Detect path to WINDOWS directory ?

There is a component available from, amongst others, this site:

http://www.worldnet.net/~cycocrew/delphi/components.html

called TFileFind, which should provide the help you need. Either use the component wholesale, or examine the source code to write your own.

Use the variable WINDIR in your program.  It contains the path to windows.

I can't get it to work. It's a Pchar type of variable, isn't it ?
I'm using this code to detect if there is a file in WINDOWS\SYSTEM directory:

if FileExists(WINDIR + '\System\' + 'nviewlib.dll')=false then...

I declared the WINDIR variable as PChar.
The program reports no errors but can not find the file that is there.
Is there something I have to add to USES clause ?
How can I get it to work ?

I can't get ozzy's answer to work either.  However, this simple function will DEFINITELY work.  If you like it, reject ozzy's answer, and i'll repost it as an answer.

function WinDir:  string;
var
buff:  array[0..255] of char;
WindowsDir:  string;
begin
GetWindowsDirectory(buff, sizeof(buff));
result := string(buff); {Convert to String}
end;

Sorry, you are right that my answer was in error.

I appologize for the inconvienence.  I read that WINDIR stores the windows directory in it, but the place I read that was in error.

whoops, sorry

How about some code on that alona ? By the way the call is Get SystemDirectory ,but something isn't working right .
I need to find a file in system directory and if it's not there to copy it there. Somehow nothing seems to work. Could you help ?

sile, try this code.  It will fetch the Windows System directory, and assign it to SystemDir.  Hope this helps.

var
buff:  array[0..255] of char;
SystemDir:  string;
begin
GetSystemDirectory(buff, sizeof(buff));
SystemDir := string(buff); {Convert to String}
end;
