So I was bored at lunch, and decided to write this. It's a base for a little program I am thinking of writing. I'll work on it when I get time.
I've attached the .exe in a .zip format. Below is the code, and it's not the best, nor the prettiest. It's kind of slow if you do a big list, but I can speed it up later.
I've updated the code to do use multitasking (No more GUI freezes) and minor performance increases. I've also added it to GitHub with the entire project files and the executable .exe. You can find it here https://github.com/Kyle-Undefined/GrandExchangeParser
It should have all the files needed to open it in your own Visual Studio, if not, let me know and I'll add them.
