WinForm Barcode Reader with Webcam and C#

WinForm Barcode Reader with Webcam and C#
Views: 4
When building a .NET application to read barcodes on Windows via camera, you need two types of SDKs – one for webcam, and the other for barcodes. In this post, I want to share how to use .Net webcam and barcode SDKs to create a simple WinForm barcode reader application in C#.

Algorithm Implementation/Strings/Longest common substring

Algorithm Implementation/Strings/Longest common substring Icon
Note to reader: It is unavoidable for this algorithm that O(nm) time is used, but all of these implementations also use O(nm) storage. The astute reader will notice that only the previous column of the grid storing the dynamic state is ever actually used in computing the next column. Thus, these algorithm can be altered to have only an O(n) storage requirement. By reassigning array references between two 1D arrays, this can be done without copying the state data from one array to another. I may return later and update this page accordingly; for now, this optimization is left as an exercise to the reader.

Understanding and Implementing Singleton Pattern in C# Icon
This article is yet another explanation and implementation of singleton pattern. We will look at what is singleton pattern is and how to implement it in C#. This is no way the best and recommended way of implementing singleton pattern in C#. the main idea for this article is just to present the concept of singleton pattern to the reader.
