在Vb6.0运行时错误3021中，bof或eof为true [英] IN Vb6.0 runtime error 3021 either bof or eof is true

问题描述

尊敬的先生，
我正在vb 6.0中制作软件.我正在制作过滤器表格.
在此软件中.问题是当我输入日期并单击确定按钮时，我在文本框中输入日期范围时，它给出错误3021，要么bof或eof为true，要么当前记录被删除.
但是当我在文本框范围内输入任何接收号码时，它不应给出任何错误并显示结果.

推荐答案

这很可能意味着带有日期参数的查询未返回任何记录.

在使用RecordSet之前，应检查是否没有记录.

It most likely means that your query with a date parameter is returning no records.

Before you use the RecordSet you should do a check for no records.

If Not rs.BOF Adn rs.EOF Then

''Your code here

End If

您可能需要在日期值周围添加引号

You might need to add quotes around the date value

Dak.RecptDt<=""" & CDate(Text4.Text) & """"
