怎样用VC实现录音机的录音和存储功能 (用对话框做的简单录音机)

[xtao123456789]

我现在在做一个录音机 用vc6.0 运行MFC AppWizard[exe]下的对话框模式
我做了3个控件 一个录音一个保存录音一个播放 但是我不知道怎么才能实现录音和保存功能 请各位大虾指教 最好说详细点 谢了

Recording with a Waveform-Audio Device
The following example opens a waveform-audio device with a new file, records for the specified time, plays the recording, and prompts the user to save the recording if desired.

// Uses the MCI_OPEN, MCI_RECORD, and MCI_SAVE commands to record and
// save a waveform-audio file. Returns 0L if successful; otherwise,
// it returns an MCI error code.
DWORD recordWAVEFile(DWORD dwMilliSeconds)
{
UINT wDeviceID;
DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;
MCI_RECORD_PARMS mciRecordParms;
MCI_SAVE_PARMS mciSaveParms;
MCI_PLAY_PARMS mciPlayParms;

// Open a waveform-audio device with a new file for recording.
mciOpenParms.lpstrDeviceType = "waveaudio";
mciOpenParms.lpstrElementName = "";
if (dwReturn = mciSendCommand(0, MCI_OPEN,
MCI_OPEN_ELEMENT | MCI_OPEN_TYPE,
(DWORD)(LPVOID) &mciOpenParms))
{
// Failed to open device; don't close it, just return error.
return (dwReturn);
}

// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;

// Begin recording and record for the specified number of
// milliseconds. Wait for recording to complete before continuing.
// Assume the default time format for the waveform-audio device
// (milliseconds).
mciRecordParms.dwTo = dwMilliSeconds;
if (dwReturn = mciSendCommand(wDeviceID, MCI_RECORD,
MCI_TO | MCI_WAIT, (DWORD)(LPVOID) &mciRecordParms))
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}

// Play the recording and query user to save the file.
mciPlayParms.dwFrom = 0L;
if (dwReturn = mciSendCommand(wDeviceID, MCI_PLAY,
MCI_FROM | MCI_WAIT, (DWORD)(LPVOID) &mciPlayParms))
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}
if (MessageBox(hMainWnd, "Do you want to save this recording?",
"", MB_YESNO) == IDNO)
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (0L);
}

// Save the recording to a file named TEMPFILE.WAV. Wait for
// the operation to complete before continuing.
mciSaveParms.lpfilename = "tempfile.wav";
if (dwReturn = mciSendCommand(wDeviceID, MCI_SAVE,
MCI_SAVE_FILE | MCI_WAIT, (DWORD)(LPVOID) &mciSaveParms))
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}

return (0L);
}

上面的程序段实现了用mciSendCommand进行录音的功能，注意MCI_RECORD里面的MCI_WAIT标志，如果在主线程调用里出现该标志，它将租塞主线程。如果使用了MCI_WAIT标志，再开一个工作现程是一个不错的方法，以免主界面出现长时间的停顿。另外，请注意MCI_SAVE里的保存文件名和MCI_OPEN了的打开文件名，并不要求一致。

必须使用MCI_SAVE才能将指定设备录制的内容保存起来，上面的程序段分别实现了MCI_OPEN、MCI_RECORD、MCI_PLAY、MCI_SAVE，你可以根据你的实际情况将各个实现对应不同的响应。
