vb读取csv文件，在文本框中输出

例如：csv文件内容为：Date,$Time,PV1,PV2,PV3,PV11,PV12,PV13,PV4,SP,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,YOUYA,VZ1,V2,V3,V4,V5
03/23/12,17:40:26,102,102,102,102,103,102,97,105,16.8,17.5,22.1,26.3,21.1,21.4,22.3,19,22.3,23,25.4,22.8,49668,0,0,0,10.091,843
03/23/12,17:45:26,110,110,110,110,109,110,105,112,17.1,17.8,23,28.2,22.1,22.5,23,19,22.3,23.2,25.8,22.8,47544,0,0,0,10.091,790
03/23/12,17:50:26,118,118,118,118,117,118,113,120,16.8,18,24,30.5,23.2,23.7,24,19.5,22.5,23.5,26.8,23,45141,0,0,0,10.091,807
03/23/12,17:55:26,125,126,126,126,126,125,121,128,16.8,18,24.9,32.9,24.4,24.7,25.1,19.7,22.5,23.7,27.5,23,45407,0,0,0,10.091,813
03/23/12,18:00:26,133,133,133,133,134,133,128,135,17.1,18.3,26.1,35.2,26.1,26.1,26.1,20,22.3,24,28,23.2,46939,0,0,0,10.091,820
希望再文本框中输出同样无逗号的相同行、列的内容

我变得程序
Private Sub Command6_Click()
Dim TextLine
    Dim TextString
    Dim SplitStr As Variant
    Dim SplitStr2 As Variant
    Dim i As Long, j As Long
    Dim s As String
    Dim m, n As Integer
Dim a() As String
Open "DATAFILE.CSV" For Input As #1 ' 打开文件。
Do While Not EOF(1) ' 循环至文件尾。
        Line Input #1, TextLine ' 读入一行数据并将其赋予某变量。
        Debug.Print TextLine ' 在调试窗口中显示数据。
        If TextString = "" Then
            TextString = TextLine
        Else
            TextString = TextString & ";" & TextLine
        End If
    Loop
    Close #1 ' 关闭文件。

    SplitStr = Split(TextString, ";")
    m = UBound(SplitStr)
    For i = 0 To m
        SplitStr2 = Split(SplitStr(i), ",")
        n = UBound(SplitStr2)
        ReDim a(0 To m, 0 To n)
        For j = 0 To n
            a(i, j) = SplitStr2(j)
            Text1.Text = Text1.Text + a(i, j) & " "
        Next j
         Text1.Text = Text1.Text & vbCrLf
    Next i
End Sub
如果csv文件内容过多，运行特别慢甚至会死机 Open "DATAFILE.CSV" For Input As #1
Text1 = Replace(Input(LOF(1), 1), ",", " ")
Close #1 这位版主你太厉害了，如果这样：csv文件为下面这个（一个小的为例，实际会有28列，很多行），
Date,$Time,PV1,PV2,PV3
03/23/12,17:40:26,102,102,102
03/23/12,17:45:26,110,110,110
03/23/12,17:50:26,118,118,118
03/23/12,17:55:26,125,126,126
03/23/12,18:00:26,133,133,133
我做了五个复选框：分别为 Date $Time PV1 PV2 PV3，选中哪个，就只从csv中提取那一列，并从文本框中显示输出？
所以我编的哪个吧csv文件内容给了一个二维数组？应该怎样呢？
十分感谢同时还想把这个文本框中内容存到EXCEL中去？给定指导吧，我刚接触VB不久

用Split函数切割
比如：
Dim arr() As String
s = "03/23/12,17:40:26,102,102,102"
arr = Split(s, ",")
那么arr(0)就是"03/23/12"
arr(1)就是"17:40:26"
...
结合你的CheckBox判断就可以了。本帖最后由 bcrun 于 2013-12-01 07:36:22 编辑
