I have to display all days base on a date range. For example my date range is "January 1, 2011" to "February 28, 2011". Now what i want is to display all the dates base on that range, what i meant about "display the dates" is like this.
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 :)
I have a calender which highlights the selected date from the database. It currently highlights the start date only...I would like it to highlight the range of dates (start date - send date)[code]I think the query and where statement used is not pulling through the correct information but not entirely sure where or how to correct it ...

My current code as follows: Function GetCurrentMonthData(ByVal startdate As DateTime, _ ByVal enddate As DateTime) As DataSet
I have a form where there are two date and time picker as StartDate and EndDate. I use MS Access database. I want to search all data within StartDate and EndDate and display it on my list view.
I'm getting the following error: [ArgumentOutOfRangeException: Value to add was out of range. Parameter name: value] System.DateTime.Add(Double value, Int32 scale) +7657639 System.DateTime.AddDays (Double value) +19 ...
The line from which this error originates has the following code: expires = Now.AddDays(30) It occurs irregularly and irreproducibly. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative. It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Culture settings perhaps?
Lets say i had a label with 9/6/2010 11:59:99 that was selected from the month calendar control, is there anyway to determine how many days are from the present days date to the selected end date?
Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.
UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:
Here's my code:
Private Sub CheckForOverlap(myMonth As Messages.MyMonth) Dim am As New MyMonth() Dim amCollection As Messages.MyMonthCollection
I am trying to get a list of dates from a provided StartDate and EndDate in my database, and use these dates to link to dates in a database (to display another variable on the y-axis of the chart) and to populate the x-axis of a chart (with the list of dates). Is it possible to get a list of dates in VB and pass them into a chart this way?
I am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.

Is there a method or function that I can use to get the number of days between a start date and end date? I tried using Timespan, but I was noyt able to convert the value to a string. What I am doing is I have 3 text boxes. 1 with start date value user will set using a calendar. And another with end date set using a calendar.And the 3rd text box is being used to display that difference between the two dates.

The looping part i have no problem with, and the system date calculation also i know how to do. The problem call the date from the startDate column to do the calculation.

How do you select records based on the next 10 days from todays date.For eg:Lets say I want to select records based on ReqDt = today + 10Select * from Sample1 where reqdt <= today + 10
I read that .Net has no function equivalent to Excel's "Workdays" function, which adds a specified number of workdays to a startdate, including an array of holidays. I managed to find a function that adds the number of workdays to the startdate, but I am having no luck telling the function to add a day to the start date for each holiday within the date range. I've pasted a self-contained function below. Every time I compare the result against the Excel result, it's not adding up.
Private Function CalcEndWD_5wkd(StartDate As Date, WD As Integer) As Date Dim Holidays(23) As Date Holidays(0) = #10/5/2012# Holidays(1) = #11/12/2012# Holidays(2) = #11/21/2012# [Code] .....
how to manipulate the dates to determine which date will be 30 days more then the datetime control I have on my form. i need to take the chosen date from the DateTime control, and determine what date it will be in 30 days. Eventually I will use this process to search through the database to print monthly reports.
