New topic in General: Opening very large 250mb+ txt files and reading line by line
XpatTech - Mon Mar 31, 2008 6:16 am <http://forums.realsoftware.com/viewtopic.php?t=21547> Pretty new to RB so this may not be possible. What I need to do is scan through some very large text files (250mb-2gb) and check for certain strings. I can load and make an exact copy using the following code. Code:dim f as FolderItem dim t as TextInputStream dim o as TextOutputStream dim s as string f= GetFolderItem("input.txt") t= f.OpenAsTextFile s= t.ReadAll f= GetFolderItem("output.txt") o= f.CreateTextFile o.write(s) What I need to now is how to scan through line by line ? Is it best done from HD or memory (Dont forget how big they may be) ? -- Over 900 classes with 18000 functions in one REALbasic plug-in.
