  • Calling HttpRequest::getRawRequestMessage() without send()

    - by danielgrad
    I am trying to call getRawRequestMessage() to get the raw HTTP content of the request described by a HttpRequest object, but I notice it always returns an empty string if I don't call send() first. Which kind of defeats my purpose (I want to send the data through other means than the HttpRequest's own send() method). Is there any other way to convert a HttpRequest object to it's raw string equivalent? To give more context: I'm working with a complex class that builds a HttpRequest object and sends requests through it and I want to add a new mode to the class that will work through raw sockets instead. The request is already built in the HttpRequest object and I would like to not have to parse the object manually to generate the HTTP message.

    Just installed Lion today and my PATH env variable is no longer being set by ~/.MacOSX/environment.plist. Did something change? Can't seem to find any info on that or how to fix. Any ideas? Here's the contents of the PLIST: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>PATH</key> <string>/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/usr/X11/bin:/Users/mdi/bin</string> </dict> </plist>

  • Is there a c++ library that provides functionality to execute an external program and read its outpu

    - by BD at Rivenhill
    Basically, I'm looking for something that will allow me to replicate the following Perl code: my $fh = new FileHandle; $fh->open("foo |"); while (<$fh>) { # Do something with this line of data. } This is in the context of Linux, so a library that is specific to Windows will not help. I know how to write a program that does fork/exec/dup2 and all that basic shell-type jazz, but there are some fiddly details involving terminals that I don't feel like messing around with (and I don't have a copy of "Advanced Programming in the UNIX Environment" or a similar reference handy), so I'm hoping that someone has already solved this problem.

  • Dynamic name of NSMutableDictionary?

    - by Bruno
    Hi everyone I load from a txt file many info, and I would like, if possible, to dynamically create NSmutable dictionary with the elements of the txt. For example, each is like that: id of element | date | text What I'm asking is the equivalent of the NSString stringWithFormat:. Can we do the same for an Mutable Dictionary? To be more practical, let's say the NSString *date is equal to "23/12/2009" (for europe). I want to create a dictionary called 23/12/2009 without declaring *23/12/2009 but just something like dictionaryWithFormat: @"%@", date]; I'm stuck on this, and I don't even know if it is possible. If not, what's the best way to approach that? Thanks everyone Regards

  • Efficient way to combine results of two database queries.

    - by ensnare
    I have two tables on different servers, and I'd like some help finding an efficient way to combine and match the datasets. Here's an example: From server 1, which holds our stories, I perform a query like: query = """SELECT author_id, title, text FROM stories ORDER BY timestamp_created DESC LIMIT 10 """ results = DB.getAll(query) for i in range(len(results)): #Build a string of author_ids, e.g. '1314,4134,2624,2342' But, I'd like to fetch some info about each author_id from server 2: query = """SELECT id, avatar_url FROM members WHERE id IN (%s) """ values = (uid_list) results = DB.getAll(query, values) Now I need some way to combine these two queries so I have a dict that has the story as well as avatar_url and member_id. If this data were on one server, it would be a simple join that would look like: SELECT * FROM members, stories WHERE members.id = stories.author_id But since we store the data on multiple servers, this is not possible. What is the most efficient way to do this? Thanks.

  • Windows API Textfield with offset characters

    - by genesys
    Hi there! Is it possible using the Windows API, to create a textfield that lets me offset characters by exact pixels? if so - how? for example, I would like to place two O letters on top of each other, such that they form something like an 8 ? context is an application for a language where most of the glyphs are written left to right, but sometimes some of the glyphs are stacket on top of each other. Windows API because the framework we're using already uses the Windows API for the whole GUI. Thanks!

  • Dotfuscator from .NET 2.0

    - by vasek7
    Is there any chance to see Application Runs on Codeplex with .NET 2.0 application? I explored Dotfuscator is using web service url http://so-s.info/PreEmptive.Web.Services.Messaging/MessagingServiceV2.asmx. Is possible to track application run event manually? Something like add web service reference and call: Dotfuscator.MessageCache messages = new Dotfuscator.MessageCache(); messages.Business.CompanyId = new Guid("3E35F098-CE43-4F82-9E9D-05C8B1046A45"); messages.Application.Id = new Guid("my app guid"); messages.Application.Name = Application.ProductName; messages.Application.Version = Application.ProductVersion; Dotfuscator.MessagingServiceV2 s = new Dotfuscator.MessagingServiceV2(); s.Publish(messages);

  • J2EE/EJB + service locator: is it safe to cache EJB Home lookup result ?

    - by Guillaume
    In a J2EE application, we are using EJB2 in weblogic. To avoid losing time building the initial context and looking up EJB Home interface, I'm considering the Service Locator Pattern. But after a few search on the web I found that event if this pattern is often recommended for the InitialContext caching, there are some negative opinion about the EJB Home caching. Questions: Is it safe to cache EJB Home lookup result ? What will happen if one my cluster node is no more working ? What will happen if I install a new version of the EJB without refreshing the service locator's cache ?

  • Can JAXB store the class name in the XML so that the the deserialize code doesn't need knowledge of the class?

    - by Andrew
    It seems the standard approach for deserializing JAXB XML is to specify the package name when creating the context. Then, JAXB looks up the class based on the root element: JAXBContext jc = JAXBContext.newInstance("com.foo"); Unmarshaller u = jc.createUnmarshaller(); Object o = u.unmarshal(new StringReader("...")); I'm looking for a more flexible approach where I don't have to specify the package name and could still deserialize any object. This would be as simple as JAXB storing the package in the XML, but I can't seem to find out how to do this. I can write the code to do it myself but that would be unpleasant. It would like JAXB to do it, if possible. BTW, I am not using schemas, just Annotations and marshal/unmarshal. Any ideas?

  • Is looking for Wi-Fi access points purely passive?

    - by Aric TenEyck
    Say I carry a Wi-Fi enabled phone or laptop through an area where there are WAPs. Assuming that I don't actively try to connect to them or otherwise interact with them, is it possible for the owner of that WAP to know that I was there? I'm asking this in the context of my earlier question: Looking for MACs on the network I was talking with a friend about my newfound ability to detect phones (and other devices with MAC addresses) on the network, and he pointed out that it might be useful to detect unknown phones on the network; I could use that data to track down anyone who was in my house and brought a Wi-Fi phone with them. So, if I set up a logging fake WAP with no security or encryption, can I glean any useful information about the devices that come into the house? Assuming that the thief doesn't actively try to connect...

  • How to call/use a value converter inverted

    - by Soko
    Is it possible to use a converter the "wrong" way around? In other words: can I swap source and target? Here's an example: I created a simple IValueConverter called NullableDecimalToStringConverter which converts an input if "" into null and a number into decimal. I use it to bind a TextBox in my WPF view to a decimal? property in my ViewModel. In another context I'd like to convert a NullableDecimal into a String in the same way... Is it possible to simply use the existing NullableDecimalToStringConverter inverted? One method is to use the parameter of the converter to tell the converter which way it should convert. But is there a .NET build in way to do such a thing? Another way would be to build a base class with both conversion methods and two separate converter which call the base class methods...

  • How to store Hierarchical K-Means tree for a large number of images, using Opencv?

    - by AquaAsh
    I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

  • Grails: Duplicates & unique constraint validation

    - by rukoche
    OK here is stripped down version of what I have in my app Artist domain: class Artist { String name Date lastMined def artistService static transients = ['artistService'] static hasMany = [events: Event] static constraints = { name(unique: true) lastMined(nullable: true) } def mine() { artistService.mine(this) } } Event domain: class Event { String name String details String country String town String place String url String date static belongsTo = [Artist] static hasMany = [artists: Artist] static constraints = { name(unique: true) url(unique: true) } } ArtistService: class ArtistService { def results = [ [ name:"name", details:"details", country:"country", town:"town", place:"place", url:"url", date:"date" ] ] def mine(Artist artist) { results << results[0] // now we have a duplicate results.each { def event = new Event(it) if (event.validate()) { if (artist.events.find{ it.name == event.name }) { log.info "grrr! valid duplicate name: ${event.name}" } artist.addToEvents(event) } } artist.lastMined = new Date() if (artist.events) { artist.save(flush: true) } } } In theory event.validate() should return false and event will not be added to artist, but it doesn't.. which results in DB exception on artist.save() Although I noticed that if duplicate event is persisted first everything works as intended. Is it bug or feature? :P

    hello first of all i'm kinda new to C# I'm trying to do something like this in a C# winforms application when my app starts, a form starts minimized in the system tray. when i double click it, it opens and sends a request to a qpid broker for some info. then a message is sent back, and received in a listener in my app (i'm not sure code is relevant but i'll post it anyway) namespace MyApp { public class MyListener : IMessageListener { public void MessageTransfer(IMessage m) { //do stuff with m } } } what i'm trying to do is populate a listbox that's in that form with the message received in that function, but i have no idea how to communicate with that specific form from the MessageTransfer function

  • The meaning of tracking in git

    - by user273158
    In an article that has been cited in StackOverflow a few times (e.g. 1) , the author discusses the asymmetry between git push and git pull, and mentions the following: Update: Thanks to David Ongaro, who points out below that since git 1.7.4.2, the recommended value for the push.default option is upstream rather than tracking, although tracking can still be used as a deprecated synonym. The commit message that describes that change is nice, since it suggests that there is an effort underway to deprecate the term “track” in the context of setting this association with the upstream branch in a remote repository. (The totally different meanings of “track” in git branch --track and “remote-tracking branches” has long irritated me when trying to introduce git to people.) What is exactly the difference that he is referring to with: The notion of "tracking" in git branch --track The notion of "tracking" in remote-tracking branches in the last sentence?

  • Data Usage Checker Tools

    - by Lucifer
    Hey All, I am about to begin a project for a new client, and am worried about a few things concerning data usage on their internet plan. We're in an area where most of the major networks don't cover the area, and the ones that do, have very expensive plans, with very low data allowance per month. I need to develop an app, but part of the problem lies with checking database values every 30 seconds. It's pretty important that this check is happening every 30 seconds, as the database is actually updated all day everyday, approx. every 5seconds (apparently). Each row in the database consists of about a page full of text if you were to paste it into MS Word. So, are there any logical ways of minimizing data usage in my case, and also how am I able to see exactly how much data is used just to establish a connection to the database? Are there any tools for this kind of info? Thanks :)

  • Install the proper bitness Visual C++ Runtime Library via a Setup project

    - by chiru_valentin
    Hi all! The context: I have a solution that contains amongh other C# projects, a VC++ project that suports compiling only as x64 or Win32 (but not Any CPU). In order for the application (which in fact is a macro for a third party application) to run, it requires Visual C++ Runtime libraries (x86) or (x64) (The macro will run on both x64 and x86 operating systems.) The problem: I want to create a Visual Studio setup project that would install the macro on both x86 and x64 operating systems, and the problem I have is to specify what Visual C++ Runtime library to use a prerequisite. If both are selected (x64 and x86) than I have a runtime error message when running the setup.exe, as on x86 operating systems you cannot run x64 executables like the Visual C++ Runtime libraries (x64) kit is...(which the setup calls in the back). So I would need a bitness condition, or something like that to tell the setup what bitness version of the Visual C++ Runtime library to try to install...I'm not sure if this is possible, or even where such a code should be placed in the setup. Thank you for the support, Vali

  • Why is Postgres doing a Hash in this query?

    - by Claudiu
    I have two tables: A and P. I want to get information out of all rows in A whose id is in a temporary table I created, tmp_ids. However, there is additional information about A in the P table, foo, and I want to get this info as well. I have the following query: SELECT A.H_id AS hid, A.id AS aid, P.foo, A.pos, A.size FROM tmp_ids, P, A WHERE tmp_ids.id = A.H_id AND P.id = A.P_id I noticed it going slowly, and when I asked Postgres to explain, I noticed that it combines tmp_ids with an index on A I created for H_id with a nested loop. However, it hashes all of P before doing a Hash join with the result of the first merge. P is quite large and I think this is what's taking all the time. Why would it create a hash there? P.id is P's primary key, and A.P_id has an index of its own.

  • how to create a backup of a file once the current one is changed using php

    - by SkyLar
    I'm playing around with file info in php and i'm wondering if its possible to do the following: once a file is changed get the contents of the file, then put the contents of the file into another file. kinda like a "backup system" so once you make a change to the file a duplicate one is created, each change to the original file overwrites the duplicate one. i'm trying to do this with storing the time in the db, is this possible? i don't know what there is to test against? more clearly, i would like to do the following: execute a script once a specifeced file is changed on the server

  • Multiple windows services in a single project = mystery

    - by Remoh
    I'm having a bizarre issue that I haven't seen before and I'm thinking it MUST be something simple that I'm not seeing in my code. I have a project with 2 windows services defined. One I've called DataSyncService, the other SubscriptionService. Both are added to the same project installer. Both use a timer control from System.Timers. If I start both services together, they seem to work fine. The timers elapse at the appropriate time and everything looks okay. However, if I start either service individually, leaving the other stopped, everything goes haywire. The timer elapses constantly and on the wrong service. In other words, if I start the DataSyncService, the SubscriptionService timer elapses over and over. ...which is obviously strange. The setup is similar to what I've done in the past so I'm really stumped. I even tried deleting both service and starting over but it doesn't seem to make a difference. At this point, I'm thinking I've made a simple error in the way I'm defining the services and my brain just won't let me see it. It must be creating some sort of threading issue that causes one service to race when the other is stopped. Here the code.... From Program.cs: static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new DataSyncService(), new SubscriptionService() }; ServiceBase.Run(ServicesToRun); } From ProjectInstaller.designer.cs: private void InitializeComponent() { this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); this.dataSyncInstaller = new System.ServiceProcess.ServiceInstaller(); this.subscriptionInstaller = new System.ServiceProcess.ServiceInstaller(); // // serviceProcessInstaller1 // this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; this.serviceProcessInstaller1.Password = null; this.serviceProcessInstaller1.Username = null; // // dataSyncInstaller // this.dataSyncInstaller.DisplayName = "Data Sync Service"; this.dataSyncInstaller.ServiceName = "DataSyncService"; this.dataSyncInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // subscriptionInstaller // this.subscriptionInstaller.DisplayName = "Subscription Service"; this.subscriptionInstaller.ServiceName = "SubscriptionService"; this.subscriptionInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // ProjectInstaller // this.Installers.AddRange(new System.Configuration.Install.Installer[] { this.serviceProcessInstaller1, this.dataSyncInstaller, this.subscriptionInstaller}); } private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1; private System.ServiceProcess.ServiceInstaller dataSyncInstaller; private System.ServiceProcess.ServiceInstaller subscriptionInstaller; From DataSyncService.cs: public static readonly int _defaultInterval = 43200000; //log4net.ILog log; public DataSyncService() { InitializeComponent(); //log = LogFactory.Instance.GetLogger(this); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Data Sync Service Started", EventLogEntryType.Information); //log.Info("Data Sync Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Data Sync Timer Elapsed.", EventLogEntryType.Information); } private void InitializeComponent() { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // DataSyncService // this.ServiceName = "DataSyncService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } From SubscriptionService: public static readonly int _defaultInterval = 300000; //log4net.ILog log; public SubscriptionService() { InitializeComponent(); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Subscription Service Started", EventLogEntryType.Information); //log.Info("Subscription Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Subscription Service Time Elapsed", EventLogEntryType.Information); } private void InitializeComponent() //in designer { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // SubscriptionService // this.ServiceName = "SubscriptionService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } Again, the problem is that the timer1_elapsed handler runs constantly when only one of the services is started. And it's the handler on the OPPOSITE service. Anybody see anything?

If I comment out the Dispose() code, it works fine. But won't this cause memory leaks? What's the best way to fix the problem?

  • Linq: comparison with nonexisting value should not cause the exception, but it does

    - by Seacat
    Hello, Given I don't know if the parameter will be null or not and I want to use it in the following way: if Param != null then compare with its id if Param == null then compare with null. Something like that: var c = from cat in context.Categories where ParamCat != null && cat.ParentId == ParamCat.Id || ParamCat == null && cat.ParentId == null select c; If ParamCat is null as soon as I try to get something from c (for example c.Count()) it throws the exception. Usually when we use some kind of condition it stop comparison as soon as condition fail especially if we use AND. For example this code will not cause any exception: if (ParamCat != null && cat.ParentId == RaramCat.Id) { } If so, why the linq code above throw exception? (Null reference) Thanks
