while creating the dsn there is an error occuring.
Attempted to read or write memory . This is often an indication that other memory is corrupt.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CreateAccessDSN("Nilish", "d:\Database\dbase.mdb")
End Sub
Public Function CreateDSN(ByVal Driver As String, ByVal Attributes As _
String) As Boolean
CreateDSN = SQLConfigDataSource(0&, ODBC_ADD_SYS_DSN, _
Driver, Attributes)
End Function
Public Function CreateAccessDSN(ByVal DSNName As String, _
ByVal DatabaseFullPath As String) As Boolean
Dim sAttributes As String
If Dir(DatabaseFullPath) = "" Then Exit Function
sAttributes = "DSN=" & DSNName & " "
sAttributes += "DBQ=" & DatabaseFullPath & " "
CreateAccessDSN = CreateDSN("Microsoft Access Driver (*.mdb)", _
sAttributes)
End Function

Why are you even using a DSN in the first place? There's no reason for it anymore...

Hi!
I am facing some problem while reading from CSV file and updating database from the data available in csv file. My problem is that CSV files are too large having atleast 5000 rows and while updating database for each row I need to query database for atleast four times. It means I have to query the database for atleast 200,000 for a single file. This is retarding my application's processing speed and increasing load on machine as well as on database server. Please suggest me how to cope up with this problem?
Thanks and Regards,
Virendra

You should be using DTS (Data Transformation Services) for this, it would drastically bring down the time you would be spending in importing this data. The package can contain conditions and code to suit the business logic.
Have a look at these articles to get an idea about dts:
DTS VB .NET[^], DTS Export[^], Dynamic Creation of DTS Package[^]

What have you changed that made it stop working?
The TextChanged event is a server event, so it can only fire during a postback.
When you press enter, it can either be caught by the focused control (if it is a textarea, a select or a button) or by the form. If the form catches it, it will act as if the first button in the form was clicked.

Hi..Happy to here from you again .
The only change I made it was putting the asp:textbox in a <DIV> instead of a <table><tr><td>.
I observed when I press enter in the textbox I hear a sound(one of the windows usual sounds).
I am too late but i will never give up

Select Datagridview. Now Click on smart tag which is on top Right corner then select Option "Edit Column".Now select the column from selected column list which is of combo box type. Now Select Property Items(collection Type) and Press the associated button button.

I'm not sure if this will answer your question, but the following code segment first creates a DataTable containing values for my combo box, then creates a column that is inserted into a datagrid.
Dim typeDesc As New DataTable
Dim dr As DataRow
typeDesc.Columns.Add("Indx", Type.GetType("System.Int32")) '0
typeDesc.Columns.Add("Desc", Type.GetType("System.String")) '1
dr = typeDesc.NewRow()
dr(0) = 0 : dr(1) = "Rural"
typeDesc.Rows.Add(dr)
dr = typeDesc.NewRow()
dr(0) = 1 : dr(1) = "Suburban"
typeDesc.Rows.Add(dr)
dr = typeDesc.NewRow()
dr(0) = 2 : dr(1) = "Urban"
typeDesc.Rows.Add(dr) ' datatable giving values type
newCol = New DataGridViewComboBoxColumn
newCol.Width = 90
newCol.HeaderText = "Parcel Type"
newCol.DataSource = typeDesc
newCol.ValueMember = "Indx"
newCol.DisplayMember = "Desc"
dgvTasks.Columns.Insert(2, newCol)
The dgvTasks is the name of the datagrid in which the combo will appear.

There's not enough information in your question to answer it. What do you want to do with Outlook?
