Open a file using wildcards

Thank you both very much for taking the time to help a newbie. 

Chuck, I really appreciate the script you sent. It worked perfectly. You are very kind. Much appreciated!

Thanks for the guidance.  With the abundance of information on this forum in Javascript, I gave up on VBA and switched to Javascript.  I'm still wrapping my head around the syntax, but managed to hack my way through and pieced together a script that works for my project. 

However I’m still struggling with looping through files in a directory. 

Currently my script, opens a folder, locates the appropriate files and processes them.
(folder titled “Output_Files” has the required png files. The script successfully processes the appropriate png files.)

What I need it to do is open a folder, open the first subfolder, locate the appropriate png files and process.  Move to the next subfolder, locate the appropriate png files and process. Proceed until all the files within all the subfolder have been processed. (folder located at “C:\Rendermation\Renders” has subfolders with random names like “View_ItemNumber_1234” and within this subfolder are the required pngs to process.)

Hope this makes sense.

Anybody have ideas?  Thanks so much in advance.

BTW, how to i iplace code in a thread and have it view like code (see Chuck Uebeles example above)? 

cTID = function(s) { return app.charIDToTypeID(s); };

sTID = function(s) { return app.stringIDToTypeID(s); };

var srcFolder = Folder( Folder.desktop + '/Output_Files' ); // Make sure this is correct for your hard coded path???

//scrFolder defined as the source folder in code 

//Search folder for VIEW Bluestone & CenterGem png 

var str1 = '*bluestone**CenterGem.png*'  ;

var fileList = srcFolder.getFiles(str1); 

for ( var i = 0; i < fileList.length; i++ )

// Open VIEW Bluestone & CenterGem png

app.open( fileList ) ;

//Search folder for VIEW Bluestone & Shadow png 

var str2 = '*bluestone**Shadow.png*'  ;

var fileList = srcFolder.getFiles(str2);

for ( var i = 0; i < fileList.length; i++ ) 

// Open VIEW Bluestone & Shadow png Copy Then Close and Paste In Place in original file

file = app.open( fileList ) ;

//prepare active document

   activeFile= app.activeDocument;

//  activeFile.resizeImage(width,height); //resize image into given size i.e 640x480

   activeFile.selection.selectAll();

   activeFile.selection.copy(); //copy image into clipboard

   activeFile.close(SaveOptions.DONOTSAVECHANGES); //close image without saving changes

  //activeate function to paste in place

  pasteInPlace();

  createSmartObject(app.activeDocument.activeLayer);

app.load(File('~/Desktop/TrimGem.atn'));

app.doAction('TrimGem','Set 1')

// reference open doc

var doc = app.activeDocument;

// set save options

var opts = new ExportOptionsSaveForWeb();

opts.PNG8 = false;

opts.transparency = true;

opts.interlaced = false;

opts.quality = 100;

opts.includeProfile = false;

opts.format = SaveDocumentType.PNG; // Document Type

// save png file in same folder as open doc

activeDocument.exportDocument(doc.path, ExportType.SAVEFORWEB, opts);

activeDocument.close(SaveOptions.DONOTSAVECHANGES); //close image without saving changes

function pasteInPlace(enabled, withDialog) {

    if (enabled != undefined && !enabled)

      return;

    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);

    var desc1 = new ActionDescriptor();

    desc1.putBoolean(sTID("inPlace"), true);

    desc1.putEnumerated(cTID('AntA'), cTID('Annt'), cTID('Anno'));

    executeAction(cTID('past'), desc1, dialogMode);

  };

function createSmartObject(layer)

{

    var idnewPlacedLayer = stringIDToTypeID( 'newPlacedLayer' );

    executeAction(idnewPlacedLayer, undefined, DialogModes.NO);

}

Not sure about VB but with JS you define a mask for selecting files:

//scrFolder defined as the source folder in code
var searchMask = '*shadow*';
var fileList = srcFolder.getFiles(searchMask);
