CWaveFile error in Directsound

I got this error while using CWaveFile class :


SoundTest.obj : error LNK2001: unresolved external symbol "public: __thiscall CWaveFile::CWaveFile(void)" (??0CWaveFile@@$$FQAE@XZ)
SoundTest.obj : error LNK2001: unresolved external symbol "public: __thiscall CWaveFile::~CWaveFile(void)" (??1CWaveFile@@$$FQAE@XZ)


Solution :
I added the dsutil.h and dsutil.cpp in my application.
I included the library files dxerr9.lib and winmm.lib



Next I got an error like this :

dsutil.obj : error LNK2001: unresolved external symbol _IID_IDirectSound3DListener

Solution :
