Using Extension Methods |
|
How often do you want to modify existing classes to have extra methods? Quite often. Right? When you have source code of the classes under consideration at your hand then things are easy. You probably just add the extra methods to those classes. What if you don't have source code? Well. In such cases one approach is to inherit the existing classes and add extra methods to the child classes. However, this way may not be always correct and possible in terms of your application design and OO principles. Luckily, C# offers a quick way to extend your class functionality through a feature known as Extension Methods. Extension methods allow you to extend existing types without inheriting them. This article is going to throw some light on this handy feature. |

Working with Binary Large Objects (BLOBs) Using SQL Server and ADO.NET |
|
Sometimes, your data is not limited to strings and numbers. You need to store a large amount of data in a SQL server table. Documents, raw files, XML documents and photos are some examples. SQL sever provides special data types for such large volumes of data. In this article, I will discuss how to read and write Binary Large Objects (BLOBs) using SQL Server 2005 and ADO.NET. |

भाग 4 : मी नोकरी सोडतो |
|
साधना हळूहळू दृढावत होती. मन आध्यात्माकडे अधिकच आकर्षिले जात होते. या सगळ्याचा परिणाम असा झाला की माझे अन्य गोष्टींवरील लक्ष उडाले. माझ्या नोकरीतील कामावरही त्याचा परिणाम झाला. कशात लक्ष लागेना. सतत साधनारत रहावे, इश्वरचिंतन करावे असे वाटत असे. बरं माझ्या मनातले कोणाला सांगावे तर 'एव्ह्डया लहान वयात देव देव कशाला करतोस. त्यापेक्षा कामात लक्ष दे.' असा सल्ला मिळण्याची भिती. |

Using LINQ in ASP.NET (Part 4) |
|
In the Part 1 and Part 2 of this series we discussed how to use LINQ to SQL features to query and manipulate data. Part 3 introduced you with the inbuilt LINQ to SQL class designer. The LINQ to SQL class designer not only allows you to design classes visually but also saves reasonable amount of time otherwise needed to write equivalent code manually. Another such handy feature available to ASP.NET developers is LINQ Data Source Control. In this article I will explore this control with examples. |

देवाच्या डाव्या हाती (भाग 3) |

मराठी माणसाला ज्ञानेश्वरीची निराळी ओळख सांगण्याची गरज नाही. मीही ज्ञानेश्वरी विषयी बरेच वाचले होते पण संपूर्ण ज्ञानेश्वरी प्रत्यक्ष अभ्यासण्याचा योग कधी आला नव्हता. त्या दिवसानंतर प्रथमच मी ज्ञानेश्वरी अथ पासून इति पर्यंन्त वाचून काढली. सहाव्या अध्यायाने मला वेडावून टाकले. |

Using LINQ in ASP.NET (Part 3) |
|
In the Part 1 and Part 2 of this series we discussed how to use LINQ to SQL features to query and manipulate data. We also learnt to call stored procedures via LINQ to SQL. In the previous examples our approach was manual in that we ourselves created the custom data context and entity classes. Visual Studio comes with an inbuilt designer to perform the same task. This article will teach you how to use the designer and consume the created classes in your application. |

एक संथ, शांत व काहीशी कंटाळवाणी दुपार. माझा पहिला वहिला पगार नुकताच हातात पड्ला होता. सगळ्यांना 'पहिल्या' गोष्टींच जस अप्रूप वाटत तसच मलाही होतं. अर्धा दिवसांच्या सुटी नंतर ऑफिस मधुन निघालो. येतांना काही मित्रांना भेटायला गेलो. माझ्या सारखाच बहुतेकांचा पहिला पगार झाला होता. साहजिकच गप्पांचा ओघ पहिल्या पगारा भोवती घुटमळत होता. कोणाला घरच्यांना व मित्रांना पार्टी द्यायची होती तर कोणाला खरेदी करायची होती. घरी परतताना आपण पहिल्या पगाराचे काय करावे हा विचार मनात घुटमळत होता. विचारांच्या तन्द्रीतच रेल्वे स्टेशनात घुसलो आणि एक विचित्र गोष्ट घडली... |

Using LINQ in ASP.NET (Part 2) |
|
In the Part 1 of this series I discussed the basic operations of LINQ to SQL. By default when you use LINQ to SQL queries as shown earlier, they internally use SQL statements i.e. INSERT, UPDATE, DELETE and SELECT. In many real world applications you use stored procedures. Luckily, LINQ to SQL has a way to call stored procedures from your application. It involves bit of a work as compared to almost automated way discussed earlier. In this article I will explain how stored procedures can be consumed using LINQ to SQL. |

Beginning XML with C# 2008: From Novice to Professional Published! |
|
My latest book on XML is now available. Here is a brief description:
Beginning XML with C# 2008 focuses on XML and how it is used within .NET 3.5. As you’d expect of a modern application framework, .NET 3.5 has extensive support for XML in everything from data access to configuration, from raw parsing to code documentation. This book demystifies all of this. It explains the basics of XML as well as the namespaces and objects you need to know in order to work efficiently with XML. You will see clear, practical examples that illustrate best practices in action. With this book, you’ll learn everything you need to know from the basics of reading and writing XML data to using the DOM, from LINQ and SQL Server integration to SOAP and web services.

देवाच्या डाव्या हाती (भाग 1) |

गेल्या वर्षी माझे Kundalini Yoga: Concepts & Practices हे पुस्तक प्रसिद्ध झाले. त्या नंतर अनेक वाचकांची पत्रे व Emails आल्या. अनेकांची माझे स्वत:चे कुडंलिनी जागृतिचे अनुभव जाणून घेण्याची इछा होती. ही लेखमाला त्याचीच परिणती आहे. |
