1 1 2 - είναι ο Πανευρωπαϊκός αριθμός εκτάκτου ανάγκης (ενιαίος για Αστυνομία, Ασθενοφόρο ή Πυροσβεστική) και αντικαθιστά όλους τους αριθμούς που χρησιμοποιούσαμε μέχρι σήμερα. Η κλήση είναι δωρεάν από κινητό και σταθερό. Το σημαντικότερο όλων: εντοπίζει τη θέση του καλούντος για όσους ταξιδεύουν και δεν γνωρίζουν την ακριβή θέση του ατυχήματος. Δυστυχώς όμως, σύμφωνα με έρευνα της Διαβάστε περισσότερα »...

WorldCreator a module designed to work with Xaf can really work without it!!!! Suppose you have a non xaf application and you use Xpo as your dataLayer and you want dynamic types then WorldCreator can for sure help you. You just reference WorldCreator and eXpand .BaseImpl assemblies and use an approach similar to the specs bellow [Test] public void Can_Create_Types_In_A_Non_Xaf_Context() { new PersistentClassInfo(Session.DefaultSession){Name = "Test" }.Save(); var typeCreator = new TypeCreator( new TypesInfo( new List<Type> { Διαβάστε περισσότερα »...

Just came across a very nice tutorial on how to implement AJAX with client-side JavaScript and some server-side PHP . The nice thing with it is that it doesn't use any special JavaScript library to hide the details, so it serves as a good insight on how client and server interact and what content is exchanged when you use AJAX to update a page's content without refreshing the whole Διαβάστε περισσότερα »...

The Problem 1 A common requirement in any OOP application is the ability to filter a listview of objects according to their childs in whatever level they belong. eXpand can solve the above by the use of propertypath filters. So in an Customer—>Orders--->OrderLines relationship the filter bellow are enough to filter your customer list view according to any property value of their Orders child collection with the one bellow you can filter customer list view by any property value of orderlines collection of customers orders collection In the video bellow i demo 1. the above functionality that is hosted at eXpand.ExpresApp assembly, 2. eXpand.ViewVariants module for creating views without the model editor (that is badly needed now that we can have multiple Διαβάστε περισσότερα »...

I came across a very nice sample on how to write a PHP form to send e-mail (using POST form action [aka HTTP request method ] and PHP's mail function). The sample was simple enough, but thought I should add some explanation since a user had been asking how it works: At start it checks if it’s rendering the page the 1st time (same goes if page was refreshed) or if it’s redrawing it as Διαβάστε περισσότερα »...

WorldCreator is a xaf module that provide dynamic persistent types for your application and runtime members for your existing classes. That means that you can define dynamic types at runtime through a UI (xaf views) save them in the database and let your imagination free !!! Installation Very simple you just register the selected assemblies bellow and add the required classes you want from .Persistent.BaseImpl At my previous post IOC by BaseImpl I have explain the use of DevExpress.Persistent.BaseImpl assembly so in the same concept eXpand now has its own eXpand.Persistent.BaseImpl that will host a default implementation of persistent interfaces used from eXpand As you can see at the above image there are to types of prefixes on those classes Persistent—> Διαβάστε περισσότερα »...
