Greetings,
I am using Dreamweaver CS3 to design an ASP page that contains an Insert Record Form. Within this form are two list/menu form fields that I would like to "synchroniz e". In other words, let's say one list/menu is where the user selects "Program Name" and a second is for selecting "Project Name". If the user makes a selection from the first list/menu, then the second list/menu is requeried and "refreshed" to show only the project names for the selected program name.
I understand the problem with ASP being a server-side technology and that it ceases to work as soon as the page is loaded. I need some client-side scripting to make this work and I want to know how to do this with javascript because my efforts to refresh my page each time and send the parameters through a querystring haven't been very successful.
I can post code for what I have thus far should anyone want to see it, but thought I'd pose the question first to see if anyone has any advice or URL links/examples to point me toward.
Any advice or suggestions would be most welcome.
- JM

You have two choices. Either load all the options (in arrays) during page load and use them onchange, or whenever a change occurs, make an Ajax request to get the options for that particular project. Which one would you prefer or is more appropriate in your case?
The first one (loading options in arrays) is probably more appropriate given my limited java knowledge.

You should find this link useful.
Note that it's JavaScript, not Java.
Thanks for the link. Do you also have a link for the Ajax request option? I ask because if I run into issues with the JavaScript, it would be nice to have a backup plan.

Recognized Expert Moderator MVP Here's a quick general Ajax example. What you would do is change the ASP to return the options of the list. You can either return the HTML and just set a select object's innerHTML to the response or return a delimited which you can split to get the options.

I am having a strange problem. The program is a bit complex, but I'll try to
simplify what I can. I apologize if this is complicated, but I think this
would still be simpler than posting a bunch of source code. If you want me
to post code, though, just say so.
In a nutshell, I've got an ASP.NET application that has one main ASPX page.
On that ASPX page, it has a user control (an ASCX) that displays the actual
data and controls I need.

Hello, everyone.
Well, let me cut to the chase and explain my problem.
I am trying to devise a menu plan that uses the if/else if and the while loop. The program calculates the user's weight on a given planet. It first asks for the user's weight, asks them for a choice. If they choose choices 1 though 9, the user's weight will be calculated on whatever choice they picked (for example, if the user inputs 150 as their weight and choose...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
