Microsoft.Win32.RegistryKey s;
s=Microsoft.Win32.Registry.LocalMachine.OpenSubKey( @"Software\ODBC\ODBC.INI\ODBC Data Sources" );

// make sure we have a path there
if (s!=null)
{
string []xx = s.GetValueNames();
Label1.Text="";

// walk list

I use a form to display combos and edit boxes. I read all the details using javascript. I do NOT wish to submit the form ever, although when the user presses ENTER the default action is to POST the form. How can I stop this please? Confused | :confused:

in the form tag, put onSubmit="return false;", or just get rid of the form tag all together. If you are not submitting it, you dont need it.

Host headers & Referrer

I'm trying to do the following 2 things:
1. log the referrer.
I've tried the following, but get a object expected error.

Request.UrlReferrer.ToString();

Any ideas?

2. I have 2 domain names pointing to one site and I want to find out which is being requested. The URL would be www.one.com or www.two.com, but I'm not sure how to get this from the Request object.

Any code examples would be cool.

Cheers,
Simon

You may not always have a referrer, e.g. if the user types in the URL. In this case, the "UrlReferrer" property will probably be null;
Look at Request.ServerVariables.Item("SERVER_NAME"), which should contain either "www.one.com" or "www.two.com" depending on the domain;

Thanks for any help.

What would happen if you assigned an ID to both of the columns and then used the DOM to check the width after load of the page?

Try accessing the clientWidth property, instead of the width property.

When for example I've been filling in a form for my address, I've seen it where I select the country, and the state/county combo box auto fills will all the country states/countys.

Anyone know how I could do this please?

I have seen this on the Microsoft site and a few others.

Basically there are two ways; Server side or client side. Each has it's advantages and disadvantages.

Server Side

This way you submit the form onChange of the Country drop down list. The server then loads the State/County drop down list with all the States and Counties that match the selected Country.

The disadvantage is that this requires a server round trip and people with low-bandwidth will get irritated having to wait for the page to load just to select a state. The advantage over the client-side is that you don't have to pre-load all the possibilities into a JavaScript array. Also it is easier to code. It is also cross-browser compliant.

Client Side

This way you pre-load all the states and counties for all the countries into a JavaScript array on the client side. onChange of the Country drop down you just use DHTML to fill the State/County drop down list with the relevant entries.

The disadvantage is naturally that pre-loading all of those states/counties can be a serious page bloater. You could end up with hundres of kilobytes of unused records. The advantage is that it is quick and no server round trip is needed. This is however not cross-browser compatible without serious extra work.

Saying all of that the best option is not to offer an automatic State/County list but rather just use the standard text box and let the user fill it in. Less coding, no server roundtrips and no pre-loading. People will prefer it, especially on slow lines.

The only exception of course is an intranet where response time is not an issue. Use the JavaScript method then.

You can always validate the State/County that the person types in on the server-side onSubmit of the form if State/County data must be valid.

If you need code for either of the above two, I recommend Google. The JavaScript method has quite a bit.

Thanks. It thought that may be the two ways. I'll try server-side I think.

Everything out there talks about working with ASP.NET and how to do special things like graphics, database, XML, etc. However what is missing (IMO) is setup of a project. Seems a lot of the people I talk to just have a heck of a time writing your simplest ASP.NET application because of all the security settings with a C# implmenetation and such. Maybe we could have someone write an article "Getting started with ASP.NET". I'll write it as soon as I get my home server ASP.NET application working!
