【英文标题】：Using Michael Ciurescu (CVMichael) Code128 Barcode VBA, Certain Numbers Don't Work

【发布时间】：2014-06-03 07:13:53

【问题描述】：

我是新来的……潜伏已久，但这是我第一次无法找到答案或找到解决方案。

我正在使用从该站点提取的 code128 条形码 VBA 脚本：

' * Michael Ciurescu (CVMichael) 制作 * '由 Paulo Cunha (pcunha) 修改，以便在 2011 年 5 月 16 日在 word 或 excel 上使用 char128.ttf 'http://grandzebu.net/informatique/codbar/code128.htm中的字体

Generating Code 128 Barcodes using Excel VBA

我一直在使用它，但现在我一直在扩展输入，我发现下面列出的条码不起作用：

120096 120660 220081 420058 420059 420061 420062 420063 420067

有其他人使用过此代码并遇到过类似问题吗？

【问题讨论】：

所以我一直在玩这个。如果我强制它使用 Bset，我已经得到了所有上述数字。现在唯一的问题是数字 120762。这产生了一个模 103 = 0。我可以连接一个空格或 chr(32)，但条形码仍然无法读取。我不知道如何处理模 103 = 0。有人有任何见解吗？

好的。我在代码中有一个“hack”解决方案。结果是在 SetC 和 CurrChar = 00 或 (ArrIndex = "0") 中它试图连接一个空格。这不起作用，因为连接的下一个字符会覆盖空格。我输入了一个可怕的 If 语句，并将 chr(212) 连接起来（验证它有效）。此外，我正在为 CheckDigit 执行相同的例程（同样的问题）。
