• mysql PHP query question

  - by camran

  Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

• Content Assist problem in eclipse 3.5

  - by user361996

  I've got a Content Assist problem in eclipse 3.5, which is eclipse-java-galileo-win32.zip. When I press Alt+/(I've changed Ctrl+Space to this) in Java Editor, no assistant tips are shown up. I've solved this problem and I'd like to share my experience. 1 Eclipse--Preferences--General--Keys; 2 Search 'Content Assist'; 3 You'll find that in 'When' Field, the default value is 'in dialogs and window', change it to 'Editing Java Source', then press 'OK' to save; I can not post a image, but here is a link: http://www.freeimagehosting.net/image.php?e0987ea847.png That's All.

• how to create english language dictionary application with python (django)?

  - by sintaloo

  Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

• Class properties vs NSArray / NSDictionary

  - by Frank Martin

  I want a custom class object to hold data and have somehow the feeling that creating about 80 properties is not the best way of doing it. Most of the properties would be bool values, so i'm thinking about creating Arrays (keys / values) or (probably better) a NSDictionary attached to the object for holding the data. Does that make sense or should i stay with the properties? Extra: Are there general pros and cons for the different approaches? And what keywords / concepts do i have to search for to find discussions about that somehow general question? Thanks in advance

• How to find dynamically loaded modules (the static ones) programatically in windows

  - by Ryan Rohrer

  I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

• how to remove error text from the email format checker code?

  - by rdesai

  I have been writing a code for validating forms using javascript/jquery. Following is a code snippet for checking email format. The problem is when I enter invalid email, it recognizes it, but when I go back to this field and enter correct email, the error text still stays even though I have used the 'else' part. How do I remove the error text in this case? if(e1.value!=''){ var emailRegEx = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i; if (document.signupForm.email1.value.search(emailRegEx) == -1) { $("#err_email1").html("Please enter valid email address."); } status=0; } else{ $("#err_email1").html(""); status=1; }

• Django Template - Convert python list into a javascript object

  - by amcashcow

  I am working on a django / python website I have a page where I want to display a table of search results The list of results is passed in to the template as normal I also want to make this list of objects accessible to the javascript code My first solution was just create another view that returned json format. But each page load required calling the query twice. So then I tried only downloading the data using the json view and printing the table using javascript. but this is also not desirable as now the presentation layer is mixed into the javascript code. is there a way to create a javascript object from the python list as the page is rendered?

• Tags php improving database speed and user experience

  - by Doodle

  How did stackOverFlow, excuse me if it wasn't the first implementation of this system. Decide what its initial tags where? I want to provide users with the best experience on my site and am implementing a tags system. I don't care about search engines or any of that. I just care about my users. Does any one have any advice about things that have failed or succeeded when they allowed users to tag things? Does any one know some good resources about the methodologies of user tagging? Does any one know some good resources about implementing a tags system from a programming perspective, database structures, theories, etc ? I'll give my check to who ever I feel points me in the best direction on the subject.

• Something wrong with redirects on my Joomla 1.5.18 site

  - by fuzzy lollipop

  My Joomla 1.5.18 site, I enabled login, when I click login the page I get sent to is NOT styled with CSS. If I login it redirects to the home page and it is not styled anymore either. It looks like it is recursively appending stuff to the URL incorrectly. http://www.myjoomlasite.org/index.php/index.php/login if I click on home page or login links it keeps putting more and more index.php entries in the URL, and sometimes on the end. The following is what I get when I try and go to a JEvents menu item. http://www.myjoomlasite.org/index.php/index.php/index.php/index.php/upcomingevents/month.calendar/2010/06/09/index.php Anyone have any idea why this is happening? I don't know what to search for on Google apparently, and none of the Joomla! books I have address this.

  - by Vipul

  I need to open a new pop up window on click of a button in a view. The new window should be redirect to a specific actionmethod in a specific controller. I also need to provide attributes for size of the new pop up window. I have been trying the following code: <input type="button" name = "ClickMe" Value="ClickMe" onclick= "javascript:window.open('/Home/Create/','Customer Search',height='window.screen.height - 100', width='200',left='window.screen.width - 250' ,top='10',status='no',toobar='no',resizable='yes',scrollbars='yes')"/> On click of button, nothing happens.

I am using Windows Vista with IE 7. I am working on MVC 3 with Razor Engine in VS 2010

• how to find which libraries to link to? or, how can I create *-config (such as sdl-config, llvm-con

  - by numeric

  Hey, I want to write a program that outputs a list of libraries that I should link to given source code (or object) files (for C or C++ programs). In *nix, there are useful tools such as sdl-config and llvm-config. But, I want my program to work on Windows, too. Usage: get-library-names -l /path/to/lib a.cpp b.cpp c.cpp d.obj Then, get-library-names would get a list of function names that are invoked from a.cpp, b.cpp, c.cpp, and d.obj. And, it'll search all library files in /path/to/lib directory and list libraries that are needed to link properly. Is there such tool already written? Is it not trivial to write a such tool? How do you find what libraries you should link to? Thanks.

• In Perl, can I limit the length of a line as I read it in from a file (like fgets)

  - by SB

  I'm trying to write a piece of code that reads a file line by line and stores each line, up to a certain amount of input data. I want to guard against the end-user being evil and putting something like a gig of data on one line in addition to guarding against sucking in an abnormally large file. Doing $str = <FILE> will still read in a whole line, and that could be very long and blow up my memory. fgets lets me do this by letting me specify a number of bytes to read during each call and essentially letting me split one long line into my max length. Is there a similar way to do this in perl? I saw something about sv_gets but am not sure how to use it (though I only did a cursory Google search). Thanks.

• Customers and suppliers database design issue

  - by hectorsq

  I am developing a web application in which I will have customers and suppliers. Initially I thought on using a Customers table and a Suppliers table. Then when I was thinking on bank transactions, I noticed that each transaction needs to refer to a customer or a supplier, so I thought on using a single table named Business in which I will save both customers and suppliers. If I use Customers and Suppliers tables when I want to list the bank transactions I will have to search in both tables to get the company name. If I use a Businesses table I will have to use a business type column, and have the union of possible fields for all businesses types. Any suggestions on the design?

• acts_as_ferret with multiple hosts

  - by Nick

  I've got everything working with ferret and acts_as_ferret for development (or localhost DRb), but I can't get my multiple host deployment working. All of the remote systems get ECONNREFUSED when accessing the port. On the ferret server, the daemon is listening on localhost only despite the configuration listing the FQDN as the host. I also tried switching to a UNIX socket to share data between the ferret DRb daemon and the app code but it too gets ECONNREFUSED. (The socket is available to all of the machines via an NFS mount). Is there a better way to do this or should I be looking for another search indexer? Thanks.

• Timeout not working in SQL Connection

  - by carlos

  I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" If Not t.State = Data.ConnectionState.Open Then t.ConnectionString = constr t.Open() If t.State = Data.ConnectionState.Open Then Return True Else Return False End If Else Return True End If End Using Catch ex As Exception Return False End Try End Function I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored. I search here (Stackoverflow) and internet and found nothing in how to fix this. Any one else have this problem? Or, are there any other ideas on how to let the application know that the DB is ready?

• Android API Target Level 5 and 6 for Ubuntu

  - by Sebi

  Today i installed Ubuntu 10.4 and Eclipse Galileo. Then I downloaded the Android SDK and tried to install all packages via the Android SDK Tools. But unfortunately, only the Target Levels 3, 4, 7 and 8 were available. API Level 5 and 6 are missing. Does anybody know the reason for this? I already did a Google search and there seems to be nobody with the same problem. I also tried to restart it and nothing happens, the API Levels are still missing.

• Whats the difference between a C++ and a Cocoa Project in Xcode?

  - by david

  I need to work with TagLib for my project. I've created a framework (and I tried using it as a lib) but the compiler cannot find #include < strings on compiling (No such file or Directory). I've created a test C++ project and it #includes < strings just fine. I've looked at the project settings and I cannot find a difference between them. But the standard cocoa projects obviously so not have the search path set to include C++ libraries (Or am I completely getting it wrong?). I've searched for a solution but no one else seems to have run into this problem.

• Getting All categories in external page.

  - by Harsha

  This is very basic magento question i guess. I want to first get all the store categories, then loop through them to get their sub-categories and products and similarly continue till the last sub-category. I will be using this in an external page having Mage::app() declared at the top of the page. I am not aware of the Magento API's(if thats wat they are called) to use to get this functionality. Remember I am not using this in any of the templates, so something like getCurrentCategory() will not work here i guess. Also please guide if there are any good resources to search for particular functionality in magento and API's to implement it, or am i doomed to go through their phpdoc to know the list of methods. Any help here will be greatly appreciated, Thanks.

• Which approach to create the data access layer has the highest performance?

  - by pooyakhamooshi

  I have to create a very high performance application. Currently, I am using Entity Framework for my data access layer. My application has to insert some communication data almost every second. I found that Entity Framework is slow; it has about 2 seconds delay to finish the SaveChanges() method. I was thinking I have the following options: 1. Create the data access layer myself using ADO.NET; using stored procedures or ad-hoc queries 2. Use Enterprise Library Data access Layer 3. Use NHibernate 4. Use Repository Factory: http://pooyakhamooshi.blogspot.com/search?q=repository What do you think? which one is quicker for inserting data? Which one is quicker to set up?

• Does the Internet make us less good programmers? [closed]

  - by stagas

  With all the information and code available nowadays on the Internet has that diminished our capability of remembering or learning stuff just because we know they're available somewhere out there, just a Google away or a StackOverflow question away? For example I find myself visiting php.net quite often to check the syntax of the same functions over and over again, not because my memory sucks, but I don't feel like keeping the information in me, since I know I'll find it again on the net. And about StackOverflow, isn't the process of figuring things out on your own supposed to improve your programming skills? If the answers are all just clicks away, do we actually learn something or just keep a pointer in our heads where to search for it again when we need it? Your thoughts are welcome. Hope it doesn't shut down as subjective or anything, the answers would be really interesting ;)

• MySQL SELECT where if stores have X, show me everything that they have

  - by tnt0932

  I have a MYSQL table like this: STORES (SPID, StoreID, ProductID); And data like this: { 1 | s1 | p2 } { 2 | s1 | p7 } { 3 | s1 | p8 } { 4 | s2 | p1 } { 5 | s2 | p3 } { 6 | s2 | p6 } { 7 | s2 | p9 } { 8 | s3 | p2 } { 9 | s3 | p5 } And I would like to: Use a MYSQL SELECT query to get results, where if a store has a certain product, then a list of all of the products at that store will be returned. For example, if I were looking for "p2", then I would like to know that "s1" has "p2, p7, p8" and "s3" has "p2, p5". Please let me know if you require any more information. I'm not sure what is required to solve this issue (Which is probably why I can't search and find the answer!) Thank you.
