  • How do I set font size to 0px in IE6?

    - by Justin808
    I have an unordered list, I'm trying to hide the text in the list. I can do this 2 ways that i know of: font-color: transparent; font-size: 0px; I prefer the 0px method as its not selectable. This issue is neither way works in IE6. The first way just doesn't work in IE6 at all, the 2nd leave a 1PX high font. Is there a way to hide the text in IE6? This is a visual thing, I know you can read the text by reading the source and that is OK, I just need it to visually not be there.

  • How to set custom form input field for "Price"?

    - by RodeoRamsey
    I have a basic html form that adds some data to the page using PHP. I want to make this form field a "Price" field. My html is: <input class="bids" name="comment" id="comment" tabindex="4" /> How can I fix this field so that users can't enter random letters, dollar signs, dashes, or other weird formats. I want the output to be whole dollars. Sorry I'm a complete programming moron. :)

  • What does the length attribute do when set on the @Column JPA annontation?

    - by James McMahon
    What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

At the moment I am having to place the file with the correct name in the project folder, build, then swap it out with a different one and build the other target. Is there an easier way? Thanks

  • why can't I set a new instance's delegate as self?

    - by Guille10k
    I have a uipickerview, which appears with an ActionSheet. All this is in a class "MultiPicker". I create a new instance from "FirstViewController" this way: multiPicker *multiPic = [[multiPicker alloc]init]; multiPic.delegate = self; [multiPic action:aRunIndex]; And inside "multiPicker", in "action:" UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:title delegate:otroDelegate cancelButtonTitle:nil destructiveButtonTitle:@"Cancel" otherButtonTitles:@"Done", nil]; UIPickerView *pickerView = [[[UIPickerView alloc] init] autorelease]; pickerView.tag = 101; pickerView.delegate = self; pickerView.dataSource = self; pickerView.showsSelectionIndicator = YES; [actionSheet addSubview:pickerView]; [actionSheet showInView:self.view]; I need "FirstViewController" when MultiPicker finishes, so I can update a table in FirstView. I tried setting a new delegate to MultiPicker so, it tells FirstView when it finishes. But the instruction "multipic.delegate = self" in the first piece of code mades the app crash and says "Terminating due to uncaught exception". If I simply put all "MultiPicker" code inside FirstViewController class, not in a separate one, the action sheet stay blocked when I try to push a button different from "Cancel" Any idea? Thank u

  • How is a set partitioned into valid and invalid items using LINQ?

    - by Aaron Anodide
    Is there a way to write a single LINQ expression to get the same result of the following code? var validations = new Func<conversion, bool>[] { c => c.affiliate.affiliate_id > 0, c => c.campaign_id > 0 }; var invalidConversions = from c in extractedConversions where validations.Any(valid => !valid(c)) select c; var validConversions = from c in extractedConversions where validations.All(valid => valid(c)) select c;

  • How to set Camera View as background with views over it?

    - by Android Student
    So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

  • Add a List<object> to EF

    - by Billdr
    I'm playing around with EF, trying to get my bearings. Right now I'm writing a blackjack game for a website. The problem is that my whenever I pull a GameState from the database, the playerHand, dealerHand, theDeck, and dealerHidden properties are null. public class GameState { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int gameSession { get; set; } public int playerScore { get; set; } public int dealerScore { get; set; } public Deck theDeck { get; set; } public List<Cards> playerHand { get; set; } public List<Cards> dealerHand { get; set; } public Cards dealerHidden { get; set; } public bool gameOver { get; set; } } public class Cards { [Key] [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int cardId { get; set; } public string cardName { get; set; } public int cardValue { get; set; } } public class GameStateContext : DbContext { public GameStateContext() : base("MyContext") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Entity<GameState>().HasRequired(e => e.theDeck); modelBuilder.Entity<GameState>().HasRequired(e => e.dealerHand).WithMany().WillCascadeOnDelete(false); modelBuilder.Entity<GameState>().HasRequired(e => e.playerHand).WithMany().WillCascadeOnDelete(false); modelBuilder.Entity<GameState>().HasOptional(e => e.dealerHidden); modelBuilder.Entity<Deck>().HasRequired(e => e.cards).WithMany().WillCascadeOnDelete(false); base.OnModelCreating(modelBuilder); } public DbSet<GameState> GameStates { get; set; } public DbSet<Deck> Decks { get; set; } public DbSet<Card> Cards { get; set; } } The cards and deck table are populated. Where am I going wrong?

  • Prolog Beginner: How to unify with arithmentic cmparison operators or how to get a set var to range

    - by sixtyfootersdude
    I am new to prolog. I need to write an integer adder that will add numbers between 0-9 to other numbers 0-9 and produce a solution 0-18. This is what I want to do: add(in1, in2, out) :- in1 < 10, in2 < 10, out < 18. I would like to be able to call it like this: To Check if it is a valid addition: ?- add(1,2,3). true ?- add(1,2,4). false With one missing variable: ?- add(X,2,3). 1 ?- add(1,4,X). 5 With multiple missing variables: ?-add(X,Y,Z). % Some output that would make sense. Some examples could be: X=1, Y=1, Z=2 ; X=2, Y=1, Z=3 ...... I realize that this is probably a pretty simplistic question and it is probably very straightforward. However cording to the prolog tutorial I am using: "Unlike unification Arithmetic Comparison Operators operators cannot be used to give values to a variable. The can only be evaluated when every term on each side have been instantiated."

  • How do I set bash environment variables from a script?

    - by James A. Rosen
    I have some proxy settings that I only occasionally want to turn on, so I don't want to put them in my ~/.bash_profile. I tried putting them directly in ~/bin/set_proxy_env.sh, adding ~/bin to my PATH, and chmod +xing the script but though the script runs, the variables don't stick in my shell. Does anyone know how to get them to stick around for the rest of the shell session?
