noob question?

[andreip]

how to copy an unsigned char into a descriptor( TBuf16 or TChar ). can someone help please?

i`ve tryed this but it doesn`t work. i get user panic 9.

TBuf16<256> tPass;
unsigened char pass[32];
	
tPass.Copy(KNullDesC);
for(TInt i = 0; i < 16; i++)
 tPass[i] = pass[i*2] << 8 | pass[i*2 + 1];

what was the error?

what was the error?

no error. it just leave with user panic 9

no error. it just leave with user panic 9

User Panic 9 is raised when the index value passed to the 16 bit variant descriptor Operator[] is out of bounds.

So you should be checking the index you are passing to get the contents inside the for loop.

tPass.Copy(KNullDesC) ensures that the length of your descriptor is 0 bytes, so any possible argument for [] will raise USER 9.
Use

tPass.SetLength(16);

instead.
