I need to find the date of Monday this week programmatically.For example, for this week Monday was on the 9th, so the date I need is: 09/11/2009.And when we roll over to next week it needs to calculate: 16/11/2009..I have tried doing this myself but I can't see how to do the arithmetic.
I have a two buttons: Previous Week & Next Week When i run the app the LabelDate needs to shows up "May 31, 2010 - June 6, 2010" When i click a previous week button i want to set LabelDate's text to "May 24, 2010 - May 30, 2010" If i click Next Week button i want it shows up "June 7, 2010 - June 13, 2010" Means it should always display previous/next week starting from Monday and ending with Sunday.
I have five text boxes & one button there in my form. I have written this code to get user`s current age. But problem is that I have to get user`s age with months.
My code to get age :
Private Sub Command1_Click() BDate = Text1.Text & "-" & Text2.Text & "-" & Text3.Text CurDate = Now
I am using the following code in my project. I want to find the number of days by given the last date and now.[code] for example, when BorrowDate is "01/Jul/2011" then the result is 7 days which it should be 10 to now.
One of the problems with datediff function is that even if the two dates are 31-12-2011 and 01-01-2012,it will show the difference as 1 year.How to overcome this problem?
DateDiff for the interval Day gives expected results for days past until present, but if the first date is further in time than the second date, it gives the difference +1. Is there something I'm doing wrong? For example, if I put in today for both, the difference is 0. If I put in yesterday and today, I get 1. This is all expected, but if I put in tomorrow and today, I get 0, and two days from now and today give -1. Why is the function giving altered results if the date is negative?
Here is the specific code.
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged TextBox1.Text = DateDiff(DateInterval.Day, DateTimePicker1.Value, Date.Now) End Sub
I have a project, a database with employee information (name, town, birthday, HireDate, etc). I have add custom TextBox (on fly), and on that TextBox a
TexBox1.text = DateDiff("d", HireDateDateTimePicker.value, Now) . Which is calculating how many days worker is working in company from HireDate,and Now.I have put code on event TextBox1_TextChanged. But, this means that I need to move cursor in TextBox1 to apply changes. I have also try with MouseMove. It works, but if I would have a huge database, then application will all the time reading script on MouseMove, and by that will slow down entire program.
I am currently writing a scalar valued function and I'm having a few issue with the returned result. I have narrowed the problem down to a calculation that convert the difference between two dates as a percentage/decimal. No matter what I try the return value is always a whole number set @earnedpremium = (@premium * @pretripearnings) + ((@premium - (@premium * @pretripearnings)) * cast((datediff(day, @outdate, @experiencedate) / datediff(day, @outdate, @returndate))as decimal(5,2))) The cast section needs to return the percentage, I know the rest is working fine through some elimination and testing.
I need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates. There is an ISO spec to do this but seems awfully complicated! Im hoping someone knows of a way to do it in C# or Visual Basic (its actually for Visual Basic 6 but I will try port it across)
I need to show a report, which will show weekly report for training session.. from Monday to Saturday some time Sunday with the number of participants per day.i want sql query to complete this task.eg.
code days mon tues Wed thurs fri sat sun 10001 3 22 22 22 0 0 0 0 10002 5 10 10 10 10 10 0 0 and so on....
Here no. of participants are same for all days of that training session.
Updated Query .....................my query as per @competent_tech suggestion ......................... CREATE VIEW SessionDOW AS
[code].....
here week start from 12th dec and end to 18th dec but training session start from 5th dec and ends at 14th dec but still next few days(15,16,17,18) showing participants value.
I have a DateTime struct I use, and sombody commented out the part where it was created (but not declared) When I was using it, myDate.DayOfWeek == DayOfWeek.Monday returned true.
If the part where it is created is commented out, how can it tell me it's monday, instead of throwing some exception?
l = SQLDataSet4.Tables(0).Rows(j).ItemArray(1).ToString
Dim SQLStatement6 As String = "UPDATE `scheduler`.`teacher_report` SET `'" & l & "'` = 'Not Available' where `teacher's name` = '" & SQLDataSet5.Tables(0).Rows(k).ItemArray(1).ToString & "' and time = '" & SQLDataSet5.Tables(0).Rows(k).ItemArray(2).ToString & "' "
unknown column monday in the field list which refers to l but if i type on monday it is okay..
I'm trying to do a Datediff in VB.Net thats confusing me. Basically I'm trying to do the following. If DateDiff("D", Today(), rsData("Start")) > 0 Then This is working fine when comparing the value from SQL with todays date. I however need to convert this to check the current month and if it matches then return whatever I'm trying to show below.
I am trying to put together a booking system. I have managed to program rates, discounts etc., and am now onto calculating the nights for the stay. On my form I have two datetimepickers, and a button. The code I have entered is: (I am using Visual Basic 2008 Express)
CODE:
This works well when getting how many nights between two dates in the same month, but if I enter say 30th August to 2th September, I get a -28. Is there a way to get the number of nights booked between two different months?
In my office we were using VB.net 2003 and MS SQL server 2000. Now we bought a license for vb.net 2008 and MS Sql Server 2005. I migrated our application to vb.net 2008..Now the code compiles without any problem, but when i run a report, it shows error. System. Data. Sql Client.SqlException : 'DateInterval.Day' is not recognized datediff option.It was working fine in 2003. [code]
I am writing some code that is trying to determine how far through a season we are in a game we play.

The code below, sort of works:

which could be any day of the week. I've tried all sorts of things to programmatically set "FirstDayOfWeek.x", but it seems as though vb.NET wants it hard coded as FirstDayOfWeek.Monday or. Tuesday etc and you can't pass an integer like 1 or 2 so I could set it on the fly.
i am using Visual Studio 2008 and VB.NET 2008 and SQL Server 2005 as the database. I just finished designing & writing codes for a customer information and , however after it has been connected to the database only one of the datetimepicker can be click, and the rest of the function including in the form are not working!it seem that the form stuck and NOT responding. i cant even close the form (X button), so i have to stop the process using compiler (visual studio 2008), however if i press the 'Delete' button before the 'Add' button, it will successfully delete the data.. but if i disconnected the form from the database, (disabled the form_load codes [put 'quote']) the both of datetimepicker will work and able to view the date interval (after pressing the 'Calculate Period' button) in addition how to make it appear automatically in screen without using the button? below are the code, I try to make some other form.. but it is still the same
Code: Imports System.Data.SqlClient Imports System Imports System.Data[code].....
I am using the folowing code to calculate the difference between two dates. intDaysInDev = DateDiff(DateInterval.Day, calManuDt.SelectedDate, calLaunchDt.SelectedDate) I've now been told that the calculation should not include weekends.
