Try this:

Code:

var
I,SlashPos:Integer;
MyText:String;
begin
for I:=0 to memo1.Lines.Count-1 do
begin
   SlashPos:=Pos('//',memo1.Lines[I]);//get the pos of '//' in the line
   if SlashPos > 0 then //check if '//' found
   begin //if true get the wanted text and break
      MyText:=copy(memo1.Lines[I],SlashPos,length(memo1.Lines[I])-SlashPos);
      break;
   end;
end;
end;

Thanks HolyBlah. +rep Wink

Wink

But I want to get the text after Myname =
not after //

I edited the code to

Code:

var
I,SlashPos:Integer;
MyText:String;
begin
for I:=0 to memo1.Lines.Count-1 do
begin
SlashPos:=Pos('Myname =',memo1.Lines[I]);//get the pos of '//' in the line
if SlashPos > 0 then //check if '//' found
begin //if true get the wanted text and break
MyText:=copy(memo1.Lines[I],SlashPos,length(memo1.Lines[I])-SlashPos);
//break;
showmessage (mytext)
end;
end;
end;

it works. btw is it possible not to show 'Myname =' on showmessage? Only show the text after 'Myname ='

You can use the Value property for this:

Code:

showmessage(memo1.Lines.Values['Myname ']);
