I have an application that I need to determine if it is a new month, and if it is, it will automatically reset a 4 digit number to 0000.
Example: It is 11/17/2014, the 4 digit number is 1234.  On 12/1/2014 I need to the 4 digit number to be 0000.

I have been trying to write the code for it and I can not come up with a solution.  This is what I have come up with do far:
            If Now.AddDays((Now.Day - 1) * -1).AddMonths(1).AddDays(-1) >= DateTime.Now Then
                casenumber = "0000"

            End If

Open in new window


This does not work.  Any help on this would be greatly appreciated!!
Thanks in advance!

Could it be something as simple as:
If Now.ToString("MM") <> Now.AddDays(-1).ToString("MM") Then

Or even:
If Now.Month <> Now.AddDays(-1).Month Then

Ok so we are so close!!  The only problem I am going to have with this is what if they do not use it on the 1st and they use it on the 2nd?  I think the only way around this is storing the current month that it was assigned and then comparing the 2.

Testing Shauns example:
Module Module1
	Sub Main()
		Console.WriteLine(String.Format("{0} and {1} are in the same month: {2}", Now, Now.AddDays(-1), CompareMonths(Now, Now.AddDays(-1))))
		Console.WriteLine(String.Format("{0} and {1} are in the same month: {2}", New DateTime(2014, 11, 30), New DateTime(2014, 12, 1), CompareMonths(New DateTime(2014, 11, 30), New DateTime(2014, 12, 1))))
		Console.ReadLine()
	End Sub

	Private Function CompareMonths(ByVal date1 As DateTime, ByVal date2 As DateTime) As Boolean
		Return date1.Month = date2.Month
	End Function
End Module

Open in new window


Produces the following output:Capture.JPG
There is no need to store the date because you are using Now and Now.AddDays(-1).

His code works, the only issue is if a number is not generated on the 1st, but on the 3rd, the program will return false for a new month.

True.  So then in that case, your response is correct, you would want to save the date for the last case created somehow, so that when a new case is created, the program will validate the months and rollover if a new month is detected.

I appreciate both of you commenting!!  I ended up saving the last case number date and I am doing a DateDiff statement!  Shaun Kline comment works great, the only reason I did not use it was the change from December to January.  Thanks again to both of you!  You both put me in the right path to correctly fix the issue!!  This is the piece of code I ended up using:
DateDiff(DateInterval.Month, lastmonthassigned, DateTime.Now) >= 1
