getopenfilename多选文件/文件夹问题和getsavefilename另存为路径

关于使用getopenfilename多选多个文件是可以的。

以下是多选文件的代码

 bool GetNeedOpenFilePath(vector<tstring>& vectFiles, HWND hwnd )
 {
     OPENFILENAME ofn;
     TCHAR szOpenFileNames[*MAX_PATH] = {};
     TCHAR szPath[MAX_PATH];
     TCHAR szFileName[*MAX_PATH];

     int nLen = ;
     TCHAR* p = NULL;
     ZeroMemory(&ofn, sizeof(ofn));

     ofn.lStructSize = sizeof(ofn);
     ofn.hwndOwner = hwnd;
     //ofn.hInstance = (HMODULE)GetCurrentProcess();
     ofn.lpstrFile = szOpenFileNames;
     ofn.nMaxFile = sizeof(szOpenFileNames);
     ofn.lpstrFile[] = _T('\0');
     ofn.lpstrFilter = _T("All Files(*.*)\0*.*\0\0");
     ofn.nFilterIndex = ;
     ofn.lpstrFileTitle = NULL;
     ofn.nMaxFileTitle = ;
     ofn.lpstrTitle = I18NSTR(L"#IDS_FILESYSTEM_OPEN_FILE_DIR");
     ofn.Flags = OFN_ENABLESIZING | OFN_FILEMUSTEXIST| OFN_ALLOWMULTISELECT| OFN_HIDEREADONLY /*| OFN_ENABLEHOOK *//*| OFN_ENABLEINCLUDENOTIFY*/| OFN_EXPLORER;
     //ofn.lpfnHook = OFNHookProc;
     if (!::GetOpenFileName(&ofn))  //如果打开文件失败，则不操作
     {
         return false;
     }

     //把第一个文件名前的复制到szPath,即:
     //如果只选了一个文件,就复制到最后一个'/'
     //如果选了多个文件,就复制到第一个NULL字符
     lstrcpyn(szPath,szOpenFileNames,ofn.nFileOffset);

     //当只选了一个文件时,下面这个NULL字符是必需的.
     //这里不区别对待选了一个和多个文件的情况

     szPath[ofn.nFileOffset] = '\0';
     nLen = lstrlen(szPath);
     if (szPath[nLen-] != '\\')  //如果选了多个文件,则必须加上'//'
     {
         lstrcat(szPath,_T("\\"));
     }

     p = szOpenFileNames + ofn.nFileOffset;  //把指针移到第一个文件
     ZeroMemory(szFileName, sizeof(szFileName));

     while(*p)
     {
         //lstrcat(szFileName, szPath);     //给文件名加上路径
         //lstrcat(szFileName, p);             //加上文件名
         tstring tstrFile = _UTILITY::TCHARToUnicode(p);
         tstring tstrFilePath = szPath;
         tstrFilePath += tstrFile;
         vectFiles.push_back(tstrFilePath);
         //lstrcat(szFileName, _T("\n"));   //换行
         p += lstrlen(p) + ;             //移至下一个文件
     }

     return true;
 }

但是关于使用getopenfilename()函数获取多选文件夹的路径问题，需要自定义一些模板资源。具体实现方式还需研究下。

使用getsavefilename()函数可以获取另存为路径：

 bool GetSaveAsFilePath(tstring tstrFilePath, HWND hwnd)
 {
     OPENFILENAME ofn;
     TCHAR szOpenFileNames[*MAX_PATH] = {};
     TCHAR szPath[MAX_PATH];
     TCHAR szFileName[*MAX_PATH];

     int nLen = ;
     TCHAR* p = NULL;
     ZeroMemory(&ofn, sizeof(ofn));

     ofn.lStructSize = sizeof(ofn);
     ofn.hwndOwner = NULL;
     //ofn.hInstance = (HMODULE)GetCurrentProcess();
     ofn.lpstrFile = szOpenFileNames;
     ofn.nMaxFile = sizeof(szOpenFileNames);
     ofn.lpstrFile[] = _T('\0');
     ofn.lpstrFilter = _T("All Files(*.*)\0*.*\0\0");
     ofn.nFilterIndex = ;
     ofn.lpstrFileTitle = NULL;
     ofn.nMaxFileTitle = ;
     ofn.lpstrTitle = I18NSTR(L"#IDS_FILESYSTEM_SAVE_AS");
     ofn.Flags = OFN_HIDEREADONLY | OFN_PATHMUSTEXIST | OFN_EXPLORER;
     ofn.FlagsEx = OFN_EX_NOPLACESBAR;
     //ofn.lpfnHook = OFNHookProc;
     if (!::GetSaveFileName(&ofn))  //如果打开文件失败，则不操作
     {
         return false;
     }

     tstrFilePath = ofn.lpstrFile;
     return true;
 }
