I am wrting an app using MFC in Microsoft Visual C++
My system is connected to an UPS unit sending a command to close windows when a power failure is detected (The DestroyWindow function is automatically activated).
It is working well when my main view is active.
But if a modal dialog box is open the system crashes.
I suppose that all ressources are not closed properly.
My question is :How from the main DestroyWindow function
can i close all opened modal dialog boxes ?
