  - by Steve

  I'm using the ASP.NET Ajax toolkit. In addition to the AjaxControlToolkit.dll in my bin directory, I have language directories named es, de, fr, etc... The single file, the AjaxControlToolkit.resources.dll disappears from these directories every once in a while - I can't figure out why. I manually copy them back, but I've purposely done rebuild and clean solutions and they are still there. Somewhere during my normal course of work, when I'm not looking, they're gone. Any clues?

• perl: tk: a way/widget that allows pixel level control over the output

  - by chhh

  I want something like a canvas, but where i'd be able to manipulate pixels easily in addition to all the provided geometries, that can be drawn on canvas. Is it possible to embed something like GD::Image into a canvas? So then I maybe could make the image transparent and set some pixels in it (GD::Image-setPixel()) positioning it over the canvas? ps: well, that doesn't necessarily have to be perl, as there seem to be bindings for all the libs for most scripting (and not only) languages.
