Tr
MyConn.Open(
Dim rdr As SqlDataReade
rdr = SPretDate.Execu teReader(
rdr.Read(
Dim FlightDate As String = (rdr.GetSqlDate Time(0).ToStrin g

'if flightDate is not Null the
FlightDateArray List.Add(Flight Date
'End i

I also wanted to minus 1 date from another to get the number of days gap

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,...
