32 to 64 bit MSVS compiler issue

[rschultz2112]

Hi folks,

I have a 32 bit vb.net program that calls a 32 bit dll written in native c++ (no .net). As it is, everything works fine.

I want to upgrade it all to 64 bit. (so I can add parallel, multi-threading for multi-core processors).

What is the proper way to set the Configuration Manager to do this? I changed the "Platform" to all x64 and get all kinds of errors. I've tried various combination of settings and my approach just is not working.

Any suggestions? The MSDN libs are confusing as I seem to get conflicting info. There is not really a specific thread that covers exactly what I'm doing, in one place anyway.

Any tips, ideas or forum postings would be greatly appreciated. I will name a Goat after you also.

Best Regards!
Robert.
