To specify multiple .JAR files at HTML APPLET's tag ARCHIVE parameter, edit the applet tag in the HTML page and change the following parameter: ARCHIVE = "myapplet.jar" to say ARCHIVE = "myapplet.jar,lib/jbcl-rt.jar,lib/jgl.zip" assuming you place all those JAR files together on the server (the "lib/..." ones in a subfolder called "lib") with Διαβάστε περισσότερα »...

If you ever have to work with legacy code directly manipulating BMP image files, this Wikipedia article on RLE is a useful reading, since RLE (Run-Length-Encoding) is one of the popular compression schemes used in the BMP image container format. Although simple, RLE when used on palletized images (especially drawings on simple Paint-like programs) can do a decent compression. Can even Διαβάστε περισσότερα »...

When working with Xaf and MVC pattern in order to create actions we are using controllers and initialize them upon them. The default behavior of Xaf is to place our actions in the default toolbar of our view. What if we want to position our actions somewhere else in the view? Then we need to create a custom detailviewItem and write our code against the interface exposed by the detailviewitem. I really did not like the idea , I really wanted to continue to design my actions behavior against the controller interface so i have added an ActionButtonDetailItem for both win and web platforms that can be installed declaratively using the model like bind it to the action we want like and position it anywhere we want using Dx layout component to create our views like Διαβάστε περισσότερα »...

Ένα μικρό tip που μπορεί να σας σώσει από εκνευρισμό ειδικά αν είστε αρχάριος με τον SQL 2008, είναι όταν πάτε να κάνετε μια αλλαγή σε ένα πίνακα που έχετε ήδη δημιουργήσει, πχ. να αλλάξετε τον τύπο (datatype) μιας στήλης (field). Ξαφνικά παίρνετε αυτό το ωραίο warning pop-up window Για να το ξεπεράσετε και να μπορέσετε να κάνετε τις αλλαγές μέσα από τον SSMS , πρέπει να πάτε Tools --> Options να βρείτε το Designers section και να απενεργοποιήσετε την επιλογή "Prevent saving changes that require table recreation" , όπως φαίνεται παρακάτω: Ελπίζω να σας φανεί χρήσιμο.

I've been recently adding support for QuickTime TimeCode tracks to the JEDI QuickTime library's "qt_QuickTimeComponents.pas" file and I thought I should share a quick reminder on how we convert C structs (records) and unions (sets) into Pascal (Delphi / Object Pascal in this case) records: Structs: struct TimeCodeCounter { long counter; }; typedef struct TimeCodeCounter TimeCodeCounter; Διαβάστε περισσότερα »...

After working with MVC pattern exposed by Xaf I have realized that the best way to to pass parameters between controllers is by using events like public class PricePricetypeController : ViewController { public event EventHandler < AdjustingPriceTypeEventArgs > AdjustingPriceType; public void OnAdjustingPriceType( AdjustingPriceTypeEventArgs e) { EventHandler < AdjustingPriceTypeEventArgs > handler = AdjustingPriceType; if (handler != null ) handler( this , e); } protected override void OnFrameAssigned() { Διαβάστε περισσότερα »...

This one is the most complex implementation of the logic architecture cause this module is really a facade module. ActionState and ControllerState modules are hosted within it. But the implementation for each one of them as you see in the image bellow really looks alike In order to control the different in model schema than the one that is provided bu defaul I have override the require methods of ControllerStateModule public class ControllerStateModule : ConditionalLogicRuleProviderModuleBase <TArtifactStateRule> where TArtifactStateRule : IConditionalLogicRule { public override string LogicRulesNodeAttributeName { get { return ControllerStateRulesNodeWrapper Διαβάστε περισσότερα »...

AdditionalViewControlsProvider is a module that it only knows how to display a given control in a given position . So one could easily define an interface for the parameters needed when this behavior is implemented as public interface IAdditionalViewControlsRule : IConditionalLogicRule { string Message { get ; set ; } string MessagePropertyName { get ; set ; } Type DecoratorType { get ; set ; } Type ControlType { get ; set ; } AdditionalViewControlsProviderPosition AdditionalViewControlsProviderPosition { get ; set ; } bool UseSameIfFound { get ; set ; } } take a note that I inherit IConditionalLogicRule thus logic engine can evaluate Διαβάστε περισσότερα »...

Say you want to make your rules conditional , meaning that you want your rules to be executed when certain criteria are valid for a given object. That is implemented at eXpand .ExpressApp.ConditionalLogic.dll assembly. I have extend ILogicRule interface like public interface IConditionalLogicRule : ILogicRule { /// <summary> /// Criteria to apply when show DetailView or filled ListView /// </summary> string NormalCriteria { get ; set ; } /// <summary> /// Criteria to apply when show ListView empty /// </summary> string EmptyCriteria { get ; set ; } } and create derived classes 1.from Διαβάστε περισσότερα »...

Πριν από μερικές μέρες (στις 4 Μαρτίου για την ακρίβεια) έγινε στο Microsoft Innovation Center μία πρωτότυπη μονοήμερη δωρεάν εκπαίδευση με τίτλο “.Net Training μέρα - όλη μέρα!”, που είχε ως θέμα μια εισαγωγή στο Microsoft .NET Framework.

Xaf architecture and especially the model part is great. What it really teach us is how to parameterized our logic/behavior/code and store that parameter in the model in the form of attributes on already existing nodes or on rule nodes see Xaf Validation system or ConditionalEditorState system. eXpand has provided a similar architecture through its ModelArtifactState module. But after you start using such “ruling” modules for some times the most “logical” question will come into your mind. How I could define a uniform way of describing a behavior in terms of an interface and apply a ruling system upon it. The above problem exactly is address by logic module. What it does ? First look at ILogicRule interface public interface ILogicRule { string Διαβάστε περισσότερα »...

I have been pretty silent the last few weeks , but I have not been lazy so eXpand has now many more modules and features that I am going to speak about in my next posts. A Logic Module has been implemented and that lead to some breaking changes to ModelArtifactState / AdditionalViewControlsProvider modules ModelArtifactState The previous schema of ModelArtifactState rules was like < ModelArtifact > < ConditionalControllerState IsNewNode = " True " > < ControllerStateRule ID = " tests " TypeInfo = " DevExpress.ExpressApp.SystemModule.AboutInfo " IsNewNode = " True " /> </ ConditionalControllerState > </ ModelArtifact > Διαβάστε περισσότερα »...

Well your wait is over, yesterday Microsoft officially released a set of very Διαβάστε περισσότερα »...
