• FTP client to zip before upload and unzip on the server after upload

  - by Ronaldo Junior

  I am always working with some big websites that is annoying to upload given the number of small files. I use Filezilla but am happy to buy some commercial solution if there is one out there that can zip the files before upload and then unzip it after upload. Its a pain to have to manually do that all the time. If someone know of any ftp client or extension for Filezilla or other that would do that... I sent an email to the support for CuteFTP and WSFtp - no answer so far... I know FTP protocol does not allow this command - thats why Im asking for a extension (if anyone know) or a free or commercial FTP client that do the job...

• How do I sum up weighted arrays in PHP?

  - by christian studer

  Hod do I multiply the values of a multi-dimensional array with weigths and sum up the results into a new array in PHP or in general? The boring way looks like this: $weights = array(0.25, 0.4, 0.2, 0.15); $values = array ( array(5,10,15), array(20,25,30), array(35,40,45), array(50,55,60) ); $result = array(); for($i = 0; $i < count($values[0]); ++$i) { $result[$i] = 0; foreach($weights as $index => $thisWeight) $result[$i] += $thisWeight * $values[$index][$i]; } Is there a more elegant solution?

• Reading Character from Image

  - by Chinjoo

  I am working on an application which requires matching of numbers from a scanned image file to database entry and update the database with the match result. Say I have image- employee1.jpg. This image will have two two handwritten entries - Employee number and the amount to be paid to the employee. I have to read the employee number from the image and query the database for the that number, update the employee with the amount to be paid as got from the image. Both the employee number and amount to be paid are written inside two boxes at a specified place on the image. Is there any way to automate this. Basically I want a solution in .net using c#. I know this can be done using artificial neural networks. Any ideas would be much appreciated.

• Can a DataTemplate be a Page?

  - by dthrasher

  I'm using the MVVM pattern to create a WPF standalone application. My program compiles in Visual Studio 2008, but I frequently get warnings in the editor for my DataTemplates. In my MainWindow.xaml, I've defined the following DataTemplate: <DataTemplate DataType="{x:Type ViewModels:TagViewModel}"> <Views:TagView /> </DataTemplate> Where "TagView" is derived from a Page, rather than an ordinary UserControl. This causes the following message to appear every time I reload the designer in Visual Studio: "Could not create an instance of type 'TagView'. Yet the solution compiles fine and the program seems to work properly. Is this a bug in the Visual Studio 2008 editor? Or am I doing something wrong?

• Convert Hexadecimal String to Data

  - by AriX

  Hi Stack Overflow, I have found a whole lot of different solutions to this problem, but not all of them work, and a lot of them seem somewhat hacky and inefficient. Basically I have a string of hexadecimal data (i.e. "55 AA 41 2A 00 94 55 AA BB BB 00 FF") which I would like to convert to raw data. What is the best way to do this? UPDATE: Vicky's solution worked great for me, but I changed it to work with hexadecimal strings that don't have spaces in between and changed the style a bit. int i = 0; char *hexString = "55AA412A009455AABBBB00FF" char *hexPtr = hexString; unsigned int *result = calloc(strlen(hexString)/2 + 1, sizeof *result); while (sscanf(hexPtr, "%02x", &result[i++])) { hexPtr += 2; if (hexPtr >= hexString + strlen(hexString)) break; } return result;

• How to automatically change a parameter in Reporting Services when another is changed?

  - by Victor Rodrigues

  I have a 'Product' parameter in my report. Depending on the product the user chooses, it will call the report generator stored procedure from a different data source. Looking at this article, I've found how to do the first part of this solution. I've created two internal parameters, Server and Database, and the connection string will use them to connect to the right database. But I need to set this two parameters when the user chooses a product. How could I do this? (If @Product = X) = @Server = Y, @Database = Z

• Java WebApp - Integrate a Payment method system

  - by spike07

  I've a java webApp where people can sell their items like in ebay. I need to integrate a payment system and I'm wondering what's the best (from a customer point of view) and easiest to integrate in my app. I was thinking to integrate paypal and require all the sellers to have an account on it. Maybe Google Checkout can be a good option as well, but I don't know if it's used a lot. I think I'll redirect the user to Paypal and then remove the item once I receive the confirmation from paypal that the item has been payed. Would you suggest another easier to integrate/more trusted solution? Thank you

• Paypal subscribe now button

  - by Bharadwaj

  Hi, I have built an information portal in PHP [Something like a recipe book], where the first few recipes are free to access. The advanced recipes are available only to paid members. I intend to use a simple subscribe now paypal button. When the user clicks on this button, he is directed to paypal website and upon payment redirected to my site. How do I collect the payment information from paypal? I do not want to use a wsdl. I need the information to update my user level field [0 for registered users, 1 for paid users] in the users table. Any pointers? Does IPN do the trick for this? Is there a better solution for this? Thanks, Bharadwaj

• Print out PDF with javascript [closed]

  - by Daniel Abrahamsson

  I have a need to print out multiple PDFs with the help of javascript. Is this even possible without rendering each PDF in a separate window and calling window.print()? Basically, I would like to be able to do something like print('my_pdf_url'). Edit After some searching, I have come to the conclusion that there are no other methods than the one I've described above. It is a far from perfect solution, but it works in simple cases. Edit I ended up merging the PDFs to a monster PDF on the server side and then send this single PDF to the user, who can then choose to print it out.

• Use a "User Macro" in .vcproj RelativePath

  - by Tom Leys

  Inside .vcproj files There is a list of all source files in your project. How can we use a macro to specify the path to a source file? If we do this: <File RelativePath="$(Lib3rdParty)\Qt\qtwinmigrate-2.5-commercial\src\qmfcapp.cpp"> </File> The compiler cannot find the folder: qmfcapp.cpp c1xx : fatal error C1083: Cannot open source file: '.\$(lib3rdparty)\qt\qtwinmigrate- 2.5-commercial\src\qmfcapp.cpp': No such file or directory As you can see, our project compiles in several source files from QT. QT lives inside a folder of external libraries, and we don't want hardcode the path from our project to that folder (we have a very large solution)

• how to clone a project on heroku

  - by rails_guy

  I have a project on heroku working fine. Now I want to create same project with different url (same code) as the one I have working now. So that I can give the new url to the customer as a 'test' site. I know in heroku i can just rename the url but I want to completely separate development from test (database wise). What is the best solution? Do I start from scratch? cd into new folder on my machine...clone project from github...make new database -test ...push to heroku...etc. etc.

• Check which nodes of Beowulf HPC cluster system are free from PHP app?

  - by Skuja

  I am working on my diploma thesis project. I have access to 32Node Dell poweredge HPC cluster system with Linux(Debian i think) installed on it. My first goal is to create web (PHP) app where logged users could see free and busy nodes, turn them on and off. I am planning to do something like this - write some cron daemon that would run every 30seconds or other interval, and it could run ping utility for each node to find out if it is on or off, then write results to some file. Then from my web app i could read the info. Will it be a good solution? What existing for node management solutions are there?

• REST API unauthenticated requests exception based on the User-Agent

  - by Shay Tsadok

  Hi All, I am developing a REST API that supports two kinds of authentication protocols: login form authentication - for browser based clients. Simple Basic authentication - for non-browser clients. I developed a flow in which unauthenticated requests redirected to the "login form", the problem is that this is an undesired behavior for non-borwser clients! I thought to solve it by decide according to the "User-Agent" what to do: browsers will be redirected to the "login form" and non-browser clients will get the standard 401:Basic Authentication. A. What do you think about this solution? B. Is there a standard way in Java to check if the request came from browser, or do i need to develop this kind of mechanism by my own? Thanks in advance!

• Action script 3 bitmap glitch, alpha fade in out

  - by user150946

  I have actually solved this problem but it was a weird one so I will post it and my solution. I had a movie clip with several children each of which had it's own alpha settings. It also had a bitmap child object with a masked movie clip sitting on top of it. I was fading in and out the parent movie clip and was getting some odd results all of the alpha settings of the children were being removed and the bitmap was glitching and showing the contents of the masked object that was above it. The problem was that my alpha value for fully opaque was 100 (as in AS2) not 1 (as per AS3). It took me ages to work this out so hopefully this helps someone else.

• Integrating Facebook and example.com

  - by user366292

  I'm creating web site where you can add idea and comment it. Last week I have been looking for Facebook integration. So you can post idea from Facebook or Example.com. You should also be able to comment ideas from Facebook and Example.com. Two interfaces, one result. Is that possible? And is the Facebook application only solution? What about Facebook group wall? -- UPDATE I have Facebook and Example.com. I would like to have full integration between those. Messages and comments sent from Facebook shows on Example.com and vice versa.

• How would you start automating my job? - Part 2

  - by Jurily

  (Followup to this question) After surviving the first wave of incoming shipments (9 hours of copy/paste), I now believe I have all the requirements. Here is the updated workflow: Monkey collects email attachments (4 Excel spreadsheets, 1 PDF) Monkey creates central database, does complex calculations (right now this is also an Excel spreadsheet) Monkey sends data to two bosses, who set the retail prices independently; first one to reply wins Monkey sends order form to our other warehouses, also Excel Monkey sends spreadsheets to VIP customers, carefully sanitized and formatted (4 different discount categories) Jurily enters the data into the accounting system. I've given up on automating this part, there's too much business logic involved, and the database is a pile of sh^W legacy My question: What technologies would you use for a quick and dirty solution? I'm mostly sold on C#, but coming from a Linux/C++ background, I'm horribly confused about my choices in Microsoft-land. For bonus points: How would you redesign the whole system from the ground up? P.S. in case you were wondering, my job title is System Administrator.

• Touching an object in a tweened animation?

  - by Michael

  I'm having trouble porting a simple game I developed for the iPhone over to Android. The game has an animated ball which moves from Point A to Point B. The user must touch the ball before it reaches point B or lose the game. This was easy to implement on the iPhone using Core Animation since I could locate the current position of the ball by accessing its animation layer. In Android, I attempted to recreate the game using tweened animation and represented the ball as a Drawable. My issue is that I can't determine if the user is touching the spot because the Drawable apparently bounds do not update as the ball visually moves - making the program think the ball is always in its original position. While searching these forums I saw an Android team dev. confirm that you can't get the current location in a tweened animation but offered no solution for a workaround. Can I accomplish this on the Android using my current approach? If not, what approach should I use? Best regards, Michael

• What's the best Java-based forum software?

  - by SamS

  Somebody asked about .NET-based forum software here: http://stackoverflow.com/questions/11046/forum-software-recommandations-net Now I have a similar question but I prefer Java. I'm interested in building a community site so I'd like to know my options. It doesn't have to be free but it needs to be something a normal engineer can afford. Thanks! Update: I prefer a Java-based solution because I'm a Java developer and I figure that it would be easier for me to customize it or modify its code when necessary. I know that PHP forums such as phpBB and vBulletin are very popular but I wouldn't want to touch PHP code.

• HTML Rendering Engine as a Java Control

  - by SvrGuy

  Hi All, We have a client side application (Java/Swing) that we need an HTML rendering control for. What I want to find is the most widely adopted, most heavily developed, easiest to deploy solution to get Gecko or WebKit into a Swing app (Needs to run OS X and Windows). The limited (crappy?) JEditPane type solutions are not robust enough for our needs. We would really like to use either WebKit or Gecko. Some libraries seems to exist that would allow this: (QT WebKit) http://trac.webkit.org/wiki/QtWebKit (JRex) [can not post URL because I am new] etc. Whats the best library to achieve this?

• Changing timezone without changing time in Java

  - by Martin

  Hi! I'm receiving a datetime from a SOAP webservice without timzone information. Hence, the Axis deserializer assumes UTC. However, the datetime really is in Sydney time. I've solved the problem by substracting the timezone offset: Calendar trade_date = trade.getTradeDateTime(); TimeZone est_tz = TimeZone.getTimeZone("Australia/Sydney"); long millis = trade_date.getTimeInMillis() - est_tz.getRawOffset(); trade_date.setTimeZone( est_tz ); trade_date.setTimeInMillis( millis ); However, I'm not sure if this solution also takes daylight saving into account. I think it should, because all operations are on UTC time. Any experiences with manipulating time in Java? Better ideas on how to solve this problem?

• In Django, how to create tables from an SQL file when syncdb is run

  - by Sidney

  Hi, How do I make syncdb execute SQL queries (for table creation) defined by me, rather then generating tables automatically. I'm looking for this solution as some particular models in my app represent SQL-table-views for a legacy-database table. So, I've created their SQL-views in my django-DB like this: CREATE VIEW legacy_series AS SELECT * FROM legacy.series; I have a reverse engineered model that represents the above view/legacytable. But whenever I run syncdb, I have to create all the views first by running sql scripts, otherwise syncdb simply creates tables for them (if a view is not found). How do I make syncdb run the above mentioned SQL?

• How to update an element with a List using LINQ and C#

  - by Addie

  I have a list of objects and I'd like to update a particular member variable within one of the objects. I understand LINQ is designed for query and not meant to update lists of immutable data. What would be the best way to accomplish this? I do not need to use LINQ for the solution if it is not most efficient. Would creating an Update extension method work? If so how would I go about doing that? EXAMPLE: (from trade in CrudeBalancedList where trade.Date.Month == monthIndex select trade).Update( trade => trade.Buy += optionQty);

• change extension obfuscate XML file contents

  - by FFish

  I have SlideShowPro, a Flash photo app that loads an XML file with the paths to the images. Now I don't want people to go sniff in the XML file to get to the images. I tried changing the file images.xml to spacer.gif and it seems to work fine. But I would like to know if I would run into any problems changing the extension. btw already used a few techniques to make the images not so accessible, I know there is no bulletproof solution. Obfuscating the XML file is just another trick..

• Best Practice For Referencing an External Module In a Java Project

  - by Greg Harman

  I have a Java project that expects external modules to be registered with it. These modules: Implement a particular interface in the main project Are packaged into a uni-jar (along with any dependencies) Contain some human-readable meta-information (like the module name). My main project needs to be able to load at runtime (e.g. using its own classloader) any of these external modules. My question is: what's the best way of registering these modules with the main project (I'd prefer to keep this vanilla Java, and not use any third-party frameworks/libraries for this isolated issue)? My current solution is to keep a single .properties file in the main project with key=name, value=classhuman-readable-name (or coordinate two .properties files in order to avoid the delimiter parsing). At runtime, the main project loads in the .properties file and uses any entries it finds to drive the classloader. This feels hokey to me. Is there a better way to this?

• Sorting an array in descending order in Ruby.

  - by Waseem

  Hi, I have an array of hashes like following [ { :foo => 'foo', :bar => 2 }, { :foo => 'foo', :bar => 3 }, { :foo => 'foo', :bar => 5 }, ] I am trying to sort above array in descending order according to the value of :bar in each hash. I am using sort_by like following to sort above array. a.sort_by { |h| h[:bar] } However above sorts the array in ascending order. How do I make it sort in descending order? One solution was to do following: a.sort_by { |h| -h[:bar] } But that negative sign does not seem appropriate. Any views?
