I have two dates, a creation date and an expiry date. I want to find out how many years and months (not days unless it is only days) between them.
I've got two dates:
Dim start_time = "12.5.2011"
Dim end_time = "15.11.2014"
I want it to say (3 Years, 6 Months) etc
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!

How do i calculate exact difference between to date including years, days, moths, weeks. Just like windows calculator does. ?
And represent like this 1 years, 1 months, 1 week, 1 day
I have made a new form on vb 2010. I need a small box which updates itself automatically to show the amount of years,months,days,hours,minutes and seconds from the 25/6/09. How would i do this in visual basic 2010?
View 3 RepliesI am new to VB 2010 and I am trying to right an application that takes in 2 years as inputs with in 0-3000 and displays all leap years in between and to check if the years are valid and output a message box if not.
I know that Every year that is evenly divisible by four is a leap year;
b.of those years, if it can be evenly divided by 100, it is NOT a leap year, unless
c.the year is evenly divisible by 400. Then it is a leap year.
But I cannot figure out how to put this into code. I have been looking up and trying tutorials all weekend.
With Vb.Net, How to get dates older than 3 months and less than 6 months ?
View 3 RepliesConsider the following 2 scenarios: Scenario 1). Today is May 1st 2012, and Scenario 2). Today is September 1st 2012.Now, consider that we write on our webpage the following about a comment someone has left: "This comment was written 3 months and 12 days ago". The amount of days in both these scenarios will ALWAYS be different even though the statement is exactly the same. In Scenario 1, "3 months and 12 days" would equal 102 days. However, in Scenario 2, "3 months and 12 days" would be 104 days!Now, to corner in on my point, lets use a different example and say that someone left a comment on our site on Jan 30th 2013, and today is March 10th 2013. Our real TimeSpan object needs to know this relative date, and can figure out the following:
That there is 10 days in March,That there is 1 day in Jan (counting from 30th to 31st).That the month Feb is one month regardless of how many days there are in it (even though it's 28 days).So, it would mean 10 days + 1 day + 1 month total, translating to This comment was posted 1 Month and 11 Days ago.Now, if you used the MS style TimeSpan object (or any TimeSpan object in any language), it would give you the number of days from 30th Jan to 10 March (39 days), and because the TimeSpan object doesn't store relative date (the base/initial date we subtracted to get the TimeSpan), if you asked it how many months and days it has been, it will assume there is 30 days in one month, or even worst, the average which is greater than 30 days, and return the rest in days, so to get to 39 days, it will tell you it's been 1 Month and 9 Days and you will get the This comment was posted 1 Month and 9 Days ago message. Remember, both these scenarios have the same start date and same current/end date, yes the Microsoft TimeSpan object, by not allowing us to tell it the month of Feb 2013 should be be considered, has given us a completely different TimeSpan, off why a whole 2 days. It has, in effect, lied to us.
The problem is, people will believe this, and who knows what perceptions they may have, how their perceptions of the past may change and the decisions & life choices they may make when trying to reconstruct events within the past inside their own minds, while never noticing or understanding the drawback and inherent failure of representing time that is so pervasive everywhere today. They will not understand that programming languages don't realize (or care) that last month had 31 days in it, as oppposed to 30, 29 or 28 - or visa versa, and that this adds up when you increase the TimeSpan.
This is the problem at the heart of this post. I understand that most people will not care about this difference (but be sure that some of us do, and cannot have this on our backs), and if this doesn't bother you, thats ok. I wish it didn't bother me, I would have saved myself some time, stress and disappointment. If this is not a bother, you can use the function for the efficient textual display of relative time (customizable to 1 to 6 nodes from seconds to years), instead of using it for the usually negligible accuracy it provides.
To my disappointment I noticed that there is no real timespan object, if you get a timespan, and do a .years or .months you'll get nothing, you'll only get .days and lower because a timeSpan object doesn't carry anything to tell it which month or year the timeSpan was created on. Therefore it'll never really know how many months it's been since days in each month vary over a year and even further over a leap year.I figured there'd be a ...
timeSpan.GetActualNumberOf[Months/Days/Hours/etc] (base date must be provided of course)
... type method on this datatype, but there wasn't.All you'd really have to do is create another property on the timeSpan object to give it a base date on which the difference was calculated, then the above lovely string would be calculable pretty easily, and a .year & .month would exist!
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

I am trying to calculate the exact amount of time in Years, Months and Days between 2 date values. I'm getting stuck on the day calculation. I've returned the # of months and it's value is 8.77. The .77 needs to be rounded to 8 which should give me the days. I'm not exactly sure what MATH function to use to do this.

Rounding the 9999.96 with 2 decimals of presition i got 10.000 $ but that's what i don't want since 0.04 is a loss.Im using SQL Compact 4.0 as database, the price_month table is decimal(18,2)

Dim pricemonth as Decimal = Math.round((price/12),2) ' 833.33

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 have the following VB.NET Code:
Dim Date1 As New DateTime(2010,5,6)
Dim Date2 As New DateTime(2009,10,12)

What I am trying to do is find out how many months are between the 2 dates.
I have two date values.
Example:
Dim d1 As DateTime = New DateTime(2010, 6,6)
Dim d2 As DateTime = New DateTime(2011, 2,2)
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.

View 6 RepliesAbout 3 years ago i came across a vb project for a photo album, it was on online tutorial and I followed it and after some custom tweaking I found it was quite usefull.

so if i say want to cruise 29 miles at 12 knts it gives me an awnser of 2 hours 24.6 mins instead of 2 hours 25. Although i do realise that 2 hrs 24.6 is technicaly right i was wondering if anyone here could help me with getting it into the correct format?
im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]
