Closing childwindow close also mainwindow

[rommi]

Hi all!

I have created a Mainwindow with a lot of childwindows in it. The quantity of ChildNow is dynamic cause i want to close or add Childwindwos during the Runtime. Every Childwindow has no titelbar but it has a little button to close the childwindow. Now my problem is that if i close one of the existing Childwindws then the Mainwindow is also closing. How can i avoid it? Here a quick description how my code works:

HWND *Childwin = new HWND(100); // dynamic array for the children
HWND mainhwnd; // mainwindow

Winmain (...)
{
...

// create mainwindow
mainhwnd = ....

// create some childs
for(i=0;i<10;i++)
{
Childwin[i] = ....
}

...

}


Callback(...)
{
...
	WM_COMMAND
	...
		default
		if a certain quit-Childbutton is pressed
		DestroyWindow(Child[i]);

	WM_DESTROY
		PostQuitMessage(0);

	WM_PAINT
		BitBlt...
		draw Child and Main...

	WM_TIMER
	...
...
}

I guess always if i want to close a childwindow a WM_COMMAND message is generated but also a WM_DESTROY message what also close the mainwindow, but how can i avoid this or anybody has a better concept to close childwindows inside mainwindow?

My second question is that i want add childwindows during the runtime. On a certain event on my desktop a new childwindow should created and appear in the mainwindow as the other childrens. Does anybody has a starting clue how i can realize?

Many thanks in advance, best regards rommi
