Using DLLs when you distribute your application allows you to replace individual components of your application suite without having to kick all users out of the program. For instances, the Accounts Payable module can be replaced without shutting down the shipping department.
DLLs can be very useful in many situations and once you learn a few tricks, are really quite simple. We will talk about how to structure your application to use DLLs to make updating installed applications much simpler to manage and keeps customers working happily.
It's the middle of the summer, so let's set the serious work aside and have a little fun for a change. I bet we can still learn something...
First, I found an old OpenGL program that displays fireworks and thought it would be fun to look at the code and watch splashes of color explode--especially since some major fireworks displays in the area were canceled this year due to budget constraints.
There is a saying that any technology that is sufficiently advanced is indistinguishable from magic!
There are a lot of new features and language enhancements in the last three versions of Delphi that may seem like magic to those who do not know about them. And there are some features that have been in Delphi for a long time that some don't realize are there.
Anders Ohlsson from CodeGear will be at our group in Portland to talk about the latest Delphi products for both Windows 32 and .NET, show how to move your existing projects to the new environments, demonstrate modeling techniques to improve your code, and give you insight on rapidly creating web applications.
There will be discounts on Delphi 2009, C++Builder 2009, or RAD Studio 2009. And one lucky winner will walk away with a free copy of RAD Studio 2009 Pro!
The end of the year is fast approaching. Since we only meet every other month, this is the last meeting this year. I had asked CodeGear to come out and show us Delphi 2009 and talk about new developments, but that doesn't seem to be an option for us right now.
This month, the trials and tribulations of creating and running DLLs in Delphi will be discussed. We will talk about whether or not you really need DLLs, how to handle versioning, and interface design.
We don't have a formal presentation planned, but will discuss whatever topics arise from the group. Delphi on a laptop will be available to write sample programs wherever the night's discussion takes us.
This month we'll explore some custom-written non-visual components that have been useful in several projects, encapsulating common functionality for ease of use and consistency. This isn't a new topic, but is a great starting point to discuss unit testing. Unit testing is not a new topic either, but one that more people should look at.
Studying these two topics together could branch in various directions, depending on questions and preferences from the audience. We may even continue the discussion at our March meeting if need be or dive into more detailed areas of study.
We welcome anyone interested in Delphi from Portland, Troutdale, Oregon City, Milwaukie, Clackamas, Tigard, Beaverton, Gladstone, Newberg, Sherwood, Hilllsboro, Tualatin, Lake Oswego, West Linn, Wilsonville, Salem, Corvalis, Eugene, Springfield, and Vancouver, WA and surrounding areas.
Proudly supporting Delphi from Embarcadero!
