Hi,
I just meet this error today, and now I have solved it .
The error occurs the following code:
HBufC8* iBufC8 = HBufC8::NewL(850);
When I pay attention to the parameter HBufC8*& aBufferName of CImageEncoder::DataNewL function, it's a *& type. So the buffer will be allocated in the function of CImageEncoder::DataNewL , then assign the start address to the aBufferName, which is reference of income pointer. So, if use a pointer which is already point to memory space on the heap to the CImageEncoder::DataNewL function, will lead to memory leak and the program will exit with panic.
So, the solution is very simple, Just overwirte the following code:
HBufC8* iBufC8 = HBufC8::NewL(850);
to:
HBufC8* iBufC8 = NULL;
Thank OK!

Hey howardchan

Even I have the same problem. I think the problem is with the buffer

HBufC8* iBufC8 = HBufC8::NewL(850);

Plz let me know If you have solved this problem.

Thanks in advance

That API properly working

but i could not say how to solve that problem

, i just say one tip you should study base C++ about pointer

sorry, but i hope this tip and information helpful to you.

Sorry , maybe my English isn't well. The panic I said now just means the leave I said last time .
Yes , as you said , my ap will leave with the notification "Progarmme closed my ap name" . Is this leave or panic ? Anyhow , the notification will appear and ap exit .
And I can't trap any useful data for my ap .
Really thanks deeply for your help , didster .

Panic?? You can't trap panics, only leaves.

If your app is panicing, the whats the panic code? Does it show "Program closed, my app name"?

Have to tried trapping the call to DataNewL to see what it's leaving with?

Maybe the output buffer isn't big enough?

Hi, didster, thanks so much for your reply .
But as your advice, I try to trap the panic . But not any useful result . By the S60 SDK's Help, the API DataNewL(), it seem that it won't return any panic when certain error occur .
Could you give me some other effective advice ?
Thank you in advance .
