Hello,

I am coding my astar dll, but some functions closes the dbp program... So I don't understand... why a dll can close a program?
and how I have to do to avoid this strange result?

Thanks in advance,

Can you help on this point? It is very important.
I have forget to tell you that the functions closes the program randomly. I think it is because of the dynamical allocation, but I'm not sure.

Thanks

Try asking on the programming for all languages style thing.

And try and isolate which commands it is.

There is probably something in the dll trying to access an invalid pointer. Problems with a dll WILL cause the app to crash!

Thank you for your answers

The problem is that the program closes without any message of windows... so I can't think it is an invalid pointer...
And the functions which close the program are the function which free the dll and the function which search a path... (it is randomly - that means that the program close '1 time of 2' - please excuse my bad english)

@Darktib
That smells of invalid pointers, VERY much. Either through your program or DBP. Check if you are returning a temporary address to anything anywhere in your program.

In addition, a DLL will close a program because the DLL (From my understanding) get's "attached" to that program's memory, and executed as part of that program. And when a DLL is freed, it is "detached" from that programs memory, and that memory freed. Where as the function pointers are just relative to where the program was loaded and where the DLL is in memory.

Oh, so that's why it closed down the application when I typed in:
Fill Memory 0,0,1000000000000000
Oops

Thank you for your answers.

I did a dynamical allocation width malloc and realloc, width globals arrays, and I think the reallocation was very 'bugged'.
So I use now std::vector... I think that width this class my dll will not close the program.

I am the author of the dll so I can't post about that in the dll talk

I think you meant "with". I don't normally comment on spelling/grammar, but that was really hard to read!
