There is also … Read more
There was a question on Stackoverflow about a C++ project displaying an image as you type. Here is the original question: I am writing a very simple program in C++ that listens to keyboard input, but what I want to output is much more difficult than I expected.

Last year I posted a small MFC application on my blog, called Colors Game, about covering with a single color a grid initially colored in six colors. It wasn’t a big deal of an application, but it was fun and recently I decided to write a WPF version of that MFC game. This is the … Read more
