Re: A look at ASP.NET MVC 4

I am so happy to see that a bug reported to MS that they have closed as "can't duplicate" happened to Scott Gu on stage in front of thousands of people and is recorded and posted here on Channel 9.

OH, actually they changed it to resolved... in VS 11. Wait what?! This bug is a major productivity issue.

https://connect.microsoft.com/VisualStudio/feedback/details/665418/some-keyboard-keys-stop-working

Please, someone that cares about the quality of VS 2010 get this back ported and released as a hot fix or patch. I can deal with VS being slow and hanging for seconds every now and then... but stopping to respond to the keyboard and mouse clicks is not acceptable.

My concern is about the security trace: is it possibile to trace the current user application name ?

Normally we connect application to SQL using a unique trusted connection (windows authentication), but we are interested to log all db changes along with the current logged (application) user; otherwise we know the db changes but not who made them.

With triggers we would do this by getting the user_name from sql and we could insert it into the audit tables. This works well as long as you have a two tier application with each user having thier own connection.

With 3-Tier or web apps you are unable to use the user_name since you are probably using a single user id or connection pooling. So, what we would do is add a field or fields to each table that the application would populate on each insert/update. This way the audit data could capture who made the change. For delete I guess you would have to get creative like not allowing record deletes and just setting a delete flag... or you could update the record with all blank/null values prior to deleting it.

I would assume that you could do a similar thing with CDC?

Re: Pablo Castro, Britt Johnston, Michael Pizzo: ADO.NET Entity Framework - One Year Later

pilotbob — Tue, 09 Oct 2007 19:26:32 GMT

MS had a web cast on this... can't remember if it was on EntityFW or on LINQ to SQL... but the [main] differences as it explained them:

Linq to SQL

1. Only suports SQL Server

2. One to one mapping from Table to Object (although the Linq to SQL designer does seem to have inheritence stuff in it... so I'm not sure if this is 100% true.)

EnityFramework

1. Provider based data model to support multiple back ends.

2. An object (entity) can be mapped to multiple tables.

This tells me I need to be using the EntityFramework. Item 1 doesn't bother me since all of my projects are SQL server. But, I want to do DDD and it doesn't look like Linq to SQL is really designed for that.

So, I still don't understand why we (Microsoft) have both projects. I think the Linq to SQL should be dropped and all resources should be invested in the EntityFramework. It has better design goals and is a superset of Linq to SQL.

First of all, fascinating project.

I do have a question though. Currently in VS 2008 Beta 2 there is a new item which is LINQ to SQL which creates a couple files including a mapping to the database which can be queried using LINQ. You also get a design surface that looks similar to the Entities Design Surface.

What are the differences between the two (ie, why do they both exist) and why would one use one or the other?

Excellent question. It seems like MS has been trying to give us an O/R Mapping type product/services since the Object Spaces annoucment. Since then it has been false start after false start. I remember that Italian guy doing a C9 demo on Object Spaces years ago... where did he go?

Now, it seems like you have two competing technologies that actually might ship. I see alot of overlap between the two and also each has some features the other doesn't have.

Do these two teams know about each other? Why not merge the projects and come up with a single, consistent set of libraries to solve the problem of moving data from relational to object model.

Also, is there an Object first design paradim that you can do. I understand why all of these demos reverse engineer a db... but, can I create an object model first and then have in create my schema for me?

The LINQ to SQL objects also have partial method hooks that allow you to add business rules/validations to them. Is there anything like that in the Entities? Are the entities designed to also be the DTO's or are the entities just a way to tell link how to shape the objects that are returned from queries.

Confused,

Re: : Continuous Integration with Team Build “Orcas”

pilotbob — Sun, 18 Mar 2007 15:54:40 GMT

Looks great... a few questions...

1. It looks like the build agent is actually a dummy/slave machine and it is actually the TFS that monitors checkins and when a build is needed it tells a build agent to run that build. Is this the case? If so, can you have a pool of build agents rather than specifiying a specific agent for a specific build?

2. The build status UI looked like it was passive... in other words you actually had to decide to look at the build status screen to see if one failed or whatever. Is there any type of notifications that just pop-up if a build fails... sort of like cctray? CCtray makes things so easy... you can basically ignore it but a quick glance without opening any UI dialog and you can tell the status via the Green-Yellow-Red indications.

3. Is there any labeling in source control that corresponds to a build? This could perhaps be used because a build is compiled as Debug for testing but then when we decide to release the build we want to actually rebuild from the same source to create a release/install package. Or, is this just part of the build project file itself? (Sorry we have worked with TFS build at all yet.)

4. How easy is it to add additional build steps like perhaps running FxCop or Simian or Fitnesse tests? Can the reports from those third party tools be integrated into the data warehouse?

Thanks.

Re: Windows Vista "Time Warp": Understanding Vista's Backup and Restore Technologies

pilotbob — Tue, 27 Feb 2007 04:15:21 GMT

Ok, I admit I am a little confused. Does this take snapshots are predefined intervals or does it version a file everytime it is saved? So, if I save my document at 10:00 AM... then make a change and save it at 10:10 AM do I get both versions? Or, is that considered one change because it was saved between snapshot intervals?

Also, any chance NTFS will support the recycle bin? It seems at this time (XP) it is a shell feature cause I only get files in the recycle bin if I delete using explorer? But, if I use command line or some other app those files aren't put in the recycle. I would love to see the recycle bin be a file system feature.

Re: Windows Vista: Ready for ReadyDrive

pilotbob — Fri, 29 Sep 2006 04:28:48 GMT

I don't understand why this would/should be limited to Vista... This seems like the caching should be controlled in the drive firmware rather than the OS.

I would expect that you will soon see the cache utilization built right into the drive firmware so you get the same benefits of a flash cached hard drive.

This is not much different from SQL servers cache. The main difference is that you are using non-volitile ram rather than dram... so on power off the cache remains and can be used for booting as well. But, Personally, I leave my PC on all the time, so boot up time isn't a big deal.

Re: Jason Zander on the WinFX to .NET FX 3.0 rename

pilotbob — Sat, 05 Aug 2006 20:54:53 GMT

Another small point. My understanding was that the name WinFx was used because it was the underlying API of windows Vista which would be built on top of WinFx.

It is apparent that this didn't happen. Se la vi.

Re: Jason Zander on the WinFX to .NET FX 3.0 rename

pilotbob — Sat, 05 Aug 2006 20:52:27 GMT

Jason,

Something that wasn't addressed that I kept expecting the intervier to ask is how the Visual Studio version relates to the NetFx version?

Currently, correct me if I am wrong, but if you want to target .NetFx1.0 app you MUST use VS.Net. If you want to target .NetFx 1.1 you MUST use VS.Net 2003.

Now that VS 2005 is out, it seems to allow you to target .NetFx 2.0 and 3.0. But, you can't target .NetFx 1.1 with VS 2005. (Yes, I know you can use BEE to compile from VS 2005 to 1.1, but there is nothing in the IDE to ensure that you only use/reference DLL's and features of the 1.1 framework.)

So, now you say NetFx 3.5 (for example) is the next "version" of the framework. Will I be able to target that with VS 2005? Or, will I be required to upgrade to VS.Next?

Also, will VS.Next be able to target .NetFx 3.0 and 2.0 as well as 3.5 while still giving me the new IDE features of VS.Next?

In other words, are there plans to decouple the VS (IDE) version from the framework version and allow tools in the IDE to target a specific .NetFx version?

I know sometimes the new IDE requires the new Fx version to run. That was the excuse as to why you can't use VS 2005 to target .NetFx 1.1 apps. But, it didn't make sense. I have no problem installing .NetFx 2.0 in order to get the VS 2005 features while still wanting to target 1.1 NetFx.

Can you tell I hate having to drop back to VS.Net 2003 to work on my .NetFx 1.1 apps. ???!

Looks very promising, what I object is that it's still data driven. You generate a new set of classes that abstract a database (which might be usefull), but why generate new classes if you already have your own set of the domain in question? I believe a coherent Model Driven solution should also exist and I guess with entities the true ORM nature should allow us to use our domain objects directly. At this point we can see a convergence between the approaches of both Java and .Net on persistence and object-relational mapping except that .Net integrates the queries directly in the language.

Sounds like you need to read the SQL Server manual. Since 7.0 there is no advantage to running a query that is in a stored proc over one that is sent via the connection.

As a matter of fact there can be a disatvantage in that the first time you run the stored proc, the execution plan is optimized for the specific parameters that you pass in. Your next call to that proc may have a faster execution plan but the existing one will be used since it is from a already run proc.

Also, dynamic query's execution plans are cached, so if the same query comes in again the previous execution plan is reused.

You may want to look at some of Kim Tripp's web casts on SQL performance optimization where she actually demonstrates that even using dynamic SQL in an SP can dramatically increase performance.

Re: ADO.NET Entity Framework: What. How. Why.

pilotbob — Sat, 05 Aug 2006 18:29:10 GMT

Well, it seems object spaces isn't dead afterall.

Anyway... do you see this framework simply as a DAL tier feature? Are the entities that are generated basically a container for metadata? Or, can the entities be used as business objects? In other words, can the entities contain business rules or are they more like data transfer objects (DTO's) that have no encapsulated code.

Re: Tim Sneath - Inside Windows Vista Printing

pilotbob — Mon, 21 Nov 2005 03:46:40 GMT

This stuff looks cool.

A question on the DRM and Digital Signature.

As a developer of a web based finanicals application two things we constantly get requests for...

1. Users want a direct to printer experience. The feeling is since the checks are printed and renedered to PDF on the server and send to the client, these PDFs can be saved and they are unsecure.

2. Users want a secure way to generate a "wet signature" on the check. Basically we are using Sig Cartaridge with a sig font on it. Some what better but still not 100% secure.

Will XPS solve these problems?

Can a MIME Type be set up so that a check run generated on the web server will be sent directly to the users printer? Or something?

Is there anyway an XPS document can be protected so that only a certain person, perhaps a person with that card you showed would be able to print the doc? It seemed that you demonstrated the reverse where the scanned doc would be digitally signed by the smart card?

I gotta say, you are halarious. One of the more entertaining presenters that I have seen on Channel9 thus far.

As far as tick marks in the scroll bar, ReSharper uses them to indicate "issues" that it finds in your code. If you hover over them you get a tool tip with the problem and can choose if/how you want them fixed. Not sure if they were the first to use them. Maybe they patented them?

I also agree with the others. The XSLT mapper would be a great add-in to the XML tools in Whidbey. Have you shown this stuff to Yag and Ken Levy?

Now, get back to work.
