Keep forgetting how to add a framework:
cd /Libarary/Frameworks
ln -s /Developer/workspace/EkjaFramework/dist/EkjaFramework.framework/ EkjaFramework.framework
Online presentations S5 is a great tool for setting up slides shows in a browser. Check out the intro.
SQL Server has got identity for primary keys( see this article ) that was preventing me from inserting into a table with EO.
To get by this you can just set the identity insert to on with:
EOUtilities.rawRowsForSQL( ec, modleName, "SET IDENTITY_INSERT tableName ON", NSArray.EmptyArray );
NSArray rawRows = EOUtilities.rawRowsForSQL( ec, modleName, "SELECT MAX(idenityColumnName) as NR FROM tableName", NSArray.EmptyArray );
NSDictionary rowWithPK = (NSDictionary)rawRows.objectAtIndex(0);
Object maxPK = rowWithPK.objectForKey("NR");
int primaryKey = (new Integer(maxPK.toString())).intValue();
When traveling around one might feel the need to have access to Icelandic keyboard input. Only tested this on IE, need to enable other browsers... sometime ;)
When you can't save the icelandic text, it's good to have a quick way to convert Icelandic into HTML
Right clicking a message will bring it up in a floating container, pretty neat.
Creating a cover method for the parameter with:
context().request().stringFormValueForKey( "parameter" );
When my WebObjects span over a lot of space you can also set the name property of the closing WO tag to distinguish where that WO ends.
... lots of content
Set you user defined dictionary
A lot of the words we use in our comments are specific to our work. You can add your external dictionary by doing the following:
Open Eclipse Preferences - General - Editors - Text Editors - Spelling
Under Dictionaries set a file for the User defined dictionary
Add -Xmx400M in the Arguments launch configurations.
400 is the size of the VM heap size in MegaBytes in this example, the default size is 64.
Run any of your projects simultaneously.
Browser shortcuts to all of your projects.
Open the launch configuration for you project and change the WOPort parameter to a unique number( ex. 1200 and up )
In the WO launch configuration add:
-Dis.us.useDevelopmentDatabase=true
Click the little triangle next to the Debug As... bug icon and select Organize Favorites
Click the Add button to insert a new launch configuration onto the top of the Debug As... list.
Open Run - Open Debug Dialog
Under WOApplication you can change the settings of each of your launch configurations, and add new ones.
Open Eclipse Preferences
Under WOLips and Launch you can change the settings
In the WO launch configuration set:
-WOAutoOpenInBrowser=false
Add the following parameter into the WO launch configuration:
-WSAssistantEnabled=false
A WOImage with data bound to NSData( read from DB ) was not showing up on print.
Binding the "key" to a unique identifier for every image did the trick.
Hugi pointed this out to me, he had run into it some years ago, seems the NSData is only kept for a short period of time in the cache and setting the key will extend it's lifetime there.
Find text in files:
grep -c -r pattern file
-c fyrir count, telur hverstu oft kemur fyrir
-r fyrir recursive, fer ofan í undirmöppur
e.x. grep -c -r logi *
search all files/folders for "logi"
...havn't tried the "find" ;)
du -hcd 1
list all directories, down 1 level( d 1 )
in human readable form (h) and total count( c )
ls - lt : returns (l)ist ordered by (t)ime
head : return top 10
=>ls -lt | head
ls -1 return single column name only
export PATH=$PATH:/opt/subversion/bin
Go to folder to work with
to commit: svn commit -m "Message description"
When working with JavaScript I often need a unique ID for the current component I'm woking with:
ERXStringUtilities.replaceStringByStringInString( ".", "_", context().elementID().toString() );
I wanted to enable the user to go back to the previous page without using a WOActionResults to set the name of the component calling the nextPage. WOContext has a method called page that did this for me with ease ;)
String previousPage = context().page().name();
I just learned that Gmail has a build in spell checker. The nice thing is that it works with a lot of languages, including Icelandic ;)
Need to create a wocomponent instance in java, you'll need : Application.application().createContextForRequest( new WORequest( "GET", "", "HTTP/ 1.0", null, null, null) ) to create the request
Created a WOFileUpload and connected the inputStream attribute to an input stream but nothing worked, kept getting a NP untill I connected FilePath to a String variable, then the WOFileUpload worked like charm( annoying charm that took too much of my time to figure out ).
// Use SimpleDateFormat to format the display of date Strings
SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy");
return sdf.format(new Date());
// Read each line of the file infile.txt
BufferedReader rdr = new BufferedReader( new InputStreamReader(new FileInputStream("infile.txt"), "ISO-8859-1"));
String line = rdr.readLine();
I need to access a localalized strings file for the right language and I don't like the Localizer method.
I wanted to access it through Application and in the WOD files by simply adding "application.@ls.MY_STRING_TO_GET_FROM_LOCALIZED_STRING".
Added the following to Application.java:
public Object valueForKeyPath( String keypath ) {
// Catch all keypaths starting with ls and do whatever you want with it
if( keypath.startsWith( "@ls" ) )
return localizedStringForKey( keypath.substring( 4, keypath.length() ) );
return super.valueForKeyPath( keypath );
}
public String localizedStringForKey( String key ) {
return WOApplication.application().resourceManager().stringForKey( key, "localizedStrings", "!!LOCALIZED_STRING_NOT_FOUND!!", "app", languages() );
}
