how can i remove 1 line from a text document without opening it

could you please explain what your trying to do? I'm totally lost with this question, maybe if I understood, I could help, not being rude or anything, I just want to help you, I just don't understand.

------
edit: you mean to remove a sentence in a notepad .txt file without even opening it up ?

[Kevin]

i am checking a inside a file for a text then trying 2 remove that text from the file.But the catch is the file isn't open at all

[Kevin]

i know how 2 find the specific text inside the file just not how 2 remove it

i know how 2 find the specific text inside the file just not how 2 remove it

hock: can you post your code? I may be able to make a str for the text found & delete it. just need 2 get started off with the code :lol:


---
edit: because idk how 2 get the text from a non-open file, & it would make it much easier to expierment with deleteing the found text if I knew how to get the text. :lol:
---
edit again: you don't gotta post the whole code, just show me how to get the text of a file not opened, & I can come up with something most likely to delete the specified text.

I have never tried something like this before but I would say try using something like this:

For end of macro:

,if b=s
,,a.findreplace(b)
,a.setfile("$Desktop$\test.txt" -1)


I don't know if this would work or not but it might be worth a shot.

[Kevin]

not quite. it did delete the entry after it added everything else again but the orignal line was still there

[Kevin]

ok i managed 2 delete the line but it is replace but a blank line now

[Kevin]

i got it had 2 delete the file first
ty for your help

[QM Assistant]

Anytime.

[Kevin]

ok it works but only problem is it leaves a blank line in the file

[Kevin]

this is the whole code i am using for testing

Code:

Copy      Help

str a b
b="remove this line"
a.getfile("$Desktop$\test.txt")
str s
foreach s a
,if b=s
,,a.findreplace(b)
,,del "$Desktop$\test.txt"
,,a.setfile("$Desktop$\test.txt" -1)

Code:

Copy      Help

str a
a.getfile("$Desktop$\test.txt")
;a.RemoveLineN(4);; deletes line 5 from file
a.RemoveLineN(numlines(a)-1);; deletes last line of file
a.setfile("$Desktop$\test.txt")

You must have Member function str.RemoveLineN
(To add new Member function) while QM window is active press and release (Ctrl+Alt+N) this will add a new Member function make sure you name the new Member function (str.RemoveLineN), and add the below code to it.

str.RemoveLineN

Code:

Copy      Help

function# lineindex [nlines]

;Removes specified line(s).
;Returns index of first character of lineindex-th line, or -1 if lineindex is too big.

;lineindex - zero-based line index.
;nlines - number of lines to remove. Default or 0: 1 line.

;EXAMPLE
;str s="zero[]one[]two"
;s.RemoveLineN(1)
;out s


if(nlines<1) nlines=1
int i=findl(this lineindex)
if(i>=0) this.remove(i findl(this+i nlines))
ret i

[Kevin]

ty for your rsponse i looked at that and tried it and again for some reason i have 2 dlete the file and resave it also had 2 add a code 2 count the lines but that was no biggie.if i don't delete the file it adds every other name again and doesn't delete the entry i wanted except on the when it adds all the lines in the file again 2 the file

[John]

If you use flag (-1) with setfile it will append the text to the file not replace it like you're wanting to do, don't use any flag at all. As far as the counting I dont know why you would have to do that, numlines() will do that for you.

[Kevin]

ok ty yeah once i removed the flag it works without deleting but i have 2 get the line count cause the entry could be on any line. maybe line 5 our could be line 25 u never know.so i just made it count the line so i had the line number 2 delete.Cause it won't let me use anything but a number or an integer in this line
a.RemoveLineN(x)<-----x being an integer

[John]

Sounds like you have it then ?

[Kevin]

yes i do tyvm.I didn't use the numblines line cause i wasn't sure how 2 implement it.So that's why i had 2 adapt it 2 count the lines

[John]

Glad I could help.

[Kevin]

i'm having a problem saving a file if the text begins with things like this
**==
^^
any thoughts why?

[Kevin]

what is happening is if the text of the window starts with characters like that i can't save the file name as that text of the window

Member function str.ReplaceInvalidFilenameCharacters. Create it using menu File -> New -> New Member Function.

Code:

Copy      Help

function# [$replaceto]

;Some characters cannot be used in file names. This function replaces
;these characters to valid characters or just removes them.

;EXAMPLE
;str s="file*\[9]name.txt"
;s.ReplaceInvalidFilenameCharacters("_")
;out s
;s-"$desktop$\"
;s.setfile(s)


replacerx("[\\/|<>?*:''[1]-[31]]" replaceto)
