is detected, his app throws a fake error. First, he checked to see if my program was running by looking for an open window with the right title. I countered this by randomizing the program title at startup. Next, he looked for the running process name. I countered this by making the app copy itself when it is started as [random string].exe and then running that. Anyways, my question is this: what else can he do to detect if my program running? I know that you can read window text (ie status bar, labels). I'm prepared to counter this by replacing the labels with images (ugh, any other way?). But what else is there? Can you detect what .dlls a program has loaded? If so, could this be solved by randomizing the dll names before loading them? I know that it's possible to get a program's signature in memory and track it that way (like a virus scanner), but the chances of him doing that probably aren't good because that sounds pretty advanced. Even though this is kinda crappy of him to be doing, its kind of fun. It's like a nerdy fist fight. EDIT: When I said it's a plugin, that is just the (incorrect) term I used. It's a standalone EXE. The "API" between my program and the other is mine is simply entering data into the controls (like textboxes, etc).

• How does the last integer promotion rule ever get applied in C?

  - by SiegeX

  6.3.1.8p1: Otherwise, the integer promotions are performed on both operands. Then the following rules are applied to the promoted operands: If both operands have the same type, then no further conversion is needed. Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank is converted to the type of the operand with greater rank. Otherwise, if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type. Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, then the operand with unsigned integer type is converted to the type of the operand with signed integer type. Otherwise, both operands are converted to the unsigned integer type corresponding to the type of the operand with signed integer type. For the bolded rule to be applied it would seem to imply you need to have have an unsigned interger type who's rank is less than the signed integer type and the signed integer type cannot hold all the values of the unsigned integer type. Is there a real world example of such a case or is this statement serving as a catch-all to cover all possible permutations?

• Using CallExternalMethodActivity/HandleExternalEventActivity in StateMachine

  - by AngrySpade

  I'm attempting to make a StateMachine execute some database action between states. So I have a "starting" state that uses CallExternalMethodActivity to call a "BeginExecuteNonQuery" function on an class decorated with ExternalDataExchangeAttribute. After that it uses a SetStateActivity to change to an "ending" state. The "ending" state uses a HandleExternalEventActivity to listen to a "EndExecuteNonQuery" event. I can step through the local service, into the "BeginExecuteNonQuery" function. The problem is that the "EndExecuteNonQuery" is null. public class FailoverWorkflowController : IFailoverWorkflowController { private readonly WorkflowRuntime workflowRuntime; private readonly FailoverWorkflowControlService failoverWorkflowControlService; private readonly DatabaseControlService databaseControlService; public FailoverWorkflowController() { workflowRuntime = new WorkflowRuntime(); workflowRuntime.WorkflowCompleted += workflowRuntime_WorkflowCompleted; workflowRuntime.WorkflowTerminated += workflowRuntime_WorkflowTerminated; ExternalDataExchangeService dataExchangeService = new ExternalDataExchangeService(); workflowRuntime.AddService(dataExchangeService); databaseControlService = new DatabaseControlService(); workflowRuntime.AddService(databaseControlService); workflowRuntime.StartRuntime(); } ... } ... public void BeginExecuteNonQuery(string command) { Guid workflowInstanceID = WorkflowEnvironment.WorkflowInstanceId; ThreadPool.QueueUserWorkItem(delegate(object state) { try { int result = ExecuteNonQuery((string)state); EndExecuteNonQuery(null, new ExecuteNonQueryResultEventArgs(workflowInstanceID, result)); } catch (Exception exception) { EndExecuteNonQuery(null, new ExecuteNonQueryResultEventArgs(workflowInstanceID, exception)); } }, command); } What am I doing wrong with my implementation? -Stan

• How can I use System.Web.Caching.Cache in a Console application?

  - by Ron Klein

  Context: .Net 3.5, C# I'd like to have caching mechanism in my Console application. Instead of re-inventing the wheel, I'd like to use System.Web.Caching.Cache (and that's a final decision, I can't use other caching framework, don't ask why). However, it looks like System.Web.Caching.Cache is supposed to run only in a valid HTTP context. My very simple snippet looks like this: using System; using System.Web.Caching; using System.Web; Cache c = new Cache(); try { c.Insert("a", 123); } catch (Exception ex) { Console.WriteLine("cannot insert to cache, exception:"); Console.WriteLine(ex); } and the result is: cannot insert to cache, exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Caching.Cache.Insert(String key, Object value) at MyClass.RunSnippet() So obviously, I'm doing something wrong here. Any ideas? Update: +1 to most answers, getting the cache via static methods is the correct usage, namely HttpRuntime.Cache and HttpContext.Current.Cache. Thank you all!

• Background worker not working right

  - by vbNewbie

  I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

• call lynx from jsp script

  - by Piero

  Hi, I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class. It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2 So I guess my execute command is ok, since it is working with that. Now when I try to call lynx, the text-based web browser, it does not work. If I call it in a terminal, it works fine: /usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2' But when I call this from my execute command, nothing happens... Any idea why? This is my execute method: public String execute(String cmd){ Runtime r = Runtime.getRuntime(); Process p = null; String res = ""; try { p = r.exec(cmd); InputStreamReader isr = new InputStreamReader(p.getInputStream()); BufferedReader br = new BufferedReader(isr); String line = null; //out.println(res); while ((line = br.readLine()) != null) { res += line; } p.waitFor(); } catch (Exception e) { res += e; } System.out.println(p.exitValue()); return res; }

• UIView animation only animating some of the things I ask it to

  - by Ben

  I have a series of (say) boxes on the screen in a row, all subviews of my main view. Each is a UIView. I want to shift them all left and have a new view also enter the screen from the right in lockstep. Here's what I'm doing: // First add a dummy view offscreen UIView * stagingView = /* make this view, which sets up its width/height */ CGRect frame = [stagingView frame]; frame.origin.x = /* just off the right side of the screen */; [stagingView setFrame:frame]; [self stagingView]; And then I set up animations in one block for all of my subviews (which includes the one I just added): [UIView beginAnimations:@"shiftLeft" context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(_animationDidStop:context:)]; [UIView setAnimationDuration:0.3]; for (UIView * view in [self subviews]) { CGRect frame = [view frame]; frame.origin.x -= (frame.size.width + viewPadding); [view setFrame:frame]; } [UIView commitAnimations]; Here's what I expect: The (three) views already on screen get shifted left and the newly staged view marches in from the right at the same time. Here's what happens: The newly staged view animates in exactly as expected, and the views already on the screen do not appear to move at all! (Or possibly they jump without animation to their end locations). And! If I comment out the whole business of creating the new subview offscreen... the ones onscreen do animate correctly! Huh? (Thanks!)

• How to instantiate spring bean without being referenced from aop:aspect

  Using Spring and Java; I have a pointcut which works OK. Now I want to remove the pointcut and AOP from the spring and just trigger the event with an event from inside the java code but I want "myAdvice" bean still called via Spring and its properties set. I want to get ridoff all advice things even in java code, no more advice or any trace of AOP, I already have a nice event system working. I just want to instantiate my bean via Spring. When I remove the second code block (one starting with "aop:config") then I noticed the bean "myAdvice" is not called and instantiated anymore. How can i stil call it set its properties without referencing it from the "aop:aspect" ? in my application context ; <bean id="myAdvice" class="com.myclass"> <property name="name1" ref="ref1" /> <property name="name2" ref="ref2" /> </bean> <aop:config proxy-target-class="true"> <aop:aspect id="myAspect" ref="myAdvice"> <aop:pointcut id="myPointcut" expression="execution(* com.myexcmethod" /> <aop:around pointcut-ref="myPointcut" method="invoke" /> </aop:aspect> </aop:config>

• Solution for cleaning an image cache directory on the SD card

  - by synic

  I've got an app that is heavily based on remote images. They are usually displayed alongside some data in a ListView. A lot of these images are new, and a lot of the old ones will never be seen again. I'm currently storing all of these images on the SD card in a custom cache directory (ala evancharlton's magnatune app). I noticed that after about 10 days, the directory totals ~30MB. This is quite a bit more than I expected, and it leads me to believe that I need to come up with a good solution for cleaning out old files... and I just can't think of a great one. Maybe you can help. These are the ideas that I've had: Delete old files. When the app starts, start a background thread, and delete all files older than X days. This seems to pose a problem, though, in that, if the user actively uses the app, this could make the device sluggish if there are hundreds of files to delete. After creating the files on the SD card, call new File("/path/to/file").deleteOnExit(); This will cause all files to be deleted when the VM exits (I don't even know if this method works on Android). This is acceptable, because, even though the files need to be cached for the session, they don't need to be cached for the next session. It seems like this will also slow the device down if there are a lot of files to be deleted when the VM exits. Delete old files, up to a max number of files. Same as #1, but only delete N number of files at a time. I don't really like this idea, and if the user was very active, it may never be able to catch up and keep the cache directory clean. That's about all I've got. Any suggestions would be appreciated.

• show() progressdialog in asynctask inside fragment

  - by just_user

  I'm trying to display a progressDialog while getting an image from a url to a imageview. When trying to show the progressDialog the parent activity has leaked window... Strange thing is that I have two fragments in the this activity, in the first fragment this exact same way of calling the progressdialog works but when the fragment is replaced and i try to make it again it crashes. This is the asynctask I'm using inside the second fragment with the crash: class SkinPreviewImage extends AsyncTask<Void, Void, Void> { private ProgressDialog progressDialog; @Override protected void onPreExecute() { progressDialog = new ProgressDialog(getActivity()); progressDialog.setMessage("Loading preview..."); if(progressDialog != null) progressDialog.show(); progressDialog.setOnCancelListener(new OnCancelListener() { public void onCancel(DialogInterface arg0) { SkinPreviewImage.this.cancel(true); } }); } @Override protected Void doInBackground(Void... params) { try { URL newurl = new URL(url); Bitmap mIcon_val = BitmapFactory.decodeStream(newurl.openConnection().getInputStream()); skinPreview.setImageBitmap(mIcon_val); } catch (IOException e) { Log.e("SkinStoreDetail", e.getMessage()); } return null; } @Override protected void onPostExecute(Void v) { if(progressDialog != null) progressDialog.dismiss(); } } I've seen a few similar questions but the one closest to solve my problem used a groupactivity for the parent which I'm not using. Any suggestions?

• How to open AsyncTask from a Thread

  - by Abhishek

  In my application I have created a SplashScreen that will b shown for 5 Seconds and after that it executes an if else case depending upon the values stored in the Preference file. If Preference file contains values then the AsyncTask code will run else the Login form will load. When i try to run my application. The thread is going to the Login form with the help of intent but when it comes to AsyncTask my application shows a force close error message. This is my SplashScreen code: public class SplashScreen extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread timer = new Thread() { public void run() { try { sleep(5000); } catch(InterruptedException e) { e.printStackTrace(); } finally { if(GoGolfPref.getEmail(SplashScreen.this)!=null && GoGolfPref.getPass(SplashScreen.this)!=null) { new LoadingScreen(SplashScreen.this, SplashScreen.this).execute("login_page", Login.url+GoGolfPref.getEmail(SplashScreen.this)+"/"+GoGolfPref.getPass(SplashScreen.this)); } else { Intent in = new Intent(SplashScreen.this, Login.class); startActivity(in); finish(); } } } }; timer.start(); } } This is the error I am getting: 08-29 07:25:58.040: E/AndroidRuntime(2365): FATAL EXCEPTION: Thread-10 08-29 07:25:58.040: E/AndroidRuntime(2365): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.os.Handler.<init>(Handler.java:121) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.Dialog.<init>(Dialog.java:101) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.AlertDialog.<init>(AlertDialog.java:63) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:80) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:76) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.LoadingScreen.<init>(LoadingScreen.java:130) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.SplashScreen$1.run(SplashScreen.java:32) How to get this working?
