在PB开发中利用PSR文件实现打印位置自由调整

Using the PSR Report File to Realize Printing Position Adjusted at Will by Customer in Powerbuilder Environment

用powerbuilder开发管理信息系统会涉及到一些报表和表格的打印,工作中经常会遇到用户根据需要随时调整打印位置的情况,普遍的方法是由编程人员重新在源程序中调试打印位置,等位置固定以后编译发行给用户使用,这样十分不方便.通过对数据窗口对象以及PSR报表格式文件结合使用,以及使用数据库大文本字段来存取blob类型数据的深入研究,实现了用户自己随意调整打印内容的位置等格式信息,从而大大减轻了程序设计人员的维护工作量.

Programers Sometimes meet some questions about printing a few reports or tables when using powerbuilder design MIS,Customers always want Adjust content's printing position themselves as their needs,The general solution is to changed again in the source program by programming personnel,Such is acted as very miscellaneous and trivial,extremely not convenient.Be put into use by the fact that the document combines to the data window marriage partner and the PSR report form,be studied in a deepgoing way as well as using big data base version syllables to come to the access blob type data's,Have realized a consumer self adjusting the content printing position at will,and have lightened personnel's upkeep amount of work thereby greatly.
