    Help With Date Calculation Function

    Hi Everyone,

    I have been working on a function to calculate the number of months between two dates. I am now stuck as I am new to functions as well as VB2008.

    There is one value I want to input: dueDate
    There is one value I want to output at the end: debtMonths

    Can anyone see if I am going along the right lines and also how I can finish this off by using the function in a Macro.

    If I need to provide any more info please let me know.

    Thanks

    I assume you are not familiar with teh DateDiff VBA function (or the DATEDIF worksheet function for that matter)?

    Thanks Roy,

    I have amended the function slightly as VB2008 came up with some errors (obviously I am not using Excel for this).

    My final MsgBox gives the difference between EndDate and BeginDate like I need.

    Can anyone tell me now how I can use this function within my macro below:

    You aren't using VBA?

    The messageboxes need deleting, I just put them in to check that I was getting the correct numbers.

    I am using Microsoft Visual Basic 2008 Express Edition.

    Now that I have this function I want to be able to use it in a Macro/Class/???. I am not sure what it'll be called?

    It is a Windows Form I am producing. I am trying to assign the result from

    to an object of CreditCard1Months. But I am stuck.
