View 2 RepliesI am trying to find the difference between two dates. The first of the two dates can be changed and when it is changed, the difference between the original dates has to be retained. This means that I have to automatically change the second date to have the same difference in days as it did before, but with a new first date. [code]I have the value of the old date1(currDate) and the new date1 value(newDate). I need to get the difference between these, and then add or minus these days from the endDate.

I'm trying to make this program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date. This is the layout I've created so far, the two date boxes currently show the system date so even if I change the system date, both those boxes will adjust to show it as well. I want to try and make the system date a box without a drop down arrow and so you cannot edit the box at all. The box below is fine how it is as the user can enter any date they desire. And the text box at the bottom needs to show the difference between the system date and the inputted date.

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?

I know that Every year that is evenly divisible by four is a leap year;

Using VB.Net and SQL 2005
Table1
Name FromDate ToDate
Sched1 20091201 20091231
Sched2 20090515 20090613
...,
In table2 i want to add a time for a date between the FromDate and ToDate
Table2
Name Date StartTime EndTime
Sched1 20091201 080000 120000
...,
In my application am using "AddTime" Button. In the click event i want to write a code for adding the time for the dates.When I click ADDTime Button. It should check the max(date) in table2. Then it should show the next date of the max(date) in table2.For Example Select max(date) from table where name = 'Sched1'. It should show the next date means 20091202. because 20091201 Data is there. There is no data in table2 for Sched2, So It should show the StartDate 20090515 from table1.How to make a code or query for this condition?
