I am making a dialog based application and I am trying to jump around from window to window using the following Idea:

create a new window. (modeless)
endcurrent window with this->EndDialog(0);

I am not really sure whats happening, but it seems somewhere windows are not being killed propertly. or something is using a lot more memory then it should. Basically I think it could be 2 things.

#1 Does EndDialog free any memory that it uses, or just hide the window ?
#2 Does pressing the X to close the window destroy it completely, or do I need to do "delete" on it ?

Don't know if it helps, but with a quick look it says everywhere EndDialog() is used for modal dialogs. Maybe you could try DestroyWindow() ?

On msdn it says the destroy window doesn't destroy the CWnd object.

I guess my problem is in the main design. If I create a window from a window,then destroy the first window, i've lost the pointer and can't delete the second one. I'm not sure how to get around that, cause its kind of a chain of windows, each one passing information to the next via CWnd derived class constructor.

Isn't the window an object then? If it is, you can get its address with the this pointer. So pass that address to the next window, or create some kind of a window creater function that deletes the former window and creates a new one. Maybe?

err, yes of course, didn't think of that, so simple

Ill try that, thanks a lot !
