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.
In calendar module the days for the particular month of that year is displaying with the events of the day for that particular month,where i'm not getting the events constantly after the click of each month [code]

I need this for 2 different changes.ON one form i got a week calendar, the other a month calendar.Was hoping to add 2 buttons previous & next.To scroll back in time x days, or x days forward.And similar for the months, but instead of days months.Can anybody give me a exaple or a method how to get this to work?Figured it could be done with a loop, but not sure anymore.
The function for getting the difference in days between two days is giving me a wrong answer here.What could i be doing wrong??? DateDiff(DateInterval.Day, CDate("28/1/2011"), CDate("31/1/2011"))
on my design i have a listbox, datetimePicker and a button. how do i pick a date like for example 14 feb 2010 from the datetimePicker and click the button, then the listbox showing how many days from 1st jan 2010? should be 45days.

Have to find total days from two date controls after selecting dates in two controls it should print total days by calculating after immediate selection of second date control
I have an application that has 3 list boxes, one selects a workshop, the other a location. the third is to display selected costs.to do the calculation a loop is required. i have written the code but when i calculate the cost the final result to be displayed ends up as being the cost of the last work shop and location * 3,What is supposed to happen is the location is multiplied by the number of days(3 in this case) and added to the workshop cost.the loop is supposed to add all cost from the list box till all have been added.what is happening is the calculation goes to the last entry as stated the multiplys this total by number of days(dbl)?
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 :)
i'm going to do a calendar using vb.net. and the first step i'm doing is making a button and a message box showing system's date
my code is as below but it's not working. i thought date is one of the vb function to get system date?Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
i'm trying to make a calendar and now i'm trying to know whether if it's a leap year and how many days in the current month etc. but my codes doesn't seems to be working and i don't know where is the problem,
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???
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]
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?
im trying to make a program, basically its a time in time out, i can get the date from my database and its in three columns, the first one is the date work, next is the timein and the other one is the timeout. im trying to convert the timein and timeout into date which are string at first but i having a problem when the timeout is the next day of the actual datework for example one emplyee has datework of 1/1/2009 and he time in at 6:00PM i can convert it to date and it work be datework + " " +timein or 1/1/2009 18:00, but if i add one day to the datework so the time out is correct "1/2/2009 6:00" , it wont work T_T is there a problem in my codes? [code]
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.
