  • Where can I find an ADOExpress tutorial?

    - by mawg
    I'm using Delphi 7, totally new to database programming, and need ODBC. I am told that ADOExpress is a good way to go, and that seems fair enough as it comes with Delphi 7. I need to programatically create, populate, modify and query a database (currently MySql, but that might change, hence ODBC). Can anyone recommend a good tutorial? Thanks.

  • Are there any good sites for blogging about programming?

    - by Jacques Bosch
    I have a few programming articles I would like to write, but I do not have a site of my own - yet ;). Is there a site that is specifically geared toward technical / programming topics, with great functionality and style? Or will I have to go with things like wordpress or blogspot? I would like a site that can track number of views and that has an intuitive commenting system. Any thoughts would be appreciated.

  • "Home" of Javascript similar to python.org?

    - by drewk
    Perl, Ruby, Python, Javascript / ecmascript, PHP are all similar in the sense of being open source, open documentation, multi-platform, etc. Perl has http://www.perl.org Ruby has http://www.ruby-lang.org Python has http://www.python.org PHP has http://php.net Is there a "home" for javascript in the same sense as these other languages? When I say "home" I mean the go-to place for official documentation, specifications, source code of the language, examples, etc.

  • How can I securely check if a username is already taken?

    - by Geo
    I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

  • Convert Office Documents without Office

    - by Benny
    We are in need of converting all MS Office documents to PDF, TIF, or any similar image format with no loss in formatting (these are official documents that cannot have tampering). Is there any way to do this without installing Office on the machine that would do this? Ideally, this would go on a server and run multi-threaded without the overhead of Office Automation. Thanks in advance!

  • Setting processor to 32-bit mode

    - by dboarman-FissureStudios
    It seems that the following is a common method given in many tutorials on switching a processor from 16-bit to 32-bit: mov eax, cr0 ; set bit 0 in CR0-go to pmode or eax, 1 mov cr0, eax Why wouldn't I simply do the following: or cr0, 1 Is there something I'm missing? Possibly the only thing I can think of is that I cannot perform an operation like this on the cr0 register.

  • Advice/suggestions for my first project PHP Classes

    - by Philip
    Hi guys, Any advice is welcome! I have a very limited understanding of php classes but below is my starting point for the route I would like to take. The code is a reflection of what I see in my head and how I would like to go about business. Does my code even look ok, or am I way off base? What are your thoughts, how would you go about achieving such a task as form-validate-insertquery-sendmail-return messages and errors? Please try and keep your answers simple enough for me to digest as for me its about understanding whats going on and not just a copy/paste job. Kindest regards, Phil. Note: This is a base structure only, no complete code added. <?php //======================================= //class.logging.php //======================================== class logging { public $data = array(); public $errors = array(); function __construct() { array_pop($_POST); $this->data =($this->_logging)? is_isset(filterStr($_POST) : ''; foreach($this->data as $key=> $value) { $this->data[$key] = $value; } //print_r($this->data); de-bugging } public function is_isset($str) { if(isset($str)) ? true: false; } public function filterStr($str) { return preg_match(do somthing, $str); } public function validate_post() { try { if(!is_numeric($data['cardID'])) ? throw new Exception('CardID must be numeric!') : continue; } catch (Exception $e) { return $errors = $e->getCode(); } } public function showErrors() { foreach($errors as $error => $err) { print('<div class="notok"></div><br />'); } } public function insertQ() { $query = ""; } } //======================================= //Usercp.php //======================================== if(isset($_GET['mode'])) { $mode = $_GET['mode']; } else { $mode = 'usercp'; } switch($mode) { case 'usercp': echo 'Welcome to the User Control Panel'; break; case 'logging': require_once 'class.logging.php'; $logger = new logging(); if(isset($_POST['submit']) { if($logger->validate_post === true) { $logger->insertQ(); require_once '/scripts/PHPMailer/class.phpmailer.php'; $mailer = new PHPMailer(); $mailer->PHPMailer(); } else { echo ''.$logger->showErrors.''; } } else { echo ' <form action="'.$_SERVER['PHP_SELF'].'?mode=logging" method="post"> </form> '; } break; case 'user_logout': // do somthing break; case 'user_settings': // do somthing break; ?>

  • How to explictely obtain post data in Spring MVC?

    - by predhme
    Is there a way to obtain the post data itself? I know spring handles binding post data to java objects. But if I had two fields that I want to process manually, how do I obtain that data? Assuming I had two fields in my form <input type="text" name="value1" id="value1"/> <input type="text" name="value2" id="value2"/> How would I go about retrieving those values in my controller?

  • Combined sign in and registration page?

    - by Ryan
    This is somewhat against rails convention but I am trying to have one controller that manages both user session authentication and user registration. I am having troubles figuring out how to go about this. So far I am merging the User Controller and the Sessions Controller and having the 'new' method deliver both a new usersession and a new user instance. With the new routes in rails 3 though, I am having trouble figuring out how to generate forms for these items. Below is the code: user_controller.rb class UserController < ApplicationController def new @user_session = UserSession.new @user = User.new end def create_user @user = User.new(params[:user]) if @user.save flash[:notice] = "Account Successfully Registered" redirect_back_or_default signup_path else render :action => new end end def create_session @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default login_path else render :action => new end end end views/user/new.html.erb <div id="login_section"> <% form_for @user_session do |f| -%> <%= f.label :email_address, "Email Address" %> <%= f.text_field :email %> <%= f.label :password, "Password" %> <%= f.text_field :password %> <%= f.submit "Login", :disable_with => 'Logining...' %> <% end -%> </div> <div id="registration_section"> <% form_for @user do |f| -%> <%= f.label :email_address, "Email Address" %> <%= f.text_field :email %> <%= f.label :password, "Password" %> <%= f.text_field :password %> <%= f.label :password_confirmation, "Password Confirmation" %> <%= f.text_field :password_confirmation %> <%= f.submit "Register", :disable_with => 'Logining...' %> <% end -%> </div> I imagine I will need to use :url = something for those forms, but I am unsure how to specify. Within routes.rb I have yet to specify either Usersor UserSessions as resources (not convinced that this is the best way to do it... but I could be). I would like, however, the registration and login on the same page and have implemented this by doing the following: routes.rb match 'signup' => 'user#new' match 'login' => 'user#new' What's the best way to go about solving this?

  • How to improve variable overriding/overwriting in XSL?

    - by ChrisBenyamin
    I want to do the following: Declare a variable Go into a if-statement Overwrite the variable XSL says I can't declare a variable twice, so what can I do to improve this step? Another approach was to check if a variable is set at all. I did this, because i skipped the first step and declared the variable in the if-statement. In another if-statement I wanted to check if the variable exists at all.
