I'm trying to develop a windows application in which I want to have an option to copy the data from an excel file to the sql database table.

I copied a code from the internet but I'm getting some errors in it.

This is my code:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
        Dim ExcelConnection As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=example.xls;Extended Properties=""Excel 12.0 Xml;HDR=Yes""")

       <big>Dim expr As String = "SELECT * FROM [Sheet1$]" </big>  
      Dim objCmdSelect As OleDbCommand = New OleDbCommand(expr, ExcelConnection)
        Dim objDR As OleDbDataReader

        Dim SQLconn As New SqlConnection()
        Dim ConnString As String = "Data Source=ASPIRE5741G-PC;Initial Catalog=exceltosql;Integrated Security=True"
        SQLconn.ConnectionString = ConnString

        Using bulkCopy As SqlBulkCopy = New SqlBulkCopy(SQLconn)
            bulkCopy.DestinationTableName = "emp"

                objDR = objCmdSelect.ExecuteReader

            Catch ex As Exception
            End Try
        End Using

    End Sub

the error is in the line
Dim expr As String = &quot;SELECT * FROM [Sheet1$]&quot;

the error message is:
The Microsoft Jet database engine could not find the object 'Sheet1$'.  Make sure the object exists and that you spell its name and the path name correctly.

But the Excel sheet name is the same, and I tried almost all the options available in the google search results.

Please help.

I am not able to continue my project without this .

Edited for Grammar.

Take a look at this part of code:
Data Source=example.xls

So i ask: where is the path to example.xls file?
Data Source=C:\Folder1\Folder2\example.xls

Which version of Excel do you have?

Try to optimize your code.
1. use Try...Catch ex... Finally... End Try block to catch errors
2. ExcelConnection is never closed

See warnings about using SQLBulkCopy:[^][^]

Good Call.
Hi jasminkp

You can use this function to get records form excel it is tested and working.
Public Shared Function GetRecordsFromExcelSheet(ByVal strFilePath As String) As DataTable

                Dim strConnectionString As String
                strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; " & _
                                                "Data source='" & strFilePath & "'; " & "Extended Properties=Excel 8.0;"

                Dim outputTable = Nothing
                Using conn As New OleDb.OleDbConnection(strConnectionString)
                    Dim schemaTable As DataTable = conn.GetOleDbSchemaTable(OleDb.OleDbSchemaGuid.Tables, New Object() {Nothing, Nothing, Nothing, "TABLE"})
                    Dim sheet As String = schemaTable.Rows(0)("TABLE_NAME").ToString()
                    Dim cmd As New OleDb.OleDbCommand("SELECT * FROM [" & sheet & "]", conn)
                    cmd.CommandType = CommandType.Text
                    Dim output As New DataSet()
                    outputTable = New DataTable(sheet)
                    Dim objOleDbDataAdapter As New OleDb.OleDbDataAdapter(cmd)
                End Using
                Return outputTable
            Catch ex As Exception
                Throw ex
            End Try
        End Function

Thanks for your reply...

I don't have any name for the table in the Excel file. And the file is there in the project folder itself.

For the first time am working with a windows applicaton..

So if possible give me the complete code to copy the contents to the sql table also.

Pls help...........
