Hi all, I'm trying to modify an Excel macro in VBA which generates binary files to output in big-endian (for Wii), however I'm not very experienced with VB / VBA, and Googling doesn't really give me much luck. I need to convert Integers (16-bit values) and Longs (32-bit values) into big endian, or at least output them byte swapped. I tried doing some bit shifting and masking as I would in C++, using This Code for shifting, but I keep getting overflow errors when I Or the bytes together. So, my question is; is there a straightforward way to byte-swap Integer's and Long's for outputting to a file and if not, is there a way to use unsigned Integers and Longs to avoid these overflow errors? Cheers, Steve

The easiest way is probably just to dllimport htonl() and htons() from Winsock and call those. (Assuming you're running on a little endian machine anyways.)

Ah, excellent - never thought of that, thanks [smile]

And yeah, I'm running on XP Pro (Little endian)
