How to Compile High-Quality VB Code
Introduction:
This article describes how to improve the efficiency of VB code execution through some technical means. These methods can be divided into two major parts: encoding technology and compilation optimization technology. The coding technology introduces how to improve code execution speed and reduce system resources consumed by code by using efficient data types, reducing external references, and other programming methods. This article describes how to use the compilation options provided by VB to optimize the final executable files generated during compilation.
Preface
What is an efficient software? An efficient software should not only run faster than software that implements the same function, but also consume less system resources. This article brings together some experience accumulated by the author when using VB for software development, and demonstrates how to write efficient VB code through some simple examples. This includes some techniques that may be very helpful to VB programmers. Let me know a few concepts before we start.
Let code shape once: Many programmers I have come into contact with prefer to write code based on functional requirements and then optimize the code. Finally, they found that they had to re-write the code for the purpose of optimization. Therefore, we recommend that you consider optimization before writing code.
Grasp the relationship between the optimization result and the work that needs to be spent: Usually when a piece of code is completed, you need to check and modify it. When checking the code, you may find that the code efficiency in some loops can be further improved. In this case, many programmers pursuing perfection may immediately modify the code. It is recommended that you modify the code to shorten the running time of the program by one second. If the performance can only be improved by 10 ms, no changes are made. This is because rewriting a piece of code will certainly introduce new errors, and debugging new code will certainly take some time. Programmers should find a balance between the software performance and the workload required for software development, and 10 milliseconds is also an unrecognized difference for users.
Use the object-oriented method whenever possible. The mechanism provided by VB does not fully support object-oriented design and coding, but VB provides simple classes. Most people think that using objects will reduce code efficiency. I personally have some different opinions on this point. The efficiency of Code cannot be simply from the perspective of running speed. The resources occupied by software are also one of the factors to consider. The use of classes can help you improve the performance of the software as a whole, which will be detailed in the following examples.
