Hi,

How do I export a mysql query result to an Excel sheet in Vb.net.This is my code until now:
Imports MySql.Data.MySqlClient
Imports System.Data
 
Public Class FrmMain
    Dim conn As MySqlConnection
    Dim myCommand As New MySqlCommand()
    Dim myAdapter As New MySqlDataAdapter()
    Dim myData As New DataTable()
    Dim SQL As String
 
    Private myConnString As String
 
    Public WriteOnly Property connectionString() As String
        Set(ByVal value As String)
            myConnString = value
            conn = New MySqlConnection()
            conn.ConnectionString = myConnString
 
            Try
                conn.Open()
            Catch myerror As MySqlException
                MessageBox.Show("Error Connecting to Database: " & myerror.Message)
            End Try
        End Set
    End Property
 
    Private Sub cmdRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRefresh.Click
        Dim conn As New MySqlConnection()
        Dim myCommand As New MySqlCommand()
        Dim myAdapter As New MySqlDataAdapter()
        Dim myData As New DataTable()
        Dim SQL As String
        Dim Hash5 As XmlWriteMode
 
 
        SQL = "SELECT filereputationsummary.fileMD5 FROM filereputationsummary" _
                & " WHERE `numSubmissions`>100000" _
                & " Order by `numSubmissions`;"
        'conn = New MySqlConnection()
        conn.ConnectionString = myConnString
 
        Try
            conn.Open()
 
            Try
                myCommand.Connection = conn
                myCommand.CommandText = SQL
 
                myAdapter.SelectCommand = myCommand
                myAdapter.Fill(myData)
 
 
                DGVReport.DataSource = myData
                DGVReport.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells
                'myData.WriteXml(Hash5)
 
                Me.Show()
 
            Catch myerror As MySqlException
                MsgBox("There was an error reading from the database: " & myerror.Message)
            End Try
        Catch myerror As MySqlException
            MessageBox.Show("Error connecting to the database: " & myerror.Message)
        Finally
            If conn.State <> ConnectionState.Closed Then conn.Close()
        End Try
    End Sub
 
End Class
