-
i have this code on a button and it is ment to find the last { and then read the text in front of it and output it to edit4? s = "this would be the text{ste}"; string l = "{"; a = s.rfind(l); Edit3->Text = a; int a; String s; for (int i = a;i<=s.Length();i++){ Output = Output + i; } Edit4->Text = Output; and in the end output should = ste on this example

The code snippet I posted is a demonstration of an easier way to achieve what you are attempting to do.

The input string was :- abc{ghj{popeye}jjj The output string is :- popeye That's what you wanted huh?

thanks i just got it!:)

thanks i just got it!:)
i have just got an error wit the line: y=strchr(t,'}'); on running it i changed the code a bit to: char abc[1000]; char *Input; strcpy(abc,Input); char *t,*y; t=strrchr(abc,'{'); y=strchr(t,'}'); if(y) *y=0; cout << t+1; HidPass = t; does this have anything to do with it?

You need to do one more pointer validity check.
char abc[1000];
char *Input; //better alloc some memory here
strcpy(abc,Input);
char *t,*y;
t=strrchr(abc,'{');
if (t) y=strchr(t,'}');
if(y) *y=0;
if(t) cout << t+1;
HidPass = t+1;//remember the plus one hereNish was here, now Nish has gone; He left his soul, to turn you on; Those who knew Nish, knew him well; Those who didn't, can go to hell. I like to :jig: on the Code Project Sonork ID 100.9786 voidmain www.busterboy.org

sorry about all this but now it has a problem with HidPass = t+1;//remember the plus one here:(( :((

Is HidPass declared as a char* and if so, has it been allocated some memory using new or malloc? By the way if the answer is "yes" to the above question replace that line with :- if(t) HidPass=t+1; Nish Nish was here, now Nish has gone; He left his soul, to turn you on; Those who knew Nish, knew him well; Those who didn't, can go to hell.

i dont get any errors now it just does not work? HidPass does not equal anything?

you said char *Input; //better alloc some memory here how do i do that? and i know why it is not working! cos as soon as Input becomes a char it screws up and does not equal what it should?

Input cannot be made in to a char as it no longer equals what it should so as a AnsiString it equals: save that{ste} and as a char it equals:ÈóI
