Calculate The Number Of Months Between 2 Dates In Vb 2008?
Aug 5, 2009
I am attempting to calculate the number of months between 2 dates in vb 2008. Effectively subtracting a date in the past from the current date and then manipulating it to the number of months between the two.
I have done this in VB 6 previously, but can't seem to do it in vb2008.
Datediff calculates the no of months between two dates, Is there any function which lets you to calculate the same thing but also includes the current month. Datediff +1 would give the answer, but just wanted to know if theres any inbuilt method.
i need to get 2 dates and then add rows in a grid for that many months. e.g. the user gives 1st Jan 06 as first date and 30th Dec 2010 as second Date the rows should b
[Code]....
dont know why but am totally puzzled as to how to start with it....
How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date Dim D2 As Date Dim ts As New TimeSpan D1 = txtHStart_Date.Text D2 = txtHEnd_Date.Text ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.
How to calculate the difference in months between two dates in C#? Is there is equivalent of VB's DateDiff() method in C#. I need to find difference in months between two dates that are years apart. The documentation says that I can use TimeSpan like:
[Code]...
but this gives me data in Days. I don't want to divide this number by 30 because not every month is 30 days and since the two operand values are quite apart from each other, I am afraid dividing by 30 might give me a wrong value.
I am searching an MS Access database via an asp written in VBscript. I am looking for entries that are less than 45 days old. The query worked great until October rolled around. Then none of the new entries were being displayed. I discovered that any month that has 2 digits, such as October with 10 or even Jan-Sept if I enter a "0" in the month (ie. 09 vs just 9), will not display. The SQL statement is below (created in Dream Weaver):
<%Dim rs_blog__MMColParamrs_blog__MMColParam = "entrydate"%> <%Dim MinDateMinDate = DateAdd("d",-45,Date())%><%Dim rs_blogDim rs_blog_numRows Set rs_blog = Server.CreateObject("ADODB.Recordset")rs_blog.ActiveConnection = MM_intranet_STRINGrs_blog.Source = "SELECT id, employee, subject, blog, entrydate FROM blog WHERE entrydate >= '" + Replace(MinDate, "'", "''") + "' ORDER BY id DESC"
How do I get the data that has 2 digits in the month to display and only show the entries that are no more than 45 days old.
I've been given two dates that takes their values from two respective dtpickers.I've got to calculate the exact amount of days, months and years between them.[code]The problem is that this function gives me ALL the amount of respective days, months and years passed, but I need to split them up in the correct way. Ex, between 28/2/98 and 13/1/2007 the result should be 15 days, 10 months and 8 years. And above all, the result is that the function indicates one month more (or one year more) with only one day (or month) passed between the two dates!
I am trying to calculate the number of years for my calculate age event handler, however i am apparently missing a method or whatnot because im trying to calculate the age , can anyone suggest help on this. I need to subtract years to get my age but when i try the birthdate.Subtract (currentDate) method i get an error about not able to convert from LONG?
So below is what I have.
Private Sub btnCalculateAge_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculateAge.Click Dim currentDate As Date Dim BirthDate As Date Dim Age As Long
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'.
i have this function and i want it 2 calculate the difference between two dates and it is suposed to return the difference in days but it it just not working
I want to get the total years and months in a number eg. 25 should give me 2 years 1 month. and 11 should give me 0 years 11 months and maybe 12 should be 1 year 0 months,i have this code but it does work for me as i want it seems the loop i am using goes only once.
Dim Month As Double = 25 Dim LeftMonth As Double Dim Count As Integer = 0
So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with. Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click Function Factorial(ByVal txtFactorial As Decimal) As Decimal If txtFactorial <= 1 Then MessageBox.Show("Enter a number greater than 1") Else txtAnswer = Factorial(txtfactorial - 1) End If End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.
I try use datediff function to get month interval between 2 hijri dates but the function deals with the dates as Gregorian Dates so the result is not correct.
i'm making a program to calculate loan using dates, the customer borrows an item on a particular day and returns it on a given day else he would have to pay a certain amount of fine per day, which starts from the date of return if the user returns the item 1 day after the Date of Return, he pays a fine of 50pence if the user returns the item 3 days after the Date of Return, he pays a fine of 25pence per day if the user returns the item 10 days after the Date of Return, he pays a fine of 10pence per day and if the user returns the item 30 days after the Date of Return, he pays a fine of 5pence per day i did something like this, but it's not producing the required answer
Dim returned As Date Dim due As Double Dim fine As Double
I was working on a project afew months ago and I came back to it and been trying to figure out how come I cant get this to work right.I cam across this site and did not know if this is how to show it but if anyone like to help me out I added a pic. [code]
In VB2005 I am trying to calculate the number of business days between two dates. I must also account for U.S. holidays (New Year's Day, Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day/Friday after, Christmas Day). If a holiday falls on a Saturday, then the prior day (Friday) is assumed to be a holiday. Likewise, if the holiday falls on a Sunday then the following day (Monday) is assumed to be a holiday.
Before I build my own and after looking for quite a while (to no avai) does any one know of a function that will return the dates of a recurrence.
For instance:
- The recurrence might be the first Monday of each month.
- The second week of each month.
So what I want is to pass the recurrence information to the function and it will return in an array all the dates that are applicable.I've looked at some other topics here but none are as comprehensive as what I need.
I have following code (in VBA, excell) for calculating a date.I have variable for yeay, weeknumber and daynumber from week, now i wanna calculate the exact date. [code] But when i place this code in vb.net don't get the correct month.It displays correctly the year, day and daynumber but is displays the month as '00'. What do i have to change?
I have a program where I have to calculate straight-line depreciation (cost * 1/n) n being the number of years to depreciate, and Double-Declining depreciation (cost * 2/n) using user input for year of purchase, cost, and years of depreciation. The output needs to be put into 4 columns in a list box. Year, Value at beginning of year, Amount of depreciation during the year and Total depreciation to the end of the year.
The problem I am having is with my loop. It is not properly calculating. I'm sure I am doing something wrong that is simple, but I can't see it.
Here is my code; the problem areas are bold:
Public Class frmDepreciation
Dim Cost, Life, Year, Depreciation, BegValue, EndValue, Total, Counter As Double Dim fmtStr As String = "{0,-10}{1,10}{2,17}{3,5}{4,-15}" Dim fmtStr2 As String = "{0,-10}{1,10}{2,17}{3,15}"
