byte[] buffer = new byte[inStream.Length];
inStream.Read(buffer, 0, buffer.Length);
outStream.Write(buffer, 0, buffer.Length);

an event/method/property defined in a base class? For example,
consider:
WebBrowser Events:
Event: Click
Description: This event is not supported by this control. (Inherited
from WebBrowserBase)

Getting AppSettingsReader to use app.config file changes at runtime Posted by Matt Adamson at 4/25/2006 12:12:15 PM Guys,
When writing unit tests for our assemblies we'd like to change configuration
values at runtime for some tests i.e. to test all code paths are executed.
e.g. one method would create a test with a value set to true and the next
test method would set it to false.
I can set the values in ...more >>
VB.Net evaluates 'if' conditions unnecessarily? Posted by Tim_Mac at 4/25/2006 10:23:38 AM hi,
in c# i can run the following code without risk of
NullReferenceException:
if(textNode != null && !String.IsNullOrEmptytextNode.InnerText))
the reason it is safe to run is because if the first condition is
false, then the CLR will not bother to examine further conditions

Force Rejit of a method Posted by Dinis Cruz at 4/20/2006 12:21:05 AM Hello, Is there a way to force the ReJit of a method?
One of the demos that I do in my 'Rooting the CLR' presentation is to do
real time MSIL patching.
The problem is that I need to apply the 'patches' before the JIT has
occurred, unless (hence my question) I am able to dynamically either:

Major memory leak in sos.dll under .NET Framework 2.0 Posted by Andreas Suurkuusk at 4/12/2006 5:27:01 AM I have tried to use sos.dll together with the WinDbg debug engine to perform

Reference type size in heap Posted by Amir Shitrit at 4/9/2006 10:07:02 AM Why does a reference type occupies 8 bytes in memory?
I assume that 4 bytes are needed to identify the object's type (or for the
virtual table), but what about the remaining 4 bytes?
Second, why does the size of a structure that has only one byte in it, is
rounded to 4?...more >>
