Never fear, fuzz!

Here you go:  an example straight from the source code of EasyListBox Smile [:)]

    Public Property SelectQuery() As String
        Get
            Return _selectQuery
        End Get
        Set(ByVal Value As String)
            _selectQuery = Value
        End Set
    End Property

There are more attributes than that, but this should get you started.  Basically, the idea is that you store the value in a local (private) variable...although that's not required.  Also, the return value has to be consistent with the property type (e.g. you can't return a string for an integer property).

Could you use:

    Public Property Index As Integer
        Get
             Return dsTravelPointDD.SelectedIndex
        End Get
        Set
             dsTravelPointDD.SelectedIndex = yourintegervariable
        End Set
    End Property

Getting the Result set of a Web Service in to Data Set Directly.
Guys, Have you ever heard that you can access a XML Web service from your .Net application without adding reference to it or without creating a proxy class for it?. There are still ways to consume a XML Web service directly using HTTP GET method. This method is very interesting and I have found when doing some .Net R&D work. Most of the XML web services are support HTTP GET method. That means you can use HTTP GET method to invoke a XML web service to get an output. A XML Web service will accept parameter(s) and generate a XML based output as a result. EX: http://ws....

Web.Config and Settings.settings
Say you have a web application that references a class library.  How can you put values in the web.config file so that the settings.Designer.vb file (in the class library) can access them?  I have just cut and pasted the "applicationSettings" section from the app.config of the class library to the web.config of the webApp, but this does not seem to have worked.E.G.  I have a setting "MyTestURL" in the settings.settings file of the class library. This results in an autogenerated property  "MyTestURL" in the corresponding settings.designer file...

getting forms authentication settings from web.config file
I'm trying to programmatically determine the loginUrl defined in my web.config file. When debugging, I can see that: ConfigurationSettings.GetConfig("system.web/authentication") returns an object of type: System.Web.Configuration.AuthenticationConfig However, this class is inaccessible. Anyone know of any other way to get the authentication mode?? You could try using reflection. Alternatively (and probably better), you can load your web.config file into an XmlDocument and get the relevant attribute using an XPath expression. Something like this sho...

Dynamic Web References in Settings.Settings
Greetings, With ASP.Net in the 1.1. framework, I commonly created web site solutions that contained a project for web pages, and a separate assembly project(.dll) for business objects.  The web project would reference in the business object .dll.  The business object project had an app.config file in which I contained a dynamic reference to a web service (typically for database access).  The reference needed to be dynamic, so that I could change the reference for different deployments simply by changing the entry in the config file.
