Replace a String with an other in all Files
Hi all,


I have several SQL Files and a BAT File in a directory(including subdirectories). In all these files, I need to replace "C:\THIS" with "E:\THAT".

How can I do that? I also went through "Afrow_UK" Archive Page(http://nsis.sourceforge.net/archive/....php?userid=87).

Maybe Instructor's File-, Text-, Word-functions will help you.

Script to find all files (I don't remember what extentions have SQL files) in directory "C:\MySQL" with subdirectories and replace "C:\THIS" with "E:\THAT" (It's only for text files, if the directory contain binary file it will be corrupted, but you can specify directly what files to search)

Name 'Output'
OutFile 'Output.exe'

!include "FileFunc.nsh"
!include "TextFunc.nsh"
!include "WordFunc.nsh"

!insertmacro Locate
!insertmacro LineFind
!insertmacro WordReplace

Section
        ${Locate} "C:\MySQL" "/L=F /M=*.*" "LocateCallback"

        IfErrors 0 +2
        MessageBox MB_OK "Error"
SectionEnd

Function LocateCallback
        ${LineFind} "$R9" "$R9" "1:-1" "LineFindCallback"

        IfErrors 0 +3
        MessageBox MB_YESNO "Error. Continue?" IDYES +2
        StrCpy $0 StopLocate

        Push $0
FunctionEnd

Function LineFindCallback
        ${WordReplace} '$R9' 'C:\THIS' 'E:\THAT' '+' $R9

        Push 0
FunctionEnd
