Pooling Wisely for Oracle Data Provider for .NET

2007-11-12T17:22:00.000+05:30

Use the Decr Pool Size and Incr Pool Size properties wisely when you use ODP pooling. Decr Pool Size Controls the number of connections that are closed when an excessive amount of established connections are unused, and Incr Pool Size Controls the number of connections that are established when all the connections in the pool are used. When a connection pool is created, the connection-pooling

XmlSerializer Worries and Generating Typed Serializers

2007-11-02T12:50:00.000+05:30

The simple constructors of XMLSerializer class caches the typed serializer once it is generated. When you use XmlSeializer to serialize a type, XmlSerializer will create a dynamic assembly on the fly containing the serialization code. When XmlSerializer is invoked from your application, The XmlSerializer constructor will reflect the type you are passing to the XmlSerializer constructor, and

Unloading assembly from the Appdomain

2007-11-02T12:10:00.000+05:30

It is pretty sad that Microsoft is not providing an ideal way to unload individual assemblies from an application domain :( Right now, if you want to unload individual assemblies, you have to create another app domain, and then load your assemblies to that, and unload the entire app domain once you are done. But this approach has few problems If you are loading your assembly to a separate

Frameworks For .NET Development

2007-01-14T13:11:00.000+05:30

Here is a little bit of information regarding some good frameworks, for .NET application development. Traditionally, we have the presentation layer, business logic layer, and the data logic layer. In these layers, things like Exception handling, logging etc can be common. For example, Microsoft Enterprise Library blocks offers such common functionalities, as different functionality blocks.

Dreaming About An XML Based Pre-Processor for Dotnet

2006-06-05T19:08:00.000+05:30

A good concept I had in my mind is developing a pre-processor for .NET compilers, to convert an XSD data structure definition in a VB or C# source code file to equivalent code. Right now, if I need to specify and use a data structure in XSD, First of all, I have to create an XSD schema Use xsd tool or xsdobjectgen to map it to a set of classes or the Document Object Model. Use the

Continuous Integration

An XML based programming language

2006-06-05T19:00:00.000+05:30

I recently found an interesting 'language' from http://xplusplus.sourceforge.net/ - X Plus Plus - which is an object-oriented language that is entirely based on XML's syntactical structure. I had some thoughts about developing a language like this long back, but I felt that XML is not so powerful when it comes to expression handling and evaluation. Just think how much difficult it is, to

Your Internet Information Server crashed, and you reinstalled it. Now, how to re install ASP.NET so that IIS can load and execute aspx pages? There is a tiny tool aspnet_regiis.exe in your Microsoft.NET system folder (e.g, at C:\WINDOWS\Microsoft.NET\Framework\vx.x.xx). Execute aspnet_regiis.exe -i (don't foget the -i switch) in the command prompt.

Creating custom attributes for metadata

2005-04-14T17:36:00.000+05:30

Do you want to create custom attributes for describing your functions and classes when developing .NET projects? First of all, create an attribute class, derived from System.Attribute. Now, I'll create an attribute class named DescriptionAttribute. Mark it with AttributeUsageAttribute (it is a system provided attribute), to show that this class can be used as an attribute. <

XSD Object Generator

2005-04-05T21:37:00.000+05:30

XSD Object Generator (xsdobjectgen.exe) tool from Microsoft is a powerfull tool for working with Extensible Schema Types. For example, consider that you need to create an object model from a schema with cross references. XSD Object Generator can identify such references, and it will create a collection for child elements. That is excellent, isn't it? The classes generated are suitable for both

Patterns And Practices - GOF Patterns and more

2005-03-20T13:04:00.000+05:30

In real world application development, you see recurring problems. Once such an issue is addressed, the we addressed that problem can be re-used. Such reusable recurring solutions are called patterns. For example, if you need to create a class with only single instance can exist, you use a pattern called Singleton. The GOF (Gang Of Four) patterns are used widely these days. See Design patterns
