To be honest I don't know javascript well enough to say that something could or couldn't be done at all. Indeed, the
image filtersI mention can be applied in the css.
But seeing as the gadgets are rendered in essentially an Internet Explorer window, I don't see any reason in this particular case not to take advantage of vbscript. If ActiveX components become at all common in gadgets, for example, it may just be easier to use vbscript.
I meant my main point to be that vbscript is
designed to work well with Windows OS and Internet Explorer, while javascript has more universal uses. Since Sidebar gadgets are running in Explorer on Windows, vbscript would seem to me the logical choice for gadgets meant to be restricted to the desktop.
But, both do work, and perhaps my bias is just from a greater familiarity with vbscript. I don't know of anything off hand that simply can't be done in javascript, but in that light, other things being equal, I'll take the language developed specifically for the platform I am scripting for--Windows!
