Dim cellValue As String Dim firstCharacter As String cellValue = Range("A1").Value '假设要获取A1单元格的值 firstCharacter = Left(cellValue, 1) '获取第一个字符 MsgBox "单元格开头的字符是:" & firstCharacter 在上述示例中,我们首先将A1单元格的值存储在变量cellValue中,然后使用Left函数将第一个...
ActiveCell = Number & "的ASCII字符是" &Character End Sub 结果如下图3所示。 图3 字符串长度 字符串的长度是它包含的字符数。为了查找字符串的长度,Visual Basic语言提供了一个名为Len的函数。其语法是: Public Function Len(ByVal Expression As String) As Integer ...
SubExercise5()Dim Character As String Dim Number As Integer Number=114Character=Chr(Number)ActiveCell=Number&"的ASCII码是"&Character End Sub 结果如下图2所示。 图2 除了查找数字的ASCII等价值外,Chr函数还可用于在程序中应用某些行为。例如,Chr(13)和Chr(10)的组合可为表达式断行,相当于vbCrLf运算符。
