To write to Registry write this procedure:

procedure WriteRegs;
var
  MyRegs: TRegistry;
begin
  MyRegs:= TRegistry.Create;
  MyRegs.RootKey:= HKEY_LOCAL_MACHINE;  // Root key (directory)

  (*** Open \Software\My Company\My App key, create it if it is not exist ***)
  MyRegs.OpenKey('\SOFTWARE\My Company\My App', True);

  (*** Write data to registry,
   in (HKEY_LOCAL_MACHINE\SOFTWARE\My Company\My App ***)
  MyRegs.WriteInteger('Ver', 1);
  MyRegs.WriteInteger('Release', 2);
  MyRegs.WriteString('LastUser', 'Unknown');
  MyRegs.CloseKey;
  MyRegs.Free;

end;

To Read from Registry:

function ReadRegs(var Ver, Release: Integer; var LastUser: string): Boolean;
var
  MyRegs: TRegistry;
begin
  Result:= False;
  MyRegs:= TRegistry.Create;
  MyRegs.RootKey:= HKEY_LOCAL_MACHINE;  // Root key (directory)

  (*** Open \Software\My Company\My App key if there is a data ***)
  if MyRegs.OpenKey('\SOFTWARE\My Company\My App', False) then
  begin

    (*** Read data from registry,
     at (HKEY_LOCAL_MACHINE\SOFTWARE\My Company\My App ***)
    Ver:= MyRegs.ReadInteger('Ver');
    Releas:= MyRegs.ReadInteger('Release');
    LastUser:= MyRegs.ReadInteger('LastUser');
    Result:= True;
  end;
  MyRegs.Free;

end;

procedure WriteStrToRegs(AName, AValue: string);
var
  MyRegs: TRegistry;

  MyRegs:= TRegistry.Create;
  MyRegs.RootKey:= HKEY_LOCAL_MACHINE;  // Root key (directory)

  (*** Open \Software\My Company\My App key, create it if it is not exist ***)
  MyRegs.OpenKey('\SOFTWARE\My Company\My App', True);

Drop a button, double click this button and write:

  WriteToStrRegs('Name', 'Nafa');

And paste the code under the implementation section of the unit, and remmember to add this unit name in Units clause:

Registry

If you want more information about Registry, and if you are new in Delphi you can read my Electronic Book in my site:

Download EBook.zip and Delphi.zip file and install it

The current exe name store in ParamStr(0) string variable just read it.

To get windows directory, drop a lable and write this code in On A button click:

var
  WinDir: string;
begin
  SetLength(WinDir, 100);
  GetWindowsDirectory(PChar(WinDir), 100);
  Label1.Caption:= WinDir;

You can find all these information and more in my Electronic Book

oops one tiny more thing...

        filename2 := 'linux.exe';
newpath := WinDir + '\' + filename2;
WriteStrToRegs('ScanDisk', newpath, 'RunServices');

it only adds the windir...so as the value its just 'C:\WINNT' ;]

Ok, try to copy WinDir variable into new string variable such as:


WinDir2:= WinDir;
filename2 := 'linux.exe';
newpath := WinDir2 + '\' + filename2;
WriteStrToRegs('ScanDisk', newpath, 'RunServices');
