I've upgraded a vb6 application to vb .net and am having an issue.
whenever I try to set the recordset property of the VB6.adodc object in .net
and run the application I get the error “object reference not set to an
instance of an object”
this is what the code looks like

Hi
I have an application built in VB6. It uses an adodc control bound to
several other controls. After installing the .NET framework, the
application's data-bound controls no longer display the data from the
recordset contained by the adodc control. Has anyone run into this problem?
Thanks

I have a form with an AdoDc control associated to a datagrid.

What is really weird is that if the source is not placed during design time,
during run time the form upon loading will generate an error ("Failed to

I have an ADODC object in my form which populates a datagrid.
I set the coonection string for ADODC at design time.

The lock file which the connection creates persists even after I exit.
This is what I write in form_unload:

Hello folks,

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

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,...
