小编给大家分享一下mshflexgrid如何联动数据库删除，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

Mshflexgrid属性运用

MSHFlexGrid1.Row 返回当前选中的行号

MSHFlexGrid1.TextMatrix(MSHFlexGrid1.Row, 0)代表返回指定行的第一列的值

删除后的刷新思想

1、数据库删除后，重新进行一遍查询（不推荐，消耗性能大）

2、数据库删除后，直接在mshflexgrid上面进行删除指定行，使用语句MSHFlexGrid1.RemoveItem MSHFlexGrid1.Row

RemoveItem方法后面添加一个索引值，就可以删除指定行

sql = "insert into [users]([username],[password]) values('" & Text1.Text & "','" & Text2.Text & "')"
