String Replace Problem...
Hi,

In my installer, the user specify something that I Put in a variable. After that, I use a RiF Function with StrRep Function to Replace a String in a Txt file with variable created by the user input.

Exemple: User input: A2sd (i put that in $VarExemple)

In the script, I do :

!insertmacro ReplaceInFile "D:\somefile.txt" "_text" "$VarExemple"

The text file is like that :

Bla Bla Bla Bla Bla
Bla bla bla bla bla
I want to Some_textC tell you
Bla Bla Bla Bla Bla
Bla Bla Bla Bla Bla


The expected result would be :

Bla Bla Bla Bla Bla
Bla bla bla bla bla
I want to SomeA2sdC tell you
Bla Bla Bla Bla Bla
Bla Bla Bla Bla Bla

But here is what it does :

Bla Bla Bla Bla Bla
Bla bla bla bla bla
I want to SomeA2sd
C tell you
Bla Bla Bla Bla Bla
Bla Bla Bla Bla Bla

I've not tested it, but you could try this function:

Otherwise, you might want to post your current ReplaceInFile macro here and see if someone can help spot the problem.
