Question

I made a datatable with 2 columns a transactionTime column and a numberOfTransactions column. I made the table with the pre-defined transaction times and want to add the number of transactions from an XML file. I have gotten through the XML file and want to add the data to the correct row. Here is the function:

Function AddRow(ByVal timeOfTransaction As String, ByVal numberOfTransactions As String, ByRef dataTableOfTransactions As DataTable) As String


    Dim row() As DataRow = dataTableOfTransactions.Select("transactionTime = timeOfTransaction")

    If row(0) IsNot Nothing Then
        row(0)("numberOfTransactions") = numberOfTransactions

    End If
    Return Nothing

End Function

When I run this it overwrites the first element in the table’s numberOfTransactions coloumn. I know it has to do with the “transactionTime = timeOfTransaction” part but I can’t seem to get it to read timeOfTransaction as a reference to a string instead of a literal. Any help would be much appreciated. Thanks!

You need to write something like this :

Dim row() As DataRow = dataTableOfTransactions.Select("transactionTime=#" & timeOfTransaction & "#")

But be careful with your date/month or month/date format, it depends of your regional settings.
