Hi all,
I have some custom collections (ArrayList of custom Objects) and I want to
display them using typical Windows form controls (DataGrid, Combo). What
should I do to expose them as valid datasources to these controls? What if I
want that these collections work with Visual Studio on design time in order
to allow me easy create grid columns on design time? Can you point me to
some examples?
Thanks in advance

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...

All,
I have written a very simple custom composite control that includes a
control of type System.Web.UI.WebControls.Table.
The control renders fine in run time, but for some reason, it does not
render properly in design time.
In design time it renders something like this:

We are designing a WinForm application ( three tiered)
There is a debate in our group as to whether we should pass datasets or
our custom collections from business layer to the user interface layer.
The data is stored in memory (fetched from DB only once). The
collection is dynamic in the sense that it can change.
My personal opinion is that using dataset makes you code take much more
memory than a custom collection. Datasets have...

Hello everyone,
I have created a custom component and one of its properties is a class
object with it's own properties. During runtime, I can assign values to the
class object properties just fine. However, when attempting to assing
default values as designtime in the propertygrid, nothing is working on the
class object. I know that I am doing it wrong, any ideas what it is?
Thanks in advance

I have included below virtually all the code to a control I'm trying to

This is an example of the aspx code that gets parsed correctly. For some

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,...
