List All Days In A Given Year

Feb 21, 2011

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 date.now & get a time span, but that's not what I want to do.

2005 - Subtract A Date From The (current Date Minus 7 Days) And Produce A Number Of Days?

Sep 28, 2010

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 :)

Run A Sub Every 30 Days ?

Jan 25, 2010

Lets say every 7 days you manually kick off a VB.net 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

May 8, 2011

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]

Value To Add Was Out Of Range (30 Days)

Aug 16, 2010

I'm getting the following error:
[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
System.DateTime.Add(Double value, Int32 scale) +7657639
System.DateTime.AddDays (Double value) +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?
