Question

vb 自定义数据类型

我想用一个数据类型，就像boolean型一样包含true和false两个状态，现在，我需要的是包含三个状态的变量，如何去定义呢？
比如说，布尔变量可以这样
Dim xx as boolean
dim yy as boolean
xx=true
yy= false
现在，我需要：
dim xx as mydatetype
dim yy as mydatetype
dim zz as mydatetype
xx=true
yy=false
zz=middle 'middle 是自己创建的状态

菜鸟问题，谢谢啦

用Enum定义枚举类型

membername [= constantexpression]
membername [= constantexpression]
