❔ 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 Köse•15mo ago

yes kind of it's a NIST library

Monsieur Wholesome•15mo 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 Köse•15mo ago

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

Monsieur Wholesome•15mo ago

e

Jimmacle•15mo ago

i mean, it's the legit nist site

Ertan Köse•15mo ago

Exactly

Jimmacle•15mo ago

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

Ertan Köse•15mo ago

I just need to use it to use their search function

Monsieur Wholesome•15mo ago

What does your code look like?

Ertan Köse•15mo ago

Monsieur Wholesome•15mo ago

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

Monsieur Wholesome•15mo ago

And copy those in there

Jimmacle•15mo ago

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

Monsieur Wholesome•15mo ago

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

Monsieur Wholesome•15mo ago

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

Jimmacle•15mo ago

rip scientists aren't known for pretty code

Monsieur Wholesome•15mo ago

hence python is popular

Ertan Köse•15mo ago

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

Monsieur Wholesome•15mo 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 Köse•15mo ago

i was getting some snack doing it now 🙂

Monsieur Wholesome•15mo ago

tis gon be a long night

Ertan Köse•15mo ago

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

Monsieur Wholesome•15mo ago

hm

Ertan Köse•15mo ago

btw thank you i appreciate it!

Monsieur Wholesome•15mo 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 Köse•15mo 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 Köse•15mo ago

Did you get it to work?

Monsieur Wholesome•15mo ago

Yes, I did Nah, keep it as is

Monsieur Wholesome•15mo ago

Ertan Köse•15mo ago

Monsieur Wholesome•15mo ago

$newproject

MODiX•15mo ago

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

Monsieur Wholesome•15mo ago

Ertan Köse•15mo ago

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

Monsieur Wholesome•15mo ago
