DirectXSoundでの音楽再生失敗...

Question

現在、DirectSoundにて音楽を流すところまで来ました。
しかしコードを実行しても一瞬ウィンドウが表示されるだけで、
他は何も起きません。
コードとしては、

#include<windows.h>
#include<d3d9.h>
#include<d3dx9.h>
#include<dsound.h>
#include <mmsystem.h>

DIrect3Dにて画像を描画して、音楽を再生するソースコードです。
実行に成功しているのでエラーはなく、
画像を表示するコードも入っていますが、一瞬でウィンドウが閉じてしまいます。

Answer 1

WinMain関数前に、

// Waveファイルオープン関数
// Waveファイルオープン関数
bool openWave(TCHAR* filepath, WAVEFORMATEX& waveFormatEx, char** ppData, DWORD& dataSize) {
	if (filepath == 0)
		return false;

	HMMIO hMmio = NULL;
	MMIOINFO mmioInfo;

	// Waveファイルオープン
	memset(&mmioInfo, 0, sizeof(MMIOINFO));
	hMmio = mmioOpen(filepath, &mmioInfo, MMIO_READ);
	if (!hMmio)
		return false; // ファイルオープン失敗

// RIFFチャンク検索
	MMRESULT mmRes;
	MMCKINFO riffChunk;
	riffChunk.fccType = mmioFOURCC('W', 'A', 'V', 'E');
	mmRes = mmioDescend(hMmio, &riffChunk, NULL, MMIO_FINDRIFF);
	if (mmRes != MMSYSERR_NOERROR) {
		mmioClose(hMmio, 0);
		return false;
	}

	// フォーマットチャンク検索
	MMCKINFO formatChunk;
	formatChunk.ckid = mmioFOURCC('f', 'm', 't', ' ');
	mmRes = mmioDescend(hMmio, &formatChunk, &riffChunk, MMIO_FINDCHUNK);
	if (mmRes != MMSYSERR_NOERROR) {
		mmioClose(hMmio, 0);
		return false;
	}
	DWORD fmsize = formatChunk.cksize;
	DWORD size = mmioRead(hMmio, (HPSTR)&waveFormatEx, fmsize);
	if (size != fmsize) {
		mmioClose(hMmio, 0);
		return false;
	}

	mmioAscend(hMmio, &formatChunk, 0);

	// データチャンク検索
	MMCKINFO dataChunk;
	dataChunk.ckid = mmioFOURCC('d', 'a', 't', 'a');
	mmRes = mmioDescend(hMmio, &dataChunk, &riffChunk, MMIO_FINDCHUNK);
	if (mmRes != MMSYSERR_NOERROR) {
		mmioClose(hMmio, 0);
		return false;
	}
	*ppData = new char[dataChunk.cksize];
	size = mmioRead(hMmio, (HPSTR)*ppData, dataChunk.cksize);
	if (size != dataChunk.cksize) {
		delete[] * ppData;
		return false;
	}
	dataSize = size;

	// ハンドルクローズ
	mmioClose(hMmio, 0);

	return true;
}

を入れることで解決しました
