MFC应用

一些简单获取路径、子路径、文件目录和判断路径有效的方法

// GetSubPath 从路径名中得到子路径LPCTSTR CDirTreeCtrl::GetSubPath(LPCTSTR strPath){static CString strTemp;int iPos;strTemp = strPath;if ( strTemp.Right(1) == ’\\’ )strTemp.SetAt( strTemp.GetLength() - 1, ’\0’ );iPos = strTemp.ReverseFind( ’\\’ );if ( iPos != -1 )strTemp = strTemp.Mid( iPos + 1);return (LPCTSTR)strTemp;}// FindSubDir 找到子目录BOOL CDirTreeCtrl::FindSubDir( LPCTSTR strPath){CFileFind find;CString strTemp = strPath;BOOL bFind;if ( strTemp[strTemp.GetLength()-1] == ’\\’ )strTemp += "*.*";elsestrTemp += "\\*.*";bFind = find.FindFile( strTemp );while ( bFind ){bFind = find.FindNextFile();if ( find.IsDirectory() && !find.IsDots() ){return TRUE;}if(!find.IsDirectory()&&m_bFiles && !find.IsHidden() )return TRUE;}return FALSE;}///获取全路径CString CDirTreeCtrl::GetFullPath(HTREEITEM hItem){CString strReturn;CString strTemp;HTREEITEM hParent = hItem;strReturn = "";while ( hParent ){strTemp = GetItemText( hParent );strTemp += "\\";strReturn = strTemp + strReturn;hParent = GetParentItem( hParent );}strReturn.TrimRight( ’\\’ );return strReturn;}// IsValidPath 判断路径是否有效BOOL CDirTreeCtrl::IsValidPath(LPCTSTR strPath){HTREEITEM hChild;CString strItem;CString strTempPath = strPath;BOOL bFound = FALSE;CFileFind find;hChild = GetChildItem( TVI_ROOT );strTempPath.MakeUpper();strTempPath.TrimRight(’\\’);while ( hChild ){strItem = GetItemText( hChild );strItem.MakeUpper();if ( strItem == strTempPath.Mid( 0, strItem.GetLength() ) ){bFound = TRUE;break;}hChild = GetNextItem( hChild, TVGN_NEXT );}if ( !bFound )return FALSE;strTempPath += "\\nul";if ( find.FindFile( strTempPath ) )return TRUE;return FALSE;}
