Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.

There arent enough of us to do the full testing we should do on new features we build for our website, plus to just make sure things keep on functioning as they should. We need to set up automated testing of all of our website features, like logging in, getting special pricing levels based on who you are, shipping API's functioning as they should, general website functionality etc. Is Selenium a good way to go? If so, can somebody please give me a bullet point list of how to get started and implemented? This is for a large website on LAMP stack. Thanks very much.

A small real estate firm is looking to have a website that would display their property listings, blog, documents and other static information.
It needs to be mobile compatible as well.
They want to post the listings themselves.

Is there a company that produces these sites?  Something that runs under WordPress?

Thanks.

Hi everyone,

I'm trying to install the Microsoft Lync Web App Plugin.  I get to a point during the process where I'm prompted to run the plug in, in order to get audio and video.  However, as the progress bar gets to about 90% complete a dialogue box generates and indicates the "The specified account already exists", then closes and the users is never able to reach their meeting.

Here are some details surrounding the setup -

  • The device is a Dell laptop
  • The OS is a WIN 7 64-bit platform
  • Running Microsoft Office 2013
  • This is a domain environment
  • The user is a standard user on the laptop
  • I, as an admin, have installed the Skype Meetings App as I can see it listed in Control Panel
  • I've also got the latest version of Silver Light installed
  • I've also uninstalled and reinstalled the Skype Meetings App a couple times and get the same dialogue box - Account Already Exists
  • I've cleared the cache and history
  • We don't run Office 365

I'm a bit stumped.  Any thoughts?

Thanks for your help.

Hi,  I'm creating a PHP and MySQL web application for a client. I'm a fairly new web developer.
Is there a way to add page titles and meta tags dynamically? It's a small application. I'm not using a Framework.
I saw a couple of possible solutions on google, but am not sure what the easiest and most efficient way of doing it would be.

Possible Solution #1, add variables in my header.php page and then on each respective page for example about, contact etc... add those variables above the include statement.
Here is my header.php code:

?>

<!DOCTYPE html>
<html lang="en">
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
	<meta charset="utf-8">
	
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<meta name="description" content="<?php echo $meta_description; ?>">
	<meta name="author" content="Ryan Sacks">
	<link rel="icon" href="img/favicon.ico">
	
	<title><?php echo $page_title; ?></title>
	
	<!-- Bootstrap core CSS -->

Hi,
I'm fairly new to php and mysql but I'm creating a PHP and MySQL web application for a client. I have a register.php page with the following form fields:
Contact Name, Phone, Email, Password, Confirm Password, Ticket Holder Password and Ticket Holder Confirm Password, where Users can register/sign up to use the app. Once they do register, they get redirected to admin_login.php page where they can login and get full access to the app and various other pages I've created.

My Problem:
My Password validation functions aren't working and I'm not sure why. I want the passwords to be a minimum of 8 characters, contain one upper and lowercase letter, a number and a special character. I'm using a regular expressions code that I found online. What I want is to validate the Password fields, so if the User enters a password that meets the criteria mentioned above than it should INSERT the data INTO the database, if it doesn't meet the Password criteria mentioned above I want to display an error message saying: "Password must be minimum of 8 characters, contain one upper and lowercase letter, a  number and a special character". I'm new to using php functions and how to call them properly.

This is the code in my functions.php page:

<?php

// FUNCTIONS.php

// clean the form data to prevent injections

/* Built in functions used:
   trim()
   stripcslashes()
   htmlspecialchars()
   strip_tags()
   str_replace()
*/

function validateFormData($formData) {

Hello experts,
We have intermittent browsing issues (accessing internal and Saas applications) in our company, and just wanted to find out for your expert advices as to how you guys go about troubleshooting it. Does it always require a 3rd party solution to determine the bottlenecks.

One of instances are both IE and chrome (both on VDI and physical machine), goes to page isn't working if it stays for a certain period of time.

Thoughts?

Thanks a lot.

Hello

I am trying to connect Zapier on an MS SQL 2014 instance I am running on one of our servers.

I can connect fine using heidisql.

When connecting from Zapier I get an authentication error:

(pyodbc.ProgrammingError) ('42000', "[42000] [unixODBC][FreeTDS][SQL Server]Login failed for user 'someuser'. (18456) (SQLDriverConnect)")

Open in new window


So this means that the network connexion itself is working but somehow their Python based connector doesn't manage to authenticate.

We used mixed mode authentication on said sever and I have tried both SQL user and domain user to no avail... Using a complex password as per their suggestions.

Any suggestion / info most welcome (as their support is not too helpful on this one).

I have Elasticsearch 6.4.3 and Kibana 6.4.3 installed on Debian 8 Jessie.

I've looked into X-Pack and Shield, which both seem to be mostly concerned with security within Elasticsearch, and how to control security BETWEEN Elasticsearch and Kibana.

I don't really need security on the backend between Kibana and ES. However we would like the Kibana web page to be world accessible with a login page.

Is it possible to implement ONLY a login page for the Kibana site?

Hi,
I have a Table called game with 4 columns:
clock_first_goal, clock_last_goal, clock_first_penalty, clock_last_penalty

and a second Table called tickets_one with 5 columns:
clock_one, clock_two, clock_three, clock_four, clock_five
where I've imported random clock times between 0 and 20:00 minutes that of a NHL period.
There are 1200 total times (60 seconds x 20 minutes) in 5 columns so there are 240 records in this Table.

In my application I have a page called enter_games.php. What I want is when the admin submits the times for First Goal, Last Goal, First Penalty and Last Penalty, I want to check if any of these values match the values in the tickets_one Table. If they do I just want to echo "we have a match!", if not I want to echo "no match".

I'm not sure the best way to do this if it should be a Join, if statement or loop etc... I think it can be done with an if statement.
I'm somewhat new to php and mysql. This is the section of the code I'm trying to get to work:

// find matching results
// query the database with client ID
$query = "SELECT * FROM tickets_one";
$result = mysqli_query( $conn, $query );

// if result is returned
if( mysqli_num_rows($result) > 0 ) {

    // we have data!
    // set some variables
    while( $row = mysqli_fetch_assoc($result) ) {
        $time1    = $row['time_one'];
        $time2    = $row['time_two'];
        $time3    = $row['time_three'];
        $time4    = $row['time_four'];
        $time5    =

Dear experts

Our company would like to setup open source OT management system that allows us to do following:

1. When employ wants to do OT, Start time must be submitted first and then it will only be reflected to system once administrator approved.
2. Later when employee finish job, he or she can set the end time, and there should be something that allows emplyee to upload service report that contains start and end time signed by our customers.
3. After setting end time, it should show total OT - hours and we should be able to generate monthly OT for each employee.

Plz advise something that is opensource or even if need to pay, it should be something not very expensive.

Hi,
I'd like to find matching results between 4 columns in one table and 5 columns in another table.
I have one table called game with 4 columns:
clock_first_goal, clock_last_goal, clock_first_penalty, clock_last_penalty

and a table called participants with 5 columns:
clock_one, clock_two, clock_three, clock_four, clock_five

Everything in these columns are numbers like 4:16, 8:47, 13:02 etc clock times of a period of an NHL hockey game. I think I should be using an Inner Join for this however, it's not working, it's just displaying all of the times in the database instead of just the matching results within those columns.

Please take a look at the screen shot attached to see what I mean.

Here is the code I have so far:


$query = "SELECT * FROM participants AS p INNER JOIN game AS a ON p.game_date = a.game_date WHERE a.user_ID='$userID'";

 

$result = mysqli_query( $conn, $query );

 

                    ?>

                                                               

                                                                                <?php

                                                                                if( mysqli_num_rows($result) > 0 ) {

 

                                                                                                // we have data!

                                                                                                // output the data

I am using visual studio 2010 for a  web application with gridview populated by dataview source of which is a datatable.
One of the fields diffimt is numeric field defined as follows:
 DataColumn diffimt = new DataColumn("diffimt", typeof(int));
I wanted the dataview and hence the gridview to be sorted in the ascending order of the field
dView.Sort = "diffimt ASC";
After the sort command, gridview is source to dataview and then databound with the following commands
dView.Sort = "diffimt ASC";

                GridViewVa.DataSource = dView;
               GridViewVa.DataBind();

But it is sorting as if it is a text field.  Screeshot is depicted in the attached file.  As for my requirement, the sorting should be
12,13,102,102,107…….. Not 102,102, 107 …
Can anyone help in fixing the problem

This course will introduce you to Ruby, as well as teach you about classes, methods, variables, data structures, loops, enumerable methods, and finishing touches.

I manage a bunch of websites that mostly use Coldfusion. Each website is located in its own directory on the server and they all use the same version of the code and they each have their own database. I am trying to figure out what is the best way to update all of the sites when I make a change to the code. Right now I have created a directory on the server that contains the changed files and then I use directoryCopy to copy over the new files. My code looks something like the following:
<cfset temp = directoryCopy("_UpgradeCode","website_to_update_directory/",true,"*.*")>

Open in new window


One issue that I have is that I don't know if there were any problems copying over the code.

Can anyone suggest a better way to update websites? I am hoping that this can be done in an automated way so that I can just call a function or something and then it automatically updates all of the sites. I have created a list of sites to update that can be passed to the function.

Thank you for any help that you can provide about this.

I need to change a gridview datasource/connectionstring based on session parameter/login.

Just a little background, we have an in-house software that generates an .mdb database file and then uploads it to our hosted database-driven website via FTP. Each of our customers get their own .mdb file and a login to the website. The website is designed to show only their assigned .mdb. But the website has limited capabilities.

So I was tasked to update the website and found out that it uses .asp, but I am not well versed in VB script and found that creating an .aspx web application is easier.

Now I'm developing a web application in Visual Studio that utilizes the same database but with added features such as sorting, paging, and filtering based on keyword searches.

I've finished creating the login part (with sessions), and I've been able to create a page that displays data on a gridview. My problem now is that I don't really know how to change the gridview datasource based on login/session.

By the way, the database for login information is also an .mdb and is also uploaded by our in-house software. If we need to add new users, we use the in-house software to update the .mdb and then upload it to the website. There are 3 columns in the database table, username, password, and client code. I would like to use the client code to pull the correct database file because each of the database files contain a specific client code already.

Please assist. Thanks!

I am working to create a login prompt and I do not want the browser to offer the remember username and password option for the user. I am using a text box for the username field and a password box for the password field. Anytime I use a password box the browser prompts the option whether to remember username and password or not. I would like my users to type in those information each time they login. Is there any way I could use a text box to accept password and mask the characters in that textbox as a password character so that the browser does not prompt the remember username and password option?

Hi , I need an advise .
Do anybody know , what is the most popular architecture for .Net WEB application?
I mean before 2008 I use
ASP.NET 3.5  + Adjust  Toolkit cl [b]- front end ( view)
Typed DataSet  + Busies Logic CS classes middle tier ( model)
Public generic  cs class injected into Code Behind of every page was responsible  for binding / back binding
ASP.NET controls  to Typed Dataset  ( controles)
Public generic  cs class was responsible  to fill out Typed Datset data from SQL Server ( DAL)
Back end is always was SQL Server
Export / Import of the data was always via WEB Services  or sql jobs  which were run  from the last data received identity  (for performance point)
Right now so many Framework.

Do you   how use them  the most optimal way?
I mean what is the best way  to  implement
1)Most  efficient front end
2) Middle Tier with Business logic
3) Data  Access Layer
4) Data Exchange (Export/ Import) with   different clients
