DropdownList - Retrieve Previous 24 Months
Apr 22, 2011
I am populating a dropdownlist with the prior months/year for the end user to select. I am able to pull everything within the current year but I am looking to extend this to a 24 month period.
So far I have
Dim dateNow As Date = DateTime.Now
Dim dateMonth As Integer = Month(dateNow)
Dim dateYear As Integer = Year(dateNow)
For i As Integer = dateMonth To 1 Step -1
ddlTime.Items.Add(DataCalls.Calls.Production.GetMonthName(i,dateYear))
[Code] .....
As you can see, this will only give me the current month down to Jan of this year. I want to go beyond that.

If I modify a program of mine in some parts, adding also some settings in My.Settings and changing version, then I have to compile and create a new installer with the dear old InnoSetup.
Then I install the program, I go to see the settings ... and I see that them are the default settings stored in the MyProgram.exe.config file shipped with the new installer.
But is absolutely easy that a user would have changed the settings in a previous version (if existing) of the program.
So now the question is: during the new installation is there some clean and tested method to retrieve and update the settings set by users in any previous version of a program?

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

First of all i'd like to say thankyou for my last couple of threads as i've found useful ways to make my application great.
Now this is more of an extra credit function more than a necessity.
So for example if the date I currently have is 30/01/2010 how could I make that 30/02/2010? I want the program to add it on for each calandar month, if it's easier for every 4 weeks then that's fine. So is there a way to add to the "Now" function?

Datediff(Months, "13/07/2010", "13/03/2011")
The result of that is 8. Since 8 is the result i want to convert that into months witch supposed to be:

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.

When you open a MonthCalendar control at runtime, and click on the top Month designator, it takes you to a list of all 12 months in order to jump back or forward to a desired month quickly.
My question is, can I restrict the user to only viewing this 12-month calendar at start-up, so that I can just read the Month the user wants to say run a report from.
I realize I could use just a DropDown, or list box with the 12 month names in it, but since the control has this ability to view by month, I figured I would ask.
It would also allow me to reuse a control that I also use to pick a specific date, keeping my code a bit more compact on filesize, and save the control space for a new Combobox or something.

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.

im trying to learn how to made stuff with currency.For example:I divide 10.000$ by 12 Months, rounding with 2 decimals i have 833,33 $.If i multiply 833,33 $ * 12 i got 9999,96 $, so there is 0.04 of possible loss.
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)
Here is my code:
Dim price as Decimal = 10000
Dim pricemonth as Decimal = Math.round((price/12),2) ' 833.33
Console.Writeline(pricemonth*12) ' 9999.96
Console.Writeline(Math.round((pricemonth*12),2)) ' 10000

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!
