This month's installment represents the final column in a series of three focusing on programming events. In the previous two columns, I showed you how to define and raise events (see Basic Instincts: Programming with Events Using .NET and Basic Instincts: Static Event Binding Using WithEvents). I also explained how to wire up event handlers using both dynamic and static event binding. This month I am going to conclude my coverage of events by showing some practical examples of handling some of ...

As a VB developer one thing that I've been wondering how to achieve is providing my assemblies with a more professional look by adding summaries, descriptions, help and remarks to the classes, members and parameters. This help is often seen when using commercial assemblies both in the Object Browser and programmatically as you hover over a member shown in your IntelliSence list. Very regularly we must all think, OK what exactly does this parameter mean and even more importantly what does the met...

I had spent a little time cleaning up all of my DRAWING routines in my project DesignLab(C)2007 before commiting to building a class library. Just to clarify, there is no reason to do this without cause. Cause represents the need/desire to use routines in various programs. I had begun to see ways to use my drawing engine in other applications, such as Screen Savers and animation....

I got a requirement to plot a list of 3D points on a graphics display. The list of points is generated by some other software. I had to do this using Dot Net. I am not using DirectX or any other library. I have created a 3D Geometry library with just basic classes like Vector, Matrix and Point. A test application also has been developed to test this library. The test application reads a point data file and draws lines connecting the read points. It also has options to view the 3D object along di...

For my last project, I developed a nice library in VB.Net for Credit Card Processing. It used sockets and the message format between our servers and those of Citibank was based on a variant of ISO 8583. Calling this library from ASP.Net pages was working fine. But, my Project Manager wanted it to be called from some old VB 6 and classical ASP applications too. So, this scenario demanded that there should be some sort of COM interface to access that component. Also, our Tech. Lead wanted to use L...

Once you've made a namespace accessible to your code, you can access any of the types it contains. In this section, we'll survey the types that a .NET namespace can contain. In VB.NET, classes are reference types; that is, when you create an instance of a class in code, you work with a pointer (or reference) to the object rather than with the object itself. This is similar to previous versions of Visual Basic....

OELibrary is open source COM based component written in C++. I have created this component long back when I used to work with EfExtra e-solution pvt ltd. There it used to be closed source, paid software, but due to some personal and professional reason, this component has not able to see light of day. After around three year, when I enquired about the same, Saurabh (Director, EfExtra) happily agreed to launch project open source, rather then just lying idle in backup of computer....

It was decided by the powers that be to take an existing, in-house application, and release it externally. This application used a proprietary class library, which could not to be included. However, the application would need the same functionality in a new class library when released externally. Furthermore, the existing in-house class library was scheduled to be rearchitected in the near future....

Just wondered around the other day and tried to find a ready made class library of how to get COM+/ActiveX Type Library information from registered objects. Since I couldn't find anything, I decided to quickly implement my own version.
The basic idea is that you should create new object of type TypeLibraries and with a single call of method GetAllFromRegistry() should populate this with information from registry. The form of collection is CollectionBase, so basically this should be easy t...

The default .NET string library comes with several functions to manage strings that are quite helpful (Substring, Compare, IndexOf, etc.). The problem is that the amount and variety of these functions is very limited. I find myself constantly needing string handling functions beyond those that are given, and I find myself constantly rewriting the same functions over and over again for new projects. So, I have put together a library of functions that I have found useful. Some are very basic and s...

Using this class, you can do things like create join statements more easily, use an array or collection as the fields list (or values list for INSERT and UPDATE queries), and change parts of the SQL statement by setting properties, as opposed to managing a long string.

Every so often, while happily coding along in .NET, I’ll run into an object with a few methods that just don’t make sense. The .NET ListView object was just one of those. In VB6 it was a piece of cake to sort by columns in a ListView. All you did was pass it the index of the column you wanted to sort by. Now, in .NET, things have gotten a little bit more complicated. The gist of the new method is this: you must create your own custom class that implements the IComparable interface and overrides ...
