Hi all,
I am developing Dialog based application.This application
contains so many no. of dialogs. So i need to close all open dialogs
when i click the button in one dialog like named "Close All". I tried
with OnCancel and OnOK both this will close only one dialog of which i
called from. So any one can help me.

Thanks in advance,
SaranG.

Hi SaranG,
nomally I use for multiple dialoges the classes CPropertySheet /
CPropertyPage. I don't know if you do so. But I will explain you the way to
close the pages on the following sample.

CPropertySheet = parent
|
+-> CPropertyPage -> CPropertySheet = parent
| : |
+-> CPropertyPage .. +-> CPropertyPage ..
| : | :
+-> CPropertyPage .. +-> CPropertyPage ..
| : | :

/*==================================================
OnOK ( CPropertyPage )
==================================================*/
void CppXXXX::OnOK()
{
CPropertyPage::OnOK();
// On button OK send a close message to the parent
// ( CPropertySheet ) and let him close the childs
CWnd* pParentWnd = GetParent();
pParentWnd->SendMessage( WM_CLOSE, 0, (LPARAM)0 );
}

/*==================================================
OnOK ( CPropertySheet )
==================================================*/
void CpshXXXX::OnClose()
{
WORD i;
if( pDaten->m_pPropPages[i]->m_hWnd != NULL )
{ // send a close message to the child ( CPropertyPage )
for( i = 0; i < 3; i++ )
{ CWnd* pChildWnd = FromHandle( pDaten->m_pPropPages[i]->m_hWnd );
pChildWnd->SendMessage( WM_CLOSE, 0, (LPARAM)0 ); }
}
CPropertySheet::OnClose();
}

Continue this way until all your dialogues are closed. Also implement the
close for the cancel button.

Maybe it will help you.

}
}
}
CPropertySheet::OnClose();
}

Aside from keeping track of open dialogs on your own and just sending
WM_CLOSE message to each (using PostMessage) you could use something like:

http://msdn.microsoft.com/en-us/library/ms633494(VS.85).aspx

To call a function for all open windows and just send the message to the
dialog types (or whatever types you want to close).

Are they modal or modeless?

For modal it is trivial. You click the "Close All" button on the most recent modal dialog
and then you explicitly call EndDialog with a code that is not expected (e.g., IDABORT),
and the caller interprets that to be a request to close itself with the same code, etc.

For modeless, I tend to do something like SendMessageToDescendants from the mainframe with
a user-defined message such as UWM_CLOSE_ALL_DIALOGS and every modeless dialog that
receives it closes itself.

Hi,
Thanks for all who enlighten me up. And i made that closing of
all open dialog with some flag variables usage.
And tried with the WM_CLOSE message.
Once again,
Thanks
SaranG.
