如何使用C ++编译项目，以便在硬盘上创建项目的.dll文件，以便以后将其与其他程序一起使用？

Question

This is the main code:

// DSPlayer.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include "DSPlayer.h"
#include "resource.h"
#include "PlayerClass.h"


/********* GLOBAL VARIABLES **********/
HINSTANCE g_hInst;
HWND g_hDialogWindow;

// pointer to my PlayerClass obejct
PlayerClass *g_PlayerObject = NULL;

    MSG msg;

    HICON iconLarge = NULL;

    InitCommonControls();

    g_hInst = hInstance;

    g_hDialogWindow = CreateDialog(hInstance, MAKEINTRESOURCE(IDD_DLGDSPLAYER), NULL, (DLGPROC)DlgDSPlayerProc);

    // this will set the icon for my player
    iconLarge = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_ICONLARGE));

    if (iconLarge)
    {
        SendMessage(g_hDialogWindow, WM_SETICON, ICON_BIG, (LPARAM)iconLarge);
    }


    // Initialize the COM library
    CoInitialize(NULL);


    if (!g_hDialogWindow)

    }

    return handled;

}

It's not my project.

Now I went to the project properties and under General>Target Extension its: .dll And under General>Configuration Type> its: Dynamic Library (.dll)

But when I'm doing doing to my project Build>Build Solution I can't find any .dll files the the Debug directory.

I'm using Visual Studio C++ Express 2010.

What am I missing here?

How and where do i have to fix this warnings ? can someone upload here a screenshot to show me how and where to do it ?

在输出目录和中间目录中写入。\\ Debug，然后单击“清理并生成”，即使发生此警告，它也会生成.exe文件
