Public Shared Properties, where are they stored?

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :ASP.Net

I have the following code in a class in which I call from different pages, I wanted to know where this info is being stored at as I can see it from different pages.

Public Class SampleProperties

    Public Shared _OrderID As Integer

    Public Shared Property MagicOrderID() As Integer
            Return _OrderID
        End Get
        Set(ByVal value As Integer)
            _OrderID = value
        End Set
    End Property

End Class

Also, is this saved on the browser session? IIS? will whatever being set from 1 user be affected by every other user on the site?11

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.


Use a WPF control in a Public Shared function



I am trying to write a program that uses a button on one window to alter a control in another window.  I have a Public Shared Sub declaration in the window I wish to alter, but I cannot put in the code to make the changes to the control (error is "Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class").  How can I get around this so I can change a control's properties from within a Public Shared function?


Public properties of collection derived classes are not deserialized in REST wcf service

WCF Tip: Using Properties in Service Contracts

you'll notice all of the Service Contracts are implemented with interfaces containing only methods. For the longest time I thought that's all that was supported, until I thought about it a little more. In C# land, properties are simply wrappers around a get method and set method, so why wouldn't we be able to use properties in a service contract? Well the answer is we can.

Automatic vs Explicit Properties

If the reason that motivated the change from automatically implemented property to explicitly implemented property was to change the semantics of the property then you should evaluate whether the desired semantics when accessing the property from within the class are identical to or different from the desired semantics when accessing the property from outside the class.

Dependency Properties

When you begin to develop appliations with WPF, you will soon stumble across DependencyProperties. They look quite similar to normal .NET properties, but the concept behind is much more complex and powerful

Xml File Methods and Properties

Method and Properties of XmlTextWriter class:
The XmlWriter class is a base class that outputs an XML data structure. It has methods to sequentially write XML elements in a proper hierarchy to create an XML file or other types of output streams. The System.Xml namespace provides support for the XmlWriter. It must be imported to the ASP.NET page with the directive

<%@ Import Namespace="System.Xml" %>

The XmlTextWriter

XmlWriter is an abstract class that is implemented as an extended XMLTextWriter class. The XmlTextWriter writes a sequence of XML nodes one element at a time. Output can be written to an XML file, although other streams of output data can be produced. It can create a new file or overwrite an existing file. Its non-cached writing techniques provides very fast generation of an output stream.

Send Email from SQL Server Express Using a CLR Stored Procedure

One of the nice things about SQL Server is the ability to send email using T-SQL. The downside is that this functionality does not exist in SQL Server Express. In this tip I will show you how to build a basic CLR stored procedure to send email messages from SQL Server Express, although this same technique could be used for any version of SQL Server.

If you have not yet built a CLR stored procedure, please refer to this tip for what needs to be done for the initial setup.

Inserting rows via stored procedure and under certain conditions


I'm using Dynamic Data with Entity Framework in VS2010.

Let's say my table has these fields:

PersonID (FK)
LocationID (FK)

Hypothetical scenario (it's easier for me to explain this way, so just bear with me for now)... But let's say each row in the table represents "how many items were sold by such-and-such employee at such-and-such location," where location and person are foreign keys which are referencing other tables.  Basically, there should be no more than a ONE row which has a particular combination of Person and Location.  Makes sense?

So, when inserting new rows using my Dynamic Data app, the insert form displays editable fields for Person (dropdown), Location (dropdown), and Items Sold (textbox).  How do I prevent users from inserting another row into the table containing an already-existing combination of Person and Location?   How do I displaying useful feedback to them in the event that they DO attempt to do this?

I have several thoughts about this, but since I'm new to Dynamic Data, I'm not sure which way to go.  For example:

Option 1:  Use "cascading dropdowns" approach in the insert form and only pull in the "allowed" combinations of the two dropd

Creating A Stored Procedure Which Searches Team Names
