Default SQL query in vb.net 2005

Hi

I am trying to load the details of shops on the form in the labels from my database. These details are first loaded into the listbox using a SQL query.

After the details are loaded onto the listbox I then want to show the details of the item that is selected from the listbox.

The problem I am facing is that it doesnt shows the details of the item selected from the listbox it just dispalys the details of the first item stored in the database.

The code i m using is as follows.

 Public Const strConnection As String = _
"Provider=Microsoft.Jet.OLEDB.4.0; " & "Data Source=../project.mdb;Persist Security Info=False"

Private Sub lstShops_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstShops.SelectedIndexChanged

Dim intRow As Integer
intRow = lstShops.SelectedIndex

Dim objConnection As New System.Data.OleDb.OleDbConnection(strConnection)

Dim strSQL As String = "SELECT * FROM tblShop"

Dim objDataAdapter As New OleDb.OleDbDataAdapter(strSQL, strConnection)

Dim objDataSet As New DataSet
Dim objTable As New DataTable

objConnection.Open()

objDataAdapter.Fill(objDataSet, "AllShop")

objTable = objDataSet.Tables("AllShop")

objConnection.Close()

objConnection.Dispose()

lblStoreName.Text = objTable.Rows(intRow).Item("ShopName")
txtStoreDes.Text = objTable.Rows(intRow).Item("ShopDescription")
lblOpen.Text = objTable.Rows(intRow).Item("ShopOpenTime")
lblClose.Text = objTable.Rows(intRow).Item("ShopCloseTime")
lblLocation.Text = objTable.Rows(intRow).Item("Location")
End Sub

Can someone plz help me with my SQL query?

Thanks

Change your SQL query to something like

SELECT * from tblShop where item = '" & lstShops.SelectedItem.Text &"'"

that should return you the correct row.

hi
Thanks dparsons

You really gave me an idea but the correct SQl statement is without dot text.

SELECT * from tblShop where item = '" & lstShops.SelectedItem &"'"

Chao:)

Thanks for the help.
I've been throwing an exception and couldn't figure out what was 'wrong' with the SQL statement I was sending.
This topic gave me the answer.
