Tons of errors in ws2def.h and Winsock2.h

[braindigitalis]

please show your source code plus full error output not a cropped screenshot.

did you build dpp from source, or use one of the pre built releases?
this is an issue with your project settings not an issue with the library or it would be happening for everyone.

is your project set as C++17 in the settings?

remember that you can't just include the dpp.h header and need to configure your project to include dpp.lib and also ensure that the opus and sodium etc headers are available. did you follow the setup steps here: https://dpp.dev/build-a-discord-bot-windows-visual-studio.html

*NOTE THAT OUR PREBUILT VERSIONS ARE FOR VS2019 NOT 2022 so this may have an effect on your attempts to build the bot if you are using prebuilt binaries.

Thank you, I'll try that

I have changed all my settings: I added the libraries and set the project to C++ 17 but I'm still getting all the errors. I also switched to VS2019. I'm using the release provided in the releases page.

Here's my source code:

#include <dpp/dpp.h>
#include <dpp/nlohmann/json.hpp>

void sendWebHookMsg(std::string msg) {
	dpp::webhook hook = dpp::webhook::webhook();
	nlohmann::json j;
	j["type"] = 1;
	j["name"] = "testhook";
	j["channel_id"] = "901956282964136016";
	j["guild_id"] = "901956232510844989";
	j["application_id"] = NULL;
	j["token"] = "token was here";
	j["content"] = msg;
	hook.fill_from_json(j);
	hook.build_json(true);
}

int main() {
        sendWebHookMsg("Hello, world!");
}

I'm still getting many errors:

....why is dpp in the msvc folder in program files of visual studio 2015?

You are using visual studio 2015 compiler in 2019 (14.29.30133). This is not supported as is it does not support C++17 features.
You havent set this as a C++17 project as its failing on trying to find std::variant which is a C++17 feature.

Also your entire program is wrong. This is not how you use the library or C++ in general. You can't instantiate a class by calling its constructor like a static and should not be trying to build JSON by hand. Populate the fields instead!

Start with the example template: https://github.com/brainboxdotcc/windows-bot-template and take dpp out of the program files folder! (why is it there? the tutorials on our site do not say to do this)
Take a look also at some of the example programs on dpp.dev to see how to use the library. If you are still stuck, please come to the support server at https://discord.gg/dpp
