Hi,
I was working on an MDI application using Visual C++ 2005 .NET. In a
child window, I have an instance of DataGridView control. If I open
several child windows, they all work fine.
However, if I close one of the child windows and try to add a row to
DataGridView control that is active, I get an error

the table) it raises the datagridview dataError event. ...

Has anyone tried wrapping the DataGridView control itself as a custom
Cell/Column control. So that I can have a child DataGridView appear
in a column of a parent DataGridView so that the columns/rows of the
childdren can be edited like a grid on the parent rows grid.

separate splitter panels. I would like it to show up kind of like how

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,...
