ECO - get typed list

2009-03-04T12:16:00.002+01:00

After using my own ORM for a long time, I came across the ECO framework (http://www.modelmakertools.com/). This framework allows you to nicely develop in a modeldriven way. Nice integration with Visual Studio.

Basic typed list retrieval:

IList myList;
myList = EcoSpace.Ocl.Evaluate("Application.allInstances->first").GetAsIList();

5 Things You Didn't Know About Me (meme)

2007-01-18T01:21:00.000+01:00

I got blog tagged (some chain-thing waving the blogs) by Anders Ljusberg (Ljusberg) and also saw a lot of other ‘5 things posts’ passing by so I gave it a go. Here a tip of the iceberg of things u prob didnt know:

1. Allthough I got involved in computers very early (C64, basic programming and a nice 8bit interface to develop my own lightshows ;-), good old ‘pokes’ ), I didn’t started my carrier as a software developer, I studied microbiology first and worked at that time as a waiter, milked cows and other ‘hardwork’ stuff. Also worked as a lightjokey in a club (working hrs where the same as nowadays :-) )

2. My first car was a green 1ltr Subaru justy which could fly if u drove it fast enough over the ‘bump’ on the way home from school.. I crashed it later on an early morning in the rain/snow :’-( R.I.P.

3. In contrast of developing/designing apps and sitting still all day, I like hiking through the mountains (going to visit Nepal at the end of march), back to basics and clearing the mind.

4. My first own place to live was a room (4mtr x 4mtr) in Utrecht (Ludgerusstraat) I rented it from a pilot and a stewardess couple who didn’t like it when about 8 drunk friends crashed the night on the floor, hehe...

5. Normally I don’t cook much (at least when you don’t count the microwave and the oven 10-15 min meals + 3 vitamin pills), but when I want to, I’m a pretty skilled cook J

Don’t know much direct related ‘tech-bloggers’ so here some ‘non-tech’ friends..

Fun with Singletons in C# 2.0

2007-01-11T19:32:00.000+01:00

With the new generics support given by C# 2.0, some common design patterns can be generalized to work with any type. Exploiting the capabilities given by the type system, reflection, and generics, we can accomplish typesafe modular code customization and automation. Fun with Singletons is just a demonstration of the array of possibilities that C# 2.0 features introduce.

The iBATIS Data Mapper framework makes it easier to use a database with Java and .NET applications. iBATIS couples objects with stored procedures or SQL statements using a XML descriptor. Simplicity is the biggest advantage of the iBATIS Data Mapper over object relational mapping tools.

NHibernate for .NET
NHibernate is a port of Hibernate Core for Java to the .NET Framework. It handles persisting plain .NET objects to and from an underlying relational database. Given an XML description of your entities and relationships, NHibernate automatically generates SQL for loading and storing the objects. Optionally, you can describe your mapping metadata with attributes in your source code.

ASP.Net 2.0 WebPart lifecycle with provider/consumer connections

2006-11-05T14:55:00.000+01:00

Working on a large portal project me and my team faced a lot of problems to get the communication between webparts and binding grids right. To make an end to this, I wrote a universal to use "pattern" to avoid unexpected mess.

If microsoft could only make the connectors available (= onprerender#@$) before CreateChildControls, live would be much easier!

In our scenario, we use one 'Action provider' (save/delete and stuff) and one 'ClassID provider' (to communicate ID's between parts)

http://www.overnight.nl/download/WebPartStages.doc

hope this helps, if not contact me, it will drive u crazy!

Another thing to be aware of, you can only set a validationgroup on CreateChildControls, afterwards, again no error, but it wont render#@ How cute when this depends on the provider#$@ thanks microsoft, not!

Automated Testing

2006-10-09T21:37:00.000+02:00

JavaScript presents several challenges when testing user interface components written using "Atlas." With asynchronous operations like web service calls or animation, you have to start the operation and wait for it to complete without blocking before you can verify the result. Postbacks are just as difficult because you have to perform an action that causes a postback and then have the test resume processing where it left off when the page loads again. We have written a JavaScript testing framework, in the ToolkitTests web project, to eliminate these problems when writing tests for your components.

Another glitch in the webpart matrix, Item has already been added. Key in dictionary: 'ID' Key being added: 'ID'

When setting your datasource to a gridview in the override createchildcontrols you might run into the error "Item has already been added. Key in dictionary: 'ID' Key being added: 'ID'" on a Postback. Even when everything seems okay. Somehow the key gets added twice$#@ Well, to solve this problem, move your databinding stuff to the OnPreRender event.

wtf#$@ hidden webparts, validation troubles

2006-10-01T23:20:00.000+02:00

On a portal i'm developing (ASP.NET 2.0, C#, webservices, webparts) I ran into the following glitch!

My colleague worked on a WebPart I build and came to me asking why some evenhandlers didnt got firedup. Also the validation acted weird, allthough the summary showed up normally, the clickevent fired without page being valid. I noticed that the page had a JavaScript error and offcourse untraceable. Well what do you do in that case, you know the part worked fine when u left it there so you demolish nearly everything to get to the bone. And what do you know, still no luck #$$@#$ . More by luck then by wisdom I saw the createchildcontrols event got fired 3 times a postback/pageload... mm.. thats strange, only one part on the page.. Conclusion, there must be more then one of the same part in the profile but set to close. I reset the page, and all my troubles where gone.. how cute is that#$@

In short:
Got strange JavaScript errors on your webparts, events dont fire, validations go weird, try resetting you webparts page.

ATLAS + Masterpages + WebParts - webservice troubles

2006-09-28T19:51:00.000+02:00

As you could have red in my Ajax presentation sheets (http://dotnetpret.blogspot.com/2006/09/ajax-buzz-or-here-to-stay-lecture.html) used webservices must origin in the same domain, but not only that, there are also issues with different subdirectories. Today I sufferd the consequents of this issues, in my test page the ATLAS autocomple control I build worked fine, putting the same control on a webpart and using this part in my on masterpages based portal nothing happend! and worse, no errrors, not even JavaScript error.

To cut the story short. When using asynchronous callbacks in your masterpagebased pages, put your webservice (*.asmx) files in the same directory as the masterpage!!!

VS2005 - template versus snippets

2006-09-24T14:52:00.000+02:00

I'm using codesnippets a lot, also for instant building of our own custom classes (inheritance, bunch of overloads and methods) Now I remembered that it is also possible to create custom templates. For class templates this is a bit more faster because by selecting your custom template (add new item...) you can modify your template so it will fill in the namespace and class name automatically.

Summary:
Class structure - > use templates
properties/methods -> use snippets

Possible parameters (put into your template like this: $myparam$)
itemname
The user-provided name from the dialog. This value is often used for naming classes and files.
safeitemname
The same as itemname but with all unsafe characters removed.
safeitemrootname
The name of the root item, which can be used for multi-item templates. For example, if you have partial classes, or a code-beside or code-behind scenario, you can use this item in the secondary files when you need the safeitemname of the main item being created.
projectname
The user-provided name of the project for a project template.
safeprojectname
The user-provided name of the project for a project template with all unsafe characters removed.
rootnamespace
The root namespace of the project for an item template, which can be used to replace the namespace in a project item source file.
guid[1-10]
A GUID that can be used as a unique identifier for uses such as project GUID in the project file. You can specify up to 10 different GUID parameters using the syntax: guidx, where x is a number between 1 and 10.
time
The current time in the format DD/MM/YYYY HH:MM:SS.
year
The current four-digit year.
username
The Windows username of the logged-in user.
userdomain
The Windows domain of the logged-in user.
machinename
The name of the machine where the template is being used.
clrversion
The version of the common language runtime being used.
registered-organization
The registered organization of the user based on the system settings.
wizarddata
A single string that can be any XML or string data included in the WizardData element in a template metadata file.

Build Smarter ASP.NET File Downloading Into Your Web Applications

2006-08-26T01:06:00.000+02:00

Chances are good that your users need to download files from your organization's Web site. And since providing a download is as easy as providing a link, you certainly don't need to read an article about the process, right? Well, thanks to so many Web advances, there are many reasons it might not be that easy. Maybe you want the file to be downloaded as a file rather than shown as content in the browser. Maybe you don't yet know the path to the files (or maybe they're not on disk at all), so those simple HTML links aren't possible. Maybe you need to worry about your users losing connectivity during large downloads.
In this article I'll present some solutions to these problems so your users will have a faster, error-free downloading experience. Along the way I'll discuss dynamically generated links, explain how to bypass default file behaviors, and illustrate resumable ASP.NET-driven downloads using HTTP 1.1 features.

No tool is an island, Subversion™ needs to integrate with the other tools you use on a day to day basis. For example, Subversion does not have its own graphical user interface, it is completely driven from the command line. Many developers like this but others prefer a GUI or a direct integration with their favorite IDE.

Loading Web Parts into a catalog at run time

2006-08-20T20:27:00.000+02:00

Working on a large news portal I was searching for a way to add webparts to the catalog at runtime. Well here an article describring the solution. This actually works very good, based on reflection, a must try!

ASP.NET 2.0 introduces the Web Part framework outside of the SharePoint environment. This allows developers to build applications that are configurable by the user at run time. The CatalogPart class is used to provide a list of Web Parts to users at run time. Out of the box, ASP.NET 2.0 does not provide a catalog that is populated at run time. This Support Voice column will discuss how to create a custom catalog for this purpose.

AJAX Meets ASP.NET 2.0 Membership Management For IIS

2006-08-20T01:11:00.000+02:00

Microsoft ASP.NET 2.0 Member/Role Management with IIS, Part 3: AJAX Enhancements with Microsoft’s Atlas

Without actually running the web application, the only visual change the user can see in the AJAX enhanced version of this application is that there is no search button above the user list. This is because with AJAX, as the user types in the search criteria, the list of users is automatically restricted to the search criteria defined by users that begin with what is typed. Notice in the screen shot below, ch is entered into the username textbox and just the usernames beginning with ch automatically appear.

The Visual Studio 2005 IDE may corrupt the deployment files for a Web Setup Project and for a Setup Project

2006-08-17T10:25:00.000+02:00

Building setups frequently these days, I ran into problems with the setup project. At a certain you will get problems with updating references. Trying to refresh will get you an error. This is a known issue as you can see on the linked page. I found a simple solution. Mesh up .vdproj file in notepad, save, VS will now ask you to reload project and will fail. after that, change the file to its original state. Reload the project with right click in VS, and there you go. Its wacky but it works

Adding - removing add-ins

2006-08-17T01:43:00.000+02:00

A quick note for the people following the OvernightPowerAdd-In suite developments. Installing, uninstalling and installing new versions can give some trouble. when uninstalling the add-in, some references in VS2005 are still ghosting around. A quick fix for this problem is to make sure VS does uninstall the old dll. You can do this by closing VS, go to your addin dir and change the ref file by changing its dll path to something nonexcisting. Start VS and confirm the removal, now you can uninstall the old versioin (after renaming the add-in ref name to original name). After that install new version. Having trouble with this procedure, or you know a simpler way, pls send me an email fh_kroo{no-spam}ndijk@yahoo.com

Exception handling in C# and ASP .Net

2006-08-11T13:19:00.000+02:00

Exception handling is an in built mechanism in .NET framework to detect and handle run time errors. Exceptions are defined as anomalies that occur during the execution of a program. The .NET framework provides a rich set of standard exceptions that are used during exceptions handling. Exception handling is one of the major feature provide by .NET. There might be various reason to handle exception, this can be caused due to improper user inputs, improper design logic or system errors. In this scenario if application do not provide a mechanism to handle these anomalies then there might be cases the application may crash. .NET run time environment provide a default mechanism, which terminates the program execution.

This happens most days. Somebody will have some sort of issue with their computer and will come bleating to me that it doesn't work. I've learnt now that the first step is adopt an attitude of healthy scepticism and to require a demo of the problem. I go over to their desk and they start to show me. And lo and behold, it works... perfectly. It happens so often that I've been forced to come up with a theory for why this is. I do believe the afflicted users seeking my help. I'm sure it was misbehaving before but why does it suddenly seem to start working the moment I am standing ominously peering at it?

What's new in System.Xml 2.0?

2006-08-08T20:35:00.000+02:00

a freshen up article by Aaron Skonnard

System.Xml 2.0 Design Goals

Improving System.Xml performance was a driving force behind many of the changes in System.Xml 2.0. The team invested significant resources and were quite successful. Compared to their .NET Framework 1.1 predecessors, the new XmlTextReader and XmlTextWriter classes are now twice as fast as before, the XSLT performance is three to four times as fast, and XML Schema validation is faster by about 20 to 25 percent.

To achieve most of these performance improvements some significant redesign and targeted optimizations were required. For example, it took some serious reworking to make the .NET XSLT implementation just as fast as its unmanaged predecessor, MSXML 4.0. Now in System.Xml 2.0, the XSLT implementation builds Microsoft intermediate language (MSIL) directly, which is then JIT compiled by the .NET runtime and executed as machine code. The resulting performance is very similar to that of MSXML 4.0 in most cases.

Taking advantage of these performance benefits requires proper use of the new and improved System.Xml library, which I'll discuss in the sections that follow. In addition to performance, the other design goals included enhanced usability, compatibility, and standards. Towards the end of the System.Xml 2.0 development cycle, it became apparent that the System.Xml team really cared about making their offering the most practical and usable solution on the market today. This required some tough choices regarding the feature set, but in the end the library's usability speaks for itself.

The significant difference between the ref keyword and the out keyword is that the out keyword doesn’t require the calling code to initialize the passed arguments first.
A more subtle difference between ref and out is that out parameters must be modified in the called method, whereas ref parameters can be but don’t have to be modified

C# 3.0 is Not Part of .NET 3.0

2006-08-07T15:49:00.000+02:00

.NET 3.0 will be released with Vista. It will not contain C# 3.0, but will ship with C# 2.0.

The major features of .NET 3.0 are: Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF), and Windows CardSpace (WCS, formerly “InfoCard”).

Visual C# 3.0 will be released as a part of the next Visual Studio release.

C# 3.0 will include features like:

Implicitly typed local variables using var keyword, e.g. var i = 5; would be equivalent to int i = 5; and var numbers = new int [] {1, 2, 3}; is equivalent to int[] numbers = new int [] {1, 2, 3};
Extension methods – static methods that can be invoked using instance method syntax (VB.NET developers have enjoyed having this feature for some time now, albeit with a compile time warning)
So called “lambda expressions” -- anonymous methods, which allow code blocks to be written “in-line” where delegate values are expected
Type inference – attempt to deduce argument type when one is not specified during a call to a generic method
Object initializers -- property setting during object construction, e.g.
Point p = new Point{X=0, Y=1};

LINQ (language integrated query) .. not happy with that!, linq = great
Etc.
For complete feature list and examples, please visit http://download.microsoft.com/download/5/8/6/5868081c-68aa-40de-9a45-a3803d8134b8/CSharp_3.0_Specification.doc
