ppDisp to display popup into form2

since we are creating an instance of explorer shell, is it possible to include something like:

Dim hwnd As Long
    hwnd = FindWindow(vbNullString, Me.Caption)
    SetWindowLong hwnd, -16, &H20000 Or &H10000 Or &H84C80080

in order to add a close button (that adds the two others but is for sake of example)
