Multiple Files with ReadDirectoryChangesW

[NotBad]

Apologies for starting another thread on this function (and posting it in this thread, should've really gone in the Visual C++ thread...) but I'm having a problem picking up multiple files copied to a watched directory.

I have a watched directory which is picking up single files perfectly fine. However, when I drop 2 or more files into the directory, I am only able to pick up the 1st file.

My current code is as follows:

UINT CMyAppDlg::ReadDirChangesThread(LPVOID lpData)
{
	AFX_MANAGE_STATE(AfxGetModuleState());

	USES_CONVERSION;
	
	OutputThreadDebug("Directory Changes Thread Started...");
	CString csFilename = "";
	
	ThreadData *pData = (ThreadData*) lpData;
	
	HANDLE hDir = ::CreateFile(pData->csDirectory,	FILE_LIST_DIRECTORY,	FILE_SHARE_READ|FILE_SHARE_DELETE|FILE_SHARE_WRITE,
		NULL,
		OPEN_EXISTING,
		FILE_FLAG_BACKUP_SEMANTICS,
		NULL);
	
	ASSERT(hDir != INVALID_HANDLE_VALUE);			
	
	FILE_NOTIFY_INFORMATION Buffer[512];
	memset((void*)&Buffer,0,sizeof(Buffer));
	DWORD dwBytesReturned;
	BOOL bFound = FALSE;

	do
	{
		if (ReadDirectoryChangesW(hDir,&Buffer,
			sizeof(Buffer),
			FALSE,
			FILE_NOTIFY_CHANGE_FILE_NAME,
			&dwBytesReturned,
			NULL,
			NULL))
	                   {
			
			csFilename = (CString(Buffer[0].FileName).Left(Buffer[0].FileNameLength / 2));

// Do something with the filename
                                    }

// Post a message to the calling thread indicating that we've finished
::PostMessage(pData->ParenthWnd,UWM_THREAD_FINSHED,0,0);
::OutputDebugString("Thread finished\n");
}

I know this will only ever pick up one filename, but I was hoping there would be a nice easy way to modify this to pick up multiple filenames and add them to thread safe array maybe?

Or would it be easier to run this in asynchronous mode? Or am I doing this compeltely wrong?!
