FileRead is called from the DoWork event in the C# app. Just left out. As to the second...

In the wrapper.h:
delegate bool UpdateProgressDelegate(unsigned int, Object^);


Wrapper::FileRead(....)
UpdateProgressDelegate^ upd = gcnew UpdateProgressDelegate(UpdateStatus);
GCHandle gch = GCHandle::Alloc(upd);
IntPtr ip = Marshal::GetFunctionPointerForDelegate(upd);
CB_UpdateStatus update = static_cast<HD_CB_UpdateStatus>(ip.ToPointer());


Then calling the native function:
Result = NativeFileRead(DataSize, Data, UpdateStatus &context);


Is that what you are suggesting? How does the native callback return percentcomplete through a BGW? I still need a native callback that takes the two args. Not real clear then
