Registry plugin

[Instructor]

Features:

- Powerful registry search:
   -fast algorithm
   -principle of turn in stack (first in -> last out)
    i.e. search from first registry key to last
   -search for key, value and/or string in any root
   -search with name and/or type
   -search with banner support
   -search with subkeys or not
- Read value of any type
- Write value of any type
- Create key
- Delete key       (same as DeleteRegKey)
- Delete value    (same as DeleteRegValue)


Some performance info:

Search in all HKEY_LOCAL_MACHINE where 60351 keys, 84714 values, 84714 strings

Search only NOT existed value:    (/K=0 /V=1 /S=0 /N=`#Not Existed#`)
  With /B=0: 0 min 9 sec 580 ms
  With /B=1: 0 min 16 sec 300 ms
  With /B=2: 1 min 19 sec 486 ms

Search any keys, values, strings:  (/K=1 /V=1 /S=1 /N=``)
  With /B=0: 2 min 46 sec 664 ms
  With /B=1: 2 min 56 sec 974 ms
  With /B=2: 6 min 2 sec 668 ms

Hey Instructor, nice work.

I had started experimenting doing something similiar with the system plugin. But yours looks much better!

Any chance you'll be adding support to import/export REG files?

[Instructor]

Hi, Comperio.

Import/export simply doing with API RegSaveKey, RegRestoreKey and RegReplaceKey, BUT:

[MSDN]
Remarks

There are two different registry hive file formats. Registry hives created on current operating systems typically cannot be loaded by earlier ones.

RegRestoreKey

[MSDN]
Requirements
Windows NT/2000/XP: Included in Windows NT 3.1 and later.
Windows 95/98/Me: Unsupported.
Header: Declared in Winreg.h; include Windows.h.
Library: Use Advapi32.lib.
Unicode: Implemented as Unicode and ANSI versions.

So, probably there is only way to save multi-OS compatibility - write manually REG parser. I'll think that I can do.

[Comperio]

hmmm. I see your point. But, if you can do it, I think importing/exporting REG files would be a very cool feature.

And something you might consider:
Most of the time, (at least for me anyway), reg files would be used as a means to backup and restore on the same system. So I don't think it's too important that a reg file created on a 9x computer is compatible with a XP computer. (Personally, if I were going to import reg files as part of an install, then I'd probably have 2 files--one for XP and one for 2K).

But that's just me... Someone else may have a different view...

Changes:
-Merged with REGEDIT4 plugin, probably this will be more comfortable for user.
 Increase plugin size to 13Kb, but you can simply recompile it, only with functions you need (see defines at the beginning of registry.c).

-Fixed: registry:eleteKey in NT systems didn't delete subkeys

-Fixed: problem with compiling "RegistryTest.nsi" when nxs plugin isn't exist

-Now registry::RestoreKey checks if file exist


"Registry" plugin v1.1

[Instructor]

Changes:
-Fixed: Double calling GlobalFree in some case, that can cause crash
(registry::Find, registry::Close)

-Fixed: REG_RESOURCE_LIST, REG_NONE readed as string, instead of binary
(registry::Find, registry::Read)

-Added: Converts string to hex values
(registry::StrToHex)

-Added: Converts hex values to string
(registry::HexToStr)

-Full registry value types support, added:
REG_FULL_RESOURCE_DESCRIPTOR
REG_RESOURCE_REQUIREMENTS_LIST
REG_QWORD


BTW:
While testing plugin in Microsoft XP I was found errors in REGEDIT with /a switch:
-National characters incorrect exports from registry in hex format
(first hex digit: c->1 d->2 e->3 f->4)
-Special escape sequence "\n" is not replaced with "\\n"


"Registry" plugin v1.2

[Brummelchen]

Short question cause urgent

can i find all entries "defaulticon" with it ?
And can i export them ?

###
well that works, but i have empty entries

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.nsc\DefaultIcon]

@=''

it has to be

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.nsc\DefaultIcon]

@="dxmasf.dll,-502"

not all are empty

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Scripting Host\Script Extensions\.JS\DefaultIcon]

@='%SystemRoot%\System32\wscript.exe,3'

Name "DefaultIcon"
OutFile "DefaultIcon.exe"

Section 
SectionEnd

Function .onInit
  IfFileExists "DefaultIcon.reg" 0 noreg
    Delete DefaultIcon.reg
  noreg:

  FileOpen $R1 "DefaultIcon.reg" w
  FileWrite $R1 "REGEDIT4"
  FileWriteByte $R1 "13"
  FileWriteByte $R1 "10"
  FileWriteByte $R1 "13"
  FileWriteByte $R1 "10"

  registry::Open /NOUNLOAD "HKEY_LOCAL_MACHINE" "/K=1 /V=1 /S=1 /B=1 /N='DefaultIcon'" .r0
  StrCmp $0 -1 end

  loop:
    registry::Find /NOUNLOAD .r1 .r2 .r3 .r4
    IfErrors end
    StrCmp $1 "" end
    StrCmp $2 "" end
    ;StrCmp $3 "" loop
    ;StrCmp $4 "" loop

    FileWrite $R1 "[HKEY_LOCAL_MACHINE\$1\$2]"
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"
    FileWrite $R1 "@='$3'"
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"

  Goto loop

  end:
  registry::Close

FileClose $R1
FunctionEnd 

[Brummelchen]

Ok, i did it this way..

Name "DefaultIcon"
OutFile "DefaultIcon.exe"
AutoCloseWindow true

Section 
SectionEnd

Function .onInit
  IfFileExists "DefaultIcon.reg" 0 noreg
    Delete DefaultIcon.reg
  noreg:

  FileOpen $R1 "DefaultIcon.reg" w
  FileWrite $R1 "REGEDIT4"
  FileWriteByte $R1 "13"
  FileWriteByte $R1 "10"
  FileWriteByte $R1 "13"
  FileWriteByte $R1 "10"

  registry::Open /NOUNLOAD "HKEY_LOCAL_MACHINE" "/K=1 /V=1 /S=1 /B=1 /N='DefaultIcon'" .r0
  StrCmp $0 -1 end

  loop:
    registry::Find /NOUNLOAD .r1 .r2 .r3 .r4
    IfErrors end
    StrCmp $1 "" end
    StrCmp $2 "" end
    ;StrCmp $3 "" loop
    ;StrCmp $4 "" loop

    ReadRegStr $R2 HKLM "$1\$2" ""

    ;MessageBox MB_OKCANCEL "'$1\$2'$\n'$R2'$\n'$3''" IDCANCEL end

    FileWrite $R1 "[HKEY_LOCAL_MACHINE\$1\$2]"
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"

    StrCmp $3 "" write_reg1
      FileWrite $R1 "@='$3'"
      Goto write_reg2
    write_reg1:
      FileWrite $R1 "@='$R2'"
    write_reg2:
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"
    FileWriteByte $R1 "13"
    FileWriteByte $R1 "10"

  Goto loop

  end:
  registry::Close

FileClose $R1
FunctionEnd 

[Instructor]

well that works, but i have empty entries

This because "DefaultIcon" it is key (REG_KEY) and when key is found value and string are empty.

not all are empty

Do you use v1.2? In previos versions in NT systems strings not always updated.

[Instructor]

Changes:
-Fixed: Cross-calling functions. Now posible for example:
  registry::Open /NOUNLOAD ...
  registry::Find /NOUNLOAD ...
  registry::Read /NOUNLOAD ...
  registry::Write /NOUNLOAD ...
  registry::Close

-Fixed: registry::Read, when reading not existed value, returns "INVALID" registry type instead of "" (all output variables must be empty)

-Fixed: REG_LINK readed as string instead of binary

-Now posible to find default values (any type) or/and empty strings (REG_SZ, REG_EXPAND_SZ). Options with /N="" searches for empty names and without /N= for all names


"Registry" plugin v1.3

[Brummelchen]

well - see - "defaulticon" can be in the path
[...\DefaultIcon]
and as an entry.
"DefaultIcon"=

And the example below has it both in the path...
but only one of it is read out

yes, was 1.2 and 1.3 shows same behaviour.

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.nsc\DefaultIcon]

@=''

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Scripting Host\Script Extensions\.JS\DefaultIcon]

@='%SystemRoot%\System32\wscript.exe,3'

[Instructor]

Try "Search and write founded in text file" example in RegistryTest.nsi with your registry::Open parameters and check output file.

[edit]
I have tested it with options you wrote before ["HKEY_LOCAL_MACHINE" "/K=1 /V=1 /S=1 /B=1 /N='DefaultIcon'"] and all fine.
[/edit]

[edit2]
Tested on XP and all fine. Founded ".JS" key, "DefaultIcon" is value - check your script:

code:


REG_SZ:"SOFTWARE\Microsoft\Windows Scripting Host\Script Extensions\.JS" "DefaultIcon"="%SystemRoot%\System32\wscript.exe,3"

[/edit2]

[Brummelchen]

its not "JS"-problem, its here

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.nsc\DefaultIcon]

@=''

has to be

code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.nsc\DefaultIcon]

@="dxmasf.dll,-502"

on some reason it is empty - try the first script above and test it pls (not the second)

[Instructor]

Why you didn't test "Search and write founded in text file"? With it no problem there is something in your script. Like I said before if you find registry key then string is EMPTY, registry::Find can't find registry key and they default string at the same time. You need to read it.
Try this:

code:


Name "DefaultIcon"

OutFile "DefaultIcon.exe"

AutoCloseWindow true



!include "WordFunc.nsh"

!insertmacro WordReplace



Section

	StrCpy $R0 HKEY_LOCAL_MACHINE

	FileOpen $R1 "DefaultIcon.reg" w

	FileWrite $R1 "REGEDIT4$\r$\n$\r$\n"



	registry::Open /NOUNLOAD "$R0" "/K=1 /V=0 /S=0 /B=1 /N='DefaultIcon'" .r0

	StrCmp $0 -1 end



	loop:

	registry::Find /NOUNLOAD .r0 .r1 .r2 .r3

	StrCmp $3 "" end



	registry::Read /NOUNLOAD "$R0\$0\$1" "" .r4 .r5 .r6 .r7

	StrCmp $6 "" loop



	${WordReplace} "$6" "\" "\\" "+" $6

	${WordReplace} "$6" '"' '\"' "+" $6

	FileWrite $R1 '[$R0\$0\$1]$\r$\n'

	FileWrite $R1 '@="$6"$\r$\n$\r$\n'

	Goto loop



	end:

	registry::Close

	FileClose $R1
