在MFC中如何获取文件和文件夹的路径

来源：互联网发布：aoi检测算法编辑：程序博客网时间：2024/05/21 11:17

在VC++编程中，获取文件的路径很容易通过CFileDialog来实现，代码示例如下：

CFileDialog dlg(TRUE,"*.csv",NULL,OFN_FILEMUSTEXIST|OFN_PATHMUSTEXIST|OFN_HIDEREADONLY,"csv files(*.csv)|*.csv|All Files(*.*)|*.*||",NULL);dlg.m_ofn.lpstrTitle = "Open Arousal File";  //the title of the openfile dailogif(dlg.DoModal()!= IDOK)   //if don't get the arousal filereturn;arousalPath = dlg.GetPathName();  //get the arousal addressUpdateData(FALSE);

通过上面的代码就可以获得一个文件的绝对路径，但有时我们需要获得文件夹的路径以便后续的操作，相对来说，获取文件夹的路径要复杂一点。代码如下：

TCHAR szPath[_MAX_PATH];BROWSEINFO bi;bi.hwndOwner = GetSafeHwnd();bi.pidlRoot = NULL;bi.lpszTitle = "Please select the input path";bi.pszDisplayName = szPath;bi.ulFlags = BIF_RETURNONLYFSDIRS;bi.lpfn = NULL;bi.lParam = NULL;LPITEMIDLIST pItemIDList = SHBrowseForFolder(&bi);if(pItemIDList){if(SHGetPathFromIDList(pItemIDList,szPath)){InputPath = szPath;//videoPath = inputImgPath;}//use IMalloc interface for avoiding memory leakIMalloc* pMalloc;if( SHGetMalloc(&pMalloc) != NOERROR ){TRACE(_T("Can't get the IMalloc interface\n"));}pMalloc->Free(pItemIDList);if(pMalloc)pMalloc->Release();UpdateData(FALSE);}else InputPath = "";
