In Dialog base(MFC) application.
I Create second Dialog (I have Seperate Class for that Dialog) OnInitDialog() through Create(IDD_DLG, this);
So It becomes Modless Dialog.
Problem is that when Second Dialog(Child) when Display it is above of First Dialog(Parent).(as it should be b/c it is Current Focus)
I need when First Dialog(Parent) is Clicked(Focused) it becomes above of Second Dialog (Child).
and when Second Dialog (Child) is Clicked(Focused) it becomes above of First Dialog(Parent).

I try to use SetWindowPos(). But did not work. Like following
SetWindowPos(&CWnd::wndTopMost, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE);
::SetWindowPos(AfxGetApp()->GetMainWnd()->m_hWnd, HWND_TOPMOST, 0, 0, 0,0, SWP_NOMOVE | SWP_NOSIZE);

I also need to know which event occure when any Dialog get Focus (active). Even Clicked on the System Menu.
WM_PAINT
WM_SETFOCUS
GetFocus
I check all all these messages. They are not Confused | :confused:

Some code will be helped alot . . .

Thanks in advance.

You're creating the second as the child of the first. Try making the parent window NULL, or create both dialogs as children of a main dialog, which is not visible.

Use Spy++ to see all the messages sent when a dialog becomes active. I believe the one you want specifically is WM_CAPTURECHANGED

And How Can I do this. By SetParent(NULL). It does not work.

Thanks for WM_CAPTURECHANGED.
But still I my problem not solve.
I explain further what I need below.
As you know User can active Window By Clicking on the Title Bar of Dialog or My Clicking Dilog box itself(Client area). I need only Single event to monitor this.

Is there any material to use Spy++ (because I do not know effectively it).

Thanks.

You specify the parent in your Create call. I am using WM_CAPTURECHANGED to do exactly the same thing, and it works every way I can set the focus on my window.

Spy++ isn't hard, you just choose Find Window, select the Window and watch the messages come up.

The CDialog Create method takes two parameters:

BOOL Create( 
LPCTSTR lpszTemplateName, 
CWnd* pParentWnd = NULL );

Because the second defaults to NULL, it may not be getting set otherwise. I create modeless dialogs by putting the following in the constructor

if (Create(pParent, IDD)) ShowWindow(SW_SHOW)

Then I only need to create a dialog like this

CMyDialog dlg(this);

and the pointer to the window class I am in is passed as the parent, preserving the relationship I need to get the window of the child always above the parent.

Please Check my question.

I need that which Dialog is Active should be Front of Another.
I already checked this but this is not working.

In that case, the logical thing is to make both windows children of a third window, even if that third window is very small, or hidden.
