Where Is My Data and How Do I Get to It?

by Chris Backhouse Christopher Liley David Duncan | October 2013 | Enterprise Articles Microsoft

This Article, by David Duncan and Christopher Liley, authors of Microsoft Dynamics GP 2013 Reporting, Second Edition, explains that, as a developer or consultant who has been assigned the task of filling user requests for reports should be aware that ultimately the very first question after deciding on the reporting tool is, "Where is my data and how do I get to it?"

Knowing where to begin is a critical first step in the development process. The aim of this article is to provide helpful tips for finding and locating data in the Dynamics GP 2013 ERP system and company databases. Although we'll discuss some reporting tools that do not require us to know the SQL database structure for Dynamics GP companies, it is still helpful to understand how GP stores its data.

In this article, we will discuss the following:

  • Differences between the system database and company databases
  • Conventions that are helpful to know and understand when it comes to Microsoft Dynamics GP 2013 data and how it is stored
  • Using Resource Descriptions as a tool for finding data from within GP 2013
  • Utilizing additional tools, such as the GP 2013 SDK and Support Debugging Tool, to find our data

Why Do We Need Specialist Security Distros?

by Mayank Sharma | February 2008 | Linux Servers Open Source

Many popular distributions, community-oriented and otherwise, take security very seriously. They have dedicated security teams that go over individual packages before they're rolled into a final release. To make sure you don't have any loose ends, these distributions and many other individual Open Source projects also publish an endless stream of security advisories and updates. Add to this security mechanisms like SELinux, AppArmor, and the upcoming TOMOYO Linux, and SMACK, and you know they mean business. So what room does this leave for specialist security distros?

Windows Azure Diagnostics: Initializing the Configuration and Using a Configuration File

by Neil Mackenzie | August 2011 | Cookbooks Enterprise Articles Microsoft

The default configuration for Windows Azure Diagnostics captures some data but does not persist it. Consequently, the diagnostics configuration should be modified at role startup.

Windows Azure Mobile Services - Implementing Push Notifications using

by Geoff Webber-Cross | January 2014 | Enterprise Articles

In this article by Geoff Webber-Cross, author of the book Learning Windows Azure Mobile Services for Windows 8 and Windows Phone 8, we will have a look at how push Notifications allow us to expand our application's user experience outside the bounds of the app with live tile updates, toast notifications, and badges in Windows 8. Windows Azure Mobile Services makes it very easy for us to trigger notifications via Windows Notifications Service (WNS) (for Store apps), Microsoft Push Notification Service (MPNS) (for Windows Phone 8 apps), Apple Notifications Service (ANS), and Google Notifications Service (GCM). We're going to discuss how to configure Windows 8 and Windows Phone applications to allow notifications, send different types of notifications using scripts, and create a list of devices to manage our user's notification channels.

Windows Azure Service Bus: Key Features

by Riccardo Becker | December 2012 | Enterprise Articles

Windows Azure Service Bus offers features that are not offered by any other cloud platform on the market. One important feature is the Service Bus that enables you to connect your on-premise services to Windows Azure services and beyond. The Access Control Service enables you to easily authenticate users without having to write complex authentication code ourselves. By using Windows Identity Framework (WIF) and supporting identity providers such as Live ID, Yahoo, and Facebook, it will be easy to use these identity providers as the main authentication mechanism in our own services.

In this article by Riccardo Becker, author of Windows Azure programming patterns for Start-ups, we will provide a systematic guide on how to integrate with Facebook. AppFabric also contains AppFabric applications, an easy way to develop and deploy composite applications. Another interesting feature is the caching feature that AppFabric offers.

Windows Development Using Visual Studio 2008

by Stefan Björnander | July 2009 | Microsoft

The development environment of choice in this article by Stefan Björnander is the Visual Studio from Microsoft. In this article we also study the Microsoft Foundation Classes (MFC).

  • Visual Studio provides us with a few Wizards—tools that help us generate code. The Application Wizard creates an application framework (a skeleton application) to which we add the specific logic and behavior of our application.
  • When developing a Windows application, the Document/View model comes in handy. The application is divided into a document object that holds the data and performs the logic, and one or more views that take care of user input and display information on the screen.
  • When an event occurs (the user clicks the mouse, the window is resized) a message is sent to the application, it is caught by a view object and is passed on to the document object. There are hundreds of messages in the Windows system. However, we only catch those that interest us.
  • The device context can be viewed both as a canvas to paint on and as a toolbox holding pens and brushes.
  • When we finish an application, we may want it to occur in the same state when we launch it the next time. This can be archived by storing vital values in the registry.
  • Serialization is an elegant way of storing and loading values to and from a file. The framework takes care of naming, opening, and closing the file, all we have to do is to fill in the unique values of the application.
  • The cursor has different appearances on different occasions. There are several predefined cursors we can use.
