Windows Users, Detect & List

Author: RobGrant (talk, contrib)

Requires

Sunjammer's 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:

  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

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

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
