For the new project that I'm starting (that will only be deployed on WS2008), I'd prefer to use the new API of course...
I really hope something is available for managed code?

(Preferably with some VB.NET code.)

Is there a class in the .NET framework 3.0 / 3.5 to program against the task scheduler?

A lot of applications need some sort of scheduling, and it seems to me that it would be better to use the robust and extensive framework that the OS offers for this, instead of trying to roll your own.

I developed a very simple webservice, just one webmethod that returns a datatable.

Then, in my ASP.NET 2.0 website, I added a web reference to this webservice, and used the ObjectDataSource to databind the results to a DataList. 
So far so good, everything works like a charm on my dev machine.

BUT when I put this website online, it doesn't work anymore!!!

When using Eval("FileName") in the DataList I get the following error:

System.Web.HttpException: DataBinding: 'Webmedia.GetImagesResponseGetImagesResult' does not contain a property with the name 'FileName'.

Webmedia is just the name I gave to the web reference, and GetImages is the name of the Webmethod that I call in the Webservice.
FileName is one of the fields in the DataTable that the webservice function returns.

When using Container.DataItem("FileName") the error changes to:

System.MissingMemberException: No default member found for type 'GetImagesResponseGetImagesResult'.


Again, no matter which technique I use, it works perfectly when I run the website on my local Windows 2003 server.
(it doesn't matter whether I run the webservice online or locally as well, it works both ways)
Only when I run the website from the server on the Internet, I get the above server errors!
I even tried on 2 different hosting servers to be sure it isn't related to the webserver itself...

Anyone please have a clue what is happening here?

Thanks!!!

Unfortunately, no, and even now, 2 years later, only this post shows up when doing a web search for NAPTR on Windows DNS!

I completely forgot that I asked this same question back then already, and still have the same problem today!

Nowadays, NAPTR records are needed A LOT, and still, Microsoft didn't release an update to make their DNS support it... I'm baffled.

I really hope that this message catches the attention of someone at Microsoft, and that they can forward this question to the windows team?

Is it finally supported in Windows 2008 Server?
I can't fire up a VPC right now, so can someone running Longhorn beta3 please have a look?

That is fantastic! Thank you so much, you really saved my day Smiley

I just implemented your solution in my application, and it works flawlessly!

I was messing aroung with strings and a custom generic tree class.
Needless to say, using XmlDocument with SelectSingleNode is so much neater, I guess I really have to learn XPath some day (still haven't got the time to delve into that stuff).

In VS2008 you also have the new XDocument / XElement / etc... classes, would these give me any specific benefits?

What would be a quick and efficient way to accomplish this?

Any help with code (VB.NET or C#) would be greatly appreciated!

Ubuntu! Ubuntu! While the underlying OS of Ubuntu is solid, it's desktop / windowing system is crap.  And it looks very unfinished as well (maybe that's an understatement, design people call it plain ugly).

Ubuntu has a LOOOONG way to go if they want to target the desktop market...

Problem is, they're playing catch-up all the time, and history should have learned them that playing catch-up with Microsoft is a very bad idea / waste of time.

I think they should forget the whole desktop thing and focus on server and embedded applications.

That's logical.
You should install the express edition, Vista is a desktop and not a server OS after all!
Sql Server (except dev edition) didn't run on XP as well.
SQL server express is perfectly fine for development and you can still run a VPC image if you really need to do testing with the full blown server.

One of the fixes for this in 32 bit is to right click on the start menu in al programs and click "sort by name".  Does this still  work in vista, because it doesn't have a fly out menu like XP.

I tried that trick in all possible ways, but it simply doesn't work on Windows 2003 Server...
The only solution is to log off and on again, but as I have more than 20 windows opened at all time, that simply isn't doable.

Anyway, the whole point is that they released a new SP and didn't care to fix this bug!, although people from all over the world asked (even begged) for it in all possible ways.

Therefore, I'd like to know from someone on the windows team why it was impossible or why they didn't care to fix this extremely annoying bug.

You know, VB.NET has quite a few features that are missing in C#, so it all equals out at the end...

You shouldn't worry too much about which language to use, if you started with vb.net just continue with it, it's a great language for rapid development of business apps and asp.net websites.

I think that is still used quite a lot, and it gives very high quality results (better than Yahoo in my tests).

Also Alltheweb.com does a nice job with integration of sound and video search.
