Use background worker.

Create a form and place Label,progress bar if you want. Set Style property of progressbar as marquee since value for progress bar may not be fixed.

and use this kind of code structure:

Imports System.ComponentModel
Public Class Form1
Dim WithEvents myWorker As BackgroundWorker

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
myWorker = New BackgroundWorker
myWorker.RunWorkerAsync()
End Sub

Private Sub doWork(ByVal sender As Object, ByVal e As EventArgs) Handles myWorker.DoWork
showForm()
'load datagrid
End Sub
Private Sub showForm()
'Dim tempForm as New yourLoadingForm
'tempForm.ShowDialog

End Sub
End Class

certainly it should.

you can also have more than 1 background workers if you really need them.
Or you can use Threading. Background worker is just a different class that provides some more features than threading, which can be implemented while using plain threading anyway.
