The heading of this post is my latest challenge as I’m continuing to battle out this problem. The domain I’m working (travel and leasure) is such a mess that it has myriad pricing and discounting strategies. At any given instance 0,1 or 1< rules will be applied to a final price.

                   Also the users of the system has to be able to just keep on adding new pricing, discounting rules to the system without any trouble and also to stop applying particular rules when not needed.

My task is to try and solve this the Object Oriented way……………………………..So Naturally the first place I looked up was patterns. Strategy and Composite are two such patterns which looked promising……………….but I need a much closer look in to my problem before making up my mind.

Today I was trying to run a test for the first time in my New Platform VS 2005 from NUnit V2.2 and it failed. It says  ‘System BadImageFormat Exception : The format of the file ‘UnitTest’ is Invalid.’

Tests similar to this ran perfectly fine in VS2003 and NUnit 2.2 for me. So I did a little bit of googling (now that this is a Dictionary term) and straight away found I’m joining a club. Some says NUnit 2.2.3 has fixed this. but I did not upgrade mine as yet. But I had another testing tool which is unlike Nunit is a Plug In ot the VS Enviorenment which is Test Driven .NET  which did not complain and worked perfectly. 

There was a comment at Darrell Norton’s Blog about being able to run tests directly from VS 2005. Not sure how……….need to find out. But until such time……………..its all TEST DRIVEN .NET for me.

Also find some tricks and workarounds people have tried before on the same issue here.

Today I became a member of the Yahoo group for Visual Studio .NET.

Good that there is such a group and would love to see what others are saying and doing.

Any Idea ………………….On how to be wealthy ……..the  ’Object Oriented’ way……………..

I’m getting a hang of all the issues related to code migration from VS2003 platform to VS2005 platform. It seems like my .dll files are going to work just fine. But I will have some playing to do when it comes to Server Controls such as the DataGrids. VS 2005 DataGrid has certainly undergone some modifications and this means some properties and methods of a DataGrid will be manipulated. So my VS 2003 DataGrid is a little alien to the new enviorenment. Hope other controls are just about fine in the new enviorenment.

To be honest, I feel as if I’m way back in early 2004 when I was putting all those long hours trying to figure out how ASP.NET 1.1 controls work. Now it’s my turn to learn ASP.NET 2.0 controls.

It’s back to the drawing board…………………………………
I heard someone saying ‘History Repeats’………………………………………………………………………………………cool.

Last Saturday, I was invited by one of my friends to attend a grand occasion, The Annual Japanese Summer Festival Celebrations in Colombo. I had no idea what it was going to be like till I arrived at the venue.
My first impression was that I’m in Tokyo,or some Japanese City. Japanese Men and Women in their traditional dresses were a treat to watch.

They were singing, dancing and enjoing the evening. The kids were quite playful and looked extremely cute in traditional Japanese dress. I also had a rare glimpse at Japanese Cuisine. I loved the Green Tea in particular. This occasion was Co Sponsered by Singapore Air Lines and Nihonbashi Japanese Restaurant in Sri-Lanka.

We have decided to start our development work with Visual Studio 2005 for the new project. I had to make some changes to my computer first. I had Windows XP SP1 and finally decided to just update it with SP2 even though I have previously experinced that my machine got slowed down after this update. Any way I have no choice but to go with it.
Upgrading with SP2 was quite time consuming and took me more than 1 hr.

I installed VS 2005 to my E drive since I also have my VS 2003 in another drive. I’m not sure whether this will have any problem in the future. Upto now all my projects done in VS2003 are working smoothly.
I must admit that the VS2005 setup was smooth, but I did not install MSDN for VS2005 due to lack of disk space.
We will be start development on this new platform from next week and we will introduce ATLAS controls into our application.

Should be some very interesting weeks ahead……………………………………………………………………….
