vb 将计算出的数据添加到txt文件中

Private Sub Form_Click()
Dim reg As New RegExp
reg.Pattern = "[\d\.]+"
reg.Global = True: reg.IgnoreCase = True: reg.MultiLine = True
Dim textline As String
Dim temp() As String  '第n行的x和y
Dim temp1() As String  '第n+1行的x和y
Dim temp2() As String  '第n行的时间
Dim temp3() As String  '第n+1行的时间
Dim distance() As String
Dim timeInterval() As String
Dim speed() As String
Open "e:\data.txt" For Input As #1

ReDim temp(1)
ReDim temp1(0)
ReDim temp2(2)
ReDim temp3(0)
ReDim distance(0)
ReDim timeInterval(0)
ReDim speed(0)
Do While Not EOF(1)
Line Input #1, textline
temp(0) = reg.Execute(textline)(3)    'x
temp(1) = reg.Execute(textline)(4)    'y

If (UBound(temp1) >= 1) Then

distance(0) = (temp(0) - temp1(0)) ^ 2 + (temp(1) - temp1(1)) ^ 2

Print textline, distance(0)
End If
ReDim temp1(1)
temp1(0) = reg.Execute(textline)(3)
temp1(1) = reg.Execute(textline)(4)
Loop
Close #1
End Sub

Private Sub Form_Load()

End Sub

计算结果如下：

在要保留原数据（前三列）的情况下，怎么把计算出来的结果distance（最后一列是计算结果distance） ，写入txt的最后一列？？？？？？？

txt中原数据如下：
14:04:16     31.0042     121.19409
14:04:57     31.004078     121.191348
14:05:08     31.00401     121.190088
14:05:25     31.0039     121.187448
14:05:28     31.003878     121.18694
14:05:39     31.00384     121.18541

最终想要的txt中的数据格式是：
14:04:16     31.0042     121.19409    7.53344799998821E-06(手工录入最后一列，哭)
14:04:57     31.004078     121.191348    1.59222400000498E-06(手工录入最后一列，哭)
14:05:08     31.00401     121.190088    6.98169999999739E-06(手工录入最后一列，哭)
14:05:25     31.0039     121.187448    2.5854799999964E-06(手工录入最后一列，哭)
14:05:28     31.003878     121.18694    2.34234400000757E-06(手工录入最后一列，哭)
14:05:39     31.00384     121.18541
