定义i为integer变量，对i赋值65535，运行代码出错。出错原因：integer的范围是 -32768~32767之间，65535>32767,超过integer变量的范围了，因此报错。如果，我们在处理数据的时候，循环遍历的最大次数，超过了i（integer变量）的范围，那么代码同样会报错，如下例子：解决方法：声明整数型的变量，同一使用Long类型，long的...

integer是整型long是长整型它一直是不同，它们开辟的内存空间是不同的。它们有自己各自的数据范围，细节百度一下。
VBA数组(六)动态数组 大家好,前面已经介绍过了如何声明数组、数组赋值、静态数组和数组函数等等知识点,本节主要讲解动态数组。 动态数组的定义 如果在声明数组不确定数组的大小,先不固定数组的大小,而在程序在运行时使用Redim语句重新定义数组大小即为动态数组。(而如果声明数组时即确定数组大小即为静态数组。) 声明动...
在Visual Basic .NET 中,某些数据类型(如Variant、Integer、Long、Currency以及其他类型)已经更改或过时。例如,VBA 中的Integer等效于 Visual Basic .NET 中的Short。另外,VBA 中的Long等效于 Visual Basic .NET 中的Integer。 固定长度字符串 由于更改后允许 Visual Basic .NET 数组和结构(先前称为用户定义类型)完...
