When an activity displays a selection list of servers, databases, tables, or fields, the list normally contains only those servers (or other items) that exist and to which the user has access. Sometimes, it can be useful to include the names of nonexistent servers or databases in SampleMgtGUI.Config.xml ready for when these items become available. Use the showexistingonly attribute on the <SampleManagementGui> tag to control which items are included in these lists. For example:

When showexistingonly is set to true, selection lists includes only the names of the servers, databases, tables, or fields that are named in SampleMgtGUI.Config.xml and that the user can access.

When showexistingonly is set to false, selection lists include the names of all servers, databases, table, or fields named in the file, whether or not they exist, and the user can type an item name if it does not appear in the list. For example, if the user knows a server's IP address but not its name, the user can type in the IP address and the activity finds the corresponding server.
