Parameter passing issue from Non-FPM Application to FPM Application

Hi,

I have Non-FPM application and on click of button I want to navigate to another application which is OIF. Problem is I am unable to pass parameter as HandleDefault method of Main Window in FPM application is not called, Instead it calls WDDOINIT method of View in FPM application directly.

Please help on How to pass parameter from Non-FPM to FPM application.
