Hidden shares on UNC paths
Hi all

Its been a while since I've been around here...I hope everyone is as helpful as ever!

I'm trying to use strCpy to copy a UNC path with a hidden share but it seems to have trouble parsing the dollar sign in the path. I've tried double dollars to escape it but that makes things worse!

This is very similar to what I've been playing with:

Section ""
  Var /GLOBAL uncpath
  StrCpy $uncpath "\\filesrv01\myfolder$\inifile.ini"
  ReadINIStr $R1 $uncpath MYSECTION myatt
  MessageBox MB_OK "Value of R1 is '$R1'"
SectionEnd

Any ideas on how to make this work successfully or do I have to avoid hidden shares?

Section ""
  Var /GLOBAL uncpath
  StrCpy $uncpath "\\filesrv01\myfolder$$\inifile.ini"
  MessageBox MB_OK "Value of $$uncpath is '$uncpath'"
SectionEnd

This is also what I tried but it fails...I dont care about the message box just the ini value but using that string in StrCpy ends up in error wiht the first char removed from the inifile.ini, looking at the output from the compile.

Any further suggestions?

Is this supposed to work?

BTW, I'm using the latest build downloaded from SF today, 2.14?

Thanks!

hmm... Your sample worked fine for me. What version of NSIS are you using? I've got 2.14.

My sample script:

name "test backslash"
outfile "Test Backslash.exe"
var mypath
Section
Sectionend

function .oninit
   Setsilent silent
   strcpy $mypath "\\filesrv01\myfolder$$\inifile.ini"
   messagebox MB_OK "$$mypath = $mypath"
FunctionEnd

Yeah that works for me too. The problem seems to be that my inifile.ini actually begins with a "t"...so much for sanitising my examples. So the path is actually:

\\filesrv01\myfolder$$\tinifile.ini

Which generates an error (ignored) during compile.

My solution was to rename the inifile but I'm curious to know how to fix this issue when the inifile does begin with "t".

Thanks!

Might be a bug. It acts like it's interpreting the "$\t" as a tab character (reference) regardless of the escaped the dollar sign.

On the other hand, it could be a design decision.

Bug? Maybe..

But, here's a workaround (or a solution, depending on how you look it!)

name "test backslash"
outfile "Test Backslash.exe"
var mypath
var dol 
Section
Sectionend

function .oninit
   Setsilent silent
   strcpy $dol "$$"
   strcpy $mypath "\\filesrv01\myfolder$dol\tnifile.ini"
   messagebox MB_OK "$$mypath = $mypath"
FunctionEnd
