VBS Functions
The lack of a decent GUI for VBS development has always been a problem for most people. The advantages of using VBS are great, but writing the scripts can be labourious, especially if you don’t have a lot of experience and know all the commands/functions etc. Nowadays, there are plenty of 3rd-party development environments available now, in fact, I use the excellent VBSEdit as it has code completion and comes with a whole load of code snippets covering all sorts of areas. The code completion feature is super helpful, especially when trying to remember the syntax of a particular function.
For reference purposes, I have included below a list of all the VBS functions as I am always looking up this information, so I thought I’d post it here so that it is more accessible to everyone (including me).

These functions are built-in to VBS so all you need to do is pass the correct values! I can’t remember where I sourced all of this information from, so if you want to be credited, just let me know!
