Imports System.Data
Imports System.Data.SqlClient
Public Class frmMain
    Dim objConn As SqlConnection
    Dim objCmd As SqlCommand

 Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim strConnString As String
        strConnString = "Server=localhost;Uid=sa;PASSWORD=024274628;database=GAFBiz;Max Pool Size=400;Connect Timeout=600;"
        objConn = New SqlConnection(strConnString)
        objConn.Open()
        If objConn.State = ConnectionState.Open Then

            MessageBox.Show("SQL Server Connected")

        Else

            MessageBox.Show("SQL Server Connect Failed")

        End If

        Me.WindowState = FormWindowState.Maximized
    End Sub
