Upload files via FTP with C#
Prior to going to India, I was looking at using sockets to send data between C# applications and web servers. While the work was interesting and a good insight into the use of NodeJS and various other pieces of the technology, it was unfortunately unable to achieve the task I had been set. This was

Quickly obtain every file name in a directory with C#
A quick post today showing how we can obtain the file name for every file in a given directory using C#. This might be useful for any kit where reading every file, or every kind of file in a directory is needed – e.g. reading in various data files. In this weeks research work, I

How to stop a Grasshopper component in the middle of calculations
Moving away from the recent work in NodeJS back to Grasshopper has brought me onto a sore point with the majority of calculations I try to perform. Most of my work requires some intense spatial analysis but can take a rather long time to complete. Sometimes I connect incorrect data by mistake and calculations try

How to use sockets to send data from a C# application to a server/webpage
Continuing the current them of working with NodeJS and sockets before I go on holiday for a couple of weeks, this post is going to look at how we can send data from a C# application to a server/webpage using Javascript and NodeJS. Previously in this theme we’ve looked at using NodeJS and Socket.IO to

Using sockets to communicate between Javascript and C# with NodeJS
Previously, we looked at how to create a simple chat application between two web clients using NodeJS and sockets. Those that know me however, know that web development is not my preferred role anymore (not since the days of DW4N, MP101 and my pet project Lobo Malo anyway), so the work in Javascript and NodeJS

Simple chat application with NodeJS and Socket.IO
This week has been about playing with sockets for some data communication between C# and Javascript. While getting to grips with the basics of the socket libraries, I created a simple chat application to run on my local machine. It served well as a basic introduction to sockets and the NodeJS package, so I thought

How to prevent multiple instances of a Grasshopper component being added to the canvas
Grasshopper components typically have the ability to be added to the canvas multiple times to allow different calculations to be performed depending on what it is your Grasshopper document is doing. However, there may occasionally be a need for your component to only be allowed on the canvas once. There could be many reasons for

How to stop specific outputs of a Grasshopper component from displaying results automatically
In this previous post, a way to stop a component from automatically displaying results on calculation was shown. This put the onus of previewing results directly onto the user. However, there may be a time when you wish for the user to view some results, but not all of them. For example, maybe you have

How to obtain minimum and maximum values from lists in Grasshopper – Version 2
In this previous post I showed the ways in which we can obtain the minimum and maximum values from lists of numbers in Grasshopper. I presented three solutions, using native Grasshopper components (with unintuitive naming), building your own using a C# script, or using a component which I offered for download. Since then, I found

How to add custom User Data to Rhino Objects
Objects in Rhino (the 3D modelling software, not the organs of the animal) have the option to attach custom user data that you may wish to share across tools. This might be of particular use in Grasshopper, enabling you to send one piece of geometry down the wires with custom data attached, rather than having
