Ms access MS Access查询列隐藏属性

我编写了一些VBA代码，它（a）基于输入变量设置查询的SQL，（b）在数据表视图中打开查询，以及（c）基于另一个表中复选框的“true”/“false”值隐藏或显示列。这将考虑Microsoft开发中心帮助中描述的“ColumnHidden”属性

执行代码时，（a）和（b）按预期工作。然而，在执行（c）时，我在第

fld.Properties（“ColumnHidden”）行得到错误3270，“Property not found”。我一直无法解决这个问题，甚至在尝试开发中心描述的错误处理方法时也是如此。请帮忙

根据Eric Von Asmuth的建议，我在错误处理中添加了代码，因此代码现在显示如下。但我仍然在同一位置收到错误3270。什么都没修好

如果您仔细查看您提到的文章中的示例代码，其中包括错误捕获和创建属性（如果不存在）。这是因为基于不可预测的情况，属性可能存在，也可能不存在

改编自

由于您已经将字段设置为

时，如果字段不存在，则不需要设置错误陷阱

您还可以选择通过i检查属性是否存在
