	Starts message logging and displays the message stream. This control is available only when a Messages window is the active window. For more information, see How to: Start and Stop the Message Log Display.
	Stops message logging and the display of the message stream. This control is available only when a Messages window is the active window. For more information, see How to: Start and Stop the Message Log Display.

This control (and the related menu command) is available only when there is a valid search result that is not unique. For example, when you use a window handle as the search criterion in the window tree, it produces unique results because there is only one window in the window tree that has that handle; in this instance, Find Next is not available.

This control (and the related menu command) is available only when there is a valid search result that is not unique. For example, when you use a window handle as the search criterion in the window tree, it produces unique results because there is only one window in the window tree that has that handle; in this instance, Find Previous is not available.
