MFC浏览文件夹，浏览保存文件， 获取当前路径

浏览文件夹，其实用的是Shell里的API

 void OnXXXBrowse()
 {
     CString    strFolderPath;
     BROWSEINFO broInfo = {0};
     TCHAR       szDisName[MAX_PATH] = {0};

     broInfo.hwndOwner = this->m_hWnd;
     broInfo.pidlRoot  = NULL;
     broInfo.pszDisplayName = szDisName;
     broInfo.lpszTitle = _T("选择保存路径");
     broInfo.ulFlags   = BIF_NEWDIALOGSTYLE | BIF_DONTGOBELOWDOMAIN
         | BIF_BROWSEFORCOMPUTER | BIF_RETURNONLYFSDIRS | BIF_RETURNFSANCESTORS;
     broInfo.lpfn      = NULL;
     broInfo.lParam    = NULL;
     broInfo.iImage    = IDR_MAINFRAME;

     LPITEMIDLIST pIDList = SHBrowseForFolder(&broInfo);
     if (pIDList != NULL)
     {
         memset(szDisName, 0, sizeof(szDisName));
         SHGetPathFromIDList(pIDList, szDisName);
         strFolderPath = szDisName;
     }
 }

浏览保存文件

 void BrowseSaveFile()
 {
     LPCTSTR szFilter = _T("puk files(*.puk)|*.puk||");

     // CFileDialog的第一个参数标明是浏览还是保存
     CFileDialog dlg(TRUE, NULL, NULL,  OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, szFilter);
     if (dlg.DoModal() == IDOK)
     {
         CString fileName = dlg.GetPathName();
     }
 }

获取当前路径

 void GetCurPath()
 {
     CString strCurPath; // 不包含文件名的全路径
     GetModuleFileName(NULL, strCurPath.GetBufferSetLength(MAX_PATH + 1), MAX_PATH);
     strCurPath.ReleaseBuffer();
     int nPos = strCurPath.ReverseFind('\\');
     strCurPath = strCurPath.Left(nPos + 1);
 }
