Question

我有一个包含列的列表视图：

ID，Contact_Name，Contact_Number，DateAndTime，Messages

我想使用＆＃34;日期＆＃34;来搜索列表视图。在DateAndTime专栏中。

使用textbox_textChanged：

Try


 Dim sqlQuery As String = "SELECT From SentItems WHERE DateAndTime like '%" & TextBox6.Text & "%'"


            Dim sqlCommand As New OleDbCommand
            Dim sqlAdapter As New OleDbDataAdapter
            Dim Table As New DataTable

            With sqlCommand
                .CommandText = sqlQuery
                .Connection = cn

            End With
            With sqlAdapter
                .SelectCommand = sqlCommand
                .Fill(Table)

            End With
            lvSent.Items.Clear()

            For i = 0 To Table.Rows.Count - 1
                With lvSent
                    .Items.Add(Table.Rows(i)("ID"))
                    With .Items(.Items.Count - 1).SubItems
                        .Add(Table.Rows(i)("Contact_Name"))
                        .Add(Table.Rows(i)("Contacts_Number"))
                        .Add(Table.Rows(i)("DateAndTime"))
                        .Add(Table.Rows(i)("SentMessage"))
                        .Add(Table.Rows(i)("Status"))


                    End With

                End With
            Next

        Catch ex As Exception

        End Try

textbox6中的日期格式= M / d / yyyy

listview中的日期格式= M / d / yyyy

问题是每次我搜索并找到（匹配的）结果。列表视图中的所有项目甚至与文本框中的文本都不匹配。请帮帮我们......谢谢....

像这样更改您的查询

Dim dt as string
dt=Format(CDate(TextBox6.Text),"yyyy-MM-dd")
Dim sqlQuery As String = "SELECT From SentItems WHERE DateAndTime like '%" & Format(CDate(dt),"yyyy-MM-dd") & "%'"

按日期格式搜索ListView
