  • Javascript: sort objects

    - by tom
    function Player() { var score; this.getScore = function() { return score; } this.setScore = function(sc) { score = sc; } } function compare(playerA, playerB) { return playerA.getScore() - playerB.getScore(); } var players = []; players['player1'] = new Player(); players['player2'] = new Player(); Array(players).sort(compare); I have code that is similar to the above. When I step through the code with a debugger, the compare function never gets called and the array isn't sorted. I'm not sure what's wrong with my code?

  • Compile Flex application without debug? Optimisation options for flex compiler?

    - by maoanz
    I have created a simple test application with the following code var i : int; for (i=0; i<3000000; i++){ trace(i); } When I run the application, it's very slow to load, which means the "trace" is running. I check the flash player by right-clicking, the debugger option is not enable. So I wonder if there is an option to put in compiler to exclude the trace. Otherwise, I have to remove manually all the trace in the program. Are there any other options of compiler to optimize the flex application in a maximum way? Thanks

  • Windows Phone 7, download xml over ssl with authentication

    - by Snake
    Hi, I'm trying to download a file from my provider. The url is protected with basic username and password, and everything is sent over ssl. So I try to do this: WebClient proxy = new WebClient(); proxy.DownloadStringCompleted += (o, dscea) => System.Diagnostics.Debugger.Break(); proxy.Credentials = new NetworkCredential("username", "password"); proxy.DownloadStringAsync(new Uri("https://..../.../data.xml")); As you can see I try to validate. The data IS correct, and the code works when I try to download something from twitter. What am I forgetting to connect to this xml file?

  • Freeing a character pointer returns error

    - by Kraffs
    I'm trying to free a character pointer after having used it but it returns a strange error. The error says: "_CrtDbgREport: String too long or IO Error" The debugger itself returns no errors while compiling. The code currently looks like this: void RespondToUser(SOCKET client, SOCKET server) { char buffer[80]; char *temp = malloc(_scprintf("HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME)); sprintf(temp, "HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME); send(client, temp, strlen(temp), 0); closesocket(client); free(temp); ListenToUsers(server); } The problem only occurs when I try to free the temp pointer from the memory and not otherwise. What might be causing this?

    Hi This may be very simple question,But please help me. i wanted to know what exactly happens when i call new & delete , For example in below code char * ptr=new char [10]; delete [] ptr; call to new returns me memory address. Does it allocate exact 10 bytes on heap, Where information about size is stored.When i call delete on same pointer,i see in debugger that there are a lot of byte get changed before and after the 10 Bytes. Is there any header for each new which contain information about number of byte allocated by new. Thanks a lot

  • Optimize Apache performance

    - by Phliplip
    I'm looking for ways to optimize our current web server hosted in-house. I'm trying to supply as much relevant information below. Please let me know if you would require additional information in order to assist. Server is running 1 single website, which is an online pizza ordering platform built on Zend Framework (ver1). On traffic stats from the last month aprox 6.000 pageloads per day, concentrated mainly around dinnertime. Around 1500 loads/hour peaks in that period. We recently upgraded from a 2/2mbit aDSL-line to 100/100mbit fiber, and we still have performance issues at dinner time. We assumed the 2mbit was the issue. Website is pretty snappy in low-load periods. Hardware CPU: Intel(R) Xeon(R) CPU 5160 @ 3.00GHz (3000.13-MHz K8-class CPU) Mem: 328M Active, 4427M Inact, 891M Wired, 244M Cache, 623M Buf, 33M Free Swap: 16G Total, 468K Used, 16G Free (6GB physical, 16GB swap) Filesystem Type Size Used Avail Capacity Mounted on /dev/ad7s1a ufs 4.8G 768M 3.7G 17% / devfs devfs 1.0K 1.0K 0B 100% /dev /dev/ad7s1g ufs 176G 5.2G 157G 3% /home /dev/ad7s1e ufs 4.8G 2.8M 4.5G 0% /tmp /dev/ad7s1f ufs 19G 3.5G 14G 19% /usr /dev/ad7s1d ufs 4.8G 550M 3.9G 12% /var Server OS FreeBSD 8.2-RELEASE Software apache-2.2.17 php5-5.3.8 mysql-server-5.5 Apache footprint (example, taken from # top) 31140 www 1 45 0 377M 41588K lockf 2 0:00 0.00% httpd 31122 www 1 44 0 375M 35416K lockf 2 0:00 0.00% httpd 31109 www 1 44 0 375M 38188K lockf 2 0:00 0.00% httpd 31113 www 1 44 0 375M 35188K lockf 2 0:00 0.00% httpd Apache is using the prefork MPM, APC (Alternative PHP Cache).

  • Slime: frame-source-location not implemented / is my sldb Backtrace output normal?

    - by Joel
    I'm debugging my Lisp code in Slime. When the debugger generates the Backtrace it's my understanting that I can hit 'v' on a frame to take me to the source. When I do this on the first (0 index) frame (or indeed any frame) I get frame-source-location not implemented Is this expected, am I missing anything? Edit1: In addition every single frame has "No Locals", is this to be expected too? Edit2: In fact, the whole backtrace output is pretty unintelligible. I'm new to Lisp, so I wasn't initially sure if this was expected or not - but I'm attaching a screenshot, hopefully someone can confirm for me if this looks 'normal':

  • iOS Development: Why isn't my try block catching the exception?

    - by BeachRunnerJoe
    Hi. I have an exception being thrown in my code, but when I wrap it in an try/catch block, it doesn't get caught. The NSLog statement is never called in the catch block. Here's the code... NSInteger quoteLength; [data getBytes:(void *)&quoteLength range:NSMakeRange(sizeof(messageType), sizeof(quoteLength))]; @try { //Debugger stack trace shows an NSException being thrown on this statement NSData *stringData = [data subdataWithRange:NSMakeRange(sizeof(messageType) + sizeof(quoteLength), [data length])]; NSString *quote = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding]; NSLog(@"received quote: %@",quote); [quote release]; } @catch (NSException * e) { NSLog(@"Exception Raised: %@", [e reason]); } Why doesn't it get caught? Thanks so much!

  • UIWebview isn't displaying content I want it to display

    - by Knodel
    In my app I have a UIWebView which loads different rtf files. I use this function to load these files: - (void)loadFile:(NSString*)file { NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* sourceFilePath = [resourcePath stringByAppendingPathComponent:file]; NSURL* url = [NSURL fileURLWithPath:sourceFilePath isDirectory:NO]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [webview loadRequest:request]; } The UIWebView displays nothing. When I enter the debugger, the file string value is which I need, but resourcePath and sourceFilePath values are "nil". What am I doing wrong? Thanks in advance!

  • Linq To Sql Entity Updated from Trigger

    - by James Helms
    I have a Table called Address. I have a Trigger for insert on that table that does some spacial calculations on the address that determines what neighborhood boundaries it is in. address = new Address { Street = this.Street, City = this.City, State = this.State, ZipCode = this.ZipCode, latitude = this.Latitude, longitude = this.Longitude, YearBuilt = this.YearBuilt, LotSize = this.LotSize, FinishedSize = this.FinishedSize, Bedrooms = this.Bedrooms, Bathrooms = this.Bathrooms, UseCode = this.UseCode, HOA = this.HOA, UpdateDate = DateTime.Now }; db.AddToAddresses(address); db.SaveChanges(); In the database i can clearly see that the Trigger ran and updated the neighborhoodID in the address table for the row. I tried to just reload that record to get the assigned id like this: address = (from a in db.Addresses where a.AddressID == address.AddressID select a).First(); In the debugger i can clearly see that the address.AddressID is correct, entity doesn't update in memory. Is there any work around for this?

  • How are clientside security vulnerabilities generally discovered?

    - by Jehjoa
    I mean in operating systems or their applications. The only way I can think of is examine binaries for the use of dangerous functions like strcpy(), and then try to exploit those. Though with compiler improvements like Visual Studio's /GS switch this possibility should mostly be a thing of the past. Or am I mistaken? What other ways do people use to find vulnerabilities? Just load your target in a debugger, then send unexpected input and see what happens? This seems like a long and tedious process. Could anyone recommend some good books or websites on this subject? Thanks in advance.

  • problem loading resource from class library

    - by mishal153
    I have a class library (mylibrary) which has a resource called "close.png". I used redGate reflector to confirm that the resource is actually present in the dll. Now i use mylibrary.dll in a project where i attempt to extract this "close.png" resource like this : BitmapImage crossImage = new BitmapImage(); crossImage.BeginInit(); crossImage.UriSource = new Uri(@"/mylibrary;component/Resources/close.png", UriKind.RelativeOrAbsolute); crossImage.EndInit(); This BitmapImage crossImage is then used like : Button closeButton = new Button() { Content = new System.Windows.Controls.Image() { Source = crossImage }, MaxWidth = 20, MaxHeight = 20 }; On doing this i get no exceptions being thrown but the button shows no image. Also, i do see some exception info if i investigate the button's 'content' in the debugger.

  • MVC 1.0 + EF: Does db.EntitySet.where(something) still return all rows in table?

    - by Dale
    In a repository, I do this: public AgenciesDonor FindPrimary(Guid donorId) { return db.AgenciesDonorSet.Include("DonorPanels").Include("PriceAdjustments").Include("Donors").First(x => x.Donors.DonorId == donorId && x.IsPrimary); } then down in another method in the same repository, this: AgenciesDonor oldPrimary = this.FindPrimary(donorId); In the debugger, the resultsview shows all records in that table, but: oldPrimary.Count(); is 1 (which it should be). Why am I seeing all table entries retrieved, and not just 1? I thought row filtering was done in the DB. If db.EntitySet really does fetch everything to the client, what's the right way to keep the client data-lite using EF? Fetching all rows won't scale for what I'm doing.

  • What would prevent ASP.NET from Output Caching?

    - by amarsuperstar
    I have an ASP.NET application, and am trying to output cache a certain page, however on every request, the debugger is still hitting the OnLoad method and I get a 200 response back. I have placed the output cache directive on a page like so: <%@ OutputCache Duration="60" VaryByParam="None" %> And ensured I have the OutputCache module <add name="OutputCache" type="System.Web.Caching.OutputCacheModule"/> And have also bypassed URL rewriting just in case. I have tried this using Cassini and IIS 5.1 (XP), however the page is not caching at all. Are there any other factors which I have not looked at which could affect this feature? Thanks

  • WCF client hangs on response

    - by JohnIdol
    I have a WCF client (running on Win7) pointing to a WebSphere service. All is good from a test harness (a little test fixture outside my web app) but when my calls to the service originate from my web project one of the calls is extremely slow to deserialize (it takes up to 10 times longer) and not just the first time. I can see from fiddler that the response comes back quickly but then the WCF client hangs on the response itself for more than a minute before the next line of code is hit by the debugger, almost if the client was having trouble deserializing. This happens only if in the response I have a given pdf string, base64 encoded chunked. If for example the service raises a fault (this pdf string is not there) then the response is deserialized immediately. Again, If I send the exact same envelope through Soap-UI or from outside the web project all is good. I am at loss - What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

  • How does everyone set up AWS for PHP with a git workflow while worrying about distributing EC2?

    - by Parris
    Hello, I have been looking for something like heroku but for php, and after much frustration (and almost finding what I need, but not quite) we decided to just go with AWS without any other abstraction. We are using PHP 5.3 (and CakePHP 1.3), and are currently using git. Ubuntu seems like the easiest way to get both of those on there and we will most likely use that. We aren't really going worry about outgoing email. We are using smtp through gmail, but will most likely switch to some other service eventually. I had 3 questions: 1) I have been looking at Zend Server, and I am not quite sure how that is more beneficial than xampp. Perhaps it is not? 2) I suppose to make the application scale we would need multiple instances of some ec2 ami. Then just duplicate it and such. The question then becomes how do we make sure all EC2 instances are up to date? 3) I understand the concept of load balancing to some degree. I understand that in 1 region you select a bunch of servers and have it load balance across them. The question then becomes well how about world wide? How do I make it so that traffic is directed to the correct ec2 server? I have heard of route 53, and tried signing up for that, but nothing appears in my control panel. Also perhaps it is just a DNS thing with my domain registrar? AHHH... some tutorial would be helpful!

  • What are the exact versions of stuff you had to install in order to be able to step-debug a Scala pr

    - by Alex R
    How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence the second part of my question, which is really the most important part: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

  • Flex: DateField how to get the value?

    - by Yevgeny
    I' m trying to use the DateField control. I can set the current value using the selectedDate field. Adobe says: "Selecting the currently selected date in the control deselects it, sets the selectedDate property to null", so when user selects other date the selectedDate = null. How do I can get the current selected value? I only saw in the debugger that DateField's text property contains the string with selected date? Do I need to parse it back? 10x in advance yevgeny

  • Why does casting a NaN to a long yield a valid result?

    - by brainimus
    In the sample code below I am dividing by zero which when I step through it with the debugger the (dividend / divisor) yields an Infinity or NaN (if the divisor is zero). When I cast this result to a long I get a valid result, usually something like -9223372036854775808. Why is this cast valid? Why doesn't it stop executing (throw an exception for example) rather than assign an arbitrary value? double divisor = 0; double dividend = 7; long result = (long)(dividend / divisor);

    Hi, I need to put WCHAR[] to std::cout ... It is a part of PWLAN_CONNECTION_NOTIFICATION_DATA passed from Native Wifi API callback. I tried simply std::cout << var; but it prints out the numeric address of first char. the comparision (var == L"some text") doesn't work either. The debugger returns the expected value, however the comparision returns 0. How can I convert this array to a standard string(std::string)? Thanks in advance
