现有一个程序要得到机器的返回值,其返回值为一个固定格式的字符串
首位为标示返回值种类的符号,例“=”、“#”等
中间为返回内容,为数字或数字及字符的组合,例“123.5”、“01DATA”
末位为回车符(0DH)请问:
如何取得返回值中字符数字组合中的数字部分,例:“=+0012.N/”(末位的/为回车符),要求分别取得正号和数字0012.明天回来结贴,谢谢。

Dim a As String
Dim b As Stringa ="=+0012.N/"
b = Mid(a, 2, Len(a) - 1)
MsgBox b'b就是你要的数据End Sub
''48~57 (数字0~9 )
''65~90 (大写字母A~Z)
''97~122 (小写字母 a~z) Dim intChar As Integer
intChar = Asc(strChar)
Select Case intChar
Case 48 To 57, 65 To 90, 97 To 122
CheckChar = True
Exit Function
Case Else
CheckChar = False
End Select
End FunctionPrivate Sub Command1_Click()
Dim i As Integer
Dim strAll As String
Dim strGet As String
strAll = Text1.Text
For i = 1 To Len(strAll)
If CheckChar(Mid(strAll, i, 1)) Then
strGet = strGet & Mid(strAll, i, 1)
End If
Next
Text2.Text = strGet
End Sub========================如果你还要增加其他字符
只要修改CheckChar即可
Dim strValue As String
strValue = "=+0012.N/"
Dim i As Integer
Dim s As String
Dim strEnd As String
For i = 1 To Len(strValue)
s = Mid(strValue, i, 1)
If IsNumeric(s) = True Or s = "+" Or s = "-" Then
strEnd = strEnd + s
End If
Next
MsgBox strEnd
End Sub
Dim temp As String
temp = Mid(Text1.Text, 1, 1)
Select Case tempCase "="
'数字
MsgBox Val(Mid(Text1.Text, 2, Len(Text1.Text) - 1))
Case "#"
'字符串
MsgBox Mid(Text1.Text, 2, Len(Text1.Text) - 1)
End Select
