动态输入数目 子vi

[Orange125]

大家好！请问如何编写输入数目不定的子vi？类似于C语言中带有动态输入数目的函数。LabVIEW8.2

Don't quite understand what you want to do... what about Random Number (0-1)? It can be used to produce any Random number with little coding...

你好，首先谢谢你的帮助。可能我的描述不够准确。但是我不是要生成一个随机数，而是编写一个子vi，可以接受动态数目的输入个数。比如此VI可以接受1个输入，2个输入，等等。

thank you for your kindness.but what I want is a vi witch can accept different number of inputs,for example 1,2,or 3 inputs,and so on.The vi you passed to me can produce a random number,I cant understand.

What is(are) the input type(s)?

Are the input(s) of the same type(s)?

[ian_fung]

One way, for taking dynamic data of the same type, is using CSV string...

Thank you very much.The vi is really helpful.I think maybe I can creat an array with all the inputs of the same type,and the subvi accept an array.Then,in the subvi,I can use the Array-size function to get the size of the input array.Thus it maybe also a way for inputs of the same type.

But what if the inputs are of different types?

By the way,how can I get the type of a control ?

[ian_fung]

Cluster, for example, can be Flatten To String, passed to sub-vi , and recovered with Unflatten From String. I maybe wrong but this, however, seems to work only with known cluster (with know set of diff. data type).

Thank you.
