Dialog Filter (Standard 8)
7/8/2014
Review the use, syntax, options, and parameters for the Embedded Lockdown Manager (ELM) in Windows Embedded 8 Standard (Standard 8).
You can use Dialog Filter to control which pop-up windows and dialog boxes are displayed on the desktop.
Block Pop-up Windows
Each time a process creates or attempts to show a window, Dialog Filter examines the following properties of the new window:
- The title of the window
- The full pathname of the process that created the window
- The names and types of the top-level controls that belong to the window
Dialog Filter uses this information to identify any window or dialog box that matches entries in the blocked window list. Dialog Filter blocks matching windows by automatically performing a specified action on the window. You can configure what action Dialog Filter performs on the window based on the actions that are available to that window.
Dialog Filter examines only windows that have the desktop defined as the parent window. This prevents Dialog Filter from affecting lower-level windows, such as buttons, controls, and so on. Therefore, Dialog Filter can block only windows that are displayed on the desktop.
Dialog Filter also ignores windows that are run as administrator.
Default Actions
You can configure Dialog Filter to, by default, either close or show any top-level window that is not blocked or part of a protected process.
If you do not define the default action, then Dialog Filter shows the window by default.
Protected Processes
You can configure Dialog Filter to indicate that a specific process is protected, so that any windows that belong to the process are shown, regardless of the configured default action. Windows that are specifically blocked are still blocked for protected processes.
Important
If you run ELM on your device and set the default action to close windows, you must first protect the mmc.exe process to allow ELM to continue to run.
Commands

You can select Show or Close as the default action. Show is selected by default.
