64 bit programming errors and how to avoid them

[Modelworks]

Here is a good read on errors that can occur when programming for 64 bit applications . Many of the examples show how the same program works fine for 32 bit but when used for 64 bit has errors.

pretty standard stuff really. Some of the situations that he demonstrated would be pretty hard to get into.

I could sum it up as "Don't assume variable size".. (well, and also don't use depreciated functions).
