Date Function : IsGoodFriday


When I worked for an insurance company, Good Friday was a work day but not a business day. Only certain batch processes needed to run.

Function bIsGoodFriday(dCompare_date as date) as Boolean

   Dim iCurrent_Year             as Integer

   dGoodFriday = DateAdd("d", -2, dEasterSunday)

   bIsGoodFriday = dGoodFriday = dCompare_date

End Function

    variable declaration will compile by VB like that
    dim a as variant ,b as variant , c as variant, d as variant
    dim e as integer
    on other way;
    dim a, b, c, d
    dim e as integer
    because variant is default datatype. (and stored memory 20 bytes and upper depend on variable data long) and if u use variant datatype you could not take any error messages. The Variant covers all data type.

    if u will use that a, b , c , d and e as integer, u have to write

    dim a as integer
    dim b as integer
    dim c as integer
    dim d as integer
    dim e as integer

    and other syntax ;
    dim a as integer, b as integer, c as integer, d as integer
    dim e as integer

    huh is it?
    you can test two ways declaration, breaking one point and use on debug window

    print typename(a)
    first wrong declaration input "variant" and first assigment on a as integer "integer" but not like integer has take memory 20 bytes for variant variable type and 2 bytes for integer.

  • The exponential growth of data, along with virtualization, is bringing a disruptive level of complexity to your IT infrastructure. Having multiple point solutions for data protection is not the answer, as it adds to the chaos and impedes on your ability to deliver consistent SLAs. Read this white paper to learn how a more holistic view of the infrastructure can help you to unify the data protection schemas by properly evaluating your business needs in order to gain a thorough understanding of the applications …

  • With JRebel, developers get to see their code changes immediately, fine-tune their code with incremental changes, debug, explore and deploy their code with ease (both locally and remotely), and ultimately spend more time coding instead of waiting for the dreaded application redeploy to finish. Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.
