As you can see in the syntax of Do Loop While, it will first run the statement once and after that, it will go to the condition and test it, and if that condition is true, it will start the loop and continue it while the condition is true. Example to Understand the DO Loop While...
For Loop For Each Loop Do While Loop Do Until Loop Wend Loop (obsolete) In this post, I will explain all these VBA Loops with examples. But before jumping into the topic, let's understand what a loop is and why it is used. What is a loop, and what are its uses? VBA FOR LOOP ...
As opposed to the do until loop, the Do While loop will perform the loop until the criteria become false. In other words, the Do Loop will perform while the criteria are met. It looks to be the exact opposite of the do until loop. If we were to use the exact same macro example ab...
Do [while件] 句 Loop 这段代码表示:当while条件为True时,就会循环执行语句,直到while条件为False为止,这时Do While循环语句终止,程序执行流程跳转到Loop关键字后方的语句继续执行下去。 下面以一个简单的例子说明: Sub DoWhile_example() Dim i As Integer Do While i < 10 MsgBox Do while循环的第& i + 1...
使用Do...Loop语句无限次地运行语句块。 这些语句在条件为True时重复,或者直到条件变成True时重复。 条件为 True 时重复语句 可通过两种方式使用While关键字检查Do...Loop语句中的条件。 可以在进入循环之前检查条件,也可以在循环运行至少一次后检查该条件。
可以使用Do...Loop语句去运行语句的块,而它所用掉的时间是不确定的。当条件为True或直到条件变成True时,此语句会一直重复。 直到条件为 True 时重复语句 当使用While关键字去检查Do...Loop语句中的条件时,可以有两种方法。可以在进入循环之前检查条件式,也可以在循环至少运行一次之后才检查条件式。
VBA Do While循环实际上是一种条件循环,即语句会一直执行,直到指定的条件不成立为止。例如,下面的程序将通过Do While语句从1打印到5:Sub Example1()Dim x As Integer x = 1 Do While x <= 5 Debug.Print x x = x + 1 Loop End Sub 上面的程序首先使用变量x声明变量,并将其初始值设置为1,然后...
Do[语句] [Exit Do] [statements]Loop[{While|Until}condition] “执行循环”语句语法具有以下部件: Part说明 条件可选。 为“True”或“False”的数值表达式或字符串表达式。 如果条件为Null,那么条件将被视为“False”。 statements当或直到条件为“True”时重复的一个或多个语句。
Sub InfiniteLoopExample() Dim exitLoop As Boolean Do MsgBox "这是一个无限循环。请关闭消息框以结束。" exitLoop = True '假设用户关闭了消息框 Loop While Not exitLoop End Sub ``` 在这个例子中,循环会一直执行,直到`exitLoop`变量被设置为`True`。 4. `While...Wend`循环:类似于`Do...Loop`循...
This process can be performed using thedo until or do whilefunction. However, under do loops, the user needs to perform three additional steps manually: Declare a counter variable Initialize (store an initial value) in the counter variable ...
