Please assist in explaining this asp.net error message when converting string to datetime

Question

Function:

Public Shared Function ConvertoDate(ByVal dateString As String, ByRef result As DateTime) As Boolean
        Try
            Dim supportedFormats() As String = New String() {"MM/dd/yyyy"}
            result = DateTime.ParseExact(dateString, supportedFormats, System.Globalization.CultureInfo.CurrentCulture, System.Globalization.DateTimeStyles.None)

Date String

Dim FlightDateArriveString As String = (FlightMonthArrive.SelectedValue.ToString & "/" & FlightDayArrive.SelectedValue.ToString & "/" & "2010")

*ConvertoDate(FlightDateArriveString)*

The error message is given by the line above ^ and says:

"Arguement not specified for parameter result of public shared function ConvertoDate (datestring as String, ByRef result as date) as Boolean"

Answer 1

Where are you putting the result? Your ConvertToDate takes two paramaters: the string to convert, a DateTime reference to place the converted value and returns a boolean to indicate whether it was successful.

Answer 2

You need to pass a second parameter to the ConvertoDate function

Dim MyResult as DateTime
ConvertoDate(FlightDateArriveString, MyResult)

Answer 3

You need to declare a variable to hold the result:

Dim result As DateTime
ConvertoDate(FlightDateArriveString, result)
