Question

我正在尝试通过使用VBA获取在Excel中生成的Code 128条形码。我找到了一个VBA类，有人通过VBForums制作和共享（后来修改为与Excel VBA一起使用），但是我遇到了让它运行起来的问题。

如果我在启用Excel宏的电子表格中使用以下代码，则在尝试对任何输入使用Code128_Str（）函数时会出现#VALUE错误。

我缺乏正确调试代码所需的技能。如果这个脚本可以纠正，我认为这对许多尝试这样做的人来说非常有用。有问题的脚本使用免费字体生成相关的Code 128输出条形码。

Answer 1

以下是如何使用它你需要

模块（存储可以从Excel调用的UDF函数电子表格）
类模块（存储类对象）

<强>模块 Class1是类模块的名称

Public Function Code128_Str(ByVal Str As String) As String
Dim c As Class1
Set c = New Class1
Code128_Str = c.Code128_Str(Str)
End Function

然后在SpreadSheet中，在任何单元格中，您都可以调用 =Code128_Str("TESTING") 要么 =Code128_Str(A1)

Answer 2

拉里的代码很精彩，但我只发现了一个小问题。（我会对他的回答发表评论，但我没有足够的声望点）。当我编码双零时，我遇到了问题。例如“1200”。 “00”转换为空格。代码中有许多地方可以“修剪”空格或“替换”空格。当我尝试编码“1200”时，生成的条形码只会是“12”。为了解决这个问题，我删除了适用的“修剪”和“替换”，如下所示。下面的代码只是类模块。有关模块代码，请参阅Larry的帖子。
