Was considering the System.Collections.ObjectModel ObservableCollection<T> class. This one is strange because
it has an Add Method which takes one item only. No AddRange or equivalent.
the Notification event arguments has a NewItems property, which is a IList (of objects.. not T)
My need here is to add a batch of objects to a coll...
Is there an advantage to dynamically attaching/detaching event handlers?
Would manually detaching handlers help ensure that there isn't a reference remaining to a disposed object?

Most restrictions and tricks with windows forms are common to most programmers. But since .NET 3.0 there is also WPF available, the Windows Presentation Foundation. It is said that you can make "sexy applications" more easy with it and with .NET 3.5 SP1 it got a good speed boost on execution.
But on the other side a lot of things are wo...
Visually both of the following snippets produce the same UI. So why are there 2 controls..
Snippet1
<TextBlock>Name:</TextBlock>
<TextBox Name="nameTextBox" />
Snippet2
<Label>Name:</Label>
<TextBox Name="nameTextBox" />
(Well I am gonna answer this myself... thought this is a useful tidbit I learnt today from Programming WPF)

Edit: Let me completely rephrase this, because I'm not sure there's an XML way like I was originally describing.
Yet another edit: This needs to be a repeatable process, and it has to be able to be set up in a way that it can be called in C# code.
In database A, I have a set of tables, related by PKs and FKs. A parent table, with chi...
I am new to all the anonymous features and need some help. I have gotten the following to work:
public void FakeSaveWithMessage(Transaction t) {
t.Message = "I drink goats blood";
}

This is related to the this question and the answer maybe the same but
I'll ask anyways.
I understand that we can start managed executables from the network from .NET
3.5 SP1 but what about assemblies loaded from inside the executable?
Does the same thing apply?

Ok, so there has to be a way to do this... no? If not I'd love some ideas.
I have two repeaters and an image inside an update panel along with some AJAX dropdowns with link buttons to the left. I want to update the data inside the update panel as fast as possible as values are selected from the dropdowns.
What do you think would be t...
I'm using int as an example, but this applies to any value type in .Net
In .Net 1 the following would throw a compiler exception:
int i = SomeFunctionThatReturnsInt();
if( i == null ) //compiler exception here
Now (in .Net 2 or 3.5) that exception has gone.
I know why this is:
int? j = null; //nullable int
if( i == j ) //this s...
Hello,
A project I'm working on at the moment involves refactoring a C# Com Object which serves as a database access layer to some Sql 2005 databases.
The author of the existent code has built all the sql queries manually using a string and many if-statements to construct the fairly complex sql statement (~10 joins, >10 sub selects, ~1...
Is there a way to auto discover a specific WCF service in the network? I don want to config my client with the address if this is posible.

Some 4 years back, I followed this MSDN article for DateTime usage best practices for building a .Net client on .Net 1.1 and ASMX web services (with SQL 2000 server as the backend). I still remember the serialization issues I had with DateTime and the testing effort it took for servers in different time zones.
My questions is this: Is t...
I've created a seperate assembly with a class that is intended to be
published through wmi. Then I've created a windows forms app that
references that assembly and attempts to publish the class. When I try to
publish the class, I get an exception of type
System.Management.Instrumentation.WmiProviderInstallationException. The

Have been trying out the new Dynamic Data site create tool that shipped with .NET 3.5. The tool uses LINQ Datasources to get the data from the database using a .dmbl context file for a reference. I am interseted in customizing a data grid but I need to show data from more than one table. Does anyone know how to do this using the LINQ D...

2, Create a Setup project that installs just the single executable from the Windows Forms project.
3, Run that installer and it always says that it needs to install .NET 3.5 SP1 on the mac...
I have a repeatable business process that I execute every week as part of my configuration management responsibilities. The process does not change: I download change details into Excel, open the spreadsheet and copy out details based on a macro, create a Word document from an agenda template, update the agenda with the Excel data, creat...
What's a simple way to combine feed and feed2? I want the items from feed2 to be added to feed. Also I want to avoid duplicates as feed might already have items when a question is tagged with both WPF and Silverlight.
Uri feedUri = new Uri("http://stackoverflow.com/feeds/tag/silverlight");
XmlReader reader = XmlReader.Create(feedUri.Abs...
If I were to want to create a nice looking widget to stay running in the background with a small memory footprint, where would I start building the windows application. It's goal is to keep an updated list of items off of a web service. Similar to an RSS reader.

I have a FlowDocument in a standard WPF application window where I have some text, and in this text some hyperlinks and buttons.
The problem is, if I put this FlowDocument inside anything except a FlowDocumentPageViewer the hyperlinks and buttons are disabled ("grayed out").

In JavaScript:
encodeURIComponent("©√") == "%C2%A9%E2%88%9A"
Is there an equivalent for C# applications? For escaping HTML characters I used:
txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]",
m => @"&#" + ((int)m.Value[0]).ToString() + ";");
But I'm not sure how to convert the match to the correct hexadecimal format t...
