== Requires ==
[[User:Sunjammer|Sunjammer]]'s [[Get_parent_directory|GetParent]] function.

== Description ==
I wrote this because I needed a way of incorporating a list of the users of a machine into an installer; there was an option to add them to a certain group and make them able to logon as a service within the installer. I listed them by simply listing the contents of the "Documents and Settings" folder, minus the obvious folders which weren't necessary.

== Usage ==
Could be cleaned up, etc. Used like this:

<highlight-nsis>
  Push $R0
  Push $R1
  Push $R2
  Push $R3

  Call getUsers

  !insertmacro MUI_INSTALLOPTIONS_WRITE "guidialog.ini" "Field 2" "ListItems" "$R3"

  Pop $R3
  Pop $R2
  Pop $R1
  Pop $R0
</highlight-nsis>

The output is a "|" separated list of users (e.g. rgrant|jworcester|bgates|smcnealy) in $R3



'''There is a possible issue with this method. If a user account has been renamed after it has been in use for a while it will retain the same folder name under Documents and Settings. Also if used with a domain, you could get different anomalies. This probably is not the best way to go about getting user names.'''

== The Function ==
<highlight-nsis>
Function getUsers

  StrCpy $R3 ""
  Push "$PROFILE"
  Call GetParent  
  Pop $R2
  StrCpy $R2 "$R2"
  FindFirst $R0 $R1 "$R2\*"
  StrCmp $R1 "" findend 0

  findloop:
  IfFileExists "$R2\$R1\*.*" 0 notDir
  StrCmp $R1 "." notDir
  StrCmp $R1 ".." notDir
  StrCmp $R1 "All Users" notDir
  StrCmp $R1 "Default User" notDir
  StrCpy $R3 "$R3|$R1"

  notDir:
  FindNext $R0 $R1
  StrCmp $R1 "" findend 0
  Goto findloop

  findend:
  FindClose $R0
  ;MessageBox MB_OK "$R3"
  
FunctionEnd
</highlight-nsis>
