Hi,
I'm trying to bind a custom collection class to a data grid, following the
guidelines from the article
http://msdn.microsoft.com/msdnmag/issues/05/08/CollectionsandDataBinding/default.aspx.
The problem is the article is in VisualBasic. I already get the collection
to be recognized as a Data Source by the IDE. It populated the DataGrid
correctly from the fields on the items object of the collection, but I can't
get the DataGrid to...

I'm implementing an IDesignerHost, for the CreateComponent method. The code
below is quite standard. When loading a form, the CreateComponent works
fine. However, when someone choose a control from the toolbox, the Activator
couldn't create the component and returns null in CreateInstance. In what
scenario, Activator.CreateInstance will be failed ?? I only create a
System.Windows.Forms.Label. I've verified the type passed in is correct.

I've authored a custom web component (a non-ui component kinda like a
DataSet) and so far it's working. When my web component is added to the web
form in the designer from the toolbox, the namespace for my component is
automatically added to the using directive of the codebehind. And, the
appropriate assembly is added to the "References" for the Web form's
project.
However, my custom component has a field (initialized to null, and...

Hi,
Is there any way to add the @Assembly reference to the aspx files
programmatically from inside a custom control (when it gets dropped on to
the page from the toolbox)?
I have a custom control - MyControl that implements an interface in another
custom assembly - InterfaceAssembly. When MyControl gets dropped on to the
page and run, it results in a "InterfaceAssembly not found" exception. I am
aware that this can be fixed by...

If you just implement the IComponent interface the class is not displayed as
being one that can be designed. What makes a Component designable? Are
there attriubutes that must be set?

In VS2005, VB 2005, I suddenly can't get at a winform design view. The
application still runs OK, but I can't see the designer.
I'ver rebuilt the solution with no success.
I'm looking for a general strategy for dealing with this problem.
Here is the error text:

Hello,
I had quite the same problem and got further in the right direction
with your suggestions, thanks.
Nevertheless, I have a newer problem which seems to come from the fact
that the
assembly which contains my "SimpleComponentToolboxItem" must be
already referenced

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...

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,...
