<concept id="GUID-CA35A708-C6D9-51D7-873B-A79606FFAF66" xml:lang="en"><title>How

to search for files with TFindFile</title><shortdesc>This topic provides an example on how to search for files with

TFindFile.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The following example accumulates a list of all the files on any drive

which are in a particular directory and which match a name with wildcards,

for example, all files matching <filepath>\resources\fonts\*.gdr</filepath>. </p>

<p>To start a search, use <codeph>TFindFile::FindWildByDir()</codeph>. You

can then call <codeph>TFindFile::FindWild()</codeph> to perform the same search

on another drive. </p>

<p>To retrieve the fully qualified path of the matching files, class <codeph>TParse</codeph> is

used to combine the filename with the drive letter and directory which contains

the file. The example works as follows: </p>

<ol id="GUID-E589950F-603A-5BB3-9387-06D1B2CE2E4B">

<li id="GUID-A748895E-D312-505C-A2D7-3C35952F7913"><p>Construct a <codeph>TFindFile</codeph> object. </p> </li>

<li id="GUID-A6DE36F9-033A-534B-A27D-A3B8FC50A8D5"><p>Use <codeph>FindWildByDir()</codeph> to

start the search for matching files. There is considerable flexibility in

the handling of <codeph>aWildName</codeph> and <codeph>aScanDir</codeph>,

but the simplest and most common case is where <codeph>aWildName</codeph> is

the filename and extension (for example, <filepath>*.gdr</filepath>) and <codeph>aScanDir</codeph> is

the directory name, without a drive letter, but including a trailing directory

separator (for example, <filepath>\resources\fonts\</filepath>). </p> </li>

<li id="GUID-44EE24DB-880F-52A4-85E1-02C575CC6B9F"><p>The list of matching

files is returned in a <codeph>CDir</codeph> object, which is implemented

as an array. <codeph>Count()</codeph> retrieves the number of items in the

list. </p> </li>

<li id="GUID-FE931EA6-0AB0-5D5C-88ED-7E4F506DDE60"><p>Use <codeph>file_finder.File()</codeph> to

retrieve the drive and path of the folder containing the files in the <codeph>CDir</codeph>,

(for example <filepath>Z:\resources\fonts\</filepath>). </p> </li>

<li id="GUID-67ACA73A-CDDE-5C95-8B31-4D421BE4D95D"><p>Use <codeph>TParse::Set()</codeph> to

combine the file name and path into a full filename. </p> </li>

<li id="GUID-B9EEB198-264B-5A82-869D-329077498849"><p>Use <codeph>TFindFile::FindWild()</codeph> to

continue the search on the next drive in the search sequence. </p> </li>

</ol>
