The Linkage program is written in C++ using the Microsoft Foundation Classes (MFC). MFC provides C++ classes for things like strings, but also provides a document-view architecture. The idea behind the document-view architecture is that your document is the information that needs to be displayed and the view…
Continue readingCam and Follower I was able to get a functioning cam simulation running in JavaScript. It was a little tricky and isn’t quite perfect yet. Mostly, I had to remember how my code works with the HTML5 canvas and with the coordinate system that I use for the…
Continue readingI am writing software to simulate the operation of a cam and follower. I’ll add this to the Linkage program as soon as the details are worked out and the code is known to work right. The first type of cam I want to use is a typical…
Continue readingI updated the code for the circular progress ring (seen in the picture below). You can download a complete VS project for it here: http://www.rectorsquid.com/CircleprogressRing.zip Three Progress Rings
Continue readingNo Single Predicable Connector The image above represents a mechanism that the Linkage program cannot simulate. The simulator code only looks for predictable connector positions and there are none in this mechanism. Let me explain: The simulator will look for two links that each have a connector with…
Continue readingI have a new part built for the new Rolling Ball Sculpture. Small Ball Lifter The small lifter part is the lowest lifting arm on the mechanism. This part lifts the ball off the frame to a position where another arm can take the ball. The ball is…
Continue readingThe PriorityStackPanel class is a Panel element that I built for my Windows Store app. The idea is that the panel should adapt the content to the display based on a set of rules. The existing panels in C# and WinRT are totally useless for this task because…
Continue readingI have only used this horizontally. This panel will shrink down to zero size if needed, which might not be what you expect. The important parts of the code are commented. This is my first attempt at this particular feature and the code may be incomplete. I have…
Continue readingI recently wrote about a sort of StackPanel that I needed to write that would never show partial content if there was not enough room for that content. Well, I was about to write a new post with the code for it, which is working as well as…
Continue readingI’m writing a Windows Store app, as many previous posts have made obvious, and I’ve got a new need that might not be fulfilled by any Microsoft tools. I need a StackPanel that hides any children that can’t be shown in their requested size. My plan is to…
