Comparing Difference Between Any Past And System Dates
Mar 6, 2009
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 trying to write a 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 what I've got so far:
Code:
Public Class Form1
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
[code]....
That's what it looks like so far. I was wondering how you can automate the top label so it automatically comes up with the date when the program is run.Plus, I need to know how to display the dates difference (how many days have elapsed between the system date and the user's chosen date) in the bottom label.

I have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.

I am teaching myself VB while creating a basic application I can use at work. Is there something in VB that will calculate a past and future date from a specific date. For instance, an Election Date falls on November 2, 2011. Once this election date is entered I want the program to calculate the reporting dates. The first report due is due exactly 32 days prior to the election. The 30 day post is due 30 days after the election.

For the past day or so, I have been trying to compare values in my SQL server against an actual calendar. I have had mixed luck with this and I have exhausted my limited knowledge. I am looking for a shove in the right direction.
Background:Right now, I have a program that writes a record to a database when the program completes successfully. This time stamp has both the date and time on the SQL box. I want to grab that information and compare it against the basic calendar. I have attached a picture that should help explain things. This is just my test app,

I 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.

How to calculate the difference in months between two dates in C#? Is there is equivalent of VB's DateDiff() method in C#. I need to find difference in months between two dates that are years apart. The documentation says that I can use TimeSpan like:
[Code]...
but this gives me data in Days. I don't want to divide this number by 30 because not every month is 30 days and since the two operand values are quite apart from each other, I am afraid dividing by 30 might give me a wrong value.

In VB2005 I am trying to calculate the number of business days between two dates. I must also account for U.S. holidays (New Year's Day, Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day/Friday after, Christmas Day). If a holiday falls on a Saturday, then the prior day (Friday) is assumed to be a holiday. Likewise, if the holiday falls on a Sunday then the following day (Monday) is assumed to be a holiday.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.

When 2 or more days old from today
then RED
When 1 day old then YELLOW

Dim myDate As DateTime = CType(grdSummaryView.GetRowCellValue(e.RowHandle, "myDate"), DateTime)
Select Case Now.Subtract(myDate).Days
'2 or more days old then RED FLAG

There is a lot of duplication of functions in the My.Computer.FileSystem and System.IO.File namespaces.
So what exactly is the difference between: My.Computer.FileSystem.CopyFile(strSource, strDest, True)
and:System.IO.File.Copy(strSource, strDest, True)
Is there a performance difference? What is everyone's opinion on which which has the edge on read-ability? I personally use the My.Computer Namespace but that is just habit now.
