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 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"))
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 :)
We have a system were a user chooses a combination of days from a calander. We then insert a values in the databse based on the following [code]So if they picked Monday and Friday we would insert 34, or if they picked Monday,Tuesday and Thursday we would insert 22.Now my question is how do I reverse this easily in code, to find out what days they have picked. So I get fed 22 from the database how do I figure out what combination of days make up that value. The only thing I can think of is creating the mother of all case statements but I know there must be a better way.
I got 2 dtpDateTimePicker1 and dtpDateTimePicker2 with txtStart.Text and txtend.text there showing the ("en-US") "MM . dd. yyyy" and i get the date difference , works fine but i want to use the German ("de-DE") When i chance the format to dtpDateTimePicker2.CustomFormat = "dd / MM / yyyy". its not calculating the days right
Here's the code i am using
Private Sub Vaction_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' Creates a CultureInfo for German in Germany.
Dim ci As New CultureInfo("de-DE") Dim dt As DateTime = DateTime.Now
Ok, say I have an application that has a setting called start. and when a button is pressed on the form, it puts a day in there or something, then the button becomes disabled. then when the application is opened 2 days (48 hours) later, the button becomes enabled for use again. How could I do this?
I need want to create a array for the days of the week.
Dim DayOfWeek As Integer = Date.Today.DayOfWeek might give me 1 meaning monday, and i want it to looking in the array for the value 1 and find the one that matches.
I have this requirement in my app. I need to define a week, so for example, I have a GameWeek table. it has weekid(PK),description column. Then I have a GameWeekDay table which has an ID,WeekID (fk to above table), GameDate, isValid (bit field). So once I create a week, I need to select valid days for that week. so I will have a checkbox column for a user to click a day. and on saving, I will save the Date and the checkbox value to my GameWeekDay table. What I need is a clever UI design.
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)?
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?
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.
The program operates a board and activates relays when the buttons are pressed, the code works fine and i have published it to use on a PC however, after about 2 days the port times out and it stops operating the port, am i missing any code such as close port anywhere.
