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
[Code].....
If DateDiff(DateInterval.Day, moDoBooking.m_CurrentDay, moDoBooking.m_BaseDay) _
> DateDiff(DateInterval.Day, DateAdd(DateInterval.Day, _
Convert.ToDouble(moDoBooking.oBooking.oFacility.ADAYS), moDoBooking.m_BaseDay), _
moDoBooking.m_BaseDay) Then
This condition won't satisfy with these values:
moDobooking.m_CurrentDay = 2/3/2011
moDobooking.m_BaseDay = 22/02/2011
moDoBooking.oBooking.oFacility.ADAYS = 1
You might say this is dead-easy but honestly it's late here and my head is not working at all! Could AnyOne tell me why is that?
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.
View 1 RepliesI had some trouble specifying Monday as the first day of week in the DateDiff function.
The following syntax does not work: Dim myWeekNumber as Int32 = DateDiff("ww",date1,date2,2)
Compiler Error Message: BC30519: Overload resolution failed because no accessible 'DateDiff' can be called without a narrowing conversion
However, using the enumeration value (FirstDayOfWeek.Monday) instead of the value (2) does work. I wonder why.
I tested every example I found but it doens't work in vb 2010 express... Do I need to install anything moor to make it work?
View 2 RepliesOne 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?
View 17 RepliesDateDiff 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 changed the date of datetimepicker format to yyyy-mm-dd in custom format...but it displays 2009-00-22...the month part is not showing the month of the exact month..how to change the format of the date?
View 3 RepliesI'm not at all familiar with VB but do occasionally use C#. Really, i'm a BI guy who uses T-SQL on a daily basis in SSRS, which is why I have a question.I have a scenario where i've built a series of charts in SSRS 2008. Unfortunately, the functions available to me in SSRS are not enough for what I need my charts to do so I have decided to build my own function in embedded code. In SSRS, only VB.NET can be used when writing embedded functions.
I have opened Visual Studio 2008 Pro, created a solution and started building my function in Visual Basic 2008. So far, all is going well - i'm accepting a parameter which contains a string "date" of JAN-10, doing a substring operation on it to parse out the month and year, concatenating "20" to the two-digit year portion to get the full year. This part all works just fine.
For the three-letter month portion, i'm trying to use the MONTH() function to return it as an integer but unfortunatley it does not seem to be availble to me in Intellisense, which of course probably means i'm not accessing the class correctly. The odd thing is that the MonthName() function is available, but of course I can't use this with string values like "JAN" or "FEB" because it only accepts an integer. I'm familiar with the fact that in C# I can add a USING statement to the top of my class file to access a namespace, but i'm not sure how it works in Visual Basic 2008 because i'm honestly never used it before.
So my question - and this is probably a very basic question here - how do I access the Month() function? Which class or namespace (or both) do I have to reference in order to use it?Below is a screenshot of what I have so far, you can see from the Intellisense menu that the Month() function is not available:

I need a 2 functions:

Currently i have a ReturnSystemDate in a module, so that whenever i need the current date and time i call this method, however my data is saving as in 1 format and displaying in another. I have my variables set up as dateTime to store the current date and time, when calling System.dateTime.now.toString() i get 11/08/2010 Time, however when casting to Date as in CDATE() i get 08/11/2010 time. How can i stop this?
View 13 RepliesI want my game to tick over month by month at a set interval. I would use the timer control to get the interval. But how can I pause it? Say if one "month" is 5 minutes in my game and user hits pause. I would disable the timer but then when they unpause the game the timer would start from 0 again. This would make a "month" 9 minutes if a user paused the game in the 4th minute.

I`m migrating access database to vb.net. I have employee database with a few DateTimePickers, textboxes, and comboboxes
In access I have formulas in textbox's control source like this, and it works:

me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)

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.
