Hi Maileen
I hope you mean single form instance, and not single application instance...
Code for Form1 class:
1. Modify the public constructor so it is private
2. Add a shared member of type Form1
3. Add a public shared function that returns Form1
To get the form call:
Dim f As Form1 = Form1.GetForm()
HTH

Private Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
Private Shared mForm1 As Form1 = Nothing
Public Shared Function GetForm() As Form1
If mForm1 Is Nothing Then
mForm1 = New Form1
End If
Return mForm1
End Function
