> How can I check if a String has a format such as "hh:mm"?

(untested):

    AnsiString string = "02:00";
    short hour, minutes;
    if( sscanf(string.c_str(), "%02hd:%02hd", &hour, &minutes) != 2 )
    {
        if( (hour < 1) || (hour > 23) || (minutes < 0) || (minutes > 59) )
            // wrong format
    }
    else
        // wrong format

> I want to be able to check if the inserted time is right.

You could alternative just assign the string to a TDateTime and see if the
conversion fails.
