Public Function finnOrdrenr() As Integer
 
        Dim forbindelse As New System.Data.OracleClient.OracleConnection
 
        forbindelse.ConnectionString = "user id=****;password=***;data source=*****"
        forbindelse.Open()
 
        Dim kommando As New System.Data.OracleClient.OracleCommand("select ordrner from", forbindelse)
 
        Dim dataleser As OracleClient.OracleDataReader
        dataleser = kommando.ExecuteReader()
        Dim onr As Integer
        While dataleser.Read()
            onr = dataleser.GetInt32(0)
        End While
 
        dataleser.Close()
        forbindelse.Close()
 
        Return onr
    End Function

msgbox (finnOrdrenr())
or just write

you will have to fetch that result in a variable for your further use. for example

Dim varonr as Integer = finnOrdrenr()
