VB读非固定格式的TXT
数据格式：A B C D E中间的空格不一样，怎么用VB读
C里面好像有一个函数可以直接读数据，遇到空格就跳过，不知道VB有没有？
--------------------编程问答-------------------- 读出来，再使用Split拆分？ --------------------编程问答-------------------- 但是它们中间的空格不一样啊，SPLIT只能处理固定的分隔符 --------------------编程问答--------------------
你试了没有？不会啊 --------------------编程问答--------------------
--------------------编程问答--------------------
Option Explicit
Dim strP As String
Private Sub Command1_Click()
Dim intP As Integer
Dim strA() As String
strA = Split(strP, " ")
Text1.Text = ""
For intP = LBound(strA) To UBound(strA)
Text1.Text = Text1.Text & strA(intP)
Next intP
End Sub
Private Sub Form_Load()
strP = "A B C D E"
End Sub
+1 --------------------编程问答--------------------
strp=Replace(strp, " ", "")--------------------编程问答-------------------- --------------------编程问答--------------------
你如果把字符串中的空格替掉之后，那拿什么来区分ABCDE呢 --------------------编程问答--------------------
Private Sub Form_Load()--------------------编程问答--------------------
Dim a, b
Dim i As Integer
a = "A B CD E"
b = Replace(a, " ", "")
For i = 1 To Len(b)
a = Mid(b, i, 1)
Next i
End Sub
while instr(strp," ")>0--------------------编程问答-------------------- 去掉空格再读如何？ --------------------编程问答--------------------
strp=Replace(strp, " ", " ")
wend
Option Explicit--------------------编程问答-------------------- 先用replace删除掉多于的空格，只保留一个空格作为间隔符，然后再使用Split拆分。
Dim strP As String
Private Sub Command1_Click()
Dim intP As Integer
Dim strA() As String
dim s As String
strA = Split(strP, " ")
For intP = LBound(strA) To UBound(strA)
if strA(intP)<>"" then s=s+"["+strA(intP)+"]"
Next intP
msgbox s
End Sub
Private Sub Form_Load()
strP = "A B C D E"
End Sub
比如：
--------------------编程问答--------------------
Sub main()
Dim i As Integer
Dim s As String
Dim arr() As String
s = "a b c d"
'过滤掉多余的空格
Do
s = Replace(s, " ", " ")
Loop Until InStr(s, " ") = 0
'拆分并显示结果
arr = Split(s, " ")
For i = 0 To UBound(arr)
Debug.Print i, arr(i)
Next
End Sub
'*****读取文件表头信息********************************************
Sub ReadFileInfo()
Open MngBaseFileName For Input As #intFilenum
Dim a() As String
Line Input #intFilenum, strline
Deltblank '转到 Deltblank 去除多余空格
a = Split(strline)
v01000 = a(0)
v04001 = a(6)
v04002 = a(7)
Close #intFilenum
End Sub
'*****去除多余的空格********************************************
Sub Deltblank()
Do
If InStr(1, strline, " ", vbTextCompare) = 0 Then Exit Do
strline = Replace(strline, " ", " ")
Loop
End Sub
这是我常用的方法
很管用，如果格式里面还有TAB格式的话可以先替换成空格
--------------------编程问答-------------------- 路过，学习学习…… --------------------编程问答-------------------- 用正则将多个空格替换成一个，然后分割；或者只取非空数据。
'*****去除多余的空格********************************************
Sub Deltblank()
strline = Replace(Trim(strline), Chr(9), " ")
Do
If InStr(1, strline, " ", vbTextCompare) = 0 Then Exit Do
strline = Replace(strline, " ", " ")
Loop
End Sub
--------------------编程问答-------------------- 使用正则表达式不就可以了 --------------------编程问答--------------------
Sub GetStr()
Dim oJs As Object,Str$
Str = "A B C D E F G"
Set oJS = CreateObject("ScriptControl"):oJS.Language = "JScript"
Ojs.eval "function gets{return str.match(/\S+/g,'')}"
Str = oJs.Codeobject.gets(Str)
Debug.Print Str
End Sub
Private Sub Command1_Click()
Dim N As String, i As Integer
Dim R() As Integer
N = "123 33 55 66 77"
While InStr(N, " ")
ReDim Preserve R(i)
R(i) = Mid(N, 1, InStr(N, " ") - 1)
N = Trim(Mid(N, InStr(N, " ")))
i = i + 1
Wend
ReDim Preserve R(i)
R(i) = N
End Sub
补充：VB , 基础类
