SDKでサンプルのhttpクラスをコンパイルしようとしていて、いくつかの奇妙なリンクエラーが発生しました...私は、欠けているオプションやディレクトリと何かをすると確信しています...C++ WinHttp/Windows SDKでコンパイルの問題
私はあなたが見ることができるようにC + +の専門家ではありませんが、援助を探しています。
私のサンプルクラスが含まれています。私はWindows SDKもインストールしました。自分の設定やその他の情報が必要な場合は、質問してください。誰かがWinHttp SDKサンプルプロジェクトの作業を指していることをお勧めしたいと思います。

変更プロジェクト設定をwinhttp.libたり、.cppファイルに次の行を追加してリンクする必要が
