• Symbian: clear buffer of RSocket object

  - by Heinz

  Hi, I have to come back once again to sockets in Symbian. Code to set up a connection to a remote server looks as follows: TInetAddr serverAddr; TUint iPort=111; TRequestStatus iStatus; TSockXfrLength len; TInt res = iSocketSrv.Connect(); res = iSocket.Open(iSocketSrv,KAfInet,KSockStream, KProtocolInetTcp); res = iSocket.SetOpt(KSoTcpSendWinSize, KSolInetTcp, 0x10000); serverAddr.SetPort(iPort); serverAddr.SetAddress(INET_ADDR(11,11,179,154)); iSocket.Connect(serverAddr,iStatus); User::WaitForRequest(iStatus); Over the iSocket i receive packets of variable size. On very few occurences it happens that such a packet is corrupted. What I would like to do then is to clear all the data that is currently in the iSocket buffer and ready to be read. I have not seen any method of RSocket that allows me to clear the content of the buffer. Does anyone know how to do that? If possible, I would like to avoid using RecvOneOrMore() or similar recv function clear the buffer Thanks

• JBoss Clustered Service that sends emails from txt file

  - by michael lucas

  I need a little push in the right direction. Here's my problem: I have to create an ultra-reliable service that sends email messages to clients whose addresses are stored in txt file on FTP server. Single txt file may contain unlimited number of entries. Most often the file contains about 300,000 entries. Service exposes interface with just two simple methods: TaskHandle sendEmails(String ftpFilePath); ProcessStatus checkProcessStatus(TaskHandle taskHandle); Method sendEmails() returns TaskHandle by which we can ask for ProcessStatus. For such a service to be reliable clustering is necessary. Processing single txt file might take a long time. Restarting one node in a cluster should have no impact on sending emails. We use JBoss AS 4.2.0 which comes with a nice HASingletonController that ensure one instance of service is running at given time. But once a fail-over happens, the second service should continue work from where the first one stopped. How can I share state between nodes in a cluster in such a way that leaves no possibility of sending some emails twice?

• How do I update a progress bar in Cocoa during a long running loop?

  - by Nic

  Hi, I've got a while loop, that runs for many seconds and that's why I want to update a progress bar (NSProgressIndicator) during that process, but it updates only once after the loop has finished. The same happens if I want to update a label text, by the way. I believe, my loop prevents other things of that application to happen. There must be another technique. Does this have to do with threads or something? Am I on the right track? Can someone please give me a simple example, how to “optimize” my application? My application is a Cocoa Application (Xcode 3.2.1) with these two methods in my Example_AppDelegate.m: // This method runs when a start button is clicked. - (IBAction)startIt:(id)sender { [progressbar setDoubleValue:0.0]; [progressbar startAnimation:sender]; running = YES; // this is a instance variable int i = 0; while (running) { if (i++ = processAmount) { // processAmount is something like 1000000 running = NO; continue; } // Update progress bar double progr = (double)i / (double)processAmount; NSLog(@"progr: %f", progr); // Logs values between 0.0 and 1.0 [progressbar setDoubleValue:progr]; [progressbar needsDisplay]; // Do I need this? // Do some more hard work here... } } // This method runs when a stop button is clicked, but as long // as -startIt is busy, a click on the stop button does nothing. - (IBAction)stopIt:(id)sender { NSLog(@"Stop it!"); running = NO; [progressbar stopAnimation:sender]; } I'm really new to Objective-C, Cocoa and applications with a UI. Thank you very much for any helpful answer.

• Inner join on 2 arrays?

  - by russ

  I'm trying to find a solution to the following (I'm thinking with Linq) to the following: I need to pull down certain files from a larger list of files on an ftp server that have a similar file name. For example, we send an order file to some company for processing then they return a response file that we can download. So, I could send them the files "order_123.txt" and "order_456.txt". After a certain amount of time I need to go look for and download the responses for those files that will be named "order_123.resp" and "order_456.resp". The kicker is that in some cases I can have multiple responses in which case they would create "order_123-1.resp" and "order_123-2.resp" and also the files don't get removed from the server. I know this can be accomplished by looping through the files I know I need responses to then loop through all the files on the server until I find files that match but I'm hoping that I don't have to loop through the files on the server more than once. This example may help clarify: I've sent "order_222.txt" and "order_333.txt" they processed them and the ftp server contains: "order_111-1.resp" "order_001.resp" "order_222-1.resp" "order_222-2.resp" "order_333.resp" I need to download the 3rd, 4th, and 5th file. Thanks.

• Loading velocity template inside a jar file

  - by Rafael

  I have a project where I want to load a velocity template to complete it with parameters. The whole application is packaged as a jar file. What I initially thought of doing was this: VelocityEngine ve = new VelocityEngine(); URL url = this.getClass().getResource("/templates/"); File file = new File(url.getFile()); ve = new VelocityEngine(); ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "file"); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_CACHE, "true"); ve.init(); VelocityContext context = new VelocityContext(); if (properties != null) { stringfyNulls(properties); for (Map.Entry<String, Object> property : properties.entrySet()) { context.put(property.getKey(), property.getValue()); } } final String templatePath = templateName + ".vm"; Template template = ve.getTemplate(templatePath, "UTF-8"); String outFileName = File.createTempFile("p2d_report", ".html").getAbsolutePath(); BufferedWriter writer = new BufferedWriter(new FileWriter(new File(outFileName))); template.merge(context, writer); writer.flush(); writer.close(); And this works fine when I run it in eclipse. However, once I package the program and try to run it using the command line I get an error because the file could not be found. I imagine the problem is in this line: ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); Because in a jar the absolute file does not exist, since it's inside a zip, but I couldn't yet find a better way to do it. Anyone has any ideas?

• Rails Binary Stream support

  - by Craig Walker

  I'm going to be starting a project soon that requires support for large-ish binary files. I'd like to use Ruby on Rails for the webapp, but I'm concerned with the BLOB support. In my experience with other languages, frameworks, and databases, BLOBs are often overlooked and thus have poor, difficult, and/or buggy functionality. Does RoR spport BLOBs adequately? Are there any gotchas that creep up once you're already committed to Rails? BTW: I want to be using PostgreSQL and/or MySQL as the backend database. Obviously, BLOB support in the underlying database is important. For the moment, I want to avoid focusing on the DB's BLOB capabilities; I'm more interested in how Rails itself reacts. Ideally, Rails should be hiding the details of the database from me, and so I should be able to switch from one to the other. If this is not the case (ie: there's some problem with using Rails with a particular DB) then please do mention it. UPDATE: Also, I'm not just talking about ActiveRecord here. I'll need to handle binary files on the HTTP side (file upload effectively). That means getting access to the appropriate HTTP headers and streams via Rails. I've updated the question title and description to reflect this.

• Occasional weird Glassfish errors, resolved by a restart?

  - by Pooria

  I'm developing a web app using netbeans with GlassFishv3. Every once in a while when I add a new feature in my app, glassfish starts nagging with stupid errors, after a lot of time wasting and panicking, i restart glassfish and run my application again, then suddenly the errors all go away and my site starts acting correctly. (or in case I have made a real mistake, i receive a reasonable & descriptive error from GF.) [Edit: the rest of the question was revealed to have been my own mistake.] But the problems don't end there. Recently, i added the ability to write comments in a (JSF) page, after the user submits their comment, i add it to the database and redirect to the same page, so that hopefully the page refreshes with the new comment, but it wont! The underlying Mysql database shows that the new comment has been added, but the page just wont show the new comment! I've tried everything (e.g. deleting browser cache, using different browsers) but only after restarting GF is when the page shows the new comment! Do you have any idea what the problem could be? Could this be a Glassfish bug? What i am using: JSF2, EJB3.1, JPA, MySql

• How does static code run with multiple threads?

  - by Krisc

  I was reading http://stackoverflow.com/questions/1511798/threading-from-within-a-class-with-static-and-non-static-methods and I am in a similar situation. I have a static method that pulls data from a resource and creates some runtime objects based on the data. static class Worker{ public static MyObject DoWork(string filename){ MyObject mo = new MyObject(); // ... does some work return mo; } } The method takes awhile (in this case it is reading 5-10mb files) and returns an object. I want to take this method and use it in a multiple thread situation so I can read multiple files at once. Design issues / guidelines aside, how would multiple threads access this code? Let's say I have something like this... class ThreadedWorker { public void Run() { Thread t = new Thread(OnRun); t.Start(); } void OnRun() { MyObject mo = Worker.DoWork("somefilename"); mo.WriteToConsole(); } } Does the static method run for each thread, allowing for parallel execution?

• Working with complex objects in Prevayler commands

  - by alexantd

  The demos included in the Prevayler distribution show how to pass in a couple strings (or something simple like that) into a command constructor in order to create or update an object. The problem is that I have an object called MyObject that has a lot of fields. If I had to pass all of them into the CreateMyObject command manually, it would be a pain. So an alternative I thought of is to pass my business object itself into the command, but to hang onto a clone of it (keeping in mind that I can't store the BO directly in the command). Of course after executing this command, I would need to make sure to dispose of the original copy that I passed in. public class CreateMyObject implements TransactionWithQuery { private MyObject object; public CreateMyObject(MyObject business_obj) { this.object = (MyObject) business_obj.clone(); } public Object executeAndQuery(...) throws Exception { ... } } The Prevayler wiki says: Transactions can't carry direct object references (pointers) to business objects. This has become known as the baptism problem because it's a common beginner pitfall. Direct object references don't work because once a transaction has been serialized to the journal and then deserialized for execution its object references no longer refer to the intended objects - - any objects they may have referred to at first will have been copied by the serialization process! Therefore, a transaction must carry some kind of string or numeric identifiers for any objects it wants to refer to, and it must look up the objects when it is executed. I think by cloning the passed-in object I will be getting around the "direct object pointer" problem, but I still don't know whether or not this is a good idea...

• How can I convert seconds to minutes in jQuery while updating an element with the current time?

  - by pghtech

  So I see a number of ways to display allot of seconds in a (static) hr/min/sec. However, I am trying to produce a visual count down timer: $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); My counter is reduced inside a SetInterval that triggers ever 1 second: //....... var counter = redirectTimer; jQuery('#WarningDialogMsg').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); //........ SetInternval( function() { counter -= 1; secCounter = Math.floor(counter % 60); minCounter = Math.floor(counter / 60); //....... $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); }, 1000) It is a two minute counter but I don't want to display 120 seconds. I want to display 1 : 59 (and counting down). I have managed to get it to work using the above, but my main question is: is there a more elegant way to accomplish the above? (note: I am redirecting once "counter == 0").

• What is the Proper approach for Constructing a PhysicalAddress object from Byte Array

  - by Paul Farry

  I'm trying to understand what the correct approach for a constructor that accepts a Byte Array with regard to how it stores it's data (specifically with PhysicalAddress) I have an array of 6 bytes (theAddress) that is constructed once. I have a source array of 18bytes (theAddresses) that is loaded from a TCP Connection. I then copy the 6bytes from theAddress+offset into theAddress and construct the PhysicalAddress from it. Problem is that the PhysicalAddress just stores the Reference to the array that was passed in. Therefore if you subsequently check the addresses they only ever point to the last address that was copied in. When I took a look inside the PhysicalAddress with reflector it's easy to see what's going on. public PhysicalAddress(byte[] address) { this.changed = true; this.address = address; } Now I know this can be solved by creating theAddress array on each pass, but I wanted to find out what really is the best practice for this. Should the constructor of an object that accepts a byte array create it's own private Variable for holding the data and copy it from the original Should it just hold the reference to what was passed in. Should I just created theAddress on each pass in the loop

• How to calculate the height of the text rectangle from an NSString?

  - by mystify

  I know there is this one: sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: But since the CGSize always has the same height and doesn't adjust to any shrinked text or whatsoever, the CGSize is not telling how heigh the text is. Example: Make a UILabel with 320 x 55 points and put a loooooooooooooong text in there. Let the label shrink the text down. Surprise: CGSize.height remains the same height even if the text is so tiny that you need a microscope. Ok so after banging my head against my macbook pro which is half way broken now, the only think that can help is that nasty actualFontSize. But the font size is in pica I think, it's not really what you get on the screen, isn't it? When that font size is 10, is my text really 10 points heigh at maximum? Once in a while I tried exactly that, and as soon as the text had a y or some character that extends to below (like that tail of an y does), it is out of bounds and the whole text is bigger than 10 points. So how would you calculate the real text height for a single line uilabel without getting a long beard and some hospital experience?

• how to get access to private members of nested class?

  - by macias

  Background: I have enclosed (parent) class E with nested class N with several instances of N in E. In the enclosed (parent) class I am doing some calculations and I am setting the values for each instance of nested class. Something like this: n1.field1 = ...; n1.field2 = ...; n1.field3 = ...; n2.field1 = ...; ... It is one big eval method (in parent class). My intention is -- since all calculations are in parent class (they cannot be done per nested instance because it would make code more complicated) -- make the setters only available to parent class and getters public. And now there is a problem: when I make the setters private, parent class cannot acces them when I make them public, everybody can change the values and C# does not have friend concept I cannot pass values in constructor because lazy evaluation mechanism is used (so the instances have to be created when referencing them -- I create all objects and the calculation is triggered on demand) I am stuck -- how to do this (limit access up to parent class, no more, no less)? I suspect I'll get answer-question first -- "but why you don't split the evaluation per each field" -- so I answer this by example: how do you calculate min and max value of a collection? In a fast way? The answer is -- in one pass. This is why I have one eval function which does calculations and sets all fields at once.

• Downloading a picture via urllib and python.

  - by Mike

  So I'm trying to make a Python script that downloads webcomics and puts them in a folder on my desktop. I've found a few similar programs on here that do something similar, but nothing quite like what I need. The one that I found most similar is right here (http://bytes.com/topic/python/answers/850927-problem-using-urllib-download-images). I tried using this code: >>> import urllib >>> image = urllib.URLopener() >>> image.retrieve("http://www.gunnerkrigg.com//comics/00000001.jpg","00000001.jpg") ('00000001.jpg', <httplib.HTTPMessage instance at 0x1457a80>) I then searched my computer for a file "00000001.jpg", but all I found was the cached picture of it. I'm not even sure it saved the file to my computer. Once I understand how to get the file downloaded, I think I know how to handle the rest. Essentially just use a for loop and split the string at the '00000000'.'jpg' and increment the '00000000' up to the largest number, which I would have to somehow determine. Any reccomendations on the best way to do this or how to download the file correctly? Thanks!

• Full complete MySQL database replication? Ideas? What do people do?

  - by mauriciopastrana

  Currently I have two Linux servers running MySQL, one sitting on a rack right next to me under a 10 Mbit/s upload pipe (main server) and another some couple of miles away on a 3 Mbit/s upload pipe (mirror). I want to be able to replicate data on both servers continuously, but have run into several roadblocks. One of them being, under MySQL master/slave configurations, every now and then, some statements drop (!), meaning; some people logging on to the mirror URL don't see data that I know is on the main server and vice versa. Let's say this happens on a meaningful block of data once every month, so I can live with it and assume it's a "lost packet" issue (i.e., god knows, but we'll compensate). The other most important (and annoying) recurring issue is that, when for some reason we do a major upload or update (or reboot) on one end and have to sever the link, then LOAD DATA FROM MASTER doesn't work and I have to manually dump on one end and upload on the other, quite a task nowadays moving some .5 TB worth of data. Is there software for this? I know MySQL (the "corporation") offers this as a VERY expensive service (full database replication). I am just wondering what people out there do. The way it's structured, we run an automatic failover where if one server is not up, then the main URL just resolves to the other server.

• Change the playback rate of a track in real time on Android

  - by android_dev

  Hello, I would like to know if somebody knows a library to changing the playback rate of a track in real time. My idea is to load a track and change its playback rate to half or double. Firstly, I tried with MusicPlayer but is was not possible at all and then I tried with SoundPool. The problem is that with SoundPool I can´t change the rate once the track is loaded. Here is the code I am using (proof of concept): float j = 1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.Button01); b.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { j = (float) (j +.5); } }); AssetFileDescriptor afd; try { SoundPool sp = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); afd = getAssets().openFd("wav/sample.wav"); int id = sp.load(afd, 1); sp.play(id, 1, 1, 1, 0, j); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } When I press the button, the playback rate should increase but it does not happen. Any idea of how change the rate in real time? Thanks in advance.

• Android: How do I make a video splash screen repeat until webview finishes loading the url?

  I would like to make a small video (about 4 seconds) repeat until webview finishes loading the desired URL in the background. Right now the video plays once, then a blank black screen comes up until the page loads. I'm still pretty new to this... Thanks in advance for any help!

• Alpha animation bug on button

  - by RaiderJ

  I have animations that fade in a Button (alpha from 0 to 1) and fade out a button (alpha from 1 to 0). This part is all working fine. Button A triggers the fade in of Button B. Button B triggers the fade out of itself. Button B totally covers up Button A. The idea is that Button B contains an image that is used like an information popup. Button A is touched and Button B fades in on top. When Button B is touched it fades itself out again. Initially, Button B's visibility is set INVISIBLE and when the fade in animation is complete, it is set to VISIBLE. When Button B is clicked it fades out and then I set the visibility to INVISIBLE. The problem is that after Button B has faded out, and it is set INVISIBLE, it is still clickable and even though it is not visible, and touches are not received by Button A. I have tried removing Button B from the parent and re-adding it after the animation is completed, and this allows for touches to reach Button A, but only once. After that button B is not longer touchable.

• Working with extra fields in an Inline form - save_model, save_formset, can't make sense of the diff

  - by magicrebirth

  Suppose I am in the usual situation where there're extra fields in the many2many relationship: class Person(models.Model): name = models.CharField(max_length=128) class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through='Membership') class Membership(models.Model): person = models.ForeignKey(Person) group = models.ForeignKey(Group) date_joined = models.DateField() invite_reason = models.CharField(max_length=64) # other models which are unrelated to the ones above.. class Trip(models.Model): placeVisited = models.ForeignKey(Place) visitor = models.ForeignKey(Person) pleasuretrip = models.Boolean() class Place(models.Model): name = models.CharField(max_length=128) I want to add some extra fields in the Membership form that gets displayed through the Inline. These fields basically are a shortcut to the instantiation of another model (Trip). Trip can have its own admin views, but these shortcuts are needed because when my project partners are entering 'Membership' data in the system they happen to have also the 'Trip' information handy (and also because some of the info in Membership can just be copied over to Trip etc. etc.). So all I want to have is two extra fields in the Membership Inline - placeVisited and pleasuretrip - which together with the Person instance will let me instantiate the Trip model in the background... I found out I can easily add extra fields to the inline view by defining my own form. But once the data have been entered, how and when to reference to them in order to perform the save operations I need to do? class MyForm(forms.ModelForm): place = forms.ModelChoiceField(required=False, queryset=Place.objects.all(), label="place",) pleasuretrip = forms.BooleanField(required=False, label="...") class MembershipInline(admin.TabularInline): model = Membership form = MyForm def save_model(self, request, obj, form, change): place = form.place pleasuretrip = form.pleasuretrip person = form.person .... # now I can create Trip instances with those data .... obj.save() class GroupAdmin(admin.ModelAdmin): model = Group .... inlines = (MembershipInline,) This doesn't seem to work... I'm also a bit puzzled by the save_formset method... maybe is that the one I should be using? Many thanks in advance for the help!!!!

• Read file:// URLs in IE XMLHttpRequest

  - by Dan Fabulich

  I'm developing a JavaScript application that's meant to be run either from a web server (over http) or from the file system (on a file:// URL). As part of this code, I need to use XMLHttpRequest to load files in the same directory as the page and in subdirectories of the page. This code works fine ("PASS") when executed on a web server, but doesn't work ("FAIL") in Internet Explorer 8 when run off the file system: <html><head> <script> window.onload = function() { var xhr = new XMLHttpRequest(); xhr.open("GET", window.location.href, false); xhr.send(null); if (/TestString/.test(xhr.responseText)) { document.body.innerHTML="<p>PASS</p>"; } } </script> <body><p>FAIL</p></body> Of course, at first it fails because no scripts can run at all on the file system; the user is prompted a yellow bar, warning that "To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer." But even once I click on the bar and "Allow Blocked Content" the page still fails; I get an "Access is Denied" error on the xhr.open call. This puzzles me, because MSDN says that "For development purposes, the file:// protocol is allowed from the Local Machine zone." This local file should be part of the Local Machine Zone, right? How can I get code like this to work? I'm fine with prompting the user with security warnings; I'm not OK with forcing them to turn off security in the control panel. EDIT: I am not, in fact, loading an XML document in my case; I'm loading a plain text file (.txt).

• Null reference exceptions in .net

  - by Carlo

  Hello, we're having this big problem with our application. It's a rather large application with several modules, and thousands and thousands lines of code. A lot of parts of the application are designed to exist only with a reference to another object, for example a Person object can never exists without a House object, so if you at any point in the app say: bool check = App.Person.House == null; check should always be false (by design), so, to keep using that example, while creating modules, testing, debugging, App.Person.House is never null, but once we shipped the application to our client, they started getting a bunch of NullReferenceException with the objects that by design, should never have a null reference. They tell us the bug, we try to reproduce it here, but 90% of the times we can't, because here it works fine. The app is being developed with C# and WPF, and by design, it only runs on Windows XP SP 3, and the .net framework v3.5, so we KNOW the user has the same operative system, service pack, and .net framework version as we do here, but they still get this weird NullReferenceExceptions that we can't reproduce. So, I'm just wondering if anyone has seen this before and how you fixed it, we have the app running here at least 8 hours a day in 5 different computers, and we never see those exceptions, this only happens to the client for some reason. ANY thought, any clue, any solution that could get us closer to fixing this problem will be greatly appreciated. Thanks!

• Why does a change of Session State provider lead to an ASPx page yielding garbage?

  - by Rory Becker

  I have an aspnet webapp which has worked very well up until now. I was recently asked to explore ways of making it scale better. I found that seperation of database and Webapp would help. Further I was told that if I changed my session providing mechanism to SQLServer, I would be able to duplicate the Web Stack to several machines which could each call back to the state server allowing the load to be distirbuted better. This sounds logical. So I created an ASPState database using ASPNet_RegSQL.exe as detailed in many locations across the web and changed the web.config on my app from: <sessionState mode="InProc" cookieless="false" timeout="20" /> To: <sessionState mode="SQLServer" sqlConnectionString="Server=SomeSQLServer;user=SomeUser;password=SomePassword" cookieless="false" timeout="20" /> Then I addressed my app, which presented me with its logon screen and I duly logged in. Once in I was presented, not with the page I was expecting, but with: I can change the sessionstate back and forth. This problem goes away and then comes back based on which set of configuration I use. Why is this happening?

• C# / XNA - Load objects to the memory - how it works?

  - by carl

  Hello I'm starting with C# and XNA. In the "Update" method of the "Game" class I have this code: t = Texture2D.FromFile( [...] ); //t is a 'Texture2D t;' which loads small image. "Update" method is working like a loop, so this code is called many times in a second. Now, when I run my game, it takes 95MB of RAM and it goes slowly to about 130MB (due to the code I've posted, without this code it remains at 95MB), then goes immediately to about 100MB (garbare colletion?) and again goes slowly to 130MB, then immediately to 100MB and so on. So my first question: Can You explain why (how) it works like that? I've found, that if I change the code to: t.Dispose() t = Texture2D.FromFile( [...] ); it works like that: first it takes 95MB and then goes slowly to about 101MB (due to the code) and remains at this level. I don't understand why it takes this 6MB (101-95)... ? I want to make it works like that: load image, release from memory, load image, release from memory and so on, so the program should always takes 95MB (it takes 95MB when image is loaded only once in previous method).

• Response.Redirect not firing due to code to prevent re-submission

  - by Marco

  I have an event which needs to contact some third party providers before performing a redirect (think 'final payment page on ecommerce site') and hence has some lag associated with its processing. It is very important that these third party providers are not contacted more than once, and sometimes impatient users may try and refresh the page (hence re-submitting the data). The general code structure is: If Session("orderStatus") <> 'processing' Then Session("orderStatus") = 'processing' DoThirdPartyStuffThatTakesSomeTime() Response.Redirect("confirmationPage.asp", True) End If The problem is, if the user refreshes the page, the response.redirect does not happen (even though the rest of the code will run before the redirect from the original submission). It seems that the new submission creates a new thread for the browser which takes precedence - it skips this bit of code obviously to prevent the third party providers being contacted a second time, and since there is no redirect, just comes back to the same page. The whole second submission may have completed before the first submission has finished its job. Any help on how I can still ignore all of the subsequent submissions of the page, but still make the redirect work...? Thanks

• Trouble with custom WPF Panel-derived class

  - by chaiguy

  I'm trying to write a custom Panel class for WPF, by overriding MeasureOverride and ArrangeOverride but, while it's mostly working I'm experiencing one strange problem I can't explain. In particular, after I call Arrange on my child items in ArrangeOverride after figuring out what their sizes should be, they aren't sizing to the size I give to them, and appear to be sizing to the size passed to their Measure method inside MeasureOverride. Am I missing something in how this system is supposed to work? My understanding is that calling Measure simply causes the child to evaluate its DesiredSize based on the supplied availableSize, and shouldn't affect its actual final size. Here is my full code (the Panel, btw, is intended to arrange children in the most space-efficient manner, giving less space to rows that don't need it and splitting remaining space up evenly among the rest--it currently only supports vertical orientation but I plan on adding horizontal once I get it working properly): protected override Size MeasureOverride( Size availableSize ) { foreach ( UIElement child in Children ) child.Measure( availableSize ); return availableSize; } protected override System.Windows.Size ArrangeOverride( System.Windows.Size finalSize ) { double extraSpace = 0.0; var sortedChildren = Children.Cast<UIElement>().OrderBy<UIElement, double>( new Func<UIElement, double>( delegate( UIElement child ) { return child.DesiredSize.Height; } ) ); double remainingSpace = finalSize.Height; double normalSpace = 0.0; int remainingChildren = Children.Count; foreach ( UIElement child in sortedChildren ) { normalSpace = remainingSpace / remainingChildren; if ( child.DesiredSize.Height < normalSpace ) // if == there would be no point continuing as there would be no remaining space remainingSpace -= child.DesiredSize.Height; else { remainingSpace = 0; break; } remainingChildren--; } extraSpace = remainingSpace / Children.Count; double offset = 0.0; foreach ( UIElement child in Children ) { //child.Measure( new Size( finalSize.Width, normalSpace ) ); double value = Math.Min( child.DesiredSize.Height, normalSpace ) + extraSpace; child.Arrange( new Rect( 0, offset, finalSize.Width, value ) ); offset += value; } return finalSize; }
