Problems with Date objects
I'm writing a program that's interacting with a database that has two tables. The table relevant to my question is my customer table, which has a Date/Time field that expresses the current customers account expiration date.
I'm having trouble comparing a customer's expiration date to another date object to verify if their account expired. This code checks if a Dvd is checked out, if it isn't, ask the user's account number. Next I check (where error keeps occuring) if the expiration date is prior to todays date, thus making it valid, but it doesn't work that way. In which ways can you go about comparing two dates? Maybe I missed a certain method pertaining to comparing dates, I saw a compareTo, nothing like an isLessThen or similar. Any help would be greatly appreciated, thanks a lot. Also, when I copied my code over it automatically put returns so it's sort of hard to read, sorry for that. :
If dbSetAdapter.Tables("Dvds").Rows(index).Item("CheckedOutBy") = "XXXXXXX" Or 0 Then |
Re: Problems with Date objects
You can deal with dates in a number of different ways. If you think hard enough and work hard enough, you can even deal with them correctly.
My approach is to convert evey date that is to be subjected to manipulation to a form that represents a a numerical value expressing time elapsed since some benchmark time in the past. You, too, can do this. It doesn't much matter whether you read the material pertaing to VB, or to PHP, or to C, or to a non-language entity such as an operating system. Read, understand, adapt, and write. |
Re: Problems with Date objects
Enclose cusSet.Tables("Customer").Rows(accountIndex).Item("ExpirationDate") in a CDate, and see if that solves the issue. In some cases, it may not implicitly convert an object in an equation when you're working with Data, and so it may just stay as an object.
It should be like: :
If CDate(cusSet.Tables("Customer").Rows(accountIndex).Item("ExpirationDate")) < Date.Today ThenTry that, and see if it works. Could be overly simple, and perhaps you've tried it before, but it might work. |
