- by Jake
Hi, for some reason I can't get my tableview to enter editing mode. It's a little harder than it might seem because I'm using some open source code to make a calendar (iCal esque) with a tableview under it, and it's not quite as straightforward as just using a regular tableview. Basically, I have two classes. One (let's say Class…Read the article

I'm trying to use reflection to automatically test that all my linq2sql entities match the test database.

Function to get X, Y position of an object orbiting a point, given a distance and angle in radians?
- by Jake Petroules
I am trying to code a function for a camera that orbits a point. Assume a 3d coordinate plane where Z is up. Ignore Z. Let's say the camera's position starts at (0, 0, z). The object to orbit is at, say (50, 50, z). So we have a distance of ~70 units. Calling the function with {(50, 50, z), 70, x} where x is the…Read the article
