This article mainly introduces the ways of vba program flow control, the article is very detailed, has a certain reference value, interested friends must read it!

The way of vba program flow control is: selection control (branch control), loop control and sequence control. VBA is a structured programming method, which requires that the program can only be composed of three basic control structures: sequence, branch and loop.

There are three ways of VBA program flow control: sequence control, selection control and cycle control, which also correspond to three basic control structures of structured programming.

The programming of sequential structure is the simplest, as long as the corresponding statements are written according to the order of solving the problem, and its execution order is from top to bottom.

The selection structure is used to judge the given conditions, some conditions are judged according to the result of the judgment, and the flow of the program is controlled according to the result of the judgment.

The loop structure can reduce the workload of repeated writing of the source program, and can be used to describe the problem of repeatedly executing a certain algorithm, which is the program structure that can give full play to the computer's specialty in program design. The loop structure can be seen as a combination of a conditional judgment statement and a turn-back statement.

Sequential structure:

The sequential structure is to execute sentence after sentence from beginning to end until the last sentence is executed. As shown below

Select structure

After arriving at a node, it will decide which branch to execute in the following direction based on the result of a judgment. As shown in the following figure

Cyclic structure

The loop structure has a loop body, and the loop body is a piece of code. For the loop structure, the key is to determine how many times the loop body is executed according to the result of the judgment.
