I use Create()& SetWindowPos functions to put the new dialog at the bottom of this button.
Firstly, I've tried to use OnKillFocus to check when the dialog lost focus but I always get WM_KILLFOCUS message immediately after SetWindowPos function. So the dialog disappear immediately after appear.

I've tried to catch WM_ACTIVATE

void CYourDlg::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized) 
{
		
	if ((WM_INACTIVE == nState ) && (pWndOther == FromHandle(m_hWnd))
        { 
            // Here dismiss your dialog, for instance: CDialog::OnClose();
