How to zero your application startup time
21 Σεπτεμβρίου 09 11:10 μμ | tolisss | 0 σχόλια   
For this question don’t we all of us spend a lot of time ? But I think it is allowed to use a trick to spend our selves that time. Add to your model to attributes NotifyIcon, MinimizeOnClose. Since I am using Xaf I am going to present that with it but the code should be very similar to any other windows application so here are our attributes NotifyIcon: will add a tray icon for your app at the system tray with a context menu that will allow you to terminate your application and display it when you double click the icon public   partial   class NotifyIconController : WindowController {     public   const   string NotifyIconAttributeName = "NotifyIcon" ;     public NotifyIconController()

ModelArtifactState Xaf Power to the people
02 Σεπτεμβρίου 09 11:34 μμ | tolisss | 0 σχόλια   
Yesterday i was speaking with my friend John Pouliezos and he asked me how to the implement the following  scenario. John has managed to create a SharePoint feature and now he can have Xaf views as SharePoint lists. Cool eh? What he wanted is the following: for specific User roles to be able to filter a specific web listview by parsing the current browser url. Step1 : for specific User roles to be able to filter a specific web Aha sounds like ModelArtifactState’s job a lot. Cause that module is able to enable or disable behaviours /controllers (doing something) using permissions or the model. We are going to use permissions for this one So no code is needed for step1 ModelAsrtifactState module is going to help us. Step 2 : John explain to me the urls are

Since I got many complaints about the low resolution of my videos I am on a search for a better video hosting service than YouTube. Robert suggested to use Silverlight service at Blogger Video embedding resolved but this one looks the same as YouToube. After spending some more time on researching on this I came across http://blip.tv/ excellent hosting service To get an idea how good they are I suggest you read their FAQs They accept almost all kinds of  Videos They are free They do not change the video after uploading The customization of the video playback controls is unlimited . You can configure almost anything on their well design interface I am going to use that excellent service to republish my videos So if you want to see those videos again in good

Bend Xaf Applications with Model Artifact State Module
17 Αυγούστου 09 11:07 πμ | tolisss | 0 σχόλια   
How many times have you said “What a great pattern MVP is!!!” Look for example how is implement the hint engine of main Xaf demo. I will try to explain that implementation. Controllers There is a windowcontroller called AdditionalInfoController and from it 2 controllers derive WebShowAdditionalInfoController and WinShowAdditionalInfoController. What they do? they enable inserting any kind of control as the first control of a view. They are the engine, they implement a behaviour and they also serve as the Observer design pattern Observer pattern: Define a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. I am going to refactor the code from the main demo and create 3 new modules

Continuous integration for eXpand
24 Ιουλίου 09 02:08 μμ | tolisss | 0 σχόλια   
First of all thank you very much for your good words in eXpand . I am going to continue releasing modules and the next one will be a big one so please bear with me. But since I am relasing a lot of code and some other developers contact me that they want to contribute also. I think its time to to move on to apply a more continous integration to our build proccess. What I mean by that? the paragraph bellow was takes from martinfowler.com The easiest way for me to explain what CI is and how it works is to show a quick example of how it works with the development of a small feature. Let's assume I have to do something to a piece of software, it doesn't really matter what the task is, for the moment I'll assume it's small and can be done in a few hours. (We'll explore

I am realizing a new version of eXpand (0.0.0.7) that will contain a configurable low level datastore filtering provider module and I am going to merge Coderush plugins into it as well. You have to download latest version of eXpand from http://code.google.com/p/expandframework/downloads/list and add only the following assemblies into your community folder if you are not interested in eXpand  DevExpress.ExpressApp.ModelEditor.v9.1 eXpand.Utils Wintellect.Threading eXpandAddIns
