Newbie question about string replace
Hello world,

I wanted to replace the back slashes with forward slashes of this string:

H:\dir1\dir2\dir3\myProgram\index.html

So that the output should look like this:

H:/dir1/dir2/dir3/myProgram/index.html

How do I do this? Can somebody share their experties in this? I would appreciate some example code.

Here is the code I have as a follow up of the previous post.

Hi

Here is an example script using the StrFunc header (included as part of an NSIS install):


Name                "Replace String Test"

ShowInstDetails     Show

OutFile             'ReplaceTest.exe'

!include            "StrFunc.nsh"

; 'Declare' functions used in StrFunc.nsh
${StrRep}

Section "-Main"

    StrCpy $R0 "C:\TEMP\FOLDER"
    ${StrRep} $R1 $R0 "\" "/"
    DetailPrint "$R0 -> $R1"

SectionEnd

That was so helpful Duncan

Thanks a lot for your kindness to help.

I have tried the code, and it is so helpful and I just discover the benifit of using HM NIS Edit.

This evening I will explore and study about NSIS with it.
This two tools are entirely useful with my Java Projects.

Once again thank you very much.

Bob
