It’s all about COM component that scrabbles given string and insert the results into oracle DB. That component is working for a 6 month but for time to time the results that stored in the DB found corrupted when tried to re-scrabble by other application. The guys that wrote that component try to find out what the reason for this unexpected behavior without any success they saw that they writing ASCII values to the DB but for some reason the values that saved in DB didn’t match the send values. Further study found out that the oracle driver – ORAOLEDB, for some reason, don’t like values between 0xC0 – 0xCD and always replaces them with 0x63. The only workaround that we found is to use Microsoft provider MSDAORA. MSDAORA doesn’t seem to have this problem.

I come across this site http://www.dofactory.com/Patterns/Patterns.aspx. they got short explanation of each design pattern, UML diagram and real life sample code written in C#. I think its pretty useful site.

The last Microsoft PDC in LA, California revealed a series of new codenames for the evolving OS and projects of Microsoft.. My goal in this article is to generally describe these codenamed and these forming products.

It's the second time I see this behavior so I thing it worth publishing. Well all of the sudden using Installutil on service failed with an error about the Reflection, that don’t find any Installer type in assembly. This service already installed several times with Installutil without any problem so it's obvious (and I check it) that my assembly contain installer type. It's cleat that the service not already installed as service.

Today I play with “Windows Client Printer Driver”. This printer come with longhorn but you need to explicitly set it to be install or to use add windows component to install it. The printer can be use from win32 or Avalon programs and produce Avalon fixed-format document. To check it up I create word document with images embedded into the text and choose Windows Client Printer Driver as the active printer. The result was Avalon container that displays the text and graphics, exactly as I place them on the word document with all the benefits that Avalon supply. Nice J

Application recycling is common issue in the newsgroups. Most of the time programmers notice that the session lost due to application recycling but some times just application restart noticed. There are many causes to application recycle, the most common are:

Just finish today custom control that use GDI+ to show link analysis outcome in several visualization forms (circle, segmentation, hierarchic, etc'). We need to show about 1000 nodes * 1000 links and all the commercial tools that we check (such as tom sawyer) failed to do it in less then 2 second. Eventually we found out that using GDI+ result in sufficient response time. Yes, its enterprise application and all the clients got .Net framework installed on them.

Internet explorer from version 5+ can recognize GZIP encoding streams, open them and render the "unziped" HTML. So if all of your clients use just IE 5+ you can take advantage of this ability to reduce network traffic. This practice is very usable for national spread organization that include sites with low bandwidth lines (GZIP can reduce stream size up to 10 times). To use this ability you need to ZIP all streams  leaving your IIS server. HttpModules save our day by enable us to track down every outgoing response. Ben Lowery (our hero) create HTTPModule that Zip every outgoing request from the server. You can download the module with source code, explanations and sample from Bens site :  http://www.blowery.org/code/HttpCompressionModule_1.1.zip
