Hide Command Window using C# and VB.Net

Hi sir. I want to take a database backup using vb.net

I am using following code:

backupBtn.Text = MessageBox.Show("Want to back up your database?", "BACK-UP DATABASE!", MessageBoxButtons.YesNo)
        If backupBtn.Text = DialogResult.Yes Then
            backupBtn.Text = "Backup Database"
            Dim file2 As String
            sfd.Filter = "SQL Dump File (*.sql)|*.sql|All files (*.*)|*.*"
            sfd.FileName = "Database Backup " + DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".sql"
            If sfd.ShowDialog = DialogResult.OK Then
                file2 = sfd.FileName
                Dim myProcess As New Process()
                myProcess.StartInfo.FileName = "cmd.exe"
                myProcess.StartInfo.UseShellExecute = False
                myProcess.StartInfo.WorkingDirectory = "C:\xampp\mysql\bin"
                myProcess.StartInfo.RedirectStandardInput = True
                myProcess.StartInfo.RedirectStandardOutput = True
                myProcess.Start()
                Dim myStreamWriter As StreamWriter = myProcess.StandardInput
                Dim mystreamreader As StreamReader = myProcess.StandardOutput
                myStreamWriter.WriteLine("mysqldump --host=hostname --user=username --password=passwrd --silent databasename > """ + file2 + """")
                myStreamWriter.Close()
                myProcess.WaitForExit()
                myProcess.Close()
                MsgBox("Successfully created New backup", MsgBoxStyle.Information, "Backup")
            End If
        Else
            backupBtn.Text = "Backup Database"
        End If
