PHP Laravel – emptying database during seeding with foreign key constraints
It was little over a decade ago when I first began my developing career in some of the most basic of web-based projects. Back in those days, I was primarily based in web-development for a variety of projects including DW4N and a range of forums. In this challenge, PHP was my primary language of use,

C# adding reference error – Checking a C++ DLL is valid for a C# project
DLLs compatible with C# projects can either be managed or unmanaged. However, if they’re unmanaged, they cannot be included in the project using the standard References->Add Reference->Browse->OK method, as only managed DLLs can be added in .net applications in this method. To add unmanaged DLLs you need to use a form of DLLImport, which I

C# WPF – text box is not editable?
In my current work in the c#/WPF environment, I’ve had a need to create a new pop-out window with a load of text boxes and labels programmatically depending on a previous input.

Use images as button icons in Dynamo components
Dynamo is becoming a bit of a ‘thing’ in the office recently, with a shift in some technology focus as Dynamo and the rest of BIM begin to really take hold in industry. As such, some people are trying to get ahead of the game and make sure their Grasshopper components can also work in

NodeJS – how to install Socket.IO
This week my focus at work has shifted slightly away from Grasshopper and back into the world of web development, server communications and associated tasks. For part of my work, I created some test files to play about with sockets in Javascript (the bigger picture is to use sockets to communicate between some C# code

How to fix the ‘Common Language Runtime was unable to set the breakpoint’ error in Visual Studio projects
When you have multiple projects which link together, it can be handy to have them open in Visual Studio to debug through or work on them. This is especially true if you’re using libraries which contain common code across projects. That is the purpose of a DLL after all (or static library), to provide common

How to fix ‘type load exception’ when loading a Grasshopper component
As mentioned previously, I’ve been working in James’ territory on a Grasshopper component as part of my research. The tool is now ready for testing and as such, I gave copied of the .gha file and background .dll file to a colleague to test on their machine. However, instead of loading the component, Grasshopper threw

C++ Error LNK2005 – item already defined in file.obj
Linker errors (LNK) can be a bit more difficult to solve than standard C errors if you don’t know how to read the error output. This is added to by the fact that you can’t double-click the error and be taken to the line causing the problem (if using Visual Studio anyway), so being able
