VBA使用宏将22个管道(|)添加到文本文件

Question

我希望你能帮助我编写一段代码，它的作用是从两个 Excel 工作表中获取信息并将其放入两个文本文档中以供在数据库中使用。

我的代码工作正常，但在数据库中添加了 22 列，其中文本文件注定要被使用，因此我需要在记事本文件中的公司 Id 之前放置 22 个管道(|)

第一张图片是Excel表格，工作人员可以在其中输入数据

第二张图片显示了 Excel 工作表，其中数据从“ session 结束模板”中排序，宏选取数据以转换为文本。该排序表称为“Template-EFPIA-iTOV”，灰色的列是宏图片的内容

在下图中，您可以看到公司 ID 是“Template-EFPIA-iTOV”中的最后一列

下面是工作表“Template-EFPIA-iTOV”在文本中的表示方式

这是文本文件中的公司 ID

因为目标数据库现在在公司 ID 之前有额外的 22 列，所以我需要我的宏在文本文档中的公司 ID 之前放置 22 个管道 (|)。

Excel 工作表“模板 EFPIA 客户”也转换为文本，但这很好，不需要修改。

我的代码如下。一如既往，我们非常感谢任何帮助。

由于您的代码设置为使用 generate_file 的这一部分来检测列数:

Do While (Trim(MyWkSheet.Cells(1, NBCol + 1)) <> "")
    NBCol = NBCol + 1
Loop

...然后将所有行动态保存到管道分隔的文本文件中，我强烈建议将新列添加到工作表中，即使它们将是空白的。

但是，如果您想临时配置它来完成工作，您始终可以向每个输出行添加 22 个管道。将 generate_file 循环中的 OUTFILE_WRITELINE sOut 替换为 OUTFILE_WRITELINE "|||||||||||||||||||||"&sOut.

如果您确实决定使用这个丑陋的 hack，请确保您非常仔细地对其进行注释，以便您和代码的任何其他维护者可以在需求不可避免地再次发生变化时找到并修复它。
