私はWTLに非常に慣れていません。ここに私のメインダイアログのonCreateのコードがあります

int Cwin32_mfcDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CDialogEx::OnCreate(lpCreateStruct) == -1)
        return -1;

    // TODO:  Add your specialized creation code here
    MARGINS mar = {0};
    mar.cyBottomHeight = 100;
    DwmExtendFrameIntoClientArea(m_hWnd,&mar);
    return 0;
}

しかし、プロジェクトをコンパイルしようとすると、このエラーが発生します

error LNK2019: unresolved external symbol __imp__DwmExtendFrameIntoClientArea@8 referenced in function "public: int __thiscall Cwin32_mfcDlg::OnCreate(struct tagCREATESTRUCTA *)" (?OnCreate@Cwin32_mfcDlg@@QAEHPAUtagCREATESTRUCTA@@@Z)

そしてここに出力があります：

これは私の StdAfx.h コードです:

このプロジェクトは、MFC と Visual Studio 2010 および Windows 7 x64 にあります。

からDwmExtendFrameIntoClientArea()とリンクする必要がありますDwmapi.lib。
