❔ How to use DLL?

Hi guys, so i am trying to make a console application and need to use some functionality in these dll's. I use those residing in the bin folder. i have tried to import nistmsclp_2gb.dll however i get an ": 'Could not load file or assembly 'nistmsclp_2gb.dll' or one of its dependencies" when i try to use some functionality. So this leads me to think that i need to import other dll's beside this wrapper dll, i however get an error "please make sure that the file is accessible and that it is a valid assembly or com component" when i try to import the native libraries whether it's x86 or x64. Any idea how to go about this? Thanks! I have included some documentation below.

Is it an open source / public library?

Ertan KöseOP•2y ago

yes kind of it's a NIST library

Monsieur Wholesome•2y ago

I'd like to try it out myself, do you have a link? Hmm, a direct download link? Youve got a link to a site perhaps?

Ertan KöseOP•2y ago

Nope sorry, it looks sketch i know but it's safe lol

Monsieur Wholesome•2y ago

e

Jimmacle•2y ago

i mean, it's the legit nist site

Ertan KöseOP•2y ago

Exactly

Jimmacle•2y ago

not saying everyone should just download it, but it's better than some random domain

Ertan KöseOP•2y ago

I just need to use it to use their search function

Monsieur Wholesome•2y ago

What does your code look like?

Ertan KöseOP•2y ago

Monsieur Wholesome•2y ago

Within your project, create a folder called something like "deps" or "dependencies" Or maybe even smth like "native"

Monsieur Wholesome•2y ago

And copy those in there

Jimmacle•2y ago

could be that the DLLs are referenced but aren't being copied to the build directory

Monsieur Wholesome•2y ago

And then change all the .dll properties in the solution explorer to "copy if newer"

Monsieur Wholesome•2y ago

Then try again their sample csharp app has a 4k loc program.cs lol

Jimmacle•2y ago

rip scientists aren't known for pretty code

Monsieur Wholesome•2y ago

hence python is popular

Ertan KöseOP•2y ago

i swear and their documentation isn't exactly user friendly lol but im on it!

Monsieur Wholesome•2y ago

you got this does this work for you @Ertan Köse ? I lied btw, their source code for Program.cs is a bit above 6k loc

Ertan KöseOP•2y ago

i was getting some snack doing it now 🙂

Monsieur Wholesome•2y ago

tis gon be a long night

Ertan KöseOP•2y ago

Ok so unfortunately same error, i loaded them in as you said and change it to copy if newer

Monsieur Wholesome•2y ago

hm

Ertan KöseOP•2y ago

btw thank you i appreciate it!

Monsieur Wholesome•2y ago

urgh, i hate this It does work, it's just that it copies it into a deps sub folder output >.> One sec, imma look for a proper copying solution Open your .csproj file, and drop the following in there

    <ItemGroup>
        <None Update="deps\ctnt66_64.dll">
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>

Okey on it

Ertan KöseOP•2y ago

Okey same error but here is the thing the build action is set to content in the dll's do i perhaps need to change this maybe to embedded ressource, and do i still need the reference?

Ertan KöseOP•2y ago

Did you get it to work?

Monsieur Wholesome•2y ago

Yes, I did Nah, keep it as is

Monsieur Wholesome•2y ago

works for me

Monsieur Wholesome•2y ago

Ertan KöseOP•2y ago

Monsieur Wholesome•2y ago

ConsoleApp20.zip

Ertan KöseOP•2y ago

Ertan KöseOP•2y ago

Hahah man i don't know any better what sdk version are you on?

Monsieur Wholesome•2y ago

Ertan KöseOP•2y ago

omg

Monsieur Wholesome•2y ago

$newproject

When creating a new project, prefer using .NET over .NET Framework, unless you have a very specific reason to be using .NET Framework. .NET Framework is now legacy code and only get security fix updates, it no longer gets new features and is not recommended. https://cdn.discordapp.com/attachments/569261465463160900/899381236617855016/unknown.png

Ertan KöseOP•2y ago

Monsieur Wholesome•2y ago

what kinda stuff

Ertan KöseOP•2y ago

Not the language c# itself but more .net itself i guess any book would do

Monsieur Wholesome•2y ago

Ertan KöseOP•2y ago

Actually true

Ertan KöseOP•2y ago
