erasing lines from end of file

[erezlevi]

hi, all.

how can I erase lines from the end of file after opening it for edit:

$file=FileOpen  ("c:\0522554720.htm",1)

I want to erase lines from the end of the file.

_FileReadtoArray

The for loop, and filewriteline.

But how do you not write the last lines? The secret is in the to of the for loop. see if you can work it out. Hint, expressions can be used...

You could use _FileCountLines to get the number of the last line in the file and then use _FileWriteToLine without any text to delete the line without having to open the file.

Thanks for your responses,

I'v choose the :

$filechange=_FileWriteToLine("c:\0522554720.htm",85, "my replacement for line 85", 1)

it erases the part i don't need from previus action and replaces it with new data continuasly. instead of using "my r...." i will use an $i string that allways changes.

Hi,

Don't forget the link in my sig for superfast read/ write / delete at end of file, as you don't even need to read the file! (APITailRW.zip)
