Hi all
I've been using the PropertyGrid to allow the user to edit a class object at runtime. The class object contains a custom strongly-typed collection, and I have written a subclass of CollectionEditor to manipulate it, using an EditorAttribute on the collection class to associate the collection with my custom Editor subclass. The Collection Editor has its own little PropertyGrid, which displays the properties of the selected member of the...

I ran the sample application called Petstore from msdn.
Everything went fine until I tested Update button on the
web form to update the database through Datagrid.
I have been searching the web to track down this error,
but none of them really explain this problem/solution
very well.
I tried hard to debug this, but debuggin itself was
impossible.

I'm getting the following error on an EditCommand event. This code is
running on production web farm and the thing is it doesn't happen all the

Sometimes it works the first time in.
I tried to step through the debugger running locally but I can't duplicate it.

Hi all,
I am having an issue with a custom CollectionEditor. My scenario is as
follows:
I have a base type TypeA. I also have a TypeACollection. The TypeACollection
has an Editor attribute of TypeACollectionEditor. This collection editor
derives from the framework CollectionEditor, passing TypeACollection in the
constructor to indicate which type it deals with.
I then have TypeB, which derives from TypeA, but adds specific

Hi all.
There is a challenge question I encountered recently, which says:
"In plain English, there are six different ways when you want to tell someone else about the current time:
It is five past seven.
It is eleven to ten.
It is half past nine.
It is a quarter past eight.
It is a quarter to ten.

Hi,
I have my property editor wich uses the pop up
collection editor for arrays etc,
but i have had to use a generic wrapper for the
elements in some types of collections.
although the editing actually works well,
and I can set the name ok in the primary property editor,
this makes a mess of the type name displayed in the pop up colection editor,
is there any way to change this ?

Hello
As I debug the C# code with a break point and by pressing F11 I
eventually get a message stating:
ContextSwitchDeadlock was detected
Message: The CLR has been unable to transition from COM context 0x17aeb8 to
COM context 0x17abd8 for 60 seconds. The thread that owns the destination
context/apartment is most likely either doing a non pumping wait or
processing a very long running operation without pumping Windows messages.

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

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,...
