Exchange Web Services Example – Part 4 – Subscriptions and Notifications
Now that we have succeeded in creating, updating and deleting calendar items and mastered Exchange Impersonation, it’s time to turn our attention to having Exchange notify us about what it is doing. Part 4 of this series is going to provide a detailed code walk-through of some code that leverages the Subscription API.
The example includes two code examples – one for Java programmers and one for OpenEdge programmers. The OpenEdge version writes updates through the OpenClient via the OpenEdge AppServer to an OpenEdge database.
OpenEdge GUI for .NET – Testing the Bridge
Progress Software Corporation has been running a program to test the OpenEdge GUI for .NET bridge with controls that have no user-interface. My company, Intangere, is very interested in this program because we are looking at releasing a control that would make it possible for OpenEdge developers to communicate directly with a Microsoft Exchange Server and receive mailbox updates for an OpenEdge client.
Intangere thus signed up for the program and created a control that mimics the behavior of a real Exchange Web Services control. This test has been surprisingly successful, and this article provides some information about the test and the code and a document that describes its use.
Tools of the Trade – Infrastructure and Process
This post is a follow-up to my last post in which I spoke about the software that I use to build software. In this post, I want to talk about some of the hardware and operating system infrastructure that I have in place and the roll it performs.
As I said in my last post, I do not like to do work that could be automated. A large part of the work that should be automated is the work around the build process. More than anything else, successful software development depends on being able to produce a repeatable build process where the code that is built is thoroughly tested, installed and verified before it is considered stable. To get to the point of understanding how this all works, the hardware and network infrastructure is pretty important. So that’s where I am going to start. [...]
OpenEdge Dynamic OpenClient Java Example
In a previous post, I said I would post an example that demonstrates the use of the OpenEdge Dynamic OpenClient. Well here is the Java version of it. This post is an extensive discussion of the example and how it is structured. Enjoy.
OpenEdge Dynamic OpenClient
In one of the more recent versions of OpenClient, the API that the OpenClient uses is documented so that it is now possible to dynamically construct the proxy calls at run-time. The overarching benefit in this lies in the ability to now define the temp-table definitions on the fly. The Java/.NET code can now define the temp-table dynamically at run-time so that if a change is made to the definition, the client can deal with the change with no impact on the OpenClient source code.
OpenEdge AppServer – Exposing Progress OpenEdge
In 1999 Progress held a user conference in Boston where they showed the any-any-any model. Progress was going to become open. You could connect any client on any platform to any database using a Progress AppServer to handle your business logic. This was a really good idea. The preceding 10 years had taught me that Progress was an outstanding platform for writing the business logic that controlled your application and ensured your data integrity. I was sold.
