各位大虾，
我们目前的解决方案是用 .Net winform 开发的一个小程序，输入数据，然后操作 Excel ，将数据填充到 Excel 中去，然后直接通过程序打印 Excel。其中的条形码使用的是 Code 39 字体生成的，即 Sakura CD39 字体。条形码的内容也很简单，由数字"1234567890"和连字符"-"组成，所以用 Code 39 一直没有问题。

现在，我们有国外的业务，需要产生一种新的条形码: ]C11040000149:21003:30200
这个条形码里面有中括号 "]" 和冒号":" 还有字母 "C"
我们尝试了以前的方法，都不能实现。
1.最初想使用Code 39 ，但是它不能解析中括号 “]”,即不能对中括号进行编码
2.到网上下载Code 128 ，code 128 好像可以解析上面的字符串，但是一直没有找到免费的。
3.使用Excel 中的控件Microsoft Barcode Control 9.0。因为我们是通过Excel 打印条形码标签的，所以想通过这个来实现。最初是真的可以了，通过设置，他可以解析上面的字符串，但是同时产生了一个新的问题：打印的条形码标签的内容始终不变，始终显示最开始的数据，也就是说如果你想打印修改后的条形码数据，就得将Excel 关闭，重新打开Excel 后才可以打印新的数据，所以这个一直没有得到解决。
4.想使用水晶报表，但是没有使用过，也不知道能不能产生条形码。

上面是我遇到的问题，不知道有哪位大虾能为我指点迷津。非常感谢回贴的任何一个网友。

我自己搞定了，楼上很多朋友说了一些一知半解的答案，却没有真正能解决这个问题，我还是使用了 excel 中的 vba 代码实现了。
那个 barcode 控件很搞笑，要在重新给新值时用 vba 代码改变一下 barcode控件的大小就可以使用新值生效了。如下面的代码：

Private Sub Worksheet_Change(ByVal Target As Range)
BarCodeCtrl1.Value = "]C110" & Cells(5, 5) & ":21" & Cells(12, 19) & ":30" & Cells(12, 18)
BarCodeCtrl1.Height = 41
BarCodeCtrl1.Width = 520
BarCodeCtrl1.Refresh
'改变height 或width值，打印结果才正确
BarCodeCtrl1.Value = "]C110" & Cells(5, 5) & ":21" & Cells(12, 19) & ":30" & Cells(12, 18)
BarCodeCtrl1.Height = 41.25
BarCodeCtrl1.Width = 523.6
BarCodeCtrl1.Refresh
'Sheet2.PrintOut
End Sub

希望能帮助有同样问题的人。

水晶报表目前我一直没有接触过。个人觉得用字体最好。但是就是没有找到这方面的免费的条形码字体

请问使用 Code128 字体怎么做呢？
CODE128码是可以解决的,要用算法算出首尾加进的特殊字符
这个算法在 Excel VBA 中怎么实现呢？

让设定的控件值生效即可,很简单的.

如果知道128码的编码规则那就自己写条码组件。
这是基类代码
