VB.net Search Database using textbox

Question

I have a textbox in which a user can enter a hotel name and then clicks the Search button. A list of hotels with given name should be displayed upon doing so. Whenever I enter a hotel name and click the button, nothing gets displayed. Below is my code, thank you for any advice:

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    Dim RegDataConn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" & Server.MapPath("App_Data/1202389.mdb"))

    Dim SearchHotel As String = TBSearch.Text

    Dim cmd As OleDbCommand = New OleDbCommand("SELECT Hotel.Hotel_Name, Hotel.Hotel_Location FROM Hotel WHERE Hotel_Name Like '%" & SearchHotel & "%' ", RegDataConn)
    RegDataConn.Open()
    Dim myDA As OleDbDataAdapter = New OleDbDataAdapter(cmd)
    Dim myDataSet As DataSet = New DataSet()
    myDA.Fill(myDataSet, "Table")
    GridView1.DataSource = myDataSet.Tables("Table").DefaultView



End Sub

尝试在查询中添加加号（+），并在百分号（％）之后添加单引号。

 WHERE Hotel_Name Like '%'+" & SearchHotel & "+'%'
