I am trying to replicate the functionality of
DataTextField/DataValueFields in an extended DropDownList control that
I have created in order to provide a third value for each ListItem.
This value will be stored in a client-side array currently as that is
where it is required. Now to the problem.
I've overriden the DataBind Method of my DropDownList and within it
have added the code below:

I use the following code to get an array containing the fields

I have adapted the following code from the MSDN help for PropertyInfo
SetValue. In the original code, the structure MyStructure is defined as a
class MyProperty, and it works as expected. There is also a minor change in
class Mypropertyinfo, which I have commented out.
When using a structure, however, the second call to GetValue returns
"Default caption". Can anyone tell me why, and how I can make this work?

PropertyInfo props = obj.GetType().GetProperties();
foreach (PropertyInfo p in props)
if (p.PropertyType is ValueType)

I get a warning that says p.PropertyType will never be ValueType....and it
was right.
After stepping through it the types are "System.Boolean" etc...

I'm using Reflection to iterate over the properties and fields of an
arbitrary object. For non-indexed properties it's
pi.GetValue(theObject, Nothing) for VB, or pi.GetValue(theObject, null)
for C#
For indexed properties, instead of Nothing (null) you pass an array of index
values.
OK, no problem so far.

I am writing a very generic DumpObject(object Obj) method.
I can easily GetType() and GetType().GetProperties().
I can easily PropertyInfo.GetValue(Obj, null) for scalar variables.
The problem is arrays or collections which require this syntax:
PropertyInfo.GetValue(Object, Object index)

Hi,
I need to invoke .getvalue and .setvalue on fieldinfo and propetyinfo
objects. Even though they're both derived from MemberInfo, they don't
share those two methods. I've finding myself writing the following
types of structure over and over. Is there something I'm missing? Or
some 'funky' 3.5 delegate/lambda expression way of doing this?
Thanks very much in advance,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
