String (variable-length) 10 bytes + string length 0 to approximately 2 billion String (fixed-length) Length of string 1 to approximately 65,400 1、String变长内存结构 10字节是如何分配的?通过网上的一些资料和自己猜测: 变量本身占用4个字节,用VarPtr可获取地址p VarPtr那个地址p保存的值,指向了字符的...
Strings are an important part of any programming language. A string is basically any kind of saved text. You can do a number of operations on strings including concatenation, reversal, sorting, finding string length, deriving substrings, searching for specific character in a string and more. Tod...
" & RTrim(" adfasdfsd ") Len(String) '返回给定输入字符串的长度,包括空格 msgbox("Length of var1 is : " & Len("sdf sdfsd ")) space(number) '用特定数量的空格填充字符串 msgbox("aaa" & Space(2)& "bbb") StrComp(string1,string2[,compare]) '比较两个给定字符串后,返回一个整数值。
2 在与用户定义的数据类型中的可变长度字符串一起使用时，Len 无法确定所需的实际存储字节数。3 Use the RightB function with byte data contained in a string. Instead of specifying the number of characters to return, length specifies the number of bytes。4 与在双字节字符集语言中一样，将MidB函数用...

String*n (fixed-length) The length of string is between 1 to 65,526. 1 to approximately 64K (216– 10) characters. Empty A single distinguished value corresponding to the reserved identifierEmpty An implementation-specific bit pattern Error ...
ThePublicstatement can't be used in a class module to declare a fixed-length string variable. Use thePublicstatement to declare the data type of a variable. For example, the following statement declares a variable as anInteger: VB PublicNumberOfEmployeesAsInteger ...
Remarks The GetFileVersion method returns a zero-length string ("") if pathspec does not end with the named component.Note:The GetFileVersion method works only on the provided path string. It does not attempt to resolve the path, nor does it check for the existence of the specified path....
