How can I read a "drive label" or "volume name" in .NET?
Can you show sample code for reading a drive label or volume name in .NET? I get the sense this requires WMI, but I am loathe to "drop-down" into WMI because it is like dropping down into a string-based SQL query in the sense that certain objects may not exist on certain versions of OSes or the user may not have the right to query certai...

.NET Processing spawning issues
I have an executable that runs instantly from a command prompt, but does not appear to ever return when spawned using System.Diagnostics.Process: Basicly, I'm writing a .NET library wrapper around the Accurev CLI interface, so each method call spawns the CLI process to execute a command.

How can I find the primary key columns of a table using ado.net?
Is there a pure .net way to do this reliably? The solutions I keep finding either require guessing or they have a solution that is specific to a database provider. Usually querying some internal system table to get this information. ...
String Immutability
Does string immutability work by statement, or by strings within a statement? For example, I understand that the following code will allocate two strings on the heap. string s = "hello "; s += "world!"; "hello" will remain on the heap until garbage collected; and s now references "hello world!" on the heap. However, how many strings...

Where do Java and .NET string literals reside?
A recent question about string literals in .NET caught my eye. I know that string literals are interned so that different strings with the same value refer to the same object.

How to block the UI thread from another thread or force a form to run within the UI thread

Try again later" dialog blocking all user interaction until such time that connectivity is regained. I achieve this by at the start of the application starting an instance of a DeviceMonitor class. This class creates ...

I have inherited a application framework from the previous developer where I now work. This framework utilizes multiple parent/child relationships. In many instances parent/parent/child occur.

Convert string to Brushes/Brush name in C#
I have a configuration file where a developer can specify a text color by passing in a string: <text value="Hello, World" color="Red"/> Rather than have a gigantic switch statement look for all of the possible colors, it'd be nice to just use the properties in the class System.Drawing.Brushes instead so internally I can say something...

How do you databind to a System.Windows.Forms.Treeview control?
I'm looking at this control, and it seems to be lacking the standard .net "datasource" and "datamember" properties for databinding. Is this control not bindable? I can write some custom function that populates the treeview from a given data source, I suppose, and embed data objects as necessary, but is that the 'best practice'? Or doe...
