I need to trim a string. The string is something like it is below.

Welcome, Brian!

I need to trim that so it only has brian, the name may vary in lenght and there may sometimes be comments after the ! so I will need to trim everything after the ! and then !. I also need to trim the Welcome,. Thanks!

Although what you are describing isn't really a trim function, try the following:

function ExtractName(cStr:string):string;
var
  x : integer;
begin
  x := pos('!',cStr);
  if x >0
  then cStr := copy(cStr,1,x-1);
  x := pos(',',cStr);
  if x > 0
  then cStr := trim(copy(cStr,x+1,999));
  result := cStr;
end;

fullwindowtext := extractname(fullwindowtext);

and I get an error about strings not being compatible with arrays. Thanks

Hi,

this example does the trimming you
want:

var
   MYSTRING, NEWSTRING : STRING;

begin
     MYSTRING := 'Welcome, Brian! abcd';

     NEWSTRING := (COPY (MYSTRING, POS (' ', MYSTRING), (POS('!', MYSTRING) - POS (' ', MYSTRING))));
end;


Greetings, Alex
