Facility Control

I am looking to use Dashboard code to look at a directory and read all the filenames in the directory. The idea is to have a folder of images that can be dropped in, and Dashboard would be able to read each filename to then send back to XPression as a material for a rotating slideshow. 

I know I can verify a specific file using "ogscript.getFile(filepath)" but I am looking for a way to not just verify a specific file, but to look at the folder itself and give me back what files are in there.

Any help would be appreciated.

Thanks!

Hi Jake

Here is an example panel that does this.  You're on the right track with getFile - argument passed-in can be either a file or a directory.  To get an array of the Files inside of a directory, call getFile with the directory path and use list() on the returned object.  Here is an example panel that exercises the feature:

<abs contexttype="opengear">   <meta>      <params>         <param access="1" maxlength="0" name="Starting Directory" oid="Starting_Directory" type="STRING" value="C:\" widget="text"/>         <param access="1" constrainttype="STRING_CHOICE" maxlength="0" name="File List" oid="File_List" type="STRING" value=" " widget="combo">            <constraint/>         </param>         <param access="1" maxlength="0" name="File Extension" oid="extension" type="STRING" value="*" widget="default"/>      </params>   </meta>   <label height="40" left="20" name="Starting Directory: " style="txt-align:east" top="20" width="160"/>   <param expand="true" height="40" left="180" oid="Starting_Directory" top="20" width="380"/>   <label height="40" left="20" name="File Extension: " style="txt-align:east;" top="70" width="160"/>   <param expand="true" height="40" left="180" oid="extension" showlabel="false" top="70" width="160"/>   <label height="40" left="20" name="File List: " style="txt-align:east" top="120" width="160"/>   <param expand="true" height="40" left="180" oid="File_List" showlabel="false" top="120" width="380"/>   <button buttontype="push" height="40" left="580" name="Load" top="20" width="100">      <task tasktype="ogscript">var file = ogscript.getFile(params.getValue('Starting_Directory', 0));if (file != null &amp;&amp; file.exists() &amp;&amp; file.isDirectory()){   var filter = params.getValue('extension', 0).trim();    //this would be optional   var list = file.list();   var filteredList = [];   for (var i = 0; i &lt; list.length; i++)   {      if (filter == '*' || list[i].toLowerCase().endsWith(filter))  //Check the filter      {         filteredList.push(list[i]);      }   }   if (filteredList.length == 0)  //Put a blank if we have no files that match the filter   {      filteredList.push("");   }   var constraint = params.createStringChoiceConstraint(filteredList);   if (constraint != null)   {      params.replaceConstraint('File_List', constraint);   }}</task>   </button></abs>

The relevant snippet is this:

var file = ogscript.getFile(params.getValue('Starting_Directory', 0));if (file != null && file.exists() && file.isDirectory()){   var filter = params.getValue('extension', 0).trim();    //this would be optional   var list = file.list();...
