<p>I'm trying to create a very simple form in an Access database. Whenever I drag a textbox on the form, a label gets created with it. I want to be able to move the label without moving the textbox,but whenever I try to do that, the textbox moves with it. Its like they're linked with each other.

<p>I want to know how to make a mold of a 3D design in .stl format.</p>
<p>Suppose I have a 3D partin .stl format (for e.g. a cylinder) and I want to make/design a mold for this object (i.e. the structure through which I could make the cylinder). Is there any way to do so? Are there any tools to do so?</p>
<p>My requ... | <p>You can also bring the model and a big box into slic3r, align and orient them (enclose the model in the box), and do a subtract modifier, leaving a hollow where the two intersected. You probably want to do this twice, for a top mould and a botom mould. I've done this, but I don't see any instructions online for it. ... | <p>In addition to the answer of Davo (which describes a surprising feature of the slicer software I was unaware of), a more generic description would involve the use of a 3D solid model CAD program. You should be aware that a model in STL format is not a solid model, it is a surface model. In order to make a mold you w... | 894 |
<p>The "instruments" that are used with Guitar Hero and Rock Band have USB connections. Is there any documentation or reverse-engineering info out there about how to read the messages they generate?</p>
| <p>Check out <a href="http://www.wiiuse.net/?nav=docs" rel="nofollow noreferrer">Wiiuse</a> - it suppors the Guitar Hero 3 controller, as well as Wiimotes :)</p>
| <p>You could check <a href="http://fretsonfire.sourceforge.net/" rel="nofollow noreferrer">Frets on Fire</a> project. It's opensource GH-like game, and as far as I remember documentation said you could use Guitar Hero controller instead of the keyboard.</p>
