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

Consider 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'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 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:
