[RESOLVED] 32 bit versus 64 bit

Thinking of upgrading VB5/6 to use 64 bit.

I assume there are 64 bit API's?

Questions:
1) Will I need to update all my API calls to 64 bit?
2) If so, is the change for "MOST" APIs as simple as changing 32 at the end of the API to 64 -- do a simple search and replace?
3) Does VB5/6 play nice with 64 bit or am I better staying with 32 bit?

Thanks
David
