vb.net - compilation error when trying to call overloaded constructor

Last Modified: 2014-08-26
Hi Experts,

Here is a sample of my code.

Public Class clsLicenceSentinel

    Private mvarintProgramNumber As Integer

    Public Sub New(intProgramNumber As Integer)

        mvarintProgramNumber = intProgramNumber

    End Sub

    Public Sub New(strProgramNameAndMajorVersion As String)

        Dim intProgramNumber As Integer

        Select Case strProgramNameAndMajorVersion
            Case "APSDS3"
                intProgramNumber = 1
            Case "CIRCLY6"
                intProgramNumber = 2
            Case "CIRCLY3"
                intProgramNumber = 3
            Case "CIRCLY4"
                intProgramNumber = 4
            Case "APSDS4"
                intProgramNumber = 5
            Case "CIRCLY5"
                intProgramNumber = 6
            Case "APSDS5"
                intProgramNumber = 7
            Case "HIPAVE1", "HIPAVE5" '20050208
                intProgramNumber = 8

        End Select

        'call the constructor 
        Call New (intProgramNumber)  '<<<< gives "Type Expected" error

    End Sub

End Class

Open in new window

I am trying to call the overloaded constructor (see 3rd statement from the end).
But this gives a compiler "Type Expected" error.

try :

'call the constructor 


Open in new window


Thanks, sethi.


Thanks, Paul Jackson, for your suggestion.

I tried that, but it gave this error:

Constructor call is valid only as the first statement in an instance constructor.

I have now found a workaround to get my code working - by putting all the code that is common to the two contructors into a single sub.

Glad I could help. Thanks.
Leigh, that method is the correct way to do it, its not a work around.
