  • How to make a CodeIgniter project portable with redirects

    - by Jono
    I would like to set up my codeigniter projects so I can use it in any folder on my webserver. Unfortunately codeigniter requires me to specify the location in several variables of the config. This is a problem for portability. There are 3 places where I see this: 1) $config['base_url'] 2) $config['base_path'] 3) .htaccess RewriteRule So far, I have found the solution to (1) here: http://codeigniter.com/wiki/Automatic_base_url/ I am looking for solutions to (2) and (3), but most importantly (3). Here is an example situation: I set .htaccess to have the RewriteRule as follows: RewriteRule ^(.*)$ /folderA/index.php/$1 [L] Then I go into my repo and check out the project to another folder to make some separate changes. Now I have to update .htaccess to show the following: RewriteRule ^(.*)$ /folderB/index.php/$1 [L] I would like to set it so I dont have to make any config changes when I check out another copy.

  • openCV usage cvFindDominantPoints

    - by rsinha
    Hi, Does anyone know how to use the cvFindDominantPoints API of openCV? I basically have a 1 channel, binary image from which I get a set of contours. Judging from the image, I seem to be getting the correct contours. Now, I am selecting one of these contours to get dominant points of. This contour has about 60 vertices. However, the API call to cvFindDominantPoints is giving me a sequence of points (about 15) that does not even lie on the contour. It is quite far from it. Any insight? my usage: CvSeq *dominantpoints = cvFindDominantPoints(targetSeq, tristorage, CV_DOMINANT_IPAN, 7, 9, 9, 150);

  • Is JavaFx suitable for creating online multiplayer board/card games?

    - by Piniu
    In JavaFx i can easy create animations, moving pieces etc., but as far as i see there is better to write program logic and communication in java. Worst i see at the moment is calling javafx part as a result of data incoming from server. Is there any convenient way to do it or its better to change to other technology (flex, qt?) assuming it is not important if program will run in browser or outside as a standalone application? I just started to learn javafx but can drop it and move to other technology and consider c++ + wxWidgets or Qt which im more comforatable with.

  • Prepopulate drop-box according to another drop-box choice in Django Admin

    - by onorua
    I have models like this: class User(models.Model): Switch = models.ForeignKey(Switch, related_name='SwitchUsers') Port = models.ForeignKey(Port) class Switch(models.Model): Name = models.CharField(max_length=50) class Port(models.Model): PortNum = models.PositiveIntegerField() Switch = models.ForeignKey(Switch, related_name = "Ports") When I'm in Admin interface and choose Switch from Switches available, I would like to have Port prepopulated accordingly with Ports from the related Switch. As far as I understand I need to create some JS script to prepopulate it. Unfortunately I don't have this experience, and I would like to keep things simple as it possible and don't rewrite all Django admin interface. Just add this functionality for one Field. Could you please help me with my problem? Thank you.

  • How can I create an .xls file with a readwrite password from Delphi

    - by dummzeuch
    I know that it is possible to create .xls files from Delphi using ADO, OLE automation with Excel and even using several commercial libraries. My requirement now is not just creating a new .xls file and adding data to it but in addition protecting it with a password against editing. I guess this would be possible using OLE automation but that would require an Excel installation on the computer and also add all the potential hassle of OLE automation which I would like to avoid. Does any of the other solutions provide the option of password protecting the file? (Yes, I know this is far from secure, but the customer requests it. Just in case it matters: I am using Delphi 2007.)

  • ASP.Net: Scheduled tasks in a shared environment.

    - by UpTheCreek
    This is really an extension of this question, which asked the best way to schedule tasks which need to be performed periodically within ASP.NET in a normal environment. However, I would like to ask this specifically for a Shared Hosting Environment (most of the answers to the previous question would not work in a shared environment as far as I know). One obvious solution would be to have a page which is responsible to performing the tasks on the hosted machine, and call this page from another machine (that you have full control over) using e.g. a windows scheduled task. This is a bit nasty though - are there any better approaches?

  • Using Excel To Read Access Without MS Access On Computer

    - by Tom Clark
    I have written code that joins two table in access, using criteria supplied from drop down lists in excel and then returns the data to a specific location on the spreadsheet (titles already on the sheet). This works fine on my box and others with MS Access on the machine, but the purpose of writing this was to give people (associates) that dont have the MS Access on their machines (which is most of them) to be able to do simple queries to the database. When we try to run this on a machine without MS Access, we are getting the error message "Compile Error: Cant find project or library." Since this works fine on any machine so far that has Access, but not the others I am wondering if this is not possible without the actual Access software. Any help or insight would be appreciated.

  • DEADLOCK_WRAP error when using Berkeley Db in python (bsddb)

    - by JiminyCricket
    I am using a berkdb to store a huge list of key-value pairs but for some reason when i try to access some of the data later i get this error: try: key = 'scrape011201-590652' contenttext = contentdict[key] except: print the error <type 'exceptions.KeyError'> 'scrape011201-590652' in contenttext = contentdict[key]\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in __getitem__\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n', 'File "/usr/lib64/python2.5/bsddb/dbutils.py", line 62, in DeadlockWrap\n return function(*_args, **_kwargs)\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in <lambda>\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n'] I am not sure what DeadlockWrap is but there isnt any other program or process accessing the berkdb or writing to it (as far as i know,) so not sure how we could get a deadlock, if its referring to that. Is it possible that I am trying to access the data to rapidly? I have this function call in a loop, so something like for i in hugelist: #try to get a value from the berkdb #do something with it I am running this with multiple datasets and this error only occurs with one of them, the largest one, not the others.

  • wxHaskell on OS X

    - by Bill
    I want to use wxHaskell on OS X (Snow Leopard, MacBook Pro). I was able to install the library successfully and the script below: module Main where import Graphics.UI.WX main :: IO () main = start hello hello :: IO () hello = do f <- frame [text := "Hello!"] quit <- button f [text := "Quit", on command := close f] set f [layout := widget quit] does result in a window being displayed with a single button, as specified. However, nothing happens when I click the button - I don't even get the visual response of the button turning blue to indicate that it's been depressed (haha, no pun intended). I've heard that you have to run a package called "macosx-app" on wxHaskell binaries to get them to run, but I can't find this anywhere. It's not on my machine or (as far as I can tell) in the WX or wxHaskell distros. Anyone know what I need to do to get this to work?

  • How to track different button clicks with Google Analytics and AJAX?

    - by citronas
    I have several pages, let's call them A, B and C. Each of these pages has a form where the user can type in some information and click a button to send those information to the server. This button click is performed in an UpdatePanel to prevent a full postback. A customer of ours now wants to know how many % of the using visiting each site (A, B and C have different URLs) use this form. (Meaning I need seperate values for A, B and C) How to I track this in Google Analytics? It seems that I have to create a conversion(??) for each page. Is that correct? How must I modify the existing web application to let Google Analytics know, that a user submitted the form. (without the need to redirect thank to xy amount of different thank you pages) The only piece of information I've found so far is this: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55519 Unfortunately, this FAQ entry does not cover my answer.

  • Do you chat online for work purposes?

    - by JBB
    I've worked with folks who are chatting online with their peers, constantly batting around ideas. I've also worked with folks who adamantly refuse and think it's a waste of time. Are online live chatting forums of particular use to you? Why or why not? Internal to your company, or external and world-wide? Does your employer encourage or discourage their use? Update: I see some people are voting this question down, yet so far all the answers have been positive, if with some reservations. If someone has a strong negative opinion (I hate online chatting and think it should be banned etc.) I'd really like to hear why.

  • Is there a decent JSON editor around?

    - by al4nis
    I'm looking for a JSON editor that is able to do syntax checking and outline view. Browser-based editors are not an option as they are clumsy for editing lots of local files. Eclipse plug-in would be ideal, but I would be happy with anything that works. I found only two so far, those in Aptana Studio Pro and Spket IDE (both available as plug-ins for Eclipse). While they have decent outline views, their syntax checking doesn't catch most of the common errors (like missing commas or braces) which makes them almost useless.

  • PEP8: conflict between W292 and W391

    - by seler
    As far as I know in unix it's a good practice to always have blank line at the end of file - or to put it in other words: every line should end with \n. While checking my python code with PEP8 I noticed that it also states that there should be \n at end of file: W292 no newline at end of file JCR: The last line should have a newline. What's strange, it conflicts with W391: W391 blank line at end of file JCR: Trailing blank lines are superfluous. Okay: spam(1) W391: spam(1)\n How it should be? Should I have blank line at the end of file or not?

  • Haskell Syntax: Parse Error On Input

    - by NuNu
    As part of a mini-haskell compiler that I'm writing, I have a function named app. What I want this function to do is take in these arguments epp (App e1 e2). The first step would be to evaluate e1 recursively (epp e1) and check if the output would be an error. If not then evaluate e2 and then call another function eppVals to evaluate the outputs of the calls on e1 and e2 which I defined as v1 and v2 respectively. epp (App e1 e2) | epp e1 /= Error = eppVals v1 v2 | otherwise = Error where v1 = epp e1 v2 = epp e2 <- parse error on input `=' Logically I believe what I have written so far works but I'm getting a parse error on input = where I stated above. Any idea why? My second try epp :: Exp -> Error Val epp (App e1 e2) = (eppVals v1 v2) where v1 = (epp e1) v2 = (epp e2) But now throws Couldn't match expected type Val with actual type Error Val

  • How to support both DataContractSerializer and XMLSerializer for the same contract on the same host?

    - by Sly
    In our production environment, our WCF services are serialized with the XMLSerializer. To do so our service interfaces have the [XMLSerializerFormat] attribute. Now, we need to change to DataContractSerializer but we must stay compatible with our existing clients. Therefore, we have to expose each service with both serializers. We have one constraint: we don't want to redefine each contract interface twice, we have 50 services contract interfaces and we don't want to have IIncidentServiceXml IIncidentServiceDCS IEmployeeServiceXml IEmployeeServiceDCS IContractServiceXml IContractServiceDCS How can we do that? This is a description of what we have tried so far but I'm willing to try completely different approaches: We tried to create all the endpoints by code in our own ServiceHostFactory class. Basically we create each endpoint twice. The problem is that at runtime, WCF complains that the service has two endpoints with the same contact name but with different ContractDescription instances. The message says we should use different contract names or reuse the same ContractDescription instance.

  • What are the characteristics of spaghetti code?

    - by justjoe
    Somebody said that when your PHP Code and application use global variable then it must be a spaghetti code (i assume this). I use wordpress a lot. As far as i know, it's the best thing near a great php software. And it use many global variables to interact between its components. but forget about that, cause frankly, that's the only thing i know. so it's completely biased ;D so just curious, What is the characteristic of spaghetti code ? ps : the only thing i know is wordpress. so, Hopefully, maybe this will help somebody give great answer for somebody who have a little experience on developing full web application on PHP (for example, stack-overflow website)

  • How do I manually log a user in with a MembershipProvider?

    - by Allen
    I'm experimenting with writing my own custom MembershipProvider in asp.net and I want to roll my own login page. We do some fairly special stuff at login time so we can't use the default login control so I need a way to manually log a user in. So far I haven't found anything on how to write your own login control so I'm here, wondering how I can manually log a user in via a MembershipProvider. I've tried Membership.ValidateUser("user", "pass"); and while that does call ValidateUser() on my custom MembershipProvider, and it does return true, it doesn't actually log me in. Btw I'm fairly new to the whole MembershipProvider stuff so if I'm not even on the right wavelength, feel free to let me know.

  • The sieve of Eratosthenes in F#

    - by IVlad
    I am interested in an implementation of the sieve of eratosthenes in purely functional F#. I am interested in an implementation of the actual sieve, not the naive functional implementation that isn't really the sieve, so not something like this: let rec PseudoSieve list = match list with | hd::tl -> hd :: (PseudoSieve <| List.filter (fun x -> x % hd <> 0) tl) | [] -> [] The second link above briefly describes an algorithm that would require the use of a multimap, which isn't available in F# as far as I know. The Haskell implementation given uses a map that supports an insertWith method, which I haven't seen available in the F# functional map. Does anyone know a way to translate the given Haskell map code to F#, or perhaps knows of alternative implementation methods or sieving algorithms that are as efficient and better suited for a functional implementation or F#?

  • Different execution plan for similar queries

    - by Graham Clements
    I am running two very similar update queries but for a reason unknown to me they are using completely different execution plans. Normally this wouldn't be a problem but they are both updating exactly the same amount of rows but one is using an execution plan that is far inferior to the other, 4 secs vs 2 mins, when scaled up this is causing me a massive problem. The only difference between the two queries is one is using the column CLI and the other DLI. These columns are exactly the same datatype, and are both indexed exactly the same, but for the DLI query execution plan, the index is not used. Any help as to why this is happening is much appreciated. -- Query 1 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail AS b WHERE a.DLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a -- Query 2 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail b WHERE a.CLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a

  • Ruby vs Lua as scripting language for C++

    - by bl00dshooter
    I am currently building a game server (not an engine), and I want it to be extendable, like a plugin system. The solution I found is to use a scripting language. So far, so good. I'm not sure if I should use Ruby or Lua. Lua is easier to embed, but Ruby has a larger library, and better syntax (in my opinion). The problem is, there is no easy way I found to use Ruby as scripting language with C++, whereas it's very easy with Lua. Toughs about this? Suggestions for using Ruby as scripting language (I tried SWIG, but it isn't nearly as neat as using Lua)? Thanks.

  • min.js to clear source

    - by dole
    Hi there As far i know until now, the min version of a .js(javascript) file is obtaining by removing the unncessary blank spaces and comments, in order to reduce the file size. My questions are: How can I convert a min.js file into a clear, easy readable .js file Besides, size(&and speed) are there any other advtages of the min.js file. the js files can be encripted? can js be infected. I think the answer is yes, so the question is how to protect the .js files from infections? Only the first question is most important and I'm looking for help on it. TY

  • MySQL calling in Username to show instead of ID!

    - by Jess
    I have a users table, books table and authors table. An author can have many books, while a user can also have many books. (This is how my DB is currently setup). As I'm pretty new to So far my setup is like bookview.php?book_id=23 from accessing authors page, then seeing all books for the author. The single book's details are all displayed on this new page...I can get the output to display the user ID associated with the book, but not the user name, and this also applies for the author's name, I can the author ID to display, but not the name, so somewhere in the query below I am not calling in the correct values: SELECT users.user_id, authors.author_id, books.book_id, books.bookname, books.bookprice, books.bookplot FROM books INNER JOIN authors on books.book_id = authors.book_id INNER JOIN users ON books.book_id = users.user_id WHERE books.book_id=" . $book_id; Could someone help me correct this so I can display the author name and user name both associated with the book! Thanks for the help :)

  • How do you run a uncompiled CGI?

    - by Toast
    I'm going to get right to it. iPage shared hosting. Trying to use mimetex.cgi to render math. Source code is at the link. After preparing everything just as I had with a different shared host (which worked), I get errors. Tech support tells me I need to upload the uncompiled source and use that instead. ??? Rather than going with them just being ignorant and wrong, I'm going to assume I'm missing something. How am I supposed to execute and make use of the uncompiled source code? What the hell is wrong with a hosting service that doesn't support running compiled CGI written in C (as far as I can tell)?

  • Using WCF in .NET how can I make it auto generate SOAP docs like ASMX did?

    - by Hades
    I'm currently writing a web service using WCF in VB.NET. Previous web services I wrote used ASMX but I wanted to learn WCF and so far it's going well. I actually prefer the way WCF does things. One thing I miss however is the way that ASMX used to generate example SOAP requests and responses. It was like getting documentation for free. Is there anyway to auto generate SOAP documentation for WCF? If not, is there any way to generate it in a .NET page using the WSDL?
