  • Passing data to overridden base method in C#

    - by UpTheCreek
    Bit of a dumb question, but I'm wondering what the accepted way of passing data from back to an overridden base method is in c#. e.g. I guess I could do: class A { int x; public virtual void DoStuff() { Console.WriteLine(x); } } class B : A { public override void DoStuff() { x = 1; base.DoStuff(); } } But is there a better method that for example doesn't require the use of a member variable?

    - by randyc
    I am stuck on how to pass data from one control to another. If I have a listbox control and the Contol Item contains a datatemplate which renders out 5 fields ( first name, last name, email, phone and DOB) all of which come from an observable collection. How can I allow the user to select a listbox item and have the valuesbe stored within a new listbox control?

  • How to build a database from an XSD schema and import XML data

    - by FreshCode
    I have a complex XSD schema and hundreds of XML files conforming to the schema. How do I automate the creation of related SQL Server tables to store the XML data? I've considered creating C# classes from the XSD schema using the xsd.exe tool and letting something like Subsonic figure out how to make a shiny database out of it, but not sure if it's the best way to approach it. Has anyone managed to elegantly import XSD files into SQL Server?

  • select xml data column into flat reporting table

    - by Bernard
    We have a xml column in SQL Server 2008. We need to do reporting off the data in the xml so we're going to select the xml into a flat table. The flat table has columns that correspond to various nodes in the xml. What is the best way to do this using SSIS? Is this a good approach? Or should we just try and write the reports directly off the xml column?

  • FormsAuthentication AuthCookie data type

    - by FreshCode
    Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.
