HOOK WH_MOUSE_LL，根据鼠标点击的位置判断是否在对话框的区域内

HWND g_hWnd = NULL;
HHOOK hOldHook = NULL;
LRESULT CALLBACK LowLevelMouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
	if((HC_ACTION == nCode) && (WM_LBUTTONDOWN ==wParam))
	{
		CPoint pt;
		CRect rc;
		GetCursorPos(&pt);
		GetWindowRect(g_hWnd, &rc);

		if(!rc.PtInRect(pt))
		{
			PostMessage(g_hWnd, WM_CLOSE, 0, 0);
		}
	}
	return CallNextHookEx(hOldHook, nCode, wParam, lParam);
}

void CXXXDlg::OnOK() 
{
	g_hWnd = GetSafeHwnd();

	hOldHook = (HHOOK)SetWindowsHookEx(WH_MOUSE_LL, LowLevelMouseProc, AfxGetInstanceHandle(), 0);
}

用spy+看一下窗口失去焦点时的消息（具体名字我不记得了）根据这个消息和退出模态对话框。
