You must have an array of them.
This is the critical information that I needed. Apparently, in C++, indexing pointer variables (whether they are strings, records, classes, or whatever) is just a matter of tacking on an index: SomeComplicatedRecord[i].SomeMethod >C arrays look > different. Are you sure you don't have an array? Are you sure > you _shouldn't_ have an array? I guess I really *SHOULD* have an array in Delphi. Otherwise, how can I cycle through each member? This requires converting the type from a pointer to a non-pointer type. And of course, much of the code that references the variable will also need to be rewritten. I've begun to do this but, am wondering how to deallocate the memory for an Array of Record. This record, 'Was_a_pointer', is declared in the 'Private' section of a class. In the Destructor, this is how it was deallocated: // C++: delete[] Was_a_pointer; When I try to deallocate this array, I get all sorts of errors. None of the following work: Was_a_pointer := NIL; FreeMem(Was_a_pointer); @Was_a_pointer := NIL; Was_a_pointer.Free; Dispose(Was_a_pointer); Is an array that is declared in a class automatically disposed of when the class is destroyed? If not, what is the proper way to free memory allocated to arrays of records? Thanks soooo much for all your wisdom and insights!
