• How to resize the columns of the grid databound to an array at runtime?

  While working on the new product (and that's why the break) we got into a DataBinding situation. We had a DTO class, something like this public class Employee { private string employeeName; private string employeeId; public string EmployeeName { get ...

• Loading two versions of an assembly that are not in the GAC

  Many a time you might face this issue. Especially when you are using a third party component, which uses an older version of an assembly, of which you are using a newer version. Pre 2.0 (and I do not know for sure of 2.0) compiler compliant to the CLS... Posted Apr 13 2005, 12:04 AM by rsakalley with | with 8 comment(s) Filed under: Code

• Using AppDomain.Unload II

  There were a few mistakes in the last post on the AppDomain.Unload solution (thanks Manoj for pointing out) (John Papa wanted to know why I did not use LoadFile, thanks John, now I know should have written that MarshalByRef, just forgot it completely...

• Assembly.Unload? Use AppDomain.Unload instead.

  Well we ended up writing a VS.Net plugin to add to our developer testing tools (something like NUnitPlugin, but different). Not much, but almost the whole program was written and then there was this problem that all VS.Net plug-in writers face, atleast...

• Multiple overloads with distinguishing parameter as object is dangerous

  From John Papa's post to Jackie Goldstien's that quoted Pablo Castro[MS], got these words that were somewhere in my mind but never expressed. Thanks all. In general, having multiple overloads where the distinguishing parameter type is “object” in one... Posted Apr 06 2005, 11:37 PM by rsakalley with | with 10 comment(s) Filed under: Code

• Casting and Overriding III

  The piece of code in the previous post would naturally give a warning, as Class B's member Foo() hides Class A's Foo. You either need to override it, or write a "new" Foo. What about the following two - using System; class A { public virtual void Foo... Posted Mar 03 2005, 09:06 AM by rsakalley with | with 11 comment(s) Filed under: Code

• Casting and Overriding II

  On the lines of Geoff's post (sorry Geoff for doing this without permissions), what will be the output of the following program ? (and why?) using System; class A { public virtual void Foo() { Console.WriteLine("Call on A.Foo()"); } } class B : A { public...

• NUnit and automatic method input parameter verification

  Almost all methods depend on one or more input parameters. To verify each and every one of these parameters, for boundary conditions, nulls and such generic cases, becomes an overload, for each method in a class. It also leads to writing repetitive test...

• Developing a multi-template website.

  While developing a product that automates the creation of a web-site, an eCommerce one or else, you need to know that having a set of similar looking web-sites is not what your customers would want. When B uses your product to create his front-end on... Posted Feb 10 2005, 12:13 AM by rsakalley with | with 7 comment(s) Filed under: Code

• Suppress serialization of a public property

  A post on one of the microsoft groups prompted some research, I was bent upon finding out a solution one way or the other.

• "as" or "is" for decision making

  Thanks to Michal Boleslav Mechura, who pointed me back to Jeffrey Richter's "Applied Microsoft .NET Framework Programming" on this.

• Get IP Addresses of all machines in your network

  I searched the .Net BCL for a solution to this, and then I had to go back to net.exe to do this. This is a very brittle solution, so if you have a better one, dont forget to enlighten me. using System; using System.IO; using System.Diagnostics; using...

• Speed up your lousy data reads

  I had worked on this almost 2 years back, .net was kind of unknown then, and we were probably the first team in Bangalore working on it. Problem : Your query resultset (may be a DataSet ) has 50000 rows with 5 ( or > ) columns. You can't optimize the...
