UNIX Quick Start Guides

/in /by

Unix (all-caps UNIX for the trademark) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
From the power user’s or programmer’s perspective, Unix systems are characterized by a modular design that is sometimes called the “Unix philosophy”, meaning that the operating system provides a set of simple tools that each perform a limited, well-defined function, with a unified filesystem as the main means of communication and a shell scripting and command language to combine the tools to perform complex workflows. Aside from the modular design, Unix also distinguishes itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language that allowed Unix to reach numerous platforms.

The .NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library known as Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (as contrasted to hardware environment), known as Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling. FCL and CLR together constitute .NET Framework. Read more.

Using Google Apps

Google Apps for Work (formerly Google Apps for Business) is a suite of cloud computing productivity and collaboration software tools and software offered on a subscription basis by Google.

It includes Google’s popular web applications including Gmail, Google Drive, Google Hangouts, Google Calendar, and Google Docs. While these products are available to consumers free of charge, Google Apps for Work adds business-specific features such as custom email addresses at your domain (@yourcompany.com), at least 30 GB of storage for documents and email, and 24/7 phone and email support. As a cloud computing solution, it takes a different approach from off-the-shelf office productivity software by hosting customer information in Google’s network of secure data centers, rather than on traditional in-house servers that are located within companies.

ASP.NET Issue: The SqlDataSource control does not have a naming container…

/2 Comments/in /by

I have received the following .NET error several times in the past when developing nested databound controls. I have found the solution does not have good coverage on the Internet. The curious thing about this error is that it does not appear until 2nd or 3rd postback on the page.

[box]The SqlDataSource control does not have a naming container. Ensure that the control is added to the page before calling DataBind[/box]

The cause is simple, however. It occurs when you use a ControlParameter on a DataSource that is within another data control. I ran into it again today on a Gridview within a DataList for example. The error occurs because the inner control cannot find the control containing the parameter for some reason.

The solution is simple as well. You must remove the ControlParameter from the DataSource that is inside the other control. This can be accomplished by using a normal <asp:Parameter> and assigning a DefaultValue to it when the outer control binds.
