== FieldNumbers Property ==

== Applies To ==
* [[FileMan_Delphi_Components/TFMFinder|TFMFinder]]
* [[FileMan_Delphi_Components/TFMGets|TFMGets]]
* [[FileMan_Delphi_Components/TFMLister|TFMLister]]

== Declaration ==

<code> property FieldNumbers: TStrings; </code>

== Description ==

This is a list of field numbers representing the fields to be retrieved by the data access component.

The default value of this property is a single array item set to ".01". Set each item in this '''TStrings''' array to a field number that should be retrieved. When a server call is made, all items in the array are concatenated into a single Fields parameter to pass to the data access component's underlying DBS call.

You can set array items in the '''FieldNumbers''' array in the following formats:
<table>
<tr><th>Item Format Applies To Example
<tr><td>Individual field</td><td>All</td><td>.01</td></tr>
<tr><td>DR-style list</td><td>All</td><td>.01;2;3;5</td></tr>
<tr><td>DR-style range</td><td>[[FileMan_Delphi_Components/TFMGets|TFMGets]] only</td><td>.01:5</td></tr>
</table>
For the [[FileMan_Delphi_Components/TFMGets|TFMGets]] component, to set this property at run-time, use the [[FileMan_Delphi_Components/TFMGets_AddField|AddField]] and [[FileMan_Delphi_Components/TFMGets_RemoveField|RemoveField]] methods. For [[FileMan_Delphi_Components/TFMFinder|TFMFinder]] and [[FileMan_Delphi_Components/TFMLister|TFMLister]] components, use '''TStrings''' methods to set this property at run-time.
