Simple_Application_Framework_for_VCL[1]|中文方案文档站(提供各类方案下载,WORD文档下载,范文,案例等)

in this paper we will discuss a better way of building windows client applications using the borland vcl library. as a result, we will have a library and sample application that will allow us to build module and ui independent windows applications more easily.

the paper is divided into two parts:

			develop a simple application framework. this part is not dependant on developer express libraries and so vcl developers who are not developer express customers can use it.

improvement of the application framework by using developer express libraries. to compile and run the applications provided, you should have installed the following developer express libraries:

			expressnavbar library ver 1.x

			expressbars library ver 5.x

			expressquantumgrid suite ver 4.x

			expressprinting library ver 2.x

issues considered in this paper include:

			the best way of implementing application layouts - using frames inside the main form

			module inheritance using frames

			using the native vcl actions layer

			how long it takes to migrate from one menu&toolbar library to another. using this application framework, you can do it pretty fast, as you only need to modify the code in one module.

			setting up the expressnavbar control at run-time

			using expressbars and expressgrid in the application framework

			adding a printing capability using the expressprinting library

we will develop our application framework piecemeal, starting from the simplest task and at each step we will add functionality, thus keeping code changes as simple as possible. there are 6 steps in total. you can download and compile the project at every step.
