关于一个调用PalySound方法播放声音的错误

 最近在抽空学习windows编程，跑下面代码的时候遇到了一个错误。

代码如下：

#include <windows.h>

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR szCmdLine,int iCmdShow)
{
	static TCHAR szAppName[]=TEXT("HelloWin");
	HWND hwnd;
	MSG msg;
	WNDCLASS wndclass;
	wndclass.style=CS_HREDRAW|CS_VREDRAW;
	wndclass.lpfnWndProc=WndProc;
	wndclass.cbClsExtra=0;
	wndclass.cbWndExtra=0;
	wndclass.hInstance=hInstance;
	wndclass.hIcon=LoadIcon(NULL,IDI_APPLICATION);
	wndclass.hCursor=LoadCursor(NULL,IDC_ARROW);
	wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
	wndclass.lpszMenuName=NULL;
	wndclass.lpszClassName=szAppName;

	if(!RegisterClass(&wndclass))
	{
		MessageBox(NULL,TEXT("蛋疼啊！"),szAppName,MB_ICONERROR);
		return 0;
	}
	hwnd=CreateWindow(szAppName,TEXT("还是蛋疼啊!"),
		WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT,
		CW_USEDEFAULT,
		CW_USEDEFAULT,
		CW_USEDEFAULT,
		NULL,
		NULL,
		hInstance,
		NULL,);
	ShowWindow(hwnd,iCmdShow);
	UpdateWindow(hwnd);
	while(GetMessage(&msg,NULL,0,0))
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg);
	}
	return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
	HDC hdc;
	PAINTSTRUCT ps;
	RECT rect;
	switch(message)
	{
	case WM_CREATE:
		PlaySound(TEXT("hellowind.wav"),NULL,SND_FILENAME|SND_ASYNC);
		return 0;
	case WM_PAINT:
		hdc=BeginPaint(hwnd,&ps);
		GetClientRect(hwnd,&rect);
		DrawText(hdc,TEXT("继续蛋疼!"),-1,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);
		EndPaint(hwnd,&ps);
		return 0;
	case WM_DESTROY:
		PostQuitMessage(0);
		return 0;
	}
	return DefWindowProc(hwnd,message,wParam,lParam);
}

 编译时没有报错，但是运行的时候会报如下错误：

--------------------Configuration: HelloWin - Win32 Debug--------------------
Linking...
HelloWin.obj : error LNK2001: unresolved external symbol __imp__PlaySoundA@12
Debug/HelloWin.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

HelloWin.exe - 2 error(s), 0 warning(s)

经过仔细研究之后，发现是运行的时候少了一个lib文件，故解决方案如下：

Project   Settings-> Object/library   modules   输入   Winmm.lib

再次运行OK
