Answer 1

I had similar problem. Below fixes worked for me

1) Don't hold your connection to sheet. Instead open connection read data and close the connection immediately.

2) If you are using managed code in the unmanaged application then consider using object of managed type instead of pointer(using gcnew) and use Stack Semantics to make sure that memory is cleaned up when object goes out of scope.
