  • Why might my Emacs use spaces instead of tabs?

    - by Fletcher Moore
    I am trying to diagnose this problem. TAB creates 4 spaces instead of a 4 col TAB like I want. But I don't think it should because C-h v indent-tabs-mode on the buffer in question says it is set to t. When I check my keybindings, TAB is set to c-indent-line-or-region. Does this function ignore my tabs-mode?

  • Adding file names to an array list in java

    - by Chris G
    Hi I am currently needing to load the contents of a folders filenames to an arraylist I have but I am unsure as how to do this. To put it into perspective I have a folder with One.txt, Two.txt, Three.txt etc. I want to be able to load this list into an arraylist so that if I was to check the arraylist its contents would be : arraylist[0] = One arraylist[1] = Two arraylist[3] = Three If anyone could give me any insight into this it would be much appreciated.

  • Remove specific definitions from a variable in PHP

    - by Amit
    Hi everyone, I have a PHP mail script that validates name, email address, and phone number before sending the mail. This then means that the Name, Email address, and Phone fields are Required Fields. I want to have it so that the Name and EITHER Email or Phone are required. Such that if a name and phone are inputted, it sends the mail, or if a name and an email are inputted, it also sends the email. The way the script works right now is it has several IF statements that check for (1) name, (2) email and (3) phone. Here's an example of an if statement of the code: if ( ($email == "") ) { $errors .= $emailError; // no email address entered $email_error = true; } if ( !(preg_match($match,$email)) ) { $errors .= $invalidEmailError; // checks validity of email $email_error = true; } And here's how it sends the mail: if ( !($errors) ) { mail ($to, $subject, $message, $headers); echo "<p id='correct'>"; echo "?????? ????? ??????!"; echo "</p>"; } else { if (($email_error == true)) { $errors != $phoneError; /*echo "<p id='errors'>"; echo $errors; echo "</p>";*/ } if (($phone_error == true)) { $errors != $emailError; $errors != $invalidEmailError; /*echo "<p id='errors'>"; echo $errors; echo "</p>";*/ } echo "<p id='errors'>"; echo $errors; echo "</p>"; } This doesn't work though. Basically this is what I want to do: If no email address was entered or if it was entered incorrectly, set a variable called $email_error to be true. Then check for that variable, and if it's true, then remove the $phoneError part of the $errors variable. Man I hope I'm making some sense here. Does anyone know why this doesn't work? It reports all errors if all fields are left empty :( Thanks! Amit

  • Is there a programming language with be semantics close to English ?

    - by ivo s
    Most languages allow to 'tweek' to certain extend parts of the syntax (C++,C#) and/or semantics that you will be using in your code (Katahdin, lua). But I have not heard of a language that can just completely define how your code will look like. So isn't there some language which already exists that has such capabilities to override all syntax & define semantics ? Example of what I want to do is basically from the C# code below: foreach(Fruit fruit in Fruits) { if(fruit is Apple) { fruit.Price = fruit.Price/2; } } I want do be able to to write the above code in my perfect language like this: Check if any fruits are Macintosh apples and discount the price by 50%. The advantages that come to my mind looking from a coder's perspective in this "imaginary" language are: It's very clear what is going on (self descriptive) - it's plain English after all even kid would understand my program Hides all complexities which I have to write in C#. But why should I care to learn that if statements, arithmetic operators etc since there are already implemented The disadvantages that I see for a coder who will maintain this program are: Maybe you would express this program differently from me so you may not get all the information that I've expressed in my sentence Programs can be quite verbose and hard to debug but if possible to even proximate this type of syntax above maybe more people would start programming right? That would be amazing I think. I can go to work and just write an essay to draw a square on a winform like this: Create a form called MyGreetingForm. Draw a square with in the middle of MyGreetingFormwith a side of 100 points. In the middle of the square write "Hello! Click here to continue" in Arial font. In the above code the parser must basically guess that I want to use the unnamed square from the previous sentence, it'd be hard to write such a smart parser I guess, yet it's so simple what I want to do. If the user clicks on square in the middle of MyGreetingForm show MyMainForm. In the above code 'basically' the compiler must: 1)generate an event handler 2) check if there is any square in the middle of the form and if there is - 3) hide the form and show another form It looks very hard to do but it doesn't look impossible IMO to me at least approximate this (I can personally generate a parser to perform the 3 steps above np & it's basically the same that it has to do any way when you add even in c# a.MyEvent=+handler; so I don't see a problem here) so I'm thinking maybe somebody already did something like this ? Or is there some practical burden of complexity to create such a 'essay style' programming language which I can't see ? I mean what's the worse that can happen if the parser is not that good? - your program will crash so you have to re-word it:)

  • How to prevent shortcuts from firing when form is not active

    - by Erick Sasse
    I open forms inside tabs of a page control. These forms may contain actions with shortcuts. And I want these shortcuts to be fired only when the tab that contain this form is active. I tried to override form's IsShortCut but it's not called. Form's OnShortCut is not called either. I would like to avoid putting code on each action to check this. I'm using Delphi 2010.

    - by Dan
    What is the best way to manage user authentication/sessions in a web app, ideally in a clustered environment, using Spring Framework/MVC? I thought of creating a login bean that creates a jsession for authenticated users and then using AOP to check for the jsession before each controller method inovcation.
