The caret synbol( ^ ) in bindings

The caret symbol( ^ ) indicates that the value should be taken from the parent component.

Getting resources from Unit Tests

Since Unit Tests are run from the command line( or Ant ) access to Resources of a WebObjects project are no good with ResourceManager. Simple functions to get resources based on the filesystem:

/**
 * Returns a path to a resource filename in a folder(s) under the root folder
 * */
private String resourceLocationString( String filename, String folder ) {
    String urlToFile = getClass().getResource( "/" ).toString();
    urlToFile = urlToFile.replace( "bin/", "" );
    urlToFile = urlToFile.replace( "file:", "" ); // now we should be at the projects root directory
    urlToFile = urlToFile.concat( folder + "/" + filename );
    return urlToFile;
}

/**
 * Returns data for pdf file
 * */
private byte[] bytesForPDFResource( String urlToFile ) throws FileNotFoundException, IOException {
    FileInputStream in = new FileInputStream( urlToFile );
    byte[] data = new byte[in.available()];
    in.read(data);
    return data;
}

Write data to a file in the filesystem

FileOutputStream fs = new FileOutputStream( ABSOLUTE_PATH_TO_FILE );
fs.write( SOME_DATA );
fs.close();

Executing SQL

Need to call simple SQL commands, like getting the next primary key by calling a sequence:

NSArray rawRows = EOUtilities.rawRowsForSQL( EDITING_CONTEXT, MODEL_NAME, SQL_STRING, NSArray.EmptyArray );
NSDictionary rowWithPK = (NSDictionary)rawRows.objectAtIndex( 0);
Object maxPK = rowWithPK.objectForKey( "NR" );

Pro Tools EZDrummer plug in output

Installined EZDrummer and created a stereo Instrument track in Pro Tools LE 7.1.1 but didn't get no output from the track. I had other audio tracks that worked fine, and creating a stereo audio track got the output from EZDrummer but you need the Instrument track to drop the midi loops onto. After about 2 hours of hacking Pro Tools, reading forms, reading manuals and other desperate measures I noticed that the volume on my Instrument track was turned down and the only thing I needed to do was to crank it up. Since this is not the case with audio tracks tracks I failed to check this...that won't happen again ;)

Symbolic link

Keep forgetting how to add a framework:

cd /Libarary/Frameworks

Then add your framework like this example with EkjaFramework in my Developer workspace:

ln -s /Developer/workspace/EkjaFramework/dist/EkjaFramework.framework/ EkjaFramework.framework

WOCheckBox binding

Keep forgettins it's the cheked binding to use, not value or selection.
