Just came back to vienna from the APEX Dag 2011 in Zeist/Holland, organized by the dutch Oracle User Group OGH.
What can I say? It was a really good day with lots of interesting speeches and a very interested audience of 250 people ! Continue reading
A couple of weeks i introduced a Plugin which helps the user to enter a postal address in an APEX Form.
Now i present a Plugin which lets you display an already stored address or location coordinates in a very simple and fast loading Google Map Image (png). Continue reading
Oracle APEX 4.0 brought us a “Search Application” functionality which helps really a lot.
Not only can you search there for strings in your application code, you also can enter an page-id and jump directly to the page.
This is so good, that i thought i go a little further and improve it even more. Continue reading
Recently i had to create a Button among Page Items which should execute a Javascript function.
Sounds easy, but standard Page Item Buttons always submit the Page, which isn’t what i wanted.
So i created this little Plugin…. Continue reading
Ever got a “ORA-01841: (full) year must be between -4713 and +9999, and not be 0” Error when trying to edit an existing user in APEX Administration Panel (Manage Workspaces > Manage Developers and Users) ?
Sometimes you want a user to enter an address which later on can be used to display it on a map. Now you want to make sure, that the user sees what the the map will look like and where his entered address is shown on the map.
This comes in very handy for those users who always seems to forget to enter the whole address.
Wer gerade auf der Suche nach einem geeigneten APEX Workshop in Wien ist, hat hier eine wunderbare Gelegenheit gefunden.
Meine Firma, click-click IT Solutions, veranstaltet zwei Seminare zu Oracle APEX Anfang März in Wien.
Diese Seminare laufen in der Reihe der AOUG Seminare und sind deswegen unfassbar günstig!
Für Mitglieder der AOUG kostet so ein Tag gerade mal EUR 225,- , Nichtmitglieder auch nur EUR 295,- !
Der richtige Einstieg für alle Interessierten, hier bekommen sie einen ganzen Tag lang alles wissenswerte rund um Oracle Application Express vermittelt und “begreifen” Applikationsentwicklung mit gezielten Hands-On Übungen.
Egal ob Entwickler, DBA oder Manager. Nach diesem Tag können sie nicht nur ihre eigene Applikationsentwicklung starten, sondern sie haben auch genug Background um zu entscheiden ob/wie/wo Oracle APEX in ihrem Unternehmen eingesetzt werden kann.
Wer schon Ahnung von Oracle APEX hat, aber die neuen Features der Release 4.0 noch nicht einsetzt, der ist mit diesem Tag richtig beraten.
An diesem Tag dreht sich alles um Interaktivität mit Dynamic Actions, Plugins und den neuen Tabular Form Features.
Aber auch die anderen neuen Features kommen nicht zu kurz:
When that little box on that web form you need to fill in is simply too small to show all your information at once, you wish to make the box bigger.
Some browsers let you change the size of text-boxes (textarea), others don’t. So if the programmer of that page doesn’t give the textarea some javascript to be resizeable you are stuck with the given size.
When you create a Form page with the APEX Wizard it puts all the fields in just one column which can create a very long page.
This can reduce the use experience and usability a lot.
Sometimes it is a better way to put the fields in two (maybe three) columns and present them all on one screen. This gives the user the benefit of seeing all the information at once. Continue reading
A couple of days ago i got an emergency call from someone who attended my presentation at DOAG 2010 about APEX Translations.
Apparently they deleted (by accident) their APEX Translations (which reside in WWV_FLOW_TRANSLATABLE_TEXT$) and have neither a DB-Backup of this table nor a Backup of the XLIFF Files. Continue reading
