摘　　要：针对PowerBuilder中通用报表生成不便的缺点,提出了一种利用DataWindow实现报表生成的方法。该方法采用PB的Creat函数将需生成的报表动态创建数据窗口,然后用Describe函数获取数据窗口属性值,用Modify等函数修改数据窗口特定属性,并在数据库中创建包含有该生成报表的报表名、标题名、数据源和生成语法等的数据表。其动态生成报表步骤包括选择生成报表的数据源、选择报表输出字段、打印、保存报表等。Aiming at the existed disadvantages that general reports was created in PowerBuilder (PB), the method of creating report forms by DataWindow is presented in this paper. The dynamic DataWindow was established by Creat() function of PB for forms would created in this method, and then property value of DataWindow was captured by Descnbe() function, the property of DataWindow was modified by modify() function. The data table that contains table name, title name, data source and syntax was established in database. The process of dynamically creating report forms includes data source, output word, printing and save form.
