I have extended the datetimepicker control to incorporate
a ReadOnly property.
I have used the new keyword to implement my own version
of the value property, so that if readonly == true then
it will not set the value of the control and will leave
the checked status of the checkbox to false when a user
selects a new date.
this works fine when using the control on a win2k machine
but if we use it on a win XP box and call

Hi all.
I'm using the Property Grid control in a control to manage a windows service
we have developed here. The windows service runs a set of other jobs that
need to be managed. The control is used to view the state of the running
jobs and schedule new jobs. The control also runs in the context of
Internet Explorer (we do this so the administrators of the jobs can always
receive the latest control). The property grid is used to...

With a Class is there any difference between a readonly property and
function besides having to use Get/End Get.
Are there any performance/resource advantages for either.
Thanks

I have a class named "myclass" and an arraylist containing elements of type
"MyClass". I want to get the value of a property of "MyClass" (a string
type) for one of the arraylist elements.
I can get this using:
dim b as string
b = DirectCast(myarraylist(0),myclass).myproperty
However, I want to use an object to define the type "MyClass" like:
dim C as type = type.GetType(myarraylist(0))

Hi all,
Ok - I guess this one will eventually still end up as a "personal choice"
kinda answer, but I thought I'd run it passed the wealth of knowledge and
experience that's in this group.
Typically when I'm writing my classes I'll have a series of properties which
I set to be read only, I'll then, if I need to write some methods for
setting the values of the class level variables exposed in the readonly
properties.

If I have a class with a public variable, isn't this the same as a
private variable with a property? ie, isn't this:
Public Class MyTest
Public MyVar as String
End Class
the same as this:
Public Class MyTest

I've tried following the simple instructions to be able to use MyServices
within C#...Add a project reference to Microsoft.VisualBasic.dll and add:
"using Microsoft.VisualBasic.MyServices;" to the code module. After that, I
expected to be able to use MyClock or MyComputerInfo, but none of the "My"
stuff appears in the intellisense. I've tried rebuilding (after adding the
reference and the using statement) and still no luck.

Perfect. That makes more sense then calling a method to run the Stored Proc
and return the value in the read only properties "Get" method because then
it would be running that everytime someone wants to use that value.
Instead, run it once at object instantiation, then set it once to the
private variable, then the read only properties get method "gets" it from
there when it is requested.. Makes a lot more sense...
Thanks!

My question is concerning IOC containers and Dependency Injection. The
scenarios I'm struggling to get my head around is with regard to

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:

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,...
