Hi all,

I got some troubles retrieving documents for sequence points in call
to ISymUnmanagedMethod::GetSequencePoints. It returns valid offsets,
lines and columns, but nulls for documents.

I'm using this API from managed (C#) code via COM Interop. Actually
if I change type of the docs parameter to IntPtr[] I can see that it
actually fills it with some valid pointers so it might be a marshaling
error.

WBR, Oleg Stepanov

Hi Oleg,
It does indeed sound like a marshalling issue. You should make sure
that the interface you've defined for ISymUnmanagedDocument is correctly
defined.

You can also just use the managed symbol store wrappers defined in
System.Diagnostics.SymbolStore (reference ISymWrapper.dll).
