Creating a HSL library that uses a C# .NET .dll class library

Hi Everyone,

I know that there have been some posts about this topic previously and that Eric has shared what resources he has on the topic.

I’ve done my best to follow the instructions in those resources, however the instructions are incomplete are presume a level of knowledge that I don’t have.

Would anyone that already knows how to do this be able to produce a really simple set of a example files please to demonstrate how the pieces fit together and interact? Perhaps a dll with a function that adds two integers together and returns the result? And a hsl file that instantiates that dll and has a function that accepts two integers from Method Editor, passes them to the dll function and then returns the result to Method Editor?

I have written a C# .NET app which can reformat an Excel file ready for printing and which exports that Excel file as a PDF, however the application has grown to be a multi function application and I’d like to build it into a fully fledged hsl library. I think I understand all of the pieces needed, however I just can’t figure out how to fit them together. I’ve tried to reverse engineer existing libraries but of course you can’t see inside the dll files to see how that part works and which function names relate to which parts in C#. Forgive me for no doubt getting my nomenclature completely wrong here.

Grateful for any help offered!
Will

Did you find this guide: Accessing C++ standard library in HSL? - #5 by zachary.milot? This is as thorough an explanation as you could need. Is there any specific question you have?

Hi @Stefan

I didn’t find it in my initial searches but I found it this morning. I’ve just finished testing it out and it works beautifully. It was exactly what I was after. I was on my way here to post a huge link to zachary’s post and apologise for not looking properly in the first instance.

Many thanks @Stefan and HUGE thanks to @zachary.milot
