Sorry For my Bad Details, Please Help Thanks

If you really want to do that, then i would suggest to use a backgroundworker.
Before starting this worker, you disable all controls that you need to disable and display the wait image.
In the dowork event of that worker you do your sql query.
In the work_complete event of this worker you then enable all your fields again and hide the image.

Example:

Imports System.ComponentModel

Public Class LoginBGW

	Private Sub ToogleControls(enabled As Boolean)
		txtLogin.Enabled = enabled
		Button1.Enabled = enabled
		PictureBox1.Visible = Not enabled 'remember to set the visible property on the designer to false, else it will show up at the first time.
	End Sub

	Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
		ToogleControls(False)
		Dim BGW As New BackgroundWorker
		With BGW
			.WorkerSupportsCancellation = False
			AddHandler .DoWork, AddressOf BGW_DoWork
			AddHandler .RunWorkerCompleted, AddressOf BGW_Completed
			.RunWorkerAsync()
		End With
	End Sub

	Private Sub BGW_DoWork(sender As Object, e As DoWorkEventArgs)
		'do your login stuff here
		'once it is completed the "BGW_Completed" get raised

		'for testing
		System.Threading.Thread.Sleep(3000)
	End Sub

	Private Sub BGW_Completed(sender As Object, e As RunWorkerCompletedEventArgs)
		ToogleControls(True)
	End Sub

End Class
