How can I recognize/parse the structure of UDT, returned from C dll, if I get the pointer to this structure in a VBA function?
Posted on 2004-10-11
A C dll returns a pointer (lngPointer) to a big UDT structure (appr. 60 primitive types fields, differently groupped), created by this dll. I don't know exactly, what are the fields of this structure and what size do they have. Can I recognize/specify it from VBA code somehow?
In particular, to find the size of the whole structure, and the sizes of all fields, as the follow each other?
