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...
Public Function GetStringPixelHeight(text As String, fontName As String, fontSize As Single, Optional isBold As Boolean = False, Optional isItalics As Boolean = False) As Integer Dim font As New StdFont Dim sz As FNTSIZE 403 Forbiddenfont.name= fontName font.Size = fontSize font.Bold = ...
In this program the variables are declared as type string. The length of the String variable is calculated using the Len(string length) function. Then the variable is concatenated with a space character. The string length is recalculated. The first and second string length value is compared. I...
Public Function Len(ByVal Expression As String) As Integer 此函数接受一个字符串作为参数。如果该函数成功地计数了字符数(通常是这样),它将返回一个整数。下面是一个例子。 Sub Exercise7() Dim Item As String Dim Length As Integer Item = "excelperfect" Length =...
FunctionRIGHT(ByVal str As String,ByVal Length As Integer)As String FunctionRight(ByVal str As String,ByVal Length As Integer)As String 这两个参数都是必需的。第一个参数是原始字符串,第二个参数是从字符串右侧开始计算的字符数。 字符串的中间子字符串 ...

Manipulate strings to get concatenation, a reversed order or the result with added/removed specified string-character(s).
constname此為必要動作。 常數的名稱;遵循標準變數命名慣例。 type選用。常數的數據類型;可能是Byte、Boolean、Integer、Long、Currency、Single、Double、Decimal(目前不支援) 、Date、String或Variant。 針對每個宣告的常數使用個別的As類型子句。 expression此為必要動作。 常值、其他常數或包含所有算術或邏輯運算符的任何...
