  • Rookie PHP question

    - by Thomas
    I am hacking together a theme for wordpress and I am using the following code to pull out data from a custom field with several values: <?php $mykey_values = get_post_custom_values('services'); foreach ( $mykey_values as $key => $value ) { echo "<span>$value, </span>"; } ?> I use a comma to seperate the results, but I don't want a comma after the last result. How do I get around this?

  • Asp.net Login Status Question: It Aint Working

    - by contactmatt
    I'm starting to use Role Management in my website, and I'm current following along on the tutorial from http://www.asp.net/Learn/Security/tutorial-02-vb.aspx . I'm having a problem with the asp:LoginStatus control. It is not telling me that I am currently logged in after a successful login. This can't be true because after successfully logging in, my LoggedInTemplate is shown. The username and passwords are simply stored in a array. Heres the Login.aspx page code. Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles btnLogin.Click ' Three valid username/password pairs: Scott/password, Jisun/password, and Sam/password. Dim users() As String = {"Scott", "Jisun", "Sam"} Dim passwords() As String = {"password", "password", "password"} For i As Integer = 0 To users.Length - 1 Dim validUsername As Boolean = (String.Compare(txtUserName.Text, users(i), True) = 0) Dim validPassword As Boolean = (String.Compare(txtPassword.Text, passwords(i), False) = 0) If validUsername AndAlso validPassword Then FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, chkRemember.Checked) End If Next ' If we reach here, the user's credentials were invalid lblInvalid.Visible = True End Sub Here is the content place holder on the master page specifically designed to hold Login Information. On successfull login, the page is redirected to '/Default.aspx', and the LoggedIn Template below is shown...but the status says Log In. <asp:ContentPlaceHolder Id="LoginContent" runat="server"> <asp:LoginView ID="LoginView1" runat="server"> <LoggedInTemplate> Welcome back, <asp:LoginName ID="LoginName1" runat="server" />. </LoggedInTemplate> <AnonymousTemplate> Hello, stranger. </AnonymousTemplate> </asp:LoginView> <br /> <asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect" LogoutPageUrl="~/Logout.aspx" /> </asp:ContentPlaceHolder> Forms authentication is enabled. I'm not sure what to do about this :o.

  • question about Doug Lea's malloc

    - by hatorade
    http://gee.cs.oswego.edu/dl/html/malloc.html in making his array for the segmented bins, he makes bins for 8 - 512 using multiples of 8 (so 63 bins, but only the last 62 are ever used). how does he determine the size for the remaining 63 bins? He mentions they are logarithmically spaced, but is there some sort of equation he used to do that optimally?

  • a question on common lisp

    - by kostas
    Hello people, I'm getting crazy with a small problem here, I keep getting an error and I cant seem to figure out why, the code is supposed to change the range of a list, so if we give it a list with values (1 2 3 4) and we want to change the range in 11 to fourteen the result would be (11 12 13 14) the problem is that the last function called scale-list will give back an error saying: Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) anybody has a clue why? I use aquamacs as an editor thanks in advance ;;finds minimum in a list (defun minimum(list) (car (sort list #'<))) ;;finds maximum in a list (defun maximum(list) (car (sort list #'>))) ;;calculates the range of a list (defun range(list) (- (maximum list) (minimum list))) ;;this codes scales a value from a list (defun scale-value(list low high n) (+ (/ (* (- (nth (- n 1) list) (minimum list)) (- high low)) (range list)) low)) ;and this code is supposed to scale the whole list (defun scale-list(list low high n) (unless (= n 0) (cons (scale-value list low high n) (scale-list list low high (- n 1))))) (scale-list '(0.1 0.3 0.5 0.9) 20 30 4)

  • PHP array : simple question about multidimensional array

    - by Tristan
    Hello, i've got a SQL query which returns multiple rows, and i have : $data = array( "nom" => $row['nom'] , "prix" => $row['rapport'], "average" => "$moyenne_ge" ); which is perfect, but only if my query returns one row. i tried that : $data = array(); $data[$row['nom']]["nom"] = $row['nom'] ; ... $data[$row['nom']]['average'] = "$moyenne_ge"; in order to have : $data[brand1][nom] = brand1 $data[brand1][average] = 150$ $data[brand2][nom] = brand2 $data[brand2][average] = 20$ ... but when i do : json_encode($data) i only have the latest JSON object instead of all JSON object from my request as if my array has only one brand instead of 10. I guess i did something stupid somewhere. Thanks for your help

  • need thoughts on my interview question - .net, c#

    - by uno
    One of the questions I was asked was that I have a database table with following columns pid - unique identifier orderid - varchar(20) documentid - int documentpath - varchar(250) currentLocation - varchar(250) newlocation - varchar(250) status - varchar(15) I have to write a c# app to move the files from currentlocation to newlocation and update status column as either 'SUCCESS' or 'FAILURE'. This was my answer Create a List of all the records using linq Create a command object which would be perform moving files using foreach, invoke a delegate to move the files - use endinvoke to capture any exception and update the db accordingly I was told that command pattern and delegate did not fit the bill here - i was aksed to think and implement a more favorable GoF pattern. Not sure what they were looking for - In this day and age, do candidates keep a lot of info on head as one always has google to find any answer and come up with solution.

  • Question about WinForms TrackBar control in .Net

    - by Jules
    Does anyone know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse? I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects. I've had a look in reflector but it's one of those controls where most of the implementation is not viewable. ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this? Thanks

  • Very dumb question about IntelliJ IDEA

    - by Alex R
    I'm a long-time Eclipse user and I just now decided to try IntelliJ IDEA 9 (free edition) for Scala. A couple of dumb questions: How can I tell if a file I've modified has been saved? How can I tell if I file I've saved has been checked into CVS? I feel incredibly "exposed" to some sort of imminent danger when I don't see the familiar visual cues from Eclipse that indicate a file has been saved and/or checked in. Thanks

  • Databinding question: DataGridView <=> XDocument (using LINQ-to-XML)

    - by Pretzel
    Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

  • Objective-C assigning variables question for iphone.

    - by coder net
    The following piece of code can be written in two ways. I would like to know what are the pros and cons of each. If possible I would like to stick with the one liner. 1) UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"Background.png"]]; self.view.backgroundColor = background; [background release]; 2) self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"Background.png"]]; Any issues with releasing memory etc. with #2? I'm new to Objective-C and would like to follow the best approach.

  • HTML/CSS layout question

    - by TheDelChop
    Guys, I just need a little help with some CSS layout if you don't mind. I've got three things I'm trying to play around with and I need some help making this work the way I was hoping. I've got the element of a page, which I'd like to be 100% of the browser window, obviously. Then I've got two elements which I'd like to stack on top of each other, but the trick is this, I'd like the bottom div, (a menu which should really be a fixed height) to determine the height of the top div. Is there a way to lay this out in CSS?

  • WPF Binding Question - Change Label Text based on Modifier Key Control

    - by Chuck Savage
    I have a context menu, that I'd like to change the Header based on whether the Control Key is pressed or not. Right now I have, <MenuItem Header="Send To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> I'd like based on the Control Key being down to be, <MenuItem Header="Move To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> All I really need to do is change the Header text, because inside the code I know how to check for the Modifier key being Control.

  • Question about functional OOP style in JavaScript

    - by valums
    I prefer to use functional OOP style for my code (similar to the module pattern) because it helps me to avoid the "new" keyword and all problems with the scope of "this" keyword in callbacks. But I've run into a few minor issues with it. I would like to use the following code to create a class. namespace.myClass = function(){ var self = {}, somePrivateVar1; // initialization code that would call // private or public methods privateMethod(); self.publicMethod(); // sorry, error here function privateMethod(){} self.publicMethod = function(){}; return self; } The problem is that I can't call public methods from my initialization code, as these functions are not defined yet. The obvious solution would be to create an init method, and call it before "return self" line. But maybe you know a more elegant solution? Also, how do you usually handle inheritance with this pattern? I use the following code, butI would like to hear your ideas and suggestions. namespace.myClass2 = function(){ var self = namespace.parentClass(), somePrivateVar1; var superMethod = self.someMethod; self.someMethod = function(){ // example shows how to overwrite parent methods superMethod(); }; return self; } Edit. For those who asked what are the reasons for choosing this style of OOP, you can look into following questions: http://stackoverflow.com/questions/1557386/prototypal-vs-functional-oop-in-javascript http://stackoverflow.com/questions/383402/is-javascript-s-new-keyword-considered-harmful

  • General N-Tier Architecture Question

    - by whatispunk
    In an N-Tier app you're supposed to have a business logic layer and a data access layer. Is it bad to simply have two assemblies: BusinessLogicLayer.dll and DataAccessLayer.dll to handle all this logic? How do you actually represent these layers. It seems silly, the way I've seen it, to have a BusinessLogic class library containing classes like: CustomerBusinessLogic.cs, OrderBusinessLogic.cs, etc. each calling their appropriately named cousin in the DataAccessLayer class library, i.e. CustomerDataAccess.cs, OrderDataAccess.cs. I want to create a web app using MVP and it doesn't seem so cut and dry as this. There are lots of opinions about where the business logic is supposed to be put in MVP and I'm not sure I've found a really great answer yet. I want this project to be easily testable, and I am trying to adhere to TDD methodologies as best I can. I intend to use MSTest and Rhino Mocks for testing. I was thinking of something like the following for my architecture: I'd use LINQ-To-SQL to talk to the database. WCF services to define data contract interfaces for the business logic layer. Then use MVP with ASP.NET Forms for the UI/BLL. Now, this isn't the start of this project, most of the LINQ stuff is already done, so its stuck. The WCF service would replace the existing DataAccessLayer assembly and the UI/BLL would replace the BusinessLogicLayer assembly etc. This sort of makes sense in my head, but its getting really late. Anyone that's traveled down this path have any guidance? Good links? Warnings? Thanks!
