We're using the Financial Force for our accounting package within Salesforce, and have written a new class for a change we're implementing which has nothing to do with the Sales Invoice object. However, when we tried to deploy the change set, an error occurred on the already deployed trigger on the Sales Invoice object with a working Test Class. The error message on the deployment log shows:

What is the difference between "Primary Key" and "Unique Key" in SQL?

Sep 15, 2017 By Webtraffic Exchange SQL , Databases 0 Last Modified on 2024-02-21

I've had a chance to with a Postgres database and came across a table with two primary keys. This intrigues me to look up a definition of primary and unique key. I always thought there would only be one primary key in a table, and the values have to be unique. But, what I saw in the PostgreSQL v8.1.23 was something otherwise. It allowed duplicate entries, and also allowed multiple primary keys in a table. Is this possible? Yes, it's called composite Primary Keys. Composite primary keys (multiple primary keys) makeup uniqueness in a table row -- which means composite primary keys work together to provide uniqueness.

One of the servers we manage has been compromised, and hosting malware according to Kaspersky Anti-Virus software. The site uses a number of open-source applications such as WordPress, Gnuboard, and phpLinkDirectory. We initially thought it would be either the .htaccess or base64_encode exploit, but after close examination, we found that a plain javascript snippet was inserted into one of the Gnuboard include files (bbs/visit_insert.inc.php).

Zend Framework without MVC

Jul 15, 2017 By Webtraffic Exchange Framework 0 Last Modified on 2024-01-16

The reasoning for using a framework such as Zend Framework (ZF for short) is to speed up the development process, make the application extensible, and make use of the design patterns such as MVC. I think MVC is great, it separates the models, views, and controllers and makes the entire development process very clean. If MVC is great, why would you use Zend Framework without MVC?

Perl string quotation operators (q, qq, qr and qx)

Jun 15, 2017 By Webtraffic Exchange Programming 0 Last Modified on 2024-01-16

In scripting programming languages such as Perl, PHP, and Python use string quotation extensively. To include a single or double quote inside the string quotation, you'll have to escape the character with a backslash. Perl string quotation operators (q, qq and qx) let you avoid putting too many backslashes into quoted strings.

Multiple Constructors in PHP

Apr 15, 2017 By Webtraffic Exchange Programming 0 Last Modified on 2024-01-16

In most object-oriented programming languages such as Java, C++, and C#, you can define multiple constructors each having different signatures. The class calls the correct constructor based on the number of parameters, and data type of input parameters. In PHP5, however, you can have one and only one constructor. Constructor in PHP is defined with a reserved keyword, __construct(). If the __construct function doesn’t exist, PHP5 will search for the old-style constructor function by the name of the class.

How do I find a dual DVI-D (dual link) graphics card for 2560x1440 resolution?

Mar 26, 2017 By Webtraffic Exchange Operating Systems 0 Last Modified on 2024-02-02

With high-end LCD and LED monitors becoming affordable, I've opted to upgrade my current 21" monitors with a larger 27" capable of displaying 2560 x 1440 resolution. I have a Dell Optiplex 3010 computer which has 1 x VGA and 1 x HDMI (they are only capable of displaying 1920 x 1050 resolution). I've opted to shop for a new graphics card, but it wasn't easy to choose one as descriptions of the products shown on major websites weren't clear enough to ensure compatibility.
