The output string is :- popeye

That's what you wanted huh?

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 here

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

Re: string help whats wrong with this code?

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;

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?

char *Input = new char[1024];

or

char Input[1024];

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

Pass an Metafile from the container to an ActiveX control

Hi,

I would like to pass a metafile from the container to my ActiveX control ( developed using ATL), how can I do that ? ( I always passed bools or number ... Frown | :-(

).

Thanks, Bye !

You can encapsulate your metafile in an object supporting the interface IDataObject. ATL

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_atl_idataobjectimpl.asp">IDataObjectImpl</a>

class serves this purpose.

Hola Joaquin !

Do you know where I can find some examples about that issue ? ( IDataObjectImpl). I found samples about getting things from the clipboard, but what I would like to do is from the client app, pass an Metafile to the my ATL/server.

Thanks !, Hasta luego !

How to detect memory leak in VC++

I am using VC (MFC also) to develop programs under Visual Studio as IDE. Could anybody here exlain how to used Visual studio to detect memory leak?

In debug mode, you can use

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_crt__crtmemdifference.asp">_CrtMemDifference</a>

and related functions (in <crtdbg.h>) to check for memory leaks caused by C run-time library allocations (malloc, realloc and new).

GOOD LUCK!

C Runtime library for addressing memory, look up _CRT in the MSDN index. Unfortunately, they don't account for all the memory. Beyond that, BoundsChecker by Numega is probably the most popular tool for this purpose.

Hope this helps
