Class(Child window )destructor not getting called

Question

I have created a window which has a toolbar with some icons, and I launch one more window clicking on the available icon from the main window.

First window is created using CreateWindowEx method. the one I click using an icon is created using dialog resource. So without closing dialog, I directly close the main window. I see that dialog window is not getting closed. When I debug, control does not come to destructor of second window.

When I close them individually (i.e dialog first) and then main window next,then everything is fine.

Please help,that what might be missing when I close the main window.

I mean class desctructor is not getting called.

Handle your main window's message WM_CLOSE and check, whether the dialog window is open or not. If dialog window is open, just close it using the handle you got returned while loading it from resources.
