Making a standard ASP.NET listbox do multiselect without holding Ctrl

-
I've always hated that users of a standard ASP.NET listbox control must hold ctrl to select multiple items. It's just a recipe for bad/incomplete data input. So, I set out to see if I could make the listbox do multiselect without holding the ctrl key. I know that there are third party controls out there that accomplish this more elegantly, but I wanted to see if it was possible with a standard control. I managed to get it going with some javascript help.

First, I defined my listbox & gave it an onclick event to fire a javascript method:

Second, I created the javascript method (the last one below) to loop through the listbox elements, select all of the items previously selected, and toggle the one the user clicked.
//This array holds the "selected" state of each listbox item var selectedClientPermissions = []; //Because I'm working with a databound listbox, I grab the selected values //on page load & put them in the array. function pageLoad() { var…

"On Show" script substitute for ArchestrA graphics

-
While developing a control screen using ArchestrA graphics, I found that the "On Show" script provided for graphics is flaky at best. This is especially apparent when referencing dynamically referenced objects in the script. In this case, the graphic can be used by several different objects. In order to allow it to get it's bearings on startup, it is embedded in another graphic. That graphic has a "while showing" script with a statement something like this:

MyGraphic.OwningObject = InTouch:MemoryNodeID + "some other text to dynamically build the object name";

This allows me to use "Me.WhateverUDA" type references in my graphic to interact with the object assigned as "OwningObject" above. The problem is that any "Me.WhateverUDA"-type statements I put in the "On Show" script don't work because of timing issues. The "On Show script apparently fires before the "OwningObject" statement above.…

Dynamic Object Oriented programming in ArchestrA

-
As with most developers using Wonderware products, I often have to get creative to compensate for the limitations in the development platform, scripting language, etc. Lately, I've been need to create "objects" (in the object oriented programming sense of the word, not the app server sense). That is I need collections of data describing some real world thing.

For example, I have been creating a callout feature for a client's SCADA host system. The callouts are stored in a SQL database and my scripts pull out a whole set at a time. Each callout has various attributes such as the callout type, the comparison operator (>, <, =, >=, <=), the setpoint, etc. This presents two issues. First, how do I keep all of these pieces of information together for each callout without creating & deploying App Server objects for each one. Second, at any given time, there will be a variable number of callouts.

I have used the following method (read complete hack) t…
