TCP .net server and VB6 client problem

Hello, I'm trying to make a socket connection from a legacy VB6 app to a .net
TCP server. The VB6 app is tested and works well against a VB6 server, but
when I try it against my .net server it just opens the socket and instantly
closes the connection right before the next instruction so I can't send the
data.

The .net server receives the connection (I see that it creates the socket)
but never receives the data. Anyone has any idea about what is happening?

This works fine. - User selects an option on the listbox and, using the OnChange, I

After a server created cookie is processed on the client I want it removed, cleared, or expired in the javascript block but have been unable to do this. If I set a cookie value in the server code behind and don't use a domain then I can not change or remove that cookie's value on the client. If I subsequently create the cookie again in the codebehind then I actually end up with TWO cookies with the same name in the response. The cookie...

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...

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,...
