• Use of bit-torrent for large file download as an alternative to FTP

  - by questzen

  The company I work for procures large volumes of data and does this by subscribing to FTP locations. I was wondering if it is possible to download the same using a tracker, the major challenge is authentication of the users IMO. Most ftp servers we subscribe to have a restriction of the number of ftp connection attempts. Does any one here have any experience with this? Any advice is welcome. Edit To clarify, we subscribe to third party vendors and access their ftp location using credentials provided by them. The service is not exclusive to us, they do sell their data to several others. If we could be part of the swarm, the download rates would be pretty high without added penalty. The question is about the possibility of achieving this, so that we can put-forth a proposal in those lines. The vendors obviously wouldn't share data to non-subscribers, so that is a constraint.

• Upload image from local into tinyMCE?

  - by M Sach

  I am using tinymce. It works great. But i want the feature in tinymce where user can upload the images from local box/or from public websites. I am using tomcat ,jsps and core java.I found couple of free third party libraries like ibrowser ,imanager,jbimages etc but all of them using PHP which looks like does not fit in my existing project (i dont know PHP but i tried to integrate one of these in my existing project they don't work and gives some weird error.)

• any open source instant messenger?

  - by George2

  Hello everyone, I need to develop an instant messenger (like MSN Messagner, but only simple and basic function is fine), based on .Net (C#). I want to integrate the instant messenger with my current web site user. I want to know any open source (better C#) instant messenger to reference? BTW: some of the users are using internal IP address (behind a gateway or proxy, like 10.10.xxx.xxx) -- so in this scenario two users can not use point to point message transfer if both of them are behind a gateway? And I think I have to develop a server which acts as an intermediate party to transfer message between two users, correct? thanks in advance, George

• SQL COUNT records in table 2 JOINS away

  - by Fred K

  Using MySQL, I have three tables: projects: ID name 1 "birthday party" 2 "soccer match" 3 "wine tasting evening" 4 "dig out garden" 5 "mountainbiking" 6 "making music" batches: ID projectID templateID when 1 1 1 7 days before 2 1 1 1 day before 3 4 2 21 days before 4 4 1 7 days before 5 5 1 7 days before 6 3 5 7 days before 7 3 3 14 days before 8 5 1 14 days before templates: ID message 1 "Hi, I'd like to invite ..." 2 "Dear Sir, Madam, ..." 3 "Can you please ..." 4 "Would you like to ..." 5 "To all dear friends ..." 6 "Does any of you guys ..." I would like to display a table of templates and the number of projects they're used in. So, the result should be: templateID projectCount 1 3 2 1 3 1 4 0 5 1 6 0 I've tried all kinds of SQL queries using various JOINs, but I guess this is too complicated for me. Is it possible to get this result using a single SQL statement?

• Does TCP actually define 'TCP server' and 'TCP clients'? [closed]

  - by mjn

  In the Wikipedia article, TCP communication is explained using the terms 'client' and 'server'. It also uses the word 'peers'. But TCP actually does not define "TCP clients" and "TCP servers" - In the RFC 675 document (SPECIFICATION OF INTERNET TRANSMISSION CONTROL PROGRAM), the word "client" never appears. The RFC explains that TCP is used to connect processes over ports (sockets), and that 'A pair of sockets form a CONNECTION which can be used to carry data in either direction [i.e. full duplex]. Calling the originating party the "client" seems to be common practice. But this client/server communication model is not always applicable to TCP communication. For example take peer-to-peer networks. Calling all processes which open a socket (and wait for incoming connections from peers) "TCP servers", sounds wrong to me. I would not call my uncle's telephone device a "Telephony server" if I dial his phone number and he picks up.

• C++ obtaining milliseconds time on Linux -- clock() doesn't seem to work properly

  - by hasen j

  On Windows, clock() returns the time in milliseconds, but on this Linux box I'm working on, it rounds it to the nearest 1000 so the precision is only to the "second" level and not to the milliseconds level. I found a solution with Qt using the QTime class, instantiating an object and calling start() on it then calling elapsed() to get the number of milliseconds elapsed. I got kind of lucky because I'm working with Qt to begin with, but I'd like a solution that doesn't rely on third party libraries, Is there no standard way to do this? UPDATE Please don't recommend Boost .. If Boost and Qt can do it, surely it's not magic, there must be something standard that they're using!

• Forming a SOAP request message through WSDL

  - by Shahzad

  I'm very new to webservices. I'm trying to figure out how I can formulate a request message (and determine what the response message) would be based on the wsdl description that I have. This is from a third party web service. The WSDL description that I have access to gives me a bunch of information like <types> <message> <operation> etc. But in the examples that I've seen online, it's showing the request mesage within the "soap:envelope" tag. What am I missing? Eventually I'd like to be able to call this webservice using JQuery. But I can't even figure out how to formulate the request message let alone make an ajax call to it. any help would be appreciated.

• Building a user subscription application

  - by Tristan O'Neil

  Hello, I'm trying to come up with the best way to handle user subscription and management for our magazine website. What I want to happen is a user purchases a subscription and they are granted online access of a certain membership role for a certain amount of time depending on how many years they subscribed for. I would also like the system to be able to send out emails when a subscription is almost up. I've seen some third party projects to help accomplish this but I'd prefer to write this from scratch as I want total control over how it works. Any suggestions would be helpful. The main thing I can't figure out is how to have an expiring membership. You must keep track of when the user signed up and how long until they should expire.

• Restricting deletion with NHibernate

  - by FrontSvin

  I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

• Determining if an offset is in between line numbers?

  - by Sophomore

  hi I need to determine if a given selection is in between a start line and an end line. I have an ILineRange and a given offset within the viewport of eclipse. (I need to know, if the selection (from a remote party) was made within the current viewport of the local user. Unfortunately, I cannot get an LineRange from the selection. I must rely on getOffset() and getLength()... Anyone has an idea? I think there is not a clean solution for this, as the offset (or the characters per line vary (new line lines or a big block of comment).

• Can I switch the Visual C++ runtime to another heap?

  - by sharptooth

  My program uses a third party dynamic link library that has huge memory leaks inside. Both my program and the library are Visual C++ native code. Both link to the Visual C++ runtime dynamically. I'd like to force the library into another heap so that all allocations that are done through the Visual C++ runtime while the library code is running are done on that heap. I can call HeapCreate() and later HeapDestroy(). If I somehow ensure that all allocations are done in the new heap I don't care of the leaks anymore - they all go when I destroy the second heap. Is it possible to force the Visual C++ runtime to make all allocations on a specified heap?

• Expected symbol problems with this function declaration

  - by Derek

  I am just getting back into the C programming realm and I am having an issue that I think is linker related. I am using cmake for the first time as well, so that could be adding to my frustration. I have included a third party header file that contains a typedef that my code is trying to use, and it has this line: typedef struct a a_t so my code has a_t *var; //later..... var->member;// this line throws the error which throws the error: dereferencing pointer to incomplete type So am I just missing another include file, or is this a linker issue? I am building this code in QtCreator and using cmake. I can dive on a_t to see that typedef declaration in the included header, but I can't seem to dive on "struct a" itself to see where it's coming from. Thanks

• Which .NET data provider?

  - by worlds-apart89

  I am new to database programming, so I'd like help getting on the right track. I have read that there are Microsoft-defined and third-party data providers for data access. MSDN has information on data providers for SQL Server, OLE DB, ODBC, Oracle, as well as the EntityClient provider (Entity Framework). Which data provider is today's hottest, most-widely used model? Which one is the future? Also, I have seen Linq to SQL tutorials, but what category does L2S fall into?

• Add static const data to a struct already defined

  - by Kyle

  Since static const data inside a class is really just namespace sugar for constants I would think that struct A { float a; struct B { static const int b = a; }; }; would be equivalent to struct A { float a; }; struct A::B { static const int b = a; }; or something similar. Is something like this possible in C++? It would be useful for me to be able to tag class definitions that I'm pulling in from third party libraries with information like this.

• In which document do file specifications belong?

  - by Andrew

  In which document would a file specification belong? Perhaps this file is used as an input to a third-party system. Would it belong in its own document? Or would it be better to put it in the functional or design spec? Or somewhere else? When I say file specification, I mean a description of what format the file is (CSV, fixed width, etc), columns, data types, etc. Also, where should you document how the file is generated? i.e. business rules/algorithms which are used to generate the file.

• Protect value from changies using reflection?

  - by IordanTanev

  Hi, here is the problem case i am writing a little third party library. In this library i have a class like this public class TestClass { public int TestField { get; private set; } public TestClass( ) { TestField = 1; } } Then i have a varialbe form this class like this public TestClass test = new TestClass( ); The problem i am facing is that usnig reflection like this PropertyInfo field = typeof( TestClass ).GetProperty( "TestField" ); field.SetValue( test, 2, null ); programers can change internal value of this class. this will be very bad thing becouse it can crash the hole library. My question is what is the best way to protect my code form such changes.I know i can use some kind of bool flag so tha value can be changed only ones but this is not very good salution is there a better one? Best Regards, Iordan

• What is the accepted way to replace java.util.Date(year,month,day)

  - by dagw

  I'm trying to do something really simple, but starting to realize that dates in Java are a bit of minefield. All I want is to get passed groups of three ints ( a year, a month and a date) create some Date objects, do some simple test on them (along the lines of as date A before date B and after January 1 1990), convert them to java.sql.Date objects and pass them off to the database via JDBC. All very simple and works fine using the java.util.Date(int year,int month,int day) constructor. Of course that constructor is depreciated, and I'd like to avoid using depreciated calls in new code I'm writing. However all the other options to solve this simple problem seem stupidly complicated. Is there really no simple way to do what I want without using depreciated constructors? I know the standard answer to all Java date related questions is "use joda time", but I really don't want to start pulling in third party libraries for such a seemingly trivial problem.

• Is there any memory restrictions on an ASP.Net application? HttpHandler?

  - by tpower

  I have an ASP.Net MVC application that allows users to upload images. When I try to upload a really large file (400MB) I get an error. I assumed that my image processing code (home brew) was very inefficient, so I decided I would try using a third party library to handle the image processing parts. Because I'm using TDD, I wanted to first write a test that fails. But when I test the controller action with the same large file it is able to do all the image processing without any trouble. The error I get is "Out of memory". I'm sure my code is probably using a lot more memory than it needs to but I just want to know why my test passes. The other difference is that I'm using SWFUpload which is not used with the test. Could this be the cause?

• Quick way to get an NSDictionary from an XML NSData representation?

  - by dontWatchMyProfile

  I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

• Beginner servlet question: accessing files in a .war, which path?

  - by Navigateur

  When a third-party library I'm using tries to access a file, I'm getting "Error opening ... file ... (No such file or directory)" even though I KNOW the file is in the WAR. I've tried both packaged (.war) and "exploded" (directory) deployment, and the file is definitely there. I've tried setting full permissions on it too. It's on Unix (Ubuntu). File is war/dict/index.sense and the error is "dict/index.sense (No such file or directory)". It works fine on my Windows computer when running in hosted mode as a GWT app from Eclipse, just not when I transfer it to the Unix machine for deployment. My question is: has anybody experienced this before and/or are there differences in relative path that I should consider i.e. what's the root path for relative file access in a war?

• Multiple System.Web.Extensions assembly in same project?

  - by CL4NCY

  Hi, I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation. Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?
