Director中应用Flash DataGrid组件实现数据库良好功能

Database good function of Flash DataGrid component application in Director

Director和Flash是Macromedia公司推出的多媒体和视频动画强有力的开发工具,是目前设计网页动画和多媒体产品的首选软件。Director侧重做集成设计和复杂交互设计,Flash适合制作动画和简单交互,二者相辅相成,若能把它们的优点结合在一起,在开发的过程中就可以达到事半功倍的效果。Director与Flash的优势是进行网页动画和多媒体产品的开发,与Delphi、Visual FoxPro、Powerbuilder等开发工具相比,在数据库处理和复杂数据显示等方面存在明显不足。根据Director与Flash之间的亲缘关系及通过对它们通讯模式的研究发现,虽然可将Flash的网格(DataGrid)组件直接应用到Director中,但其上可用来直接设置的属性很少,且没有所必需的,如行列设置等。Lingo语言是Director与Flash之间进行沟通的桥梁,通过Lingo语言可实现Director与Flash之间互通控制,依据该特征,利用Lingo语言有效地完成了网格(DataGrid)组件的行列设置,并用其显示了数据库数据,从而使Director得到扩展并解决了Director在显示复杂数据方面的不足。

Director and Flash, which are both powerful developing tools of multimedia and video animation invented by Maeromedia Director, are the prior softwares of the current wedpage animation design and multimedia products. Director focuses on integrated design and complex alternating design, while Flash is more suitable for producing animation and simple alternation. These two softwares are inseparably interconnected, so if their strengths are combined, better effects with less efforts can be achieved in the process of developing. Compared with such developing tools as Delphi. Visual FoxPro.Powerbuilder, Director and Flash are obviously in an inferior position as to database processing and complex data display, for their advantages lie in development of webpage animation and multimedia. As far as the closeness between Director and Flash and the findings of research on their communication modes are concerned, not only are there few immediate setting attributes but also they are not what we necessarily need, for example, setting of lines and rows, though Flash datagrid Component can be straight applied to Director. Lingo language, which bridges Director and Flash, can help them intercontrol. On the basis of this feature, this paper not only completes the setting of lines and rows of datagrid Component with effectiveness but also displays the data in the database by making use of Lingo language so that Director is expanded as well as solving its deficiency in complex data display.
