Compare The Modify Date Of A File Vs The Current System Date?

Oct 22, 2008

I'm trying to compare the modify date of a file vs the current system date. I've found an MSDN article describing how to get the modify time of a file:

Dim infoReader As System.IO.FileInfo
infoReader = My.Computer.FileSystem.GetFileInfo("C: estfile.txt")
MsgBox("File was last modified on " & infoReader.LastWriteTime)

This gest the Date and Time, but I want just the Date not the time.

Dateinterval With Work Day - Compare The Date That Is Entered With Today's Date

Jun 6, 2011

I need to compare the date that is entered with today's date minus some number of work days.

I used dateinterval.day, but that is the actual day, not the work day. i don't see a "simple" way to get work days.

For example, my number is 3, so i want 3 work days (M-F) not 3 days.

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.

The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.

For what it's worth, the relevent part of the query is:

Select [Date Created] From MyWorksheet

Sep 28, 2010

I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)

Compare The Date Fields?

May 26, 2010

I have 2 Textboxes with Date/Time in them. I want to test if one is less than the other, here is my current code

Dim StartTime1TextBox As TextBox = TryCast(FormView1.FindControl("StartTime1TextBox"), TextBox)
Dim EndTime1TextBox As TextBox = TryCast(FormView1.FindControl("EndTime1TextBox"), TextBox)
If Not [String].IsNullOrEmpty(StartTime1TextBox.Text) Then

[code]....

However if I enter an Start time of 9:00 AM and an End Time of 5:00 PM this triggers the isvalid=false because 5 is less than 9. Doesn't look like it's comparing the date and time just number.

Compare To Date Ranges?

Feb 21, 2012

I am developing a billing application to help out the billing lady who has been doing our billing by hand. I am essentially done�. Except for one class of customer I can�t wrap my head around. Nuts and Bolts:

1.Data comes from a table that shows Storage id, customer id, Billing Start date, Billing end date.

2.I am kicking the data back out to a table and I�ll build her a nice little crystal she can run.

Problem:We rent storage space. If multiple customers use the same storage then they will split the cost of the daily fee. If there is 3 customers they each pay a third etc. This seems simple but If Customer 1 starts on 1/1/12 and ends 1/10/12 she pays 10 days. If Customer 2 comes in 1/3/12-1/9/12 they will split 7 days. If Customer 3 comes in only on 1/9/12 then they will all pay a third on that day. Now imagine this across 600+ storage units and 1000+ customers and each customer using multiple storage at any given time.

My biggest issue is I don�t know how to express how we do that calculation by hand programmatically. By hand process and how I figure I am eating the elephant: Find every Customer that has used the Space in the billing period -Determine the unique storage numbers that were used during the billing cycle kick the results to a storage table on an access database. I am using a table because I figured it would be less of burden for the application then a list or array.

Determine where there is overlap - Use �FOR� to cycle through the orginal data table using the unigue. Here is where I am stuck. How do I compare the dates in a way to determine which customer is using it when compared to the others. Obviously i can determine the difference in dates between the start and end. It is getting the applicaiton to recognize the dates are with in the other dates. here is kind of what I was thinking obviosly this doesn't work I am just using the format so don't crush me too bad because I code like a caveman.

Dim CustomerDifference as time span
Dim UniqueStorage as Integer
Dim Customer as string

VS 2008 US And UK Date Compare?

Jun 17, 2011

My collegeue and I have been searching on the net a hell of a lot for a problem he is facing and we so far have been unable to find a resolution.He has an Access Database where one of the columns is of Date format. This date is in UK style (as defined by the Operatins System)

In his application there is a datetime picker which the user picks from he then wants to select * from the access database where the dates match but because the DateTime Picker is giving a US Format date (i.e MM/dd/yyyy) and in the database its UK (i.e: dd/MM/yyyy) its not finding a match and returning no records.
