  • 'Random' Orderby in webservice using LINQ To Entities

    - by MrDean
    Morning all Now I know there is a reason to this odering but my tiny little brain can't get my head around it. I am using a webservice to pull through data to a webp[age and have the following that is so far pulling data through from UUF1: public string[] GetBuyer(string Memberkey) { try { WebService.EntitiesConnection buyer = new WebService.EntitiesConnection(); return buyer.tblProducts .Where(p => p.MemberId == Memberkey) .OrderBy(p => p.UnitUserfield1) .Select(p => p.UnitUserfield1) .Distinct() .ToArray(); } catch (Exception) { return null; } } This works fine and pulls the data through but in a strange order. Where I would expect results of A B C D E F, it appears to be returning A C E B D F. Could someone point out the error in my ways please?

  • Optimal diff between object lists in Java

    - by Philipp
    I have a List of Java objects on my server which is sent to the client through some serialization mechanism. Once in a while the List of objects gets updated on the server, that is, some objects get added, some get deleted and others just change their place in the List. I want to update the List on the client side as well, but send the least possible data. Especially, I don't want to resend Objects which are already available on the client. Is there a library available which will produce some sort of diff from the two lists, so that I can only send the difference and the new Objects accross the wire? I have found several Java implementation of the unix diff command, but this algorithm is unpractical for order changes. ie. [A,B,C] - [C,B,A] could be sent as only place changes [1-3] [3-1], while diff will want to resend the whole A and C objects (as far as I understand).

  • JavaScript prototype(ing) question

    - by OneNerd
    Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

  • PHP: Iterate through folders and display HTML contends

    - by Mestika
    Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function. Sincere Mestika

  • Normalize database or not? Read only MyISAM table, performance is the main priority (MySQL)

    - by hello
    I'm importing data to a future database that will have one, static MyISAM table (will only be read from). I chose MyISAM because as far as I understand it's faster for my requirements (I'm not very experienced with MySQL / SQL at all). That table will have various columns such as ID, Name, Gender, Phone, Status... and Country, City, Street columns. Now the question is, should I create tables (e.g Country: Country_ID, Country_Name) for the last 3 columns and refer to them in the main table by ID (normalize...[?]), or just store them as VARCHAR in the main table (having duplicates, obviously)? My primary concern is speed - since the table won't be written into, data integrity is not a priority. The only actions will be selecting a specific row or searching for rows that much a certain criteria. Would searching by the Country, City and/or Street columns (and possibly other columns in the same search) be faster if I simply use VARCHAR?

  • Javascript opens new window despite no call

    - by Jimmy
    I have a javascript that opens a new window for "PreChecking" a site. The problem is when i click the button, it works fine... but wichever i button i press next makes the method fire again, despite i doesn't call it. Its just the button with id "lnkPrecheck" that should call the method. Have searched far and wide for a slolution that just opens a new window for the lnkPrecheck button, not the others on the site. THere must be a way for only 1 of 3 buttons makes the function call, not all of them! The code: <asp:Button OnClick="lnkPrecheck_Click" OnClientClick="NewWindow();" ID="lnkPrecheck" runat="server" text="Precheck (Opens in a new window)" /> function NewWindow() { document.forms[0].target = "_blank"; }

  • is there an equivalent to a "Focus Listener" in Objective-C or iPhone SDK? (Coming from Java)

    - by MarcZero
    Hello. I am a student programmer who has taken up Objective-C on my free time as my college doesn't teach it. We have only used Java and basic C so far. I am in the middle of making a program for the iPod and was wondering if there was any type of way to call a method in a class similar to the way a Focus Listener does in Java? I have a view that I would like to call a refresh method (to update the newly inputted titles of buttons from another view) when the view is put at the top and visible again. Is this too easy or is there a more methodical way of doing that? I have tried to just call the method from the other view class but it does not seem to work (says the other class is either undefined or may not accept the method call and crashes on execution). Any insight would be appreciated. Thank you for your time.

  • How do stop form posting to mysql if database contains a specific ID?

    - by user342391
    I have a form that I am using to post data to mysql. Before submitting the form I want to check the database and see if there are any fields in the column 'customerid' that equal 'userid' and if so not to post the form. Basically, I am trying to limit my users from posting more than once. Users will be able to login to my system and make ONE post. They will be able to delete and modify their post but are only limited to one post. How would I do this??? Code so far: <?php include '../login/dbc.php'; page_protect(); $userid = $_SESSION['user_id']; $sql="INSERT INTO content (customerid, weburl, title, description) VALUES ('$_POST[userid]','$_POST[webaddress]','$_POST[pagetitle]','$_POST[pagedescription]')"; if (!mysql_query($sql)) { die('Error: ' . mysql_error()); } echo "1 record added"; ?>

  • How is this problem usually solved without using sever-side scripting?

    - by cyggi
    Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

  • Javascript, jQuery - how signed actions to just created object?

    - by sebap123
    I am trying to make simple list with ability to add and delete elements. For now I am working on adding and performing a simple action on each of list elements object (existing and added). Unfortunately I have met some difficulties with that. I am able to modify objects that are created at the beginning, but not one added during "webpage working". First of all my idea was to add AJAX to this, but I don't think it is the easiest way. I think that some time ago (I don't remember where) I read how to make this work, but now I don't know. I would be really glad if someone would help me with this or at least give a link to good explanation of this. There is what I have done so far (well this is mostly just a scratch, but the main idea is in it): http://jsfiddle.net/sebap123/pAZ7H/ Thank you for all responses.

  • C# - opening process and changing window position

    - by bartq
    I want to open from c# an application (standalone flashplayer) and set it position to (0,0) on the screen. How can I do this? So far I've managed to open flashplayer: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace swflauncher { class Program { static void Main(string[] args) { Process flash = new Process(); flash.StartInfo.WindowStyle = ProcessWindowStyle.Normal; flash.StartInfo.FileName = "D:\\development\\flex4\\runtimes\\player\\10\\win\\FlashPlayer.exe"; flash.Start(); } } }

  • How to arrange labels in a flowlayout manner?

    - by Tim Büthe
    How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

  • How to add up amount of data from an external file in C# (Stream Reader)

    - by user2985995
    I'm new to this site, and pretty new to programming, at the moment I'm trying to display a count amount for the users names on my donation list, and then I also want to have a sum to work out the total amount of money the donation list contains, If someone could help me with creating a way to add up amount of donors on the donations.txt file that would be great help, I have no idea where to start, but so far this is my coding: string sName; double dAmount; string sTotalNames; double dAmountTotal; double dAmountAverage; using (StreamReader sr = new StreamReader("Donations.txt")) { while (sr.Peek() != -1) { sName = sr.ReadLine(); Console.WriteLine(sName); dAmount = Convert.ToDouble(sr.ReadLine()); Console.WriteLine(dAmount); } Console.WriteLine("Press any key to close"); Console.ReadKey(); }

  • Why does the compiler complain "while expected" when I try to add more code?

    - by user1893578
    Write a program with a word containing @ character as an input. If the word doesn't contain @, it should prompt the user for a word with @. Once a word with @ is read, it should output the word then terminate. This is what I have done so far: public class find { public static void main(String[] args) { System.out.println(" Please enter a word with @ "); Scanner scan = new Scanner(System.in); String bad = "@"; String word = scan.next(); do if (!word.contains(bad)) System.out.println(" Please try again "); else System.out.println(" " + word); while (!word.contains(bad)); } } I can get it to terminate after a word containing "@" is given as input, but if I try to add a Scanner to the line after "please try again", it says while expected.

  • Android Java Eclipse Intent with 2 Projects

    - by user3793685
    Good day! I have 2 Projects in my Eclipse. MainActivity1 and MainActivity2 are the names of the activities. The MainActivity2 is connected to the MainActivity1 via Project in the properties of the MainActivity1. So far, I can call the package of the MainActivity2 from the MainActivity1. Now, below are my problem: I have a button in MainActivity1. What I want to do is after I click on the button in the MainActivity1, it runs the MainActivity2 project and some variables will be passed on to the MainActivity2. I've been searching in google for a while now and I couldn't get the right keyword for it. I've checked some of the questions here in StackOverflow but I'm unable to locate the problem similar to mine with calling and running the MainActivity2 class from the MainActivity1.java I'm a noob in Android Java but have knowledge in other OOP. Any tips will be a great help. Thanks

  • Is there any difference in the implementation of these three validation methods?

    - by dontWatchMyProfile
    Core Data is calling these methods in certain situations: - (BOOL)validateForInsert:(NSError **)outError; - (BOOL)validateForUpdate:(NSError **)outError; - (BOOL)validateForDelete:(NSError **)outError; I wonder if they're doing anything different, or if they're essentially doing the exact same things. As far as I know, these methods call the -validateValue:forKey:error: method once for every property. The only difference I can imagine is in the .validateForDelete: method. I see no reason why to validate an object when it shall be deleted, except for applying delete rules, probably only in the case of the DENY rule.

  • iphone UIPicker question

    - by Rob
    I have a picker that prompts the user to choose a gender and an age group (17-21, 22-26, etc.) These 2 choices determine which view the user will be brought to after pressing the button, but I am having troubles writing the method for that button. The code I have so far is this: - (IBAction) buttonPressed { NSInteger genderRow = [genderPicker selectedRowInComponent:0]; NSString *genderSelected = [genderPickerData objectAtIndex:genderRow]; NSInteger ageRow = [agePicker selectedRowInComponent:1]; NSString *ageSelected = [agePickerData objectAtIndex:ageRow]; if (genderSelected == "Male" && ageSelected == "17-21") { Calc2ViewController *calc2ViewController = [[Calc2ViewController alloc] initWithNibName:@"Calc2View" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:calc2ViewController animated:YES]; [calc2ViewController release]; calc2ViewController = nil; } } When I run the program, and select these 2 groups (Male and 17-21) - nothing happens. What am I missing?

  • XCode 3.2.5 Cocoa project modifies linked 3rd party dylib. Why?

    - by Barrie
    I'm linking a 3rd party dylib into a cocoa project. And I arrange for XCode to copy it into the Frameworks directory of the app. But when I cmp the original dylib with the dylib in Frameworks I discover the 3rd party dylib has been modified. I have some old XCode cocoa projects which don't do this, i.e. the dylib in Frameworks is the same as the original. I've tried modifying the XCode projects to isolate what is causing the dylib to be modified but so far no luck. Any ideas?

  • Creating a file path in C#

    - by Jason
    So I'm trying to create a path in C#. I use Environment.Machinename and store it a variable serverName. Then I create another string variable and have some other path extension in there. Here is my code so far: string serverName = Environment.MachineName; string folderName = "\\AlarmLogger"; No matter what I do I can't seem to obtain only one backslash prior to AlarmLogger. Any ideas how I can specify a path in C#? Edit: I'm wondering if my code doesn't seem to want to paste correctly. Anyways when i paste it I only see one backslash but my code has two. Because of the escape character sequence. But something like string test = @"\" + serverName + folderName doesn't seem to want to work for me.

  • Long to timestamp for historic data (pre-1900s)

    - by Mike
    I have a database of start and stop times that have previously all had fairly recent data (1960s through present day) which i've been able to store as long integers. This is very simialr to unix timestamps, only with millisecond precision, so a function like java.util.Date.getTime() would be the value of the current time. This has worked well so far, but we recently got data from the 1860s, and the following code no longer works: to_timestamp('1-JAN-1970 00:00:00', 'dd-mon-yyyy hh24:mi:ss') + numtodsinterval(int_to_convert/(1000),'SECOND' ); This wraps the date and we get timestamps in the year 2038. Is there a way around this issue? All of the documentation i've looked at the documentation and timestamps should be able to handle years all the way back to the -4000 (BC), so i'm suspecting an issue with the numtodsinterval. Any ideas suggestions would be greatly appreciated.

  • Best way to test class methods without running __init__

    - by KenFar
    I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little.

  • Taking a break from programming harmful to career?

    - by Chris
    I'm currently taking a year out from University to do an internship at a large (well known) software vendor. I'll be returning to Uni next September for a year to finish my studies. I really want to take a year out after graduation, I won't be doing any programming in this year. Will this make me less competitive when applying for programmer jobs when I get back from my year away? I'm looking to work with the Microsoft technology stack, my internship has been all Java and Unix thus far. The assumption is I won't be taking up a full time offer with the company I interned at (despite the offer).

  • As a Web Developer, how complicated is your average job compared to this?

    - by Daniel S
    I'm 16 years old, and I've recently started to do freelance jobs. I've been playing with PHP since I was 12 and think that I can code reasonably well. So far, I've created a library for fetching info from LinkedIn profiles and some WordPress plugins. However, right now this client wants me to convert an HTML template into a WordPress theme for use as a website. I feel this is a tad easy. As professional web programmers, are most assignments harder than this?

  • PHP Detect Pages Genre/Category

    - by Alexwhin
    Hey, I was wondering if their was any sort of way to detect a pages genre/category. Possibly their is a way to find keywords or something? Unfortunately I don't have any idea so far, so I don't have any code to show you. But if anybody has any ideas at all, let me know. Thanks! EDIT @Nican Perhaps their is a way to set, let's say 10 category's (Entertainment, Funny, Tech). Then creating keywords for these category's (Funny = Laughter, Funny, Joke etc). Then searching through a webpage (maybe using a cUrl) for these keywords and assigning it to the right category. Hope that makes sense.
