DirectShowのBaseClassesの一部を再現しようと思って以上のようなコードを書いたんですが

 Marshal.StructureToPtr(pbmi.bmiHeader, p, false);
 byte* PBYTE = (byte*)(void*)p;
 PBYTE += pbmi.bmiHeader.biSize;
 Win32Api.printf("data = %d, 16進数 = %x, アドレス = %p \n", *PBYTE, *PBYTE, PBYTE);

の部分で値を見ると118になるんですが、BaseClassesのほうでは204になっています。

どのようにしたら、204となるんでしょうか。すいませんが、どなたかご教示ください。

BITMAPINFOHEADER の先頭から、SizeOf(BITMAPINFOHEADER) 進めた場所…つまり、BITMAPINFOHEADER の終端の外側＝コピーされたメモリ領域の後ろにあるゴミを表示されているのですよね？

> 値を見ると118になるんですが、BaseClassesのほうでは204になっています。

「BaseClasses のほう」がどこにもないのでわかりませんが、Microsoft C++ ではデバッグビルド時には確保されたメモリ領域の後ろ側に、メモリ領域の破壊を検出するために 0xCC を数バイト埋め込むようになっています。0xCC = 204 なので、デバッグビルドされた C ランタイムが正常にガード用の 0xCC を返していて、.NET 側では p が SizeOf(BITMAPINFOHEADER) より大きく確保されているので、本当にメモリ確保した時の未初期化のゴミを表示しているだけではないでしょうか？

少なくともprintf()に正しく値が渡せていないようです。

Win32Api.printf("data = %d, 16進数 = %x, アドレス = %p \n", *PBYTE, *PBYTE, PBYTE);
Console.WriteLine("data = {0}, 16進数 = {0:X}, アドレス = {1:X8}", *PBYTE, (IntPtr)PBYTE);

でアドレスが異なります。
# 可変引数になると単純にCDECLじゃすまないですよね…。

で、このコードで何がしたいのかはいまいちわかっていません orz

正直なところ、長いコードがその中身を説明されることなく貼り続けられているので、読むのが大変です。（というか、スルー気味です）
一度、何をやりたいのか（目的・理想）、どういうコードを書いているのか（現状）、そして何を期待して（期待値）と現実はどうなっているか（実際の値）をきちんと説明してください。

そうすることで、佐祐理さんが指摘していた以下のことに対する回答になるかもしれませんね。

C++版もC#版も、このコードの目的はなんでしょう？

ヘッダー領域だけ値を初期化して、各ピクセルについては未初期化のままです。何か画像をロードしたわけでもなく、その未初期化の値をコンソール出力してるように読み取れます。何をしたいのかわかりません。

以上のように値が変わってしまいます。どなたかご教示ください。

C++版もC#版も、このコードの目的はなんでしょう？

ヘッダー領域だけ値を初期化して、各ピクセルについては未初期化のままです。何か画像をロードしたわけでもなく、その未初期化の値をコンソール出力してるように読み取れます。何をしたいのかわかりません。

  }
}

以上のようにした結果

true

Value:100 @ Address:19029604

Value:40 @ Address:1225e64

Value:0 @ Address:1225e8c

となっていて

Microsoft DirectX 9.0 SDKのサンプルのSampGrabCBのコードの一部をへんこうして

値とアドレスを表示させた結果

Grabbing samples from ruby.avi.

Value:40 @ Addres:001791C0

Value:5 @ Addres:001791E8

となってます。

C#側で、どのように変更したらよいのでしょうか。

なんども質問してすいません。

日本語に不自由していて返信が読めないのでしょうか？それとも質問することで自己満足し、それで完結しているのでしょうか？

正直なところ、長いコードがその中身を説明されることなく貼り続けられているので、読むのが大変です。（というか、スルー気味です）
一度、何をやりたいのか（目的・理想）、どういうコードを書いているのか（現状）、そして何を期待して（期待値）と現実はどうなっているか（実際の値）をきちんと説明してください。

そうすることで、佐祐理さんが指摘していた以下のことに対する回答になるかもしれませんね。

こんにちは、馬鹿１号さん。

MSDN フォーラムのご利用ありがとうございます。オペレーターの山本です。

他の方からもアドバイスいただいているように、必要以上にサンプルコード等が長くなることで、問題が分かりにくくなり、期待したような返答が付きにくくなることがあるかと思います。
もし、まだ問題を解決されていないのであれば、皆さんからのアドバイスを参考に、質問内容を整理して、必要最小限のコードを説明文とともに新規スレッドの投稿をお願いいたしますね。
その際には、必要に応じてこちらのスレッドのリンクを付けるなどしてください。

誠に恐れ入りますが、こちらのスレッドは終了させていただきますね。

今後とも、MSDN フォーラムをよろしくお願いいたします。

BaseClassesの一部をC#でテストしてもうまくいきません。どなたか教えてください。
