[win32]
icon_visible=0 or 1
If 1, an icon (shown in the system tray on Windows 95/NT4 or later from 4.520/4,616), is created for the SRVW32 program even when it is run as a service. The icon will not be visible unless the service can interact with the desktop.
When DP4 is run as a service you can prevent the icon being created by setting icon_visible=0 in the [win32] section of the DP4 configuration file. The default for icon_visible is 1 rather than 0, from 4.616/4.520, except on NT 3.51
From 4.620 (5) (issued 17 Feb 2003) icon_visible=0 also works when srvw32.exe or srvwce.exe is run as an application.
