StyVB,
Here is a code sample for a transformation script to illustrate the idea. The Row.Line is the input column that contains an entire line of a text file. This line is taken and split into an array by the comma delimiter. The first time we see the line, it is a header with column names. A boolean flag is used to detect the header condition and we save the column names in a variable. For every subsequent row, we iterate through the column names and match them to an output column that has been defined for the script, assigning the value parsed from the file into the correct column. Using this method, the order of the columns in the text file is irrelevant.
Code Snippet
Dim Line As String = Row.Line
Dim LineTokens As String() = Line.Split(","c)
If IsHeader Then
HeaderColumns = LineTokens
IsHeader = False
Else
' match input columns to output columns
With Output0Buffer
.AddRow()
For i As Integer = 0 To HeaderColumns.Length - 1
Select Case HeaderColumns(i)
Case "Time"
.Time = LineTokens(i)
Case "Probe1"
.Probe1 = LineTokens(i)
Case "Probe2"
.Probe2 = LineTokens(i)
Case "Probe3"
.Probe3 = LineTokens(i)
Case "Probe4"
.Probe4 = LineTokens(i)
End Select
Next
End With
End If
