Hi,
Try the code snippets below:

VB

Try

           Dim MyConnection As System.Data.OleDb.OleDbConnection
           Dim myCommand As New System.Data.OleDb.OleDbCommand
           Dim sql As String

           MyConnection = New System.Data.OleDb.OleDbConnection _
           ("provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + _
           "'c:\testfile.xls';Extended Properties=Excel 8.0;")

           MyConnection.Open()
           myCommand.Connection = MyConnection
           sql = "Insert into [Sheet1$] (id,name) values('5','e')"
           myCommand.CommandText = sql
           myCommand.ExecuteNonQuery()
           MyConnection.Close()

       Catch ex As Exception
           MsgBox(ex.ToString)
       End Try

       MsgBox("Row Added ")

Hi
Thats what I have been trying but I need to be able to add at a specific location such as A22 or B15. The SQL in the example above is using field names. Do you have an example of using column and row names instead?

Thanks

Solution 4

If you want to modify a cells value you can try something like:

SQL

UPDATE [Sheet1$A22:A22] SET F1='And the data goes here';

Remember to set HDR=NO to your connection string in order not to use a header row.
