私人小组TextBox5_TextChanged(发送者为对象,例如作为EventArgs的)处理TextBox5.TextChanged

       试试¥b $ b            Dim table1 As New DataTable

            Dim SDA1 As New SqlDataAdapter

            Dim bSource1 As New BindingSource



            connection.Open()

            Dim query As String

            Dim ds1 As DataSet =新数据集

            query =" select * from SAPCONSUMABLE WHERE描述LIKE'%" &安培; TextBox5.Text& "%'"

            command = New SqlCommand(查询,连接)

            SDA1.SelectCommand = command

            SDA1.Fill(ds1,"SAPCONSUMABLE")

            bSource1.DataSource = table1

            ComboBox3.DataSource = ds1.Tables(" SAPCONSUMABLE")

            ComboBox2.DataSource = ds1.Tables(" SAPCONSUMABLE")

            ComboBox4.DataSource = ds1.Tables(" SAPCONSUMABLE")

            ComboBox5.DataSource = ds1.Tables(" SAPCONSUMABLE")



            SDA1.Update(table1)



            connection.Close()



        Catch ex As SqlException

            MessageBox.Show(ex.ToString)

       结束尝试



   结束子

Private Sub TextBox5_TextChanged(sender As Object, e As EventArgs) Handles TextBox5.TextChanged
        Try
            Dim table1 As New DataTable
            Dim SDA1 As New SqlDataAdapter
            Dim bSource1 As New BindingSource

            connection.Open()
            Dim query As String
            Dim ds1 As DataSet = New DataSet
            query = "select* from SAPCONSUMABLE WHERE Description LIKE '%" & TextBox5.Text & "%'"
            command = New SqlCommand(query, connection)
            SDA1.SelectCommand = command
            SDA1.Fill(ds1, "SAPCONSUMABLE")
            bSource1.DataSource = table1
            ComboBox3.DataSource = ds1.Tables("SAPCONSUMABLE")
            ComboBox2.DataSource = ds1.Tables("SAPCONSUMABLE")
            ComboBox4.DataSource = ds1.Tables("SAPCONSUMABLE")
            ComboBox5.DataSource = ds1.Tables("SAPCONSUMABLE")

            SDA1.Update(table1)

            connection.Close()

        Catch ex As SqlException
            MessageBox.Show(ex.ToString)
        End Try

    End Sub
