replace a substring

Hello,

i want to search a substring in a File and replace it by another. in the following example, i want to replace a username by another.

ClearErrors

  FileOpen $fp '$INSTDIR\bla.cfg' r

  IfErrors notopen 0

  pop $R0

  FileRead $fp $R0

  



  FileClose $fp_zedas.cfg

  CopyFiles /FILESONLY '$INSTDIR\temp' '$INSTDIR\etc'



  notopen:

in the bla.cfg stands for example:

[Point]
username = test
password = testuser

[Point2]
loglevel = 0
Logfile= ../log/logging.log


Ok, with fileread i get the file line by line and i musst loop, thats clear. but to find the unsername i can only search by username, because the line can also be "username = dog" etc. ... and not by the complete line.

if i have the line, i musst raplace the complete line by my new entry "username = $username".

Can anybody help my?

Will this help you?

yes thanks,

but the first problem is to find the line to replace.

Use documentation before asking.

ok again:

i dont know the linenumber, so i must search .. FileRead

in every line i get, i must search a string, ... ( here im searching for a function)

edit: if my substring in the line,
than i replace the string , here i can use your first tip


you second tip finds only specified lines and the use for any string functions is also clear, but i can not use strcmp, because i dont know what string i get. and i can not use strfilter, because this function dont search for substrings

What is wrong with using WriteINIStr!?

pospec i dont want any answer from you, thanks.

Your CFG file has section headers such as [Point] which is the same as INI files. In that topic he doesn't have any which is why he has to use ConfigWrite.
