Houston, Vin,

Walter,

This gives you a couple of important benefits, including better performance and protection for your source code. But it also means you have less control over how your binaries are compiled, which can be frustrating, especially when you want to hold down the number of files you distribute with your apps.

Hmmm, I was indeed confusing Delphi's standalone EXE files with VB native code that still requires DLLs to run.

However on this matter, compiling to native code is far overrated. In general only 5% overal performance gains can be reached by compiling to native code. Yes, it will make simple calculations a lot faster, but you'll gain no performance when using high level commands like SQL-SELECT, REPLACE, or other DML commands. In the case of formrefreshes, it might depend on the number of P-code lines executed during the refresh.
