You really can't. Not unless you store all your data as XML or you use Access, or something.

SQL Express is OK, but not good if it will be used by many people at once.

This sounds like a disaster. You want to expose your clients to this mess ? Get a real host. One with SQL Server.

Is it possible to attach SQL2005EXPRESS without SQL running on the host machine? If so how?

Of course not. If the database is not running on the host machine, or a machine visible to the host, then it's not going to work, is it ?

However, Access would be fine. You just need to work out what's holding the file open when your code tries to open it ( that's what that error is )

Christian,

Their sites aren't going to be hosted with my site, they have their own host so I wont be exposing them to anything. Like I said, this is a fairly simple "Extranet" that the client can log into and we can communicate back and forth with one another, they can upload documents to my site for me to use and so on, it is in no way connected to their site at all. Eventually we will (hopefully within the month) have SQL 2005 back up and running on the server I'm hosted on and this wont be a problem. The SQL Express wont be used by many people at once, maybe 5 -10 at a time for now, by the time it's more this wont be an issue as SQL 2005 will be on the server. I was just looking for a solution for the time being.

PS: I do have a real host, he has 13 Dell Blade Servers and a central server for running SQL (it's just not up and running as of yet). He is hosting several mission critical sites using SQL but his current SQL is Co-Hosted elsewhere and they wont let me connect via Enterprise Manager or Query Analyzer so I cant use their database server.

How to set the default page on asp.net

I want to set contact_us.aspx like the web site default page, but i cant reach the iis admin, can i do by another way?, maybe the web.config..

You normally would do it through the iis admin. There is a tab where you set the default page. If that is not an option you can do some http re-direction so when the default.aspx page is requested you could auto redirect. The easiest way to do this is to create a default.aspx page and in the page load event to a response.redirect("contact_us.aspx")

Hope that helps.

No, you need to tell IIS what page to load by default. You could just change your index.aspx, or whatever, to redirect to the page you want ? Or does the index page get used elsewhere ?

OK, an MDB file ? What if you recreate your table structure in SQL Server and try this SQL ? I presume the SQL is wrong, it looks odd to me. Do the two tables you're inserting from and to have the same fields in them ? Have you tried rewriting it to work differently ?

OK, your code is in fact in the code behind.

Yes, this will work, but it's not how to produce well written software. Your presentation code should call methods on a dll which contain your buisiness logic and database functionality. This if fine if you're writing something for fun, but if someone is paying for it, or it's going to be put to serious use, this is not how to go about it.

I am not a school'd programmer. Infact, this is the first Dot Net website, I have ever done. I am a VB programmer, my jon was eliminated and my company offered me this position. This is how all of the pages that were given to me function. Every piece of code we use in our code behind. I work for the GOVT, we arent allowed to USE SQL server yet!

OK, even in a client VB app, you should use an n-tiered approach.

Then your job is probably safe for now, but if you want to be employable in the 'real world', I recommend doing a google on n-tiered architecture and learning how to write this stuff.

I am not schooled either, but if you're self taught, all the more reason to always be looking for things to learn.

I know, that SQL has nothing to do with it. Smile | :)

Actually, I wasnt a VB.net programmer, just a VBScript programer did alot of excel / access programering, as well as I wrote alot of instrumentation programs the govt uses to analyze network packets that they collect with there High Speed Lan Taps. I know how to write true VB apps.

Why would you want to compile a whole websites piece of code into a DLL file? I will google it like you said, I am always looking to learn, but this project wasnt mind from the begining, I got given it after someone was working on it for two years, there is lots of devlopment done to it, and there is no way I could go back and change it all is what I was getting at.

Because that's how it is done - the business logic and data access exist in different assemblies to the presentation layer. In theory, it means different parts can be replaced. This does not happen in the real world. However, it does help with organising the code, nonetheless. Certainly having all the DB code in one place is invaluable. And, using stored procs is even better.

Well, you may be able to improve new parts at least. Or, at a minimum, learn how to do it, so you can tell your bosses that you're not happy having to work with a monolithic structure, that it will cause maintenance issues in the future, but you have no choice.
