I've got an object that is being serialized / deserialized via the XmlSerializer in C#, .NET 3.5. One of the properties (and more in the future) is a collection: List where T is an enum value. This serializes / deserializes fine. We are also using a "default values" mechanism to provide default values for the object, in case the seriali...

Hi, I am subclassing an ItemsControl (let's call it EnhancedItemsControl), and I would like to expose ScrollViewerTemplate dependency property, which would allow the user to optionally specify his own template for used ScrollViewer. I am doing it like this: public ControlTemplate ScrollViewerTemplate { get { return (ControlTemplate)G...
Let's say I create a class "Planet" that can be inherited. One of the purposes of inheriting is to create a template with different default property values. Eg: Public Sub New MyBase.New MyBase.ForeColor = Red MyBase.Name = "Mars" etc. End Sub Now, to stop the defaults serializing in the InitializeComponent method, the...

Both of these generate an error saying they must be a compile-time constant: void Foo(TimeSpan span = TimeSpan.FromSeconds(2.0)) void Foo(TimeSpan span = new TimeSpan(2000)) First of all, can someone explain why these values can't be determined at compile time? And is there a way to specify a default value for an optional TimeSpan obj...

We are performing a database migration to SQL Server, and to support a legacy app we have defined views on the SQL Server table which present data as the legacy app expects. However, we're now having trouble with INSTEAD OF INSERT triggers defined on those views, when the fields may have default values. I'll try to give an example. A ...
Hi! I'm writing a jquery-plugin, that changes a css-value of certain elements on certain user-actions. On other actions the css-value should be reseted to their initial value. As I found no way to get the initial css-values back, I just created an array that stores all initial values in the beginning. I did this with: var initialCSSV...

I found half of the answer here to my question when searching "what is the attribute to set the default value of a User Control property in the designer where you change it and it bolds". However the answer neglects to mention the namespace it is in. Searching through Object Browser yields hundreds of classes/properties with the name D...
I'm refactoring a large amount of code where I have to add an extra parameter to a number of functions, which will always have a value of a member of that object. Something like class MyClass { public: CMyObject A,B; void MyFunc(CMyObject &Object); // used to be void MyFunc(); }; Now, I'd actually like it to read class MyC...
Hi stackoverflow coders, I have an app (since the iPhone its really chic to use this word :-)) persisting its data with Hibernate. The database scheme contains several date fields which can be NULL. I configured Hibernate then to fetch the field value also as NULL. The customer wants to configure these values in case these are NULL. So...
When you define a function in Python with an array parameter, what is the scope of that parameter? This example is taken from the Python tutorial: def f(a, L=[]): L.append(a) return L print f(1) print f(2) print f(3) Prints: [1] [1, 2] [1, 2, 3] I'm not quite sure if I understand what's happening here. Does this mean that...

Is it a good practice to initialize columns that we can know their values in database, for example identity columns of type unique identifier can have a default value (NEWID()), or columns that shows the record create date can have a default value (GETDATE()). Should I go through all my tables and do this whereever I am sure that I won'...
