Close sub-dialogs when main dialog is closed

[ssimop]

Suppose that a dialog (main dialog) launches several several sub-dialogs through relevant functions. Is it possible to assign a class to these sub-dialogs with the purpose to close them all-together when the main dialog is closed?

Many thanks in advance.

Main dialog:

ARRAY(int)- t_a
...
t_a[]=newDialogHandle
t_a[]=newDialogHandle
...
case WM_DESTROY
for(i 0 t_a.len) if(IsWindow(t_a[i])) clo t_a[i]

Is it possible to assign a class

It is possible to create dialogs with class name other than #32770. You can specify it in dialog definition, like "MyDialogClass" in this example. Note that Dialog Editor removes it when saving. Little tested.

Function Dialog166

Code:

Copy      Help

\Dialog_Editor

__RegisterWindowClass+ __MyDialogClass; if(!__MyDialogClass.atom) __MyDialogClass.Superclass("#32770" "MyDialogClass" &DefDlgProcW)

str dd=
;BEGIN DIALOG
;1 "MyDialogClass" 0x90C80AC8 0x0 0 0 224 136 "Dialog"
;1 Button 0x54030001 0x4 116 116 48 14 "OK"
;2 Button 0x54030000 0x4 168 116 48 14 "Cancel"
;END DIALOG
;DIALOG EDITOR: "" 0 "*" "" "" ""

if(!ShowDialog(dd &sub.DlgProc 0)) ret


#sub DlgProc
function# hDlg message wParam lParam

sel message
,case WM_INITDIALOG
,case WM_DESTROY
,case WM_COMMAND goto messages2
ret
;messages2
sel wParam
,case IDOK
,case IDCANCEL
ret 1

Excellent solutions. Thank you very much indeed.

Dear Gintaras,

I understand that apart the two methods proposed by you above, it still exists the method proposed also by you in the above link, namely :

I would appreciate it if you could kindly comment on the two methods (ARRAY(int) ... against SetProp . Do you think there exist advantages and disandvantages? I have tested them both and they work satisfactorily.

Many thanks in advance.

Both methods are good. In some cases SetProp/GetProp/RemoveProp is easier, in some cases array.
