使用CFileDialog打开多个文件并获取文件名（转）

 // Create dialog to open multiple files.
    CFileDialog dlg(true, _T("txt"), _T("*.txt")), OFN_ALLOWMULTISELECT);

    // Create buffer for file names.
    const DWORD numberOfFileNames = 1;
    const DWORD fileNameMaxLength = MAX_PATH + 1;
    const DWORD bufferSize = (numberOfFileNames * fileNameMaxLength) + 1;
    TCHAR* filenamesBuffer = new TCHAR[bufferSize];

    // Initialize beginning and end of buffer.
    filenamesBuffer[0] = NULL;//必须的
    filenamesBuffer[bufferSize-1] = NULL;

    // Attach buffer to OPENFILENAME member.
    dlg.m_ofn.lpstrFile = filenamesBuffer;
    dlg.m_ofn.nMaxFile = bufferSize;

    // Create array for file names.
    CString fileNameArray[numberOfFileNames];
    if(dlg.DoModal() == IDOK)
    {
        // Retrieve file name(s).
        POSITION fileNamesPosition = dlg.GetStartPosition();
        int iCtr = 0;
        while(fileNamesPosition != NULL)
        {
              fileNameArray[iCtr] = dlg.GetNextPathName(fileNamesPosition);
              iCtr++;
        } 
    }
    //Release file names buffer.
    delete[] filenamesBuffer;
