Dialog-box behavior for a view ?

Environment: Windows 3.1, VC++ 1.51
I want to create a view derived-class that allow to create either :
* views with a normal behavior
* or views with a non-modal dialog-box behaviour, that is :
- they can't be desactivated, and no user's action is taken into
account out of the dialog box, until 'OK' or cancel has been chosen.
- the 2 buttons at their upper-right corner are not present.
I had the following ideas :
* override the OnMDIActivate function of the view's frame, and activate
the frame again when it is beeing desactivated. I tried that, where Fenetap
is the frame for the view, and "IsDialogSpecial" a function returning true if
the view is in a dialog-bow mode :
//////////////////
void Fenetap::OnMDIActivate(BOOL bActivate,CWnd* pActivateWnd,CWnd*
pDeactivateWnd)
{
if(!bActivate && IsDialogSpecial())
{
ShowWindow(SW_RESTORE); //for the case the view has been iconized
BringWindowToTop();
}
}
//////////////////
But it doesn't work : the two views (the newly activaded one and the
newly desactivated one seem to be both activated, and the newly activated
one is on the top). I guess their is something to send to the newly
activated view, but nothing I tried is working.
* lock the menu at the creation of the view, and de-lock it at the destruction
of the view (I don't know how to do it precisly at the moment).
*remove the 2 buttons at thee upper-right corner of the non-client area (I
couldn't
find how to do it in the help).
Many thanks for any help

There is a sample with source code in Per Ghosh's MFC page about creating a
modal window:
http://www.algonet.se/~hulken/dmfc.htm
File name is modal.zip.
It might be helpful to you.

You probably mean MODAL dialog-box behaviour, isn't it?
Try to set-up a mouse capture on the view like this:
void Fenetap::OnMDIActivate(BOOL bActivate,CWnd* pActivateWnd,CWnd*
pDeactivateWnd)
{
if(bActivate && IsDialogSpecial())
{
this->SetCapture();
}
}
This way, when your view will be activated ALL mouse input will go to
your view window
including attempts to click at menu, etc. All mouse events inside your
window will be handled as usual, other mouse messages will be simply
ignored.But you will have to catch
mouse clicks outside your application windows, to allow user switch
applications with mouse.
Also you will have to override OnSysCommand() to catch switching to
other MDI childs with
Ctrl-F6 Ctrl-Shift-F6, calling of the task list with Ctrl-Esc and maybe
something else.
Don't forget to call this->ReleaseCapture(); in your OK/Cancel buttons
handlers.

I don't know exactly, but you could try to call ::SetWindowLong() with
GWL_STYLE to
change the styles of the window on the fly. This is SDK function - not
part of the MFC.
*************************
Other possible solution is to create real DialogBox on top of your View
window.
You can create a dialog template, which looks exactly like you MDIFrame
window (w/o Min/Max buttons), than
at the moment when you need to enter 'DialogSpecial mode', get
coordinates of you MDI Child
and DoModal your dialog. In the OnInitDialog move it exactly over the
view's frame.

but I
hope this ideas will somehow help you.

Look at DLGPROP.CPP in MFC source directory, class CPropertySheet. It does all that you need (a window that works as modal/modeless dialog)
