Question

I need to create a table. One column of the table schedule date and time. I am new to C++/CLI. The only way that I know how to find the relate the date and time is using

 System::DateTime newDate

I need to find out the schedule date in each row and sort them by the happening soon. How can I compare each DateTime object with the current time and find out which happen the soonest?

Thanks

It’s quite unclear what exactly do you want, but assuming that you have a collection of objects with a Date property, you can do something like this:

IEnumerable<SomType^>^ items = …

DateTime now = DateTime::Now;

SomeType^ result = nullptr;

for each (SomeType^ item in items)
{
    if (item->Date > now && (result == nullptr || item->Date < result->Date))
        result = item;
}

That being said, it’s probably not a good idea to learn programming in C++/CLI, I think it would be much better if you used C#, unless you have a good reason for C++/CLI.
