Problems with querybypoint and shapelib

[Frederico Lucca]

Hello Humberto,

I'm still having problems with my application.
I suspect that the problem is the method where I call queryByPoint(), but I
don't know why.
What about that problem with delete(), I remember that you and others have
talked about.
Can you give me some light?

Best regards,

Fred
