I'm using two datetimepicker controls to set the start and end dates for a range of dates I'm searching for.I want to make sure that the start date selected is not greater than the end date. This code works, but it runs the messagebox prompt twice for some reason. I've tried to ignore it from doing this, but it's not working. Can someone tell me what's wrong?
Private Sub dtpStart_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dtpStart.ValueChanged
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?
How can I determine if a varable called "date1" is within the range of variables "date2" and "date3"?
For example, if date1 is 12/31/1999, and dates 2 and 3 are 12/31/2001 and 12/31/1997 (or the other way around), then first date is between the 2nd and 3rd dates.[code]...

Trying to work out if there's a nice way of doing this, preferably in Linq rather than loops, which is what I've done for now.
I want the number of days my Product is active between two dates.
Product has many ProductHistories, ProductHistory has values for DateActive and DateInactive. DateInactive can be null, and often will be, to show that this history is ongoing. Histories won't overlap.
I want to sum the maximum of my startDate or the ProductHistory's DateActive, and subtract that total from the sum of the minimum of endDate or ProductHistory's DateInactive (endDate by default if DateInactive has no value).
Worked example:
Get active number of active days between 2011-01-01 (1st Jan) and 2011-02-01 (1st Feb)
Histories:
Active 2010-12-25 : Inactive 2011-01-05 Active 2011-01-15 : Inactive 2011-01-20 Active 2011-01-25 : Inactive null
I am trying to get my calendar to render with all the dates in my database, using ranges. Only problem is, I got it working fine, but it has shifted everything one day to the future.

im doing an employee attendance monitoring system, and i need to have a search feature which shows an employee attendance record in a given range of dates
I need to figure out whether a certain date falls within a range of dates. For example the date 11/07/97 (MM/DD/YYYY) falls within the following range of dates formatted as shown below:
01-Apr and 31-May 01-Jun and 31-Oct 01-Nov and 31-Mar
am using sql 2005 and vb 2008.i need to compare dates and select matching records betweem a selected date range.say records between 11/13/2010 and 11/20/2010.e.thing is working ok except when it comes to selecting dates between 11/1/2010 and 11/9/2010.this is happening because when am retrieving the dates from database,its being retrieved in the format 11/01/2010 instead of 11/1/2010 and so it reports no records found,and knowing the limits of sql 2005 this is the only way i can retrieve the date. [code]

I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.

I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
Basically, I have a list of dates in a SQL table with some statistics next to each of them. I want to compare the dates in the table with a certain date I choose. However, my dates in my table are stored as Varchar(50) (and have to be). Apparently I can convert the date in the table into date type but I don't know. Does anyone know how? My current code can be seen below.
I have a order item form with a datagrid I want to add dates to different rows i.e. if the 1st row i order a cheese sandwich in that row I am able to insert a date in the correct cell. I want to be able to insert dates in the other rows with different order items. I have this code below and I want to do a loop back for it. [Code]
We would like to compare a date from the db with current date. Here is what I have tried so far: 'Obtain current date Dim curdate As String = Now.ToString("yyyy") 'Now compare curdate with date from db called eventdate. Event date is of dateTime datatype. If drv("eventdate").ToString = "" And Year(drv("eventdate").ToString) = curdate Then
I'm having some trouble. I have an sql statement to update some rows to an Access DB I enter a date like 01/08/2009 (1st Aug 2009) and it saves to my DB as 08/01/2009 (08th Aug 2009 but still 01 Aug if it were mm/dd/yyyy format)
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.
i have two DatePickers on form and I want filter between two dates. So when i click search in lsitview display the dates between can anyone tell me how to deal with?
I have 2 textboxes, txtStartDate.Text and txtEndDate.Text, user choose date through calendar date picker. Now I want to count the days between the two selected date and save the result in the database field totalDay(type integer), the following is my code: But when I click button and try to save it into database, I receive this error: The version of SQL Server in use does not support datatype 'time'.
how come when I retrieve my data from SQL my date field returns the date along with a time of 12:00:00 AM???? The Sql BD Type is Date and it is a date only in the SqlDB. I'm populating the date into a textbox.
I have an SQL statement that I am trying to use to connect a vb.net program to an access database.I am using to date/time pickers to provide the dates. I have searched around and the various changes I have made to the statement have not returned any results.For what its worth this query works ok within access:
SELECT * FROM tblcallLog WHERE startDate Between #" & dspstart.text & "# AND #" & dtpend.text & "#"
here is the entire click event, per @ajax81's request
enter code here
Private Sub btnDateUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDateUpdate.Click grpT2DateRange.Visible = True grpT2SingleStaff.Visible = True[code].....
where startDate & endDate are Date types. It tells me 'For' loop control variable cannot be of type 'Date' because the type does not support the required operators. Is there another way to loop through dates?
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?
