In this web page:
http://www.microsoft.com/sql/editions/sqlmobile/sqlmobile.mspx

there's a link to "How to Buy SQL Server Mobile".

That page has a table with prices for various SQL Server editions.
Also the free Express edition is shown, but Mobile edition is missing !

Anyone has correct info about this subject ?

Tech Off - Developing Parts for Vista's sidebar: how to create .part files ?

if i remember correctly it's really just a compresssed file so if u compress it and rename the extension to .part that will be fine.

Extract a pre-existing .part file to see what other files u need for gadgets to function.

Thank you for this info.

Renamed to .zip and extracted all files.

There are 2 .xml files, 2 .js files and some .png files.

Also found more info in Channel 9 at this url:

Windows Vista Sidebar and Gadgets
http://channel9.msdn.com/Showpost.aspx?postid=128231

there's a 42 minutes video about building gadgets (AKA Parts) for Vista's sidebar

i'll watch it just now. I'm curious about the possibility to write more complex Parts using Visual Studio 2005 (DLLs ?).

Coffeehouse - 3-D Code Tools

We are using CAST to analyze our sources and prepare impact analysis when we receive change requests from users.

Take a look at their web site : http://www.castsoftware.com/

Their product is available for many programming languages and databases. YES, it's not a 3D interface, but if you want to quickly get a graph of an application or of a web site... well I think it's an extremely good tool.

Coffeehouse - Did you ever have the need of "queuing" SQL Jobs execution?

Mario Cannistrà — Wed, 26 Oct 2005 09:14:47 GMT

Thank you for your kind answer.

Last night i printed the article from Technet magazine. I will soon have some more time to read it with more attention. I've just read the introduction and the approach seems very close to my idea.

I'm not sure that every requirement is matched by that solution but i will post a complete feedback asap.

I've installed SQL Server 2005 and tried many new features. The Service Broker was still... queued.

Unfortunately, i've seen Technet magazine advertised on MSDN Magazine but it is not available outside US. Now that i know its available online, i'll take a look at it at least one time each week.

I've almost finished a solution based on SQL Jobs and that article could have brought me to a different approach. I'll let you know about this when i'll reach the bottom of the article.

About Async calls : i'll search info about this, but i suppose that the application must be left open to wait for the call completion.

This does not match the requirements because the users want to have more freedom (must be possible to close the app and take away the laptop for external activities).

Coffeehouse - Did you ever have the need of "queuing" SQL Jobs execution?

Mario Cannistrà — Tue, 25 Oct 2005 13:45:43 GMT

I recently met this problem and received disaccording answers from different information sources.

I have many users using an old client-server application to launch long-running procedures. They run for a minimum of 15 minutes to 60 minutes or more.

The procedures’ inner workings have already been examined from senior developers and from the DBA: no more optimizations are feasible.

Due to the high demand of processing and to the resource contention on the main database, I think that these activities should be queued.

The approach I’m suggesting is:

group all data processing routines in one or more stored procedures
modify the client application to “request” processing instead of directly executing it and receiving a job number
manage a queue of SQL jobs launched from a Windows Service
modify the client application to get the status of the user’s jobs
organize jobs in “classes” with different characteristics (maximum run time for the job, start and stop hour of day in which execution is allowed,…)

What is your opinion about this solution?

I think this approach could solve this specific problem and represent the framework to be used for projects with similar needs.

I look forward to read your comments.
