How to insert the words "I am Trung Nguyen on the 2nd line

scila1996,

You want to write a specific line to a file - I wonder if there is a function in the Help file that looks as if it might help you?

Aha, there is "_FileWriteToLine", which strangely enough does exactly what you require.

What have you tried so far? If this were my project, I'd consider using:

• FileOpen: to open the file to read and the file to write to
• FileReadLine: to read each line of the file of the input file
• FileWriteLine: to write each line from the input file to the output file
• I'd also use FileWriteLine to write the additional line of interest
• FileFlush: This may be needed to flush the buffers and write all to the output file
• FileClose: to close both input and output files.
• Then you will probably want to delete the input file and rename the output file to match the original file.

 

Oops, I missed _FileWriteToLine as noted by Melba, a function that would simplify all of this... D'oh!

Oh No 

I know this syntax. But I mean 

 

- I have 3 lines of text including 

Line 1: Hello 

Line 2: I Am Trung Nguyen

Line 3: Polytechnic University 

 

 

 

 

I want to put this text into 

 

"Information Technology Department" ---> insert into 2 lines like this. 

Line 1: Hello 

Line 2: Faculty of Information Technology 

Line 3: I Am Trung Nguyen

Line 4: Polytechnic University

_FileWriteToLine("Ur file path", number of line i want to insert it, "What i want to insert", 0)

 
;Pratic Example
 
_FileWriteToLine("c:\test.txt", 3, "blablabla", 0)

scila1996,

 

Oh No

Oh Yes!

The _FileWriteToLine function I recommended is exactly what you want - have you tried it? Post the code you used if it did not work.

scila1996,

 

I tried

But obviously not very hard!

#include <File.au3>

$sFile = "Test.txt"

FileWrite($sFile, "Hello" & @CRLF & "I Am Trung Nguyen" & @CRLF & "Polytechnic University")

MsgBox(0, "Original", FileRead($sFile))

_FileWriteToLine($sFile, 2, "Faculty of Information Technology")

MsgBox(0, "Amended", FileRead($sFile))

FileDelete($sFile)

Does that work for you?

You can try to think at least a bit. What you want is to insert text at a specific line correct?
So why do you think that the suggested function is not the correct one? Doesn't seem like you have tried at all.

#include <File.au3>

$sFile = @AppDataDir & "\test12345.txt"
$hFile = FileOpen($sFile, 10)
FileWrite($hFile, "line 1" & @CRLF & "line 2" & @CRLF & "line 3" & @CRLF & "line 4" & @CRLF & "line 5")
FileClose($hFile)

$iTargetLine = 4
$sTargetString = "This gets inserted"
_FileWriteToLine($sFile, $iTargetLine, $sTargetString)

ShellExecute($sFile)
MsgBox(0, "", "Result", 5)
FileDelete($sFile)

Seems like Melba beat me.
