选择一个文件

//CFileDialog dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,_T("AVI文件(*.avi)|*.AVI|mp4文件(*.mp4)|*.MP4|jpg文件(*.jpg)|*.jpg||"));CFileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, _T("媒体文件(*.avi;*.mp4)|*.AVI;*.MP4||"));if (IDOK == dlg.DoModal()){    CString aviName = dlg.GetPathName();    CString extname = dlg.GetFileExt(); //返回选定文件的扩展文件名    extname.MakeLower();}

选择多个文件

CString fileNameArray[numberOfFileNames];// Create array for file names.void CCombinDlg::OnBnClickedBtnAdd(){    // Create dialog to open multiple files.    CFileDialog Filedlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT | OFN_ALLOWMULTISELECT | OFN_EXPLORER, _T("AVI文件(*.avi)|*.AVI||"));    // Create buffer for file names.    const DWORD numberOfFileNames = 32;//最多允许32个文件    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.    Filedlg.m_ofn.lpstrFile = filenamesBuffer;    Filedlg.m_ofn.nMaxFile = bufferSize;    int iCtr = 0;    if (IDOK == Filedlg.DoModal())    {        CString aviName;        POSITION pos = Filedlg.GetStartPosition();        while (pos != NULL)        {            aviName = Filedlg.GetNextPathName(pos);//返回选定文件文件名// Retrieve file name(s).            fileNameArray[iCtr] = aviName;            iCtr++;        }    }    delete[] filenamesBuffer;//Release file names buffer.}
