Windows XP Reg Add function .

Okay , here's my problem.

I run this command on a web page on windows NT machines and it works fine ... it doesnt work when you run it on XP machines tho :/

var cmdln = 'cmd /k reg update "HKEY_LOCAL_MACHINE\\'+
'SYSTEM\\CurrentControlSet\\Control\\'+
'Session Manager\\Memory Management\\'+
'pagingfiles"="C:\\pagefile.sys 256 256" '+''+assetnumber+'';

var shell=new ActiveXObject("WScript.shell");
shell.run(cmdln);

.. managed to figure out that there was no reg update function in XP ( wooh go me :/ ) , so changed the script slightly... to this :

var cmdln = 'cmd /k reg add "\\\\'+assetnumber'+\\HKLM\\SYSTEM\\'+
'CurrentControlSet\\Control\\'+
'Session Manager\\Memory Management\\'+
'/v PagingFiles /t REG_MULTI_SZ /d C:\pagefile.sys\0256\0256 /f"';

var shell=new ActiveXObject("WScript.shell");
shell.run(cmdln);

but recieve the error : invalid Key name

ignore the '+assetnumber+' please as this is part of another script in the page ... I have however removed it from the page to try the command and still recieve the error ..

this command works in a command prompt window : reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v PagingFiles /t REG_MULTI_SZ /d C:\pagefile.sys\0256\0256 /f

anyone any idea's as to how i'm entering the incorrect syntax for this. ?? thanks in advance much appreciated.

That's what I thought too , as when i entered it in the command prompt window , I had to enclose the key in "" to get it to work ... not sure on how i can resolve it though ... have tried enclosing the lot in "" or even ' ' , same error each time :/

cheers anyway :x

yeah , that would cause a problem with adding the asset number .. if managed to get it to work without the assetnumber part ...

this is what i used

car cmdln = 'cmd /k reg add "HKLM\\SYSTEM\CurrentControlSet\\Control\Session Manager\\Memory Management" /v PagingFiles /t REG_MULTI_SZ /d "C:\pagefile.sys 1024 1024" /f';

that changes the Virtual Memory on any XP machine that runs the web page...

just got to add the assetnumber part now :o

thanks for your help ... :)

done it . pretty simple really :/

var cmdln = 'cmd /k reg add "\\\\'+assetnumber+'\\HKLM\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management" /v PagingFiles /t REG_MULTI_SZ /d "C:\\pagefile.sys 1024 1024" /f';

(all one line )

when the prompt appears as the page loads ... just enter the netbios/ip address of the remote machine and click ok ... comman completed succesfully appears . checked the remote machine and it works.

for anyone who's interested .. the local machine needs to have ActiveX enabled ( all settings )

and this needs to be in the page header

<html>
<head>

var assetnumber= prompt('please enter asset number',' ');

if ( (assetnumber==' ') || (assetnumber==null) )
{
assetnumber="ERROR";
}

</head>
