CookieGetterSharp.dllを使ってニコニコ生放送の枠取りを半自動化してみた

Visual C# C Sharp

まず、halxxxxさんの、CookieGetterSharp.dll + SourceCode + SampleCodeを

http://d.hatena.ne.jp/halxxxx/20091212/1260649353

から取得します。

これを利用するにあたっては、私は、解凍したものを自プロジェクトのディレクトリ配下に置いて参照設定しました。解凍すればそのまま、

CookieGetterSharp.dll
CookieGetterSharp.xml
System.Data.SQLite.DLL

が同じディレクトリに置かれているので。。

VC#のIDEで自プロジェクトを作成後、「プロジェクト」->「参照の追加」で、CookieGetterSharp.dllへの参照を追加して利用しました。
あとSgmlReaderDll.dllという別のライブラリも利用させてもらったのですが、ググればわかると思うので、足りなそうだったら後日補足します(というか覚えてない)。。
