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

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