Value To Add Was Out Of Range (30 Days)

I'm getting the following error:
System.DateTime.AddDays (Doublevalue)+19

The line from which this error originates has the following code:
expires = Now.AddDays(30)
It occurs irregularly and irreproducibly. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative. It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Culture settings perhaps?

2005 - Subtract A Date From The (current Date Minus 7 Days) And Produce A Number Of Days?
I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)

Using Range In VB When End Of Range Varies?
I'm using vb in excel 2007 and need to work through a range or array, the size of which varies from time to time.

The examples of using range always demonstrate using literals eg "A1:A25"

How can I programatically determine the end of the range - ie up to where the cells value is blank

And then can I use a variable in the range statement - eg .[A1:Lastcell]

Run A Sub Every 30 Days ?
Lets say every 7 days you manually kick off a program that moves all old files to an archive zipped folder; and you run this same code every 7 days BUT at some point in time you need to go into that zipped folder and delete every file that is 100 days old........What would you suggest I add to the code I have now, that would automatically un-zip the file (I assume I do need to unzip it first) then do the delete of the files that are 100 days old or older? I am thinking I need to set a timmer or somthing to trigger in 100 days from now then reset it once it is triggered; am I on the right track here???

How To Use DirectCast Over Last Few Days
I learned how to use DirectCast over the last few days and it's really helped me. However, I have a similar issue, instead of textboxes I am looking at variables that are referenced in the class.To bring you all up to speed, I have four variables, a Boolean that dictates each of the 4 players I have playing my game. [code] I would assume it'd work similar to DirectCast but I am unsure. What I came up with caused errors: [code]

Calculate Days In Datagridview?
I have a datagrid in VB2008 currently set up with a column that has dates. I want to be able to calculate the number of calendar days of the Disp Date Column to today's date. Almost like the days360 formula in Excel. I cannot do it in Access as it is a linked data table and cannot do it in excel as the spreadsheet is being updated by the server throughout the day.

How To Disable An Application After 30 Days
I've got a really good idea for an application I want to develop and possibly try and sell online. There is one thing I have never done before, and that is disabling an application after 30 days. Let's say I want to let users try out the application for 30 days, and if they haven't bought it after that time, then the application disables itself.

Any possible ideas on how to implement something like this?

List All Days In A Given Year
I have VB 2010 Express Edition. I also have VB 6 Learning Edition. I am "dotnetizing" my pre-dot net demos. There is a VB3 demo that lists all the days in 1994 in a list box. I can select a specific date & click on a button & that date is displayed in a label.I've played around with the Date variable & I know that I can use the .now & .today & other methods. I know that I can add days to the current date. I want to be able to start on a specific date & year & list in a list box all of the dates from then until the end of the year. For example, from January 1st, 2010 thru December 31st, 2010.I know that I can choose a specific date, say, #1/1/2010# & use & get a time span, but that's not what I want to do.
