dim() 是“dimension”的缩写,用于计算组合类型(可以是列表、矩阵和字符串)的维数。对于列表,它会返回元素总数。对于字符串,它会返回字数。对于矩阵,它会返回一个二维列表,分别是它的行数和列数。 count() 是单纯计数元素个数的函数,属于比较迷惑的黑魔法,建议大家自己尝试一下。它接受的参数可以是函数或程序以外...

A zero-length array is declared with a dimension of -1. For example: VB DimarrZ(-1)AsString You might need to create a zero-length array under the following circumstances: Without risking aNullReferenceExceptionexception, your code must access members of theArrayclass, such asLengthorRank, ...
IsReference Returns a Boolean value indicating whether an expression evaluates to a reference type. LBound Returns the lowest available subscript for the indicated dimension of an array. MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.) ToString Returns a ...

For example, the fol- lowing type of declaration is not supported: Dim MyString As String * 32 Instead, you can dimension the string as a fixed-length array of characters, as follows: Dim MyString(32) As Char Or you can use a special class, VBFixedLengthString, defined in the Visual ...
***Note ***You can dimension the data type of an argument in the function declaration. You can also (and normally should) dimension the data type for the function's return value. In the example above, the function's return value and the argument dtmAny are both dimensioned as the data...
It is not entirely clear how the dimension conditioning influences the composition. By preliminary testing it seems that settingwidth/heightandtarget_width/heightto 4096 tends to generate slightly sharper details. To keep the correct aspect ratio at more extreme image resolution it might be a good ...
