Programmaticall y Select Option

J1C
If I only know the value of an option is a select list, is it possible
to programmaticall y select that option?

I would be returning the value from a server-side script ...

How are you returning it? If you're sending the whole page,
just give that option tag the SELECTED attribute.

Loop through the options in the select. When you find one with the
required value, set its selected property to true.
function selectOpt( f, s, v ){
var opts = document.forms[f].elements[s].options;
var o, i = opts.length;
while ( ( o == opts[--i] ) ) {
if ( o.value == v ) {
o.selected = true;
return;
}
}
}

If it's a multiple select, drop the return.

Is it possible to modify the file properties of a file programmatically? For example, every file, when you right click has a properties option, then from that you can select the summary tab and from that set the Title, Author and Subject. I use c# and VB but can't find a way how to set these programmatically. Any one have any idea how to do this? Thanks - Keith.

Ok, so I'm creating a form on the fly. I can create the option group, I can create the checkboxes, but I can't figure out how to bind them to the option group I'm creating them within.

As it stands now I create the option group and bind it to a field in a table, then create the checkboxes inside the option group. After that,...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
