    <p>I created a VB.Net application that will read from excel file and put the data into a table. I used an excel sheet which has 3 columns and 65000 rows. Before starts reading the excel my machine's CPU Usage is around 15%, but during reading the CPU Usage jumps upto 95%. I don't know why it is happening? Can someone help me in this issue? The following is the code i'd written:</p> <pre><code>Private Sub readFromExcel(ByVal fileName As String, ByVal sheetName As String) Dim connString As String = "data source=XE; user=test; password=test" Dim con As New OracleConnection(connString) Dim str1 As String Dim str2 As String Dim str3 As String Dim xlApp As Excel.Application Dim xlWorkBook As Excel.Workbook Dim xlWorkSheet As Excel.Worksheet xlApp = New Excel.ApplicationClass xlWorkBook = xlApp.Workbooks.Open(fileName) xlWorkSheet = xlWorkBook.Worksheets(sheetName) Dim x As Integer Dim y As Integer Dim i As Integer x = xlWorkSheet.Rows.Count() y = xlWorkSheet.Columns.Count() Try For i = 1 To x - 1 'MsgBox(xlWorkSheet.Cells(i, 0).value) str1 = xlWorkSheet.Cells(i, 1).value str2 = xlWorkSheet.Cells(i, 2).value str3 = xlWorkSheet.Cells(i, 3).value insertData() Next Catch ex As Exception MsgBox(ex.Message()) Finally con.Close() xlWorkBook.Close() End Try End Sub Private Sub insertData() Dim str As String str = "insert into test_import values('" + str1 + "'," + str2 + "," + str3 + ")" Dim cmd As New OracleCommand() cmd.CommandText = str cmd.Connection = con cmd.ExecuteNonQuery() End Sub </code></pre> <p>thx in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
