How to write something into an opened file

[jackrabbit]

Dear all,

I am trying to write something into an opened file.

I found following functions:

FileWriteLine

FileWrite

But these two functions only append text to the end of the opened file.

Function _FileWriteToLine can write to a specific line. But this is not what I want.

I want to read a file, if I found some specific string, I will insert some string to that location. Just like the function C language provided. Is there any functions in AutoIt that can do it?

Thanks.

$File = @DesktopDir & "\Something.txt"

$sStr = FileRead($File)

<do whatever you have to do to $sStr in here>

$oFile = FileOpen($File, 2)

FileWrite($oFile, $sStr)

FileClose($oFile)

$oFile = FileOpen($File, 2)

FileWrite($oFile, $sStr)

FileClose($oFile)

That's not what the OP is asking

I saw a post in the Example forum that would do this nicely the other day: http://www.autoitscript.com/forum/index.ph...4615&hl=hex

One of use has misunderstood the question. Now it remains to be seen which one.

Thank you guys.

The FileWrite or FileWriteline is not what I need. Because it inserts the string to the end of the file. What I want is to insert the sting INSIDE a file, basically insert the string where I read some special characters in the file.

I will read SmOke_N's suggestion and see if it helps.

Thanks again.

Did you really look at that code. The part where it says to read the file to a variable first. Then do any StringReplace, StringRegExpReplace, or other string manipulation. Then you have fileopen withe the mode set to 2 which will empty the files old contents. then write the corrected contents back in and close it

Sorry, you are right. I did not read your code correctly. Your method should work. However, read everything into a single parameter and then find something will be a little bit difficult. I like to use FileReadLine to process each line. You know in C you can read the file and mark your current location.

I was wondering how come AutoIt does not have this feature.

In that case look in the help file UDFs section for _FileReadToArray. Then just loop through the array and use the same method as I gave you.

BTW: AutoIt does have FileReadLine() but that (in any language) is the slowest possible method to process a file sinply because of the way it works. It's not bad on a short file but if it is a long file then reading it to an array is the best way to go.

Thanks. I think this is a good method. I have used a different method. I read each line from the file and then write it to another file. Therefore, I can insert any string I need during this reading/writing process. I will give your method a try when I get a chance.

Thanks again for your help.
