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 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 = ...
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 =...
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...

Mid("text_string", 9, 2) 'gives "in" Mid("text_string", 3, 5) 'gives "xt_st" Length or Position The Len(String) returns the length, the number of characters, of the string, including the blank spaces. Len("String Manipulation!!") ...
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...
type可选。 传递给过程的参数的数据类型;可以是Byte、Boolean、Integer、Long、Currency、Single、Double、Decimal(当前不支持)、Date、String(仅可变长度)、Object、Variant或特定对象类型。 如果参数不是Optional,则还可以指定用户定义类型。 defaultvalue可选。 任意常量或常量表达式。 仅对Optional参数有效。 如果类型是...
