I need a function that would return true if the date provided was a payday or date of next few weeks paydays.Paydays are every 14 days on a Friday (not twice a month).I tried several attempts, but don't have a clue where to start, except that the function needs a reference date to calculate from.

I am using VB.NET. Is there a date function that calculates the date based on the number of months I have given?
for example, if i say July 2009 and looking for 10 months back, it should return Sept 2008.

I have an Sql server 2005 table called Emploeefl with 2 fields, EmployeeCode and Date of Birth. The data type for the date of birth is Datetime. I have a Date time picker on a vb.net 2005 form called dtDateOfbirth. When I click on the save button I get the error message "Conversion from string 'yyyy/MM/dd' is not valid. Below is the code
Dim newQE_Date As Date
newQE_Date = Format(Me.dtDateOfBirth.ToString, "yyyy/MM/dd")
'newQE_Date = String.Format("2008/09/10", "yyyy/MM/dd")

I got a quite a big sql statement and I get errors when dealing with dates and numeric values. All of this is in order to copy the data to a new table.so these variables I am trying to use for passing the data:
Dim orderdate As Date 'on my sql orderdate is datetime
Dim custntitle As integer 'on my sql is numeric(2,0)
Dim country As Integer ' on my sql is numeric(3,0)
for the date I get an out of range exception,and for these two integers (custNtitle, country) I get invalidCastExceptions when dealing with strings there's no problem but dates and numbers causes errors for me?

In every date field I have, I cannot update it if it is null. For instance, I have the following query and it will throw an error if the date fields are Null or zero lengths. Any ideas? I try and parse and get the following error: String was not recognized as a valid DateTime. if i don't, it throws a null error.[code]

I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.

I have a multiple-value-single-string as a parameter field in a report in Report Builder 3.0 (e.g. 20124, 20125). Now I want to split up this string, and show "Summer 2012" instead of "20124" and "Fall 2012" instead of "20125. I am using Visual Basic. Here is my two functions I have made in Report Builder 3.0 custom code. The error is in the second function in the "If Right(yearterm)..." line. It gives me a syntax error. If I write "String.Right" it gives me the error: "'Right' is not a member of 'String'". If i take out the whole "If statement" the report will run but "20124,20125" gives me this: ", 2012, 2012".

I have something that I want to do and what looks very simple, but I cannot get it to work. I want to build a function that gets as input a xdocument and some other strings. It should have a return that contains a filtered part of the xdocument in a way that I can use it as input for a new Linq function. This is what I mean:
Private Function fncGetFilteredDecendantsOfNode(ByVal xdocDoc As XDocument, _

1. I would like to know why a Return statement is needed in the function in the first set of code, but not in the second(even though it still works with the Return statement). The functions are called the same way, so what is the difference?2. Why in the second code, the variable FutureValue is allowed to have the same name as the function? But when, in the first set of code, I try to rename the variable "discountPercent1"(in the function) to the function name "SetDiscountPercent", VB 2008 Epress gives the error message "The name conflicts with an existing symbol with the same name"?

How can I do so?

I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
