I know I shouldn't have done this, but I did, and I wonder if it is a bug that anyone has heard about:
I created a new Web App. In the design view, I dragged an SqlAdapter and connection onto my aspx page, rather than creating a middle-tier component. VS added the appropriate member variables and added code to InitializeComponent() to set up the Sql objects. I got my app working fine.
After a while, my virtual memory usage creeps up and I'm swapping like a mad dog, so I save my app, exit VS, and restart the system. When I come back, the Sql objects no longer appear in design view, and the initialization code is gone from InitializeComponent(). However, the member variables are still there!
I fixed everthing, and got the app working. I save, exit and restart a number of times and everything is OK. Then, a day or so later, same problem!
Has anyone seen this?
Plus, when the Sql objects disappeared, another strange thing happened. Even thought I had code in my aspx.cs module for event handlers for my DataGrid, the event handlers weren't called. When I looked at the VS property sheet, my handlers weren't listed. Simply adding them into the property sheet fixed the problem, and they were called. Why is that? Shouldn't simply having them in the aspx.cs module make them work?
Thanks for any clues.

Are they COM objects? Or something else?
Thankx.

Quick answer here but I believe that they are the same thing. Windows relies on COM (now COM+) and as one sage remarked "Microsofts ace is COM, everything else they do is just fluff for their COM empire".
Naturally the word Components gets bandied about a lot. From my experience when they refer to Components in the VS.NET help and articles they simply are talking about the custom controls and components that come with VS.NET. You can naturally create your own Components for VS.NET and in most cases they will be COM+.

Is it possible to install VS .Net Beta 2 and VS6 on the same system.
|
|
|
|
|
Theoretically that shouldn't be a problem. Although there is no garanty that installing VS.NET Beta 2 will not affect your other apps so dramatically that not only VS6 but also your OS stops working properly.
At the moment VS.NET Beta 2 is in a very unstable stage.

I ran VS6 and VS.Net Beta 1 on my laptop with WIN2000 Prof for about three months without problems. I recently uninstalled the Beta 1, and installed Beta 2 Framework SDK, and have not noticed any problems with the rest of my applications.
You may need to be careful when you run the compilers to be sure you are pointing to the correct path, and that the correct CL is being invoked.

Yes but don't compile any production code with VB6 as some of the components will be pulled from .Net and installed on the client machine.

Over the next 6 to 12 months I have to write a whitepaper on .NET for my employer.
I would be grateful if anyone can point me at any useful resources, including criticisms, but especially anything to do with the expected benefits to business (broadly speaking we're a software house).

http://www.microsoft.com/net has info on this. Also, MSDN contains articles about .NET.
|
|
|
|
|
I was hoping for a little more than the obvious
|
|
|
|
|
There are some very good .NET related discussion groups archived at http://discuss.develop.com/archives/index.html
Plenty of details on the pros, cons and technical details of .NET
|
|
|
|
|
Thanks very much for the info. Not much to wade through, though
|
|
|
|

One of the better histories for .Net is in http://www.dnjonline.com/articles/essentials/iss24_essentials.html
Also - check through the archives of http://www.dotnetwire.com - there is an article about ".Net from a J2EE" perspective that is excellent.
I used these two resources and MSDN when I wrote a white paper for my company.

I am using Windows ME and want to get up to speed with ASP.NET. Is there any way to run ASP.NET on my platform? Should I try installing IIS for Win NT? Has anybody tried this?
'Get Win 2000' would be a really useful suggestion. But I cannot get Win 2K right now for several reasons...
|
|

|

There are sites out there that will allow you to build and play with ASP.NET without fees for those that cannot create a system in which to use ASP.NET of their own.
Just an alternative.
Cheers,
-Erik

I looked around on the web and found only one free ASP.NET provider - brinkster.com - but they do not offer ftp access so I have to upload each file through their web admin interface... Not really convinient for a large project. Anybody know of some other free ASP.NET provider?
