I wanted to add a tooltip to an individual checkbox in a checkboxlist so that when someone did a mouseover on an individual checkbox, a little textbox pops up. I tried enumerating the control collection of the CheckBoxList control itself, but for some reason I only found one control (a checkbox) as a child control - I don't understand that yet...anyway....

    The solution is to enumerate the .Items collection of the CheckboxList and set/get each ListItem's attributes list through the .Attributes() method like thus:

        Protected Sub CheckBoxList1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBoxList1.PreRender
            For Each item As ListItem In Me.CheckBoxList1.Items
                item.Attributes.Add("title", "Hello World!")
            Next
            Return
        End Sub

    The end result a tooltip for each checkbox in the checkboxlist, so this .Attributes() method equates to setting/getting properties on the HTML elements themselves.

Nonetheless, checkout my new couch - it's got, what's called, a "snuggler" on the left-hand side there....that's for all the "snuggling" I do between working my ass off...

    ...I just understood why a particular trick I use works in terms of call-waiting: okay...when you are on a phone that doesn't have a Link option (to transfer from one line to another) and you have another person ring-in, you know how you can QUICKLY hang up the phone and then lift up off the hook switch and get the person on the other line? The "command" to tell the Central Office to switch lines for you is actually a signal from the hook switch lasting between 200 and 1,200 ms (from roughly one fifth a second to a second and a quarter) - so if you punch the Link button your phone, you're, in effect - spoofing a hang up for roughly that amount of time...

    ....the reason this works is because the hook switch is a signalling device to the central office (when you lift up, the CO knows to send you the dial-tone, and when you push down, it tells the CO to "hang up"). Commands via the hook switch are time-based.

    A new fascination is starting to pick up with me - digital telephony, or what some people may have heard as Voice over IP (or VoIP). My contracting company did some work for a company in southern California that optimizes network traffic and wanted to extend their service to VoIP; and ever since then I've known about the technology and knew I had an interest in it, but never really started researching it in the broader sense until now (you know how it is, someone presents you with a particular problem and you solve it, but you can still totally miss the big picture). I'm learning everything I can about the field at the moment, going into "chew mode" - chewing up as much information as possible. As a side-effect, I'm adding a new category to this blog to specifically address this fascination....
