Hi,!
Yeah Mofset I figureout the problem of a pointer with 0 length.. but how
should I write my function so?
How could we declare a char that we dont know the max size? Iam really
confused. I tough declaring a char *NextSearchPtr will dynamicly increase
the size... ????
Damn transition to vb to pure c++ is a nightmare but c++ was so powerfull!
gimme clue!
Thanks for your help! (sorry for my bad english)

NextSeachPtr is a pointer with no memory allocated. It's pointing at random
data (or more likely NULL). Thus when you copy data to it it will segfault.
That is why it is working with the [3000], you are allocating 3,000 bytes
there.
