基于Delphi的VCL控件开发与实现

摘要

Delphi强大的生命力正是在于它有1流的VCL库和对控件的支持能力，使得编程简单快捷。现在随着Delphi开发者对控件的不同需求，每天都有大量的新的第3方VCL控件发布。
   本次毕业设计就是研究第3方VCL控件的具体开发：以Object PASCAL语言为基础，以DELPHI7.0为开发工具。与其他编译语言相比，PASCAL代码不仅容易阅读，且更容易编写。而DELPHI为PASCAL构造了新的对象语法，功能强大，同时兼容新老版本的PASCAL编译应用程序。
   本讲述了VCL控件开发的1些技术。本人根据在毕业设计过程中所阅读的书籍的积累，结合自己的实际开发经验，来具体阐述控件的开发。重点说明了控件设计思想，难点技术和解决方案，并给出了在开发过程中的1些经验体会。通过此次的毕业设计，本人对控件的开发有了比较清晰的认识，最终开发出了1款日历控件和1款数据感知的日历控件。在以后的学习工作中，我将进1步的完善这方面的知识。

Abstract

Delphi strong vitality lying in it and having first-class VCL storehouses and ability of support to controlling part, make programming simple and swift. With Delphi developers different demands for the controlling part, a large number of  new third party VCL component release every day now.
This graduation project studies the concrete development of the third party VCL controlling part: takes Object PASCAL language as the foundation, regard DELPHI7.0 as the developing instrument. Compared with other compiler languages, PASCAL code is not only easy to read, but also easier to write. And  DELPHI structure new target grammar, powerful, compatible old and new PASCAL of edition compile the application program at the same time. （转载自http://zw.ＮＳＥaＣ.com科教作文网）
The present paper elaborated some technologies of VCL controlling part developing. I, according to the accumulations of the books read in graduation project, combine ones own actual development experience, come concrete argumentation development of controlling part. Having explained the design philosophy of controlling part especially, technology and solution of difficult point , some experience provided in the course of developing is realized. Through the graduation project this time, I have clearer understanding to the development of the controlling part, develop the calendar controlling part that the controlling part of a calendar and a datum perceived finally. Study afterwards in the work, further completion knowledge of in this respect I.
