I'm pulling into a variable a datetime value. Now, I want to post this value back to my database, but I need it to be only the year digits. How do I get VB.NET to trim the month, day, and time off and just return the four character year (e.g. 2011)?
View 3 RepliesI recently moved a webservice VB.net project from VS 2005 to VS 2008 and now a conversion I use to create a unique receipt number is no longer working.
The Format() function which is supposedly a Visual basic function gives the error:
'Format' is a type and cannot be used as an expression.
The Year() Function which is also a VB function gives the error:
Name 'Year' is not declared.
The Datetime() Function which is also a VB function gives the error:
'DateTime' is a type and cannot be used as an expression.
The actual code statement remains unchanged between the two web services but VS2005 compiles and VS2008 does not.
Dim julda As Long = CLng(Format(Year(oneRowDon.Item(8)), "0000") _
+ Format(DateTime("d", CDate("01/01/" _
+ Format(Year(oneRowDon.Item(8)), "0000")), oneRowDon.Item(8)) _
+ 1, "000"))
when i get system date and add some day or month or year then i want next date as per requirement.

I need to check my field in format ddMMyyyy(ex 12/03/1990) whether in interval of two dates that user picks from two date picker controls. Two date pickers are in custom format dd/MM. It does not matter for me if its between particular years. I need just to know if given Birthday belongs to interval taken from screen. Each datepicker gives values dd/mm/yyyy. I do not know how to check it. For example:Given date 12/03/1990 . User select two values from screen: From 01/01/1950 Upto 30/04/1949(or 1990, or 2000)
Result should be True.Because 12 march is between 01 Januar and 30 April.

I'm trying to split a date column into multiple columns by year. If I could achieve a roll-up subtotal at the end that would be awesome.
I'm thinking the best way to do it, is using a .NET datalist control, but I'm open to suggestions.
