Name:
    PropSheet

Description:
    Generates a property sheet window for remote administration.
	This object is used by the WinLoop object and expects an I/O
	object of name &quot;ClientIOObject&quot; to be in the
	configuration in case of network based remote administration.

<STRONG>+</STRONG> in the <IT>default</IT> indicates the field is mandatory<BR>

<H4>Description of Options</H4>
<H5>Host</H5>
The Host parameter is used to establish a remote interface connection to the
specified host. It must contain a valid hostname or IP address. A corresponding
Port parameter may exist. This parameter is mutual exclusive with the FileName
parameter.

<H5>Port</H5>
The Port parameter is optional used to establish a remote interface connection
using the specified port. It must contain a valid TCP port number.

<H5>AdminUser</H5>
The username is used to establish a remote interface connection. A corresponding
authentication setting (realm, user) must exist at the server. The interface
client determines the authentication type automatically. Supported authentication
types are &quot;Basic&quot; and &quot;Digest&quot; (recommended). If the AdminUser
is set but the AdminPassword is omitted, the Login Dialog is prefilled with the
value of AdminUser (recommended for Basic Authentication).

<H5>AdminPassword</H5>
The password is used to establish a remote interface connection. A corresponding
authentication setting (realm, user) must exist at the server. The interface
client determines the authentication type automatically. Supported authentication
types are &quot;Basic&quot; and &quot;Digest&quot; (recommended). If both AdminUser
and AdminPassword are set, the Login Dialog is omitted (not recommended for Basic
authentication). For Digest authentication the Admin password is the hexified MD5
hash of the username:password combination, which makes it nearly impossible to
compute the plain password from the stored password string.

<H5>FileName</H5>
The FileName is used to load the wanted configuration file locally. This parameter
is mutual exclusive with the Host parameter.

<H5>Title</H5>
The given string is used in the title bar of the PropSheet window.

<H5>PropertyPage</H5>
The PropertyPage directive may be repeated multiple times in order to fill the
PropSheet with the wanted property pages. You may simply comment out all pages,
which are unwanted for remote administration.

<H5>Options</H5>
Specifies options which effect the behaviour of the interface application.
<CENTER>
<TABLE BORDER=1>
<TH>Option
<TH>Meaning
<TR>
<TD>CreateDefault
<TD>Set appropriate default values in all PropertyPage objects.
Makes sense as an alternative to LoadFile option in order to
generate an initial configuration.

<TR>
<TD>LoadFile
<TD>Loads the configuration file dependant on the Host/FileName settings
either remotely or locally. Makes sense as an alternative to CreateDefault
option in order to edit an already existing configuration file.

</TABLE>
</CENTER>
Multiple options may be listed together by seperating them using the pipe
('|') character. Whitespace will be stripped from the option pattern.
Options are matched without regard to case sensitivity. Unknown options
will raise a configuration error. The Option directive may be repeated
multiple times.

Example:
	<PRE>
	&lt;Object&gt;
		Name PropSheet
		Class PropSheetClass
		Host localhost
		Port 80
		Title "Pi3Web Remote Administration"
		Options LoadFile
		PropertyPage GeneralPage
		PropertyPage PerformancePage
		PropertyPage HttpPage
		PropertyPage UsersPage
		PropertyPage MIMETypesPage
		PropertyPage MappingsPage
		PropertyPage LogFilePage
		PropertyPage IPVHostsPage
		PropertyPage NonIPVHostsPage
