Newbie question about string replace

[oliverbob]

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):

code:


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.
