Trouble with pinned PropertyManager page

Hello everybody;

I work on an Add-in for solidworks,

I want to stay in the menu after validation


So i added a pin in the interface so that then user can choose whether to execute the function once,
or if he wishes to remain in the menu to execute it several times.

But i can't re-display the PropertyManager page after the add-in finishes its work.

This my code :

Private swDoc As ModelDoc2

Private sispmpage As PropertyManagerPage2

Public Sub AfterClose() Implements IPropertyManagerPage2Handler9.AfterClose

' Code to start the work of the add-in

  swDoc.ClearSelection2(True)

If pinned Then

sispmpage.Show2(0) ' <=== carshes here

sispmpage.Pinned = True

End If

End

End Sub


Thank you in advance
