Hi All, After the installation of PetShop 3.0, every time my machine reboots, Windows Explorer runs "C:\Program Files\Microsoft\". Any ideas? I checked \Startup, \\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, etc. but found nothing with it... Did I miss anything?

Warnar, I cannot see your images attached. You should verify these procedures first : - Check your database server, has mspetshop db already installed ?. If not, then this is your db issue. - You may have to uninstalled the previous version first,and then reinstall the newest version.

Hi, I've noticed that in the ASP.NET PetShop Sample, there are 2 WebServers running IIS in LoadBalancing. The presented architecture requires 2 ISA Servers, one for each WebServer running IIS. Is it necessary to have 2 ISA Servers? Why not just 1 ISA Server for the 2 WebServers in LoadBalancing? If we have the configuration with 2 ISA Servers, can we have just 1 EntryPoint for the application (PetShop Sample)?

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.

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,...
