IEnumVARIANT_Next

[GCuser99]

Hi Cristian, I noticed that in twinBASIC, the scope of IEnumVARIANT_Next is set to Public. What does it do? I did not see it listed in the methods and properties descriptions.

Working great so far with LibJSON.

Thanks,

Mike

Hi Mike,

In VBA, I avoided doing an actual EnumVariant object by using dummy ones from a blank Collection. All I did was to manipulate pointers so that the dummy objects run fast (asm) code on the dict's data. That does not work in TB because Wayne chose to store indexes, instead of pointers, inside his implementation of EnumVariant. So, IEnumVARIANT_Next is a fake callback that is called because I replace the virtual function address inside Wayne's EnumVariant to call my function. Obviously, a bad trick - I was planning to do a proper TB implementation at some point with a proper EnumVariant Object but never got to it, maybe next year.

Also, see Wayne's comment in #34

Thx! Looking forward to the twinBASIC version. Then hoping that FastDictionary and FastJSON together get added as a tB package!
