how to make a boolean default to True in web service
in [VB.NET]
|
From: cj2 on 8 Jul 2008 15:04 In the code below I want when this web service is first published for the boolean Running.running to be True. It seems to default to false. How can I make this default to True? Once the web service is running and I call it with "start" it works fine as coded. I just don't want to have to call it with start the first time. Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Imports System.Data.Odbc ' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. ' <System.Web.Script.Services.ScriptService()> _ <System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _ <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <ToolboxItem(False)> _ Public Class Running Public Shared running As Boolean End Class Public Class CashOnly Inherits System.Web.Services.WebService Dim result As String <WebMethod()> _ Public Function CashOnly(ByVal act As String) As String If act = "stop" Then Running.running = False result = "stopped" ElseIf act = "start" Then Running.running = True result = "started" elseIf IsNumeric(act) And act.Trim.Length = 10 Then If Running.running Then Dim myDs As New DataSet Dim myOdbcConnection As New OdbcConnection("Driver={Microsoft Visual FoxPro Driver};" + _ "SourceType=DBF;" + _ "SourceDB=c:;" + _ "Exclusive=No;" + _ "Collate=Machine;" + _ "NULL=NO;" + _ "DELETED=NO;" + _ "BACKGROUNDFETCH=NO") Dim myOdbcCommand As New OdbcCommand("select flag from \\fileserver\i\probill\act_frau.DBF where act = '" + act.Trim + "'", myOdbcConnection) myOdbcConnection.Open() result = myOdbcCommand.ExecuteScalar.ToString myOdbcConnection.Close() Else result = "Try again later" End If Else result = "Invalid request" End If Return result End Function End Class
From: Steven Cheng [MSFT] on 8 Jul 2008 22:30 Hi Cj, From your description, you are wantting to set some initial value for a shared/static variable of your webservice class , correct? In .net, there are several ways you can initialize a static/shared class member: 1. Class can have a static constructor which can help you do some initialize tasks for the entire class(not specific to an particular instance). #9.3.2 Shared Constructors http://msdn.microsoft.com/en-us/library/aa711965(VS.71).aspx e.g. ============== Class YourClass Private Shared running as Boolean Shared Sub New() running = True End Sub .................. End Class =================== 2. Or you can directly assignt the initial value at the variable's declaration place. e.g. =================== Class YourClass Private Shared running as Boolean = True ................... ===================== Hope this helps.

From: cj2 on 9 Jul 2008 08:44 Steven, I had tried your second example but it didn't work--it does now. I must have had something else wrong at that time too. Thanks for confirming that that should work in web apps too.
