Problems calling a Windows API

Hi.... I'm trying to call a Windows API this way:

WritePrivateProfileString('Setup', 'Port', @S, 'Monitor.ini' );

where S is a string[1]. Obviously, this call is bad because it doesn't work. How can I do it to pass a string variable as parameter? If I use only S, compiler doesn't compile the code. Please Help!!!

Thanks in advance,
Jaime

You need to write:
WritePrivateProfileString('Setup', 'Port', pChar(S), 'Monitor.ini' );

See example on:

I looked at the example and I realized that I could use TIniFile component to access the Ini File. I used:

var ArchIni : TIniFile;

and then

ArchIni.Create( 'Monitor.ini' );
ArchIni.WriteString( 'Setup', 'Port', S );

When I run this code, compiler sends the warning:
'Variable ArchIni might not have been initialized'
and when I close the program, I got an exception Error on the application.
How can I solve it?

Thanks again in advance
Jaime

ArchIni:=TiniFille.Create( 'Monitor.ini' );
ArchIni.WriteString( 'Setup', 'Port', S );
.

ArchIni.Free;
