现在小弟要做一个发票套打的程序,希望有过这方面经验的提供些经验,如用什么控件或是怎么设置等要点.
我们用delphi的有什么交流的qq群没有,如果有的话,请告知.

最简单的quickRep就可以做到。。另外fastreport也行。。
 
用fastreport,所见即所得,按你要求的格式摆memo即可
 
我有例子,你要留EMAIL我发给你,是用FR的改装版来做的,和FR差不多
 
发票套打最好的办法是自己操纵打印机,打印位置精确
 
你用FASTREPORT,我用这个做过,而且是一个相当复杂的。
最主要是纸张大小和定位,你最好先做个大概,然后到客户的机子上试,因为不同的打印机打出来的效果不一样。
 
各位用的fastreport是什么版本的,从哪里能下载呢.我下载了几个装上都有问题.
 
2.45中文版
 
Grid++Report 3.1,免费的
还有cell就是华表,不过价格有点贵。
 
谁也能告诉我哪个[red]套打控件[/red]能很好用,方便连接数据库,可以让用户自己添加字段,用户方便调整位置,并能保存调整好的位置! 哪位高手帮忙啊! 我找这种控件有一年时间之久了!!!
 
各位楼上有的话 请发一份给兄弟我
