做过条形码的进
使用了BarTender插件 一直有问题
请教各位怎么搞定条形码的？？？？？？？？？？？？？？

我每次都是从数据库里面将那些条码值读取出来，然后打印。BarTender里面可以设置打印的数据源（有文本文件，数据库文件等等），很简单的。
你说的打印第一个是什么意思?难道是只打印 dt.Rows.Add("a123456")？
[解决办法]
btw = @"D:\Bartend\1.btw";
Process.Start(bartendAdd, "/NOSPLASH /F=\"" + btw + "\" /D=\"" + sn + "\" /P /X");

你可以参考一下 www.qxexpress.com

你是需要生成二维码还是一维码？

具体码表好像当时是从CodeProject里找到的。

有很多第三方的条形码或二维码插件，可以根据字符串生成条形码或二维码
也有的第三方插件如XtraReport里就带有条形码控件，直接拖就可以了。
