  • Joomla mailing list with referral plugin?

    - by Stu
    Hi all I've inherited a Joomla 1.5 site and I am trying to find a Joomla component that will let me add a signup/prizedraw page where people can also recommend the compo to a friend in the one form. Basically 1 - email to go out to our existing database asking them to recommend a friend for the chance to win x prize 2 – they are directed to the form on the website where they enter their details for the prize draw and also have the option to enter a few friends email addresses 3 – the recommender is entered into the draw (signed up), while the recommended friends get a princes square email saying ‘you have been recommended by....to receive exclusive offers etc etc.. click here to enter. Does anybody know if there any plugins out there that does this or is it a hand code jobby. Cheers muchly.

  • Missing System.Core.dll and others on Visual Studio 2010 Project targeting 3.5 Framework

    - by Mark Struzinski
    I just got Visual Studio 2010 installed and running on my development machine (alongside VS 2008). The first thing I did was make a copy of an existing project and convert it up to the VS 2010 project. I told the conversion wizard to leave the project targeting the 3.5 framework. The project compiles and runs just fine in VS 2008. When I go to build it, several of my references are marked as missing (System.Core, System.Xml.Linq, System.Data.DataSetExtensions). When I go to the Add Reference dialog, they are not present. Yet if I view the GAC at C:\Windows\Assembly, I can see the entries there. I have tried converting the projects to 4.0, then back down to 3.5, and also unloading/reloading the projects. Nothing works. Has anyone else ran across this problem?

  • VBA SQL Loop using QODBC

    - by Dan
    I am trying to loop through an existing table (tblSalesOrder) and I need to run through every line (where they relate to that particular customer) and write each line into an SQL statement and execute it. What is the easiest way to go about this procedure? The number of lines will need to be counted prior to data being written via SQL to a QuickBooks database. I can code something similar in php using the code below, but I am unsure how to convert this into a VBA friendly format: $sql_count = "SELECT count(*) FROM tblSalesOrder WHERE Customer='cust_number'"; execute_query($sql_count) When the above value is greater than 0, the vba code should loop through the queries. Thanks everyone

  • What is the most efficient way to list all of the files in a directory (including sub-directories)?

    - by prometheus
    I am writing a servlet which will examine a directory on the server (external to the web container), and recursively search for certain files (by certain files, I mean files that are of a certain extension as well as a certain naming convention). Once these files are found, the servlet responds with a long list of all of the found files (including the full path to the files). My problem is that there are so many files and directories that my servlet goes extremely slow. I was wondering if there was a best practice or existing servlet for this type of problem? Would it be more efficient to simply compile the entire list of files and do the filtering via js/jquery on the client side?

  • What data structure would be the least painful DataTable replacement?

    - by MatthewMartin
    I'm storing a lot of sorted ~10 row 2 column/key value pairs in ASP.NET cache-- they're the data for dropdownlists. Right now they are all DataTables, which isn't very space efficient (the rule of thumb is 10x increase in size when data is strored in a dataset). Old Code DataTable table = dataAccess.GetDataTable(); dropDownList.DataSource = table; Hoped for new Code Unknown data = dataAccess.GetSomethingMoreSpaceEfficient(); dropDownList.DataSource = data; What pre-existing datastructures are similar enough to DataTable that would minimize code breakage and reduce the serialized size when stored in ASP.NET cache?

  • .gitignore not working for me

    - by John Grey
    Hi, I'm trying to create a new git repository from existing folder. I've created a .gitignore file in the root of the folder. But if I say 'git add *' 'git commit' 'git push' files that should be ignored still get commited to the remote repository. I'm on Windows. Also I've bought a license for SmartGIT. It also seems to ignore .gitignore. I have to manually select which new files to commit. What am I doing wrong?

  • How to have Load balanced web services sending messages with nservicebus to multiple subscribers ?

    - by Mrt
    I have load balanced web servers, that with the existing code base, handles when a user logs into the site. I would like to send a broadcast message to any applications that have subscribed saying 'hey x logged in' ? So have many web servers and many applications subscribing. How does discovery work/configuration work with nservicebus ? Should each application know about each web server and subscribe individually or is this where the distributer comes in, so web servers all send to the 1 distributer and all application subscribe to single distributer and the distributer relays the message ? I've tried to research this, but having troubles. Thanks MrT

  • Website image caching with Apache

    - by Piskvor
    How can I get static content on Apache to be {cached by browser} and not {checked for freshness {with every request}}? I'm working on a website hosted on Apache webserver. Recently, I was testing something with headers (Content-Type for different types of content) and saw a lot of conditional requests for images. Example: 200 /index.php?page=1234&action=list 304 /favicon.ico 304 /img/logo.png 304 /img/arrow.png (etc.) Although the image files are static content and are cached by the browser, every time an user opens a page that links to them, they are conditionally requested, to which they send "304 Not Modified". That's good (less data transferred), but it means 20+ more requests with every page load (longer page load due to all those round-trips, even with Keep-Alive and pipelining enabled). How do I tell the browser to keep the existing file and not check for newer version? EDIT: the mod_expires method works, even with the favicon.

  • Custom components vs default components in GUI Design. Which is more practical? (.NET)

    - by AlexRednic
    Ok, so is it better to create my own components (Either inherit them from existing ones or creating them from scratch) or to use the ones that come by default? I'm asking this under the umbrella of scalability, overhead and other factors that my contribute on each of the choices. UPDATE: Sorry if I'm to vague. I don't really know how to explain myself better. Isn't it a good idea to inherit each default component? For example what if I'm to design a rather large application and for example i need to change the display format on a DateTimePicker. Wouldn't it better to think ahead and inherit it and use the inherited component instead of the defaults? But, wouldn't it add a lot of overhead in small applications?

  • when to use StringBuilder in java

    - by kostja
    It is supposed to be generally preferable to use a StringBuilder for String concatenation in Java. Is it always the case? What i mean is : Is the overhead of creating a StringBuilder object, calling the append() method and finally toString() smaller then concatenating existing Strings with + for 2 Strings already or is it only advisable for more Strings? If there is such a threshold, what does it depend on (the String length i suppose, but in which way)? And finally - would you trade the readability and conciseness of the + concatenation for the performance of the StringBuilder in smaller cases like 2, 3, 4 Strings?

  • What's causing "Unable to retrieve native address from ByteBuffer object"?

    - by r0u1i
    As a very novice Java programmer, I probably should not mess with that kind of things. Unfortunately, I'm using a library which have a method that accepts a ByteBuffer object and throws when I try to use it: Exception in thread "main" java.lang.NullPointerException: Unable to retrieve native address from ByteBuffer object Is it because I'm not using a non-direct buffer? edit: There's not a lot of my code there. The library I'm using is jNetPcap, and I'm trying to dump a packet to file. My code takes an existing packet, and extract a ByteBuffer out of it: byte[] bytes = m_packet.getByteArray(0, m_packet.size()); ByteBuffer buffer = ByteBuffer.wrap(bytes); Then it calls on of the dump methods of jNetPcap that takes a ByteBuffer.

  • How to retain one million simultaneous TCP connections?

    - by cow
    I am to design a server that needs to serve millions of clients that are simultaneously connected with the server via TCP. The data traffic between the server and the clients will be sparse, so bandwidth issues can be ignored. One important requirement is that whenever the server needs to send data to any client it should use the existing TCP connection instead of opening a new connection toward the client (because the client may be behind a firewall). Does anybody know how to do this, and what hardware/software is needed (at the least cost)? Thanks in advance for any suggestions.

  • Implementing a live voting system

    - by Will Eddins
    I'm looking at implementing a live voting system on my website. The website provides a live stream, and I'd like to be able to prompt viewers to select an answer during a vote initiated by the caster. I can understand how to store the data in a mySQL database, and how to process the answers. However: How would I initially start the vote on the client-side and display it? Should a script be running every few seconds on the page, checking another page to see if a question is available for the user? Are there any existing examples of a real-time polling system such as what I'm looking at implementing?

  • Maven workspace resolution horked

    - by user237815
    I'm using m2eclipse to manage maven projects. Somehow I did a bad thing, and now the system is behaving as if workspace resolution is disabled. I have several projects that depend on a main project. This project has a version of 4.0-SNAPSHOT, and all the dependent projects reference it in the dependencies section of their poms. Everything was working fine until I created an entirely new project and mistakenly copied the pom from the main project into the new project. Suddenly, all of the dependent projects got the error: "The container 'Maven Dependencies" references non existing library C:\users\myusername.m2\com\mydomain\myproject\4.0-SNAPSHOT\myproject-4.0-SNAPSHOT.jar I zapped the offending new project, but the error remains for all the dependent projects. I've made no changes (to my knowledge) in the main project or any of the dependent projects, so I'm guessing something got changed in the Eclipse environment. Does m2eclipse or Maven itself maintain settings anywhere that I can blow away?

  • What open source document-oriented database system is most mature for Windows usage?

    - by jdk
    After using relational databases as back-end storage all my Windows programming life (currently .NET), I want to experiment with a document-oriented database by this Wikipedia definition; it can be standalone or layered over an existing non-commercial database system. What open source document-oriented database solution would you recommend from your own experience and why? A nice to have would be a .NET provider. Admittedly this is somewhat subjective and potentially argumentative so keep it real folks and I'll do the same - also your answers will be invaluable to others looking into document-oriented databases for the first time on Windows. I'm sure the overall value of your answers will outweigh any biases. Thanks.

  • Using ASP.Net 4.0 for new Dev projects

    - by JBeckton
    I am currently in the early stages of developing a couple web applications, I have not written any code yet as I am still just gathering requirements and scoping things out. I want to target ASP.Net 4.0 winforms as the platform for these apps but I want to make sure there are no glaring issues with this new version before I commit. I understand that if I was porting an existing app from 2.0, 3.5 to 4.0 there may be issues but I am starting from scratch on these projects and plan to write these apps to support the new features of 4.0. Should I wait for the first service pack to come out? Just seems like more work to start with 3.5 now only to go back through and tweak things for 4.0 in just a few months or even before I finish the app. Our servers are Win 2K3 with IIS6 and MS SQL 2000, Should I expect any problems with VS 2010 and MS SQL 2000 in regards to Linq to SQL and EF?

  • Premium Services - Ad blocker legal or illegal?

    - by René
    Ok, maybe thats kind of a stupid question. But let's try to get an answer. I'm building a Desktop Solution for an existing web service. That web service is only available without ads when you pay for a premium account. Would it be illegal when I block this ads in my Desktop Application? When you use this web service over the browser, every user has the chance to block ads with adblocker addons. So why not block this stuff in my Desktop Application?
