Database Error

Can Anyone help me with this problem. I have been trying to connect my vb.net project to a sql database for two weeks. Thanks

Option Explicit On

Imports System.data.sqlclient
Imports System.Data

Public Class frmMain

Inherits System.Windows.Forms.Form

Dim cn As New SqlConnection
Dim mycommand As New SqlCommand
Dim myDS As DataSet = New DataSet
Dim Mydatagrid As New DataGrid
Dim da As New SqlDataAdapter
Dim cmdtext As String = "select itemnumber from auto"


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

cn.ConnectionString = "integrated security=true;initial catalog=justin"

'cn.Open() ****this gave me an error so I commented it out****

Dim cmdtext As String = "select * from [auto]"
Dim da As New SqlDataAdapter
da.SelectCommand = New SqlCommand(cmdtext, cn)

Dim dt As New DataTable("Table Auto")
da.Fill(dt)*****this is highlighted green and says:an unhandled exception of type "system.data.sqlclient.sqlexeption' occured in system.data.dll**********************


With cboItemNumber
.DataSource = dt
.DisplayMember = "ItemNumber"
End With

You call da.Fill on a dataset, not a data table.

VB Code:

da.Fill(MyDS, "auto)

Still getting the same error. I am will to pay someone for information that gets this running!!!

Put the code in a try/catch block to catch the exception message. You set the cmdText twice, once you don't bracket auto, once you don't. I know you bracket keywords in Access if you use them for table or field names, but don't know about SQL Server.

You are not specifying the location of the SQL database.

Your connection should look something like this:

VB Code:

Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString = "Data Source=(local);" & _
                            "Initial Catalog=myDatabaseName;" & _
                            "Integrated Security=SSPI"
oSQLConn.Open()

I have been on here for a week now. It can't be done. I get an error on the SQLConn.Open() now. Anyone know why.

Dim mycommand As New SqlCommand
Dim myDS As DataSet = New DataSet
Dim Mydatagrid As New DataGrid
Dim da As New SqlDataAdapter

Dim SQLConn As SqlConnection = New SqlConnection
SQLConn.ConnectionString = "Data Source=(local);" & _
"Initial Catalog=JNASI.Justin.dbo;" & _
"Integrated Security=SSPI"
SQLConn.Open()



Dim cmdtext As String = "select * from [auto]"

da.SelectCommand = New SqlCommand(cmdtext, SQLConn)

Dim dt As New DataTable("Auto")
da.Fill(myDS)
With cboItemNumber
.DataSource = dt
.DisplayMember = "ItemNumber"
End With

Is this the name of your database? "JNASI.Justin.dbo" are you fully qualifying it, or does it really have the periods in it?

My program runs but thier is not data in my combo box!!!!

:(

Forget the datatable code. The da.Fill needs the table name as well. See my earlier post. Set the combobox datasource to the table in the dataset.

VB Code:

da.Fill(myDS, "Auto")
With cboItemNumber
   .DataSource = myDS.Tables("Auto")
   .DisplayMember = "ItemNumber
End With

YES---------

You are the man salvelinus!!!!!!!!!!
Thank you very very much.

No problem. Just don't ask for my help with multidimension arrays :sick:
