Lập trình VBA trên Microsoft Excel

Writing code is easy. Writing good code is hard. So what is good code anyway? Generally, we think of the following attributes:
1. The code works (no bugs) 2. The code is documented 3. The code is maintainable 4. The code runs quickly
Unfortunately, meeting these goals is often time-consuming and difficult. To help with this process, we at FMS have compiled a list of things that we use on a daily basis—tips and techniques that make it easier for us (and you) to write code that comes closer the lofty goal of defect-free maintainable code.
Coding style and practices are a heated topic among developers, approaching an almost religious fervor. The contents of this article should not be construed as the final word—rather, it is a exposition of the standards we at FMS have found useful in the job of writing code. There are guidelines contained here that you may not agree with, which is fine; don't follow them. However, it is important to understand the concepts involved, so let’s dive right in.
