• Returning unique values of a multi-dimensional array with CodeIgniter PHP

  - by Michael Bradley

  Hi - I'm developing a property rentals website. The search results page will contain a list of property results. It is my intention to redefine the results, say by town, country, property type etc. So let's say for example the user searches 'France'. All of the relative properties will be returned and displayed in a list. However, I also need to reuse this array, to display only unique town names from the search results array. e.g. Montpellier, Lyon, Rennes, Nice etc. The idea is when use user click on 'Nice', only the 'Nice' properties would return. I would also like to display how many properties are in that town. The closest example as to what I want to achieve. http://www.miaandmaggie.com/dog-collars-leashes.html Any ideas how I can use my search array to display the unique towns of the search? Many thanks!

• PHP variable passed to JasperServer for reports

  - by Ronedog

  Is it possible to pass a variable from php to a report in JasperServer? For example, in my php application I keep the department_id stored in a session variable. I would like to pass the department_id over to my reports running on JasperServer and display the information appropriate for that department. in the iReport I have a query like: "SELECT * FROM employees WHERE department_id = $P{dept_id_from_php}", but I have to build a dropdown select list to pass the dept_id parameter. The end result is I would like the user logged into my PHP application to view the employee information that is related to the department the logged-in-user belongs to. I don't want to pass this over using the querystring because the user could just change the id in the querystring and have access to other departments information. Ideally I would like to only pass that parameter once, then reuse it in all the reports, like a global variable. Is this possible?

• Custom drop down

  - by Rob

  I'm trying to create a custom drop down and using the code below it works pretty well - only one problem is if i have more than one drop down, all the links will only activate the first drop down. Any ideas on how I would fix that? (and yes I know about Suckerfish I just need to get this to work) function toggle() { var ele = document.getElementById("dropdown-items"); var text = document.getElementById("dropdown-menu"); if(ele.style.display == "block") { ele.style.display = "none"; } else { ele.style.display = "block"; } }

• How do you get notified of your repos' updates?

  - by furtelwart

  I'm working on several repositories at work and would like to be informed, if anything changes in the SVN repositories. I made a small BAT script (yes, BAT is usefull sometimes) that keeps executing an svn log -r BASE:HEAD on my working copy. It shows all submit comments and revision dates. It works really well but it's not comfortable for different repositories. How do you keep track of changes in your repositories? Do you use a small program you made for yourself? Do you use software someone else made? I'm interested in every approach to this problem. I would like to get notifications and several more information about the commit. The IDE integrated functions are good, but work only if I request the information. I don't want to act to get this information. Platform: Windows, Subversion 1.5 and higher.

• php / mysql pagination

  - by arrgggg

  Hi, I have a table with 58 records in mysql database. I was able to connect to my database and retrive all records and made 5 pages with links to view each pages using php script. webpage will look like this: name number john 1232343456 tony 9878768544 jack 3454562345 joe 1232343456 jane 2343454567 andy 2344560987 marcy 9873459876 sean 8374623534 mark 9898787675 nancy 8374650493 1 2 3 4 5 that's the first page of 58 records and those 5 numbers at bottom are links to each page that will display next 10 records. I got all that. but what I want to do is display the links in this way: 1-10 11-20 21-30 31-40 41-50 51-58 note: since i have 58 records, last link will display upto 58, instead of 60. Since I used the loop to create this link, depending on how many records i have, the link will change according to the number of records in my table. How can i do this? Thanks.

• Code editor with autocomplete

  - by Andrey

  I need to create a code editor for my own simple language: className.MethodName(parameterName = 2, ... ) I've created the appropriate grammar and autogenerate parser using ANTLR tool. Now I would like to have an autocomplete for class, method, variables and parameter names. This list should be context dependent, f.e. for "class." it should display methods and for "class.Method(" - parameters. I was going to parse the text and display the list depending on in which node the cursor is. The problem is that for incomplete code like "aaa.bbb(" the parser produces an error instead of a syntax tree. Any idea how to solve this problem? Maybe I'm on the wrong way and I shouldn't parse code to display autocomplete?

• How does Bitmap.Save(Stream, ImageFormat) format the data?

  - by Matt Jacobsen

  I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

• Python: writing a program to compute the area of a circle and square

  - by user1672504

  I have a question with an assignment. I'm not sure how to write this program and I really need help! Could someone help me with this? This is the assignment: Write a program that asks the user to enter two values: an integer choice and a real number x. If choice is 1, compute and display the area of a circle of radius x. If choice is 2, compute and display the are of a square with sides of length x. If choice is neither 1, nor 2, will display the text Invalid choice. Sample run: Enter choice: 2 Enter x: 8 The area is: 64.0 Sample run: Enter choice: 1 Enter x: 8 The area is: 201.06176 My attempt: choice = input ('Enter Choice:') choice_1 = int (choice) if (choice_1==1): radius = (int) print('Enter x:',radius) pi = 3.14159 area = ( radius ** 2 ) * pi print ( 'The Area is=' , area )

• Markers in Google Maps Application

  - by Samuh

  I am supposed to display a certain location using Google Maps application. I have lat/long values and tried Intent.ACTION_VIEW with "geo:lat,long?z=15" uri. The Google Maps application loads centered on the supplied lat-long value but obviously does not display any marker(overlays) pin-pointing the location. Is it possible to request the Google Maps App to display markers? Also, the zoom level paramater doesnt seem to work. Maps load at the default zoom level of 10. I can easily achieve this using MapActivity but Google Map App is what is desired. Thanks

• How to rebase onto a private branch with conflicts in gerrit/git?

  - by edwardmlyte

  Aim: I want to rebase commit G from "bravo", onto commit F from "alpha". From this: G bravo / D--E--F alpha / A--B--C mainline To this: G bravo / D--E--F alpha / A--B--C mainline "alpha" has been successfully rebased onto the latest mainline work. I cherry-pick "alpha" onto C. And when I cherry-pick "bravo", it comes up with all the merge conflicts. Once I fix those, if I do commit --amend The commit message just has all the information for alpha, whereas I'd expect the information for bravo. So I tried again after hard resetting to C, doing pull (as oppose to cherry-pick) for alpha and then pull bravo. Fixed the conflicts and just ran: commit The commit message just lists it as a merge and has merge information. Though the commit succeeds, I can't push this to gerrit as it says I don't have the rights to push merges. When I've read about rebase, it's always just to mainline, but I want to rebase private branches. Where am I going wrong?

• What would you like to see in an beginner's ASP.NET security book

  - by blowdart

  This is a shameless information gathering exercise for my own book. One of the talks I give in the community is an introduction to web site vulnerabilities. Usually during the talk I can see at least two members of the audience go very pale; and this is basic stuff, Cross Site Scripting, SQL Injection, Information Leakage, Cross Site Form Requests and so on. So, if you can think back to being one, as a beginning web developer (be it ASP.NET or not) what do you feel would be useful information about web security and how to develop securely? I will already be covering the OWASP Top Ten (And yes this means stackoverflow will be in the acknowledgements list if someone comes up with something I haven't thought of yet!) It's all done now, and published, thank you all for your responses

• TypeConverter.ConvertFrom String to String

  - by Ken

  I'm using a PropertyGrid to display a property. For one property, I'm displaying strings in a drop-down combobox. The displayed text of the property and the value of the property are both strings, but their text is different. The displayed text is friendly, the value text corresponds to a registry key name. I've created a TypeConverter to convert between the display text and the value text, but the ConvertFrom() method appears to work correctly until I change the combo-box selection. It then sends the 'value' text instead of the display text to use during the conversion. Has anyone else used string-to-string conversion successfully?

• Extending configuration for .Net 3.5 Applications

  - by Maximiliano Rios

  Due to a requirement in my current project, I have to build a configuration manager to handle configurations that merge local config info with database one. Custom configuration doesn't fit my needs, problem is that I don't know what's the type before loading certain information, for example: Loading database information I will able to know what's myhandler's type. Not previously. So I thought to write my own handler but I can't let set blank as type for sections, in fact .net requires to know what's the type to match myhandler nodes. I'm thinking on building a different parser to read XML nodes but I would prefer to match this structure. I've not found any information to do that yet, is there any way? Can I extend or hook up something into the framework to be capable of loading on-the-fly types and validate nodes? Thanks in advance.

Everything seems to work except the code I put in italic.

• LINQ DataLoadOptions - Retrieval of data via Fulltext/Broken Foreign Key Relationship

  - by Alex

  I've hit a brick wall: I have an SQL Function: FUNCTION [dbo].[ContactsFTS] (@searchtext nvarchar(4000)) RETURNS TABLE AS RETURN SELECT * FROM Contacts INNER JOIN CONTAINSTABLE(Contacts, *, @searchtext) AS KEY_TBL ON Contacts.Id = KEY_TBL.[KEY] which I am calling via LINQ public IQueryable<ContactsFTSResult> SearchByFullText(String searchText) { return db.ContactsFTS(searchText); } I am projecting the ContactsFTSResult collection into a List<Contact> which is then given to my viewmodel. Here is the problem: My Contacts table (and therefore the Contact object created via LINQ to SQL) has multiple FK relationships to other information, such as Contact.BillingAddressId is an FK to an Address.Id. That information is missing after I do the fulltext search (e.g. if I try to access Contact.BillingAddress it is null). Can I add this information somehow via DataLoadOptions? I tried LoadWith<Contact>(c => c.BillingAddress) but this doesn't work, I assume because of the fact that I'm calling the function instead of doing the whole query via LINQ.

• Change input text to regular text on blur and ability to edit jQuery

  - by eknown

  I'm creating a form where I'm eliminating the use of a save button. The form is made up of input text boxes and textareas. After the user enters data into the input field, I want to trigger an onBlur function and change the input into a span that contains the information that the user entered. I also want to have the ability to edit this information, so if the user clicks on the newly created span with text, it will turn back into the input field with the current information for their editing pleasure. For reference, I'm looking to have a functionality pretty much like on editing a photo title on Flickr. If possible, I'd also like to have the textbox show "saving..." for half a second after the blur to reflect interaction with server.

• Crystal Reports Legends

  - by AWinters

  Is there a way to force a Bar Chart legend in Crystal Report 11.5 to display its objects in a particular order? For Example, say I am reporting on the consumption of "Bananas" and "Apples" by State. The Bar Chart should display the percentage of people who eat these fruits by county (Percent Bar Chart). The "Apples" percentage always displays on top of the bar chart and the "Bananas" on the bottom. The legend for this graph also displays the "Apple" color first, then the "Banana" color. However, if the "Banana" percentage is 0% the legend displays the "Banana" color first on the legend. This creates a inconsistent report (with plenty of complaints). I would like the "Banana" color to always display second in the legend. Hope I didn't confuse anyone and any ideas would be helpful.

• How to structure class to support imported 3d model ?

  - by brainydexter

  Hello, I've written a C++ library that reads in this 3d model file (collada DAE). uptil now, I would output a list of triangles and handle each at rendering stage. But now, I need to attach some Bounding sphere information with the imported model. I need some advice on how should I organize this in code. Here are some specs of the 3D file format: - 3D model is represented as a Tree consisting of nodes - each node can contain other nodes, geometry information, transformation etc My requirements: - a bounding sphere associated with each node, thereby yielding a tree of bounding sphere hierarchy for the model itself. - actual vertex information What would be the recommended way to deal with this situation? Thanks
