Umapathi K asked:
self form should close

This could not be if done if processes are not interrelated to the program.
Try this:

VB

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If File.Exists("c:\hi.txt") Then
            Me.Hide()
            successform.Show()
        Else
            Me.Show()
            successform.Hide()'You missed this.
        End If
    End Sub

You missed to hide the successform.

You are checking File.Exists("c:\hi.txt"). Is checking whether the file is there in your c drive or not. Use System.Diagnostics.Process to check the process. Then check your file whether it is opened in the current process or not. :)

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If File.Exists("C:\WINDOWS\tscc.txt") Then
Me.Hide() 'it should get hide
successform.Show()
Else
Me.Show()
successform.Hide()
End If
End Sub
