In my office we were using VB.net 2003 and MS SQL server 2000. Now we bought a license for vb.net 2008 and MS Sql Server 2005. I migrated our application to vb.net 2008..Now the code compiles without any problem, but when i run a report, it shows error. System. Data. Sql Client.SqlException : 'DateInterval.Day' is not recognized datediff option.It was working fine in 2003. [code]
View 6 RepliesI need to compare the date that is entered with today's date minus some number of work days.
I used dateinterval.day, but that is the actual day, not the work day. i don't see a "simple" way to get work days.
For example, my number is 3, so i want 3 work days (M-F) not 3 days.
I really like the coding speed that vb.net provides, but I don't like the possibility to forget to declare variable types, return types of functions, etc. and that is why in each class I use[code]..
Is there a way to define those two options on the project/solution level?
the combo box style 1 has both the drop down option but also a manual entry option. I need to know how to code it so that when you manually enter data, it takes that data and places it in a text message "The shipping charges for "data" is $15" displaying in a text box. Shouldn't be hard but have developed a mind block.

I'm trying to do a Datediff in VB.Net thats confusing me. Basically I'm trying to do the following. If DateDiff("D", Today(), rsData("Start")) > 0 Then This is working fine when comparing the value from SQL with todays date. I however need to convert this to check the current month and if it matches then return whatever I'm trying to show below.
[Code]...
If DateDiff(DateInterval.Day, moDoBooking.m_CurrentDay, moDoBooking.m_BaseDay) _
> DateDiff(DateInterval.Day, DateAdd(DateInterval.Day, _
Convert.ToDouble(moDoBooking.oBooking.oFacility.ADAYS), moDoBooking.m_BaseDay), _
moDoBooking.m_BaseDay) Then
This condition won't satisfy with these values:
moDobooking.m_CurrentDay = 2/3/2011
moDobooking.m_BaseDay = 22/02/2011
moDoBooking.oBooking.oFacility.ADAYS = 1
You might say this is dead-easy but honestly it's late here and my head is not working at all! Could AnyOne tell me why is that?
this code always return '0' i don't know why
Dim cur_month = DatePart(DateInterval.Month, Now).ToString()
Dim cur_date As String = "01/" + cur_month + "/" + (DatePart(DateInterval.Year, Now).ToString)

cnb_mnth is ComboBox for Month
txt_year is Text Box For Entering Year
I am trying to put together a booking system. I have managed to program rates, discounts etc., and am now onto calculating the nights for the stay. On my form I have two datetimepickers, and a button. The code I have entered is: (I am using Visual Basic 2008 Express)
CODE:
This works well when getting how many nights between two dates in the same month, but if I enter say 30th August to 2th September, I get a -28. Is there a way to get the number of nights booked between two different months?
I have five text boxes & one button there in my form. I have written this code to get user`s current age. But problem is that I have to get user`s age with months.
My code to get age :
Private Sub Command1_Click()
BDate = Text1.Text & "-" & Text2.Text & "-" & Text3.Text
CurDate = Now

I`m migrating access database to vb.net. I have employee database with a few DateTimePickers, textboxes, and comboboxes
In access I have formulas in textbox's control source like this, and it works:
txtDayCalculation=DateDiff("d",txtDateofHire, txtManualDate)txtYear=Int(txtDayCalculation/365)txtMonth=Int((txtDayCalculation-(txtYear*365))/30) txtDay=((txtDayCalculation-txtYear*365))-(txtMonth*30).
So, I have trying to do also in vb.net, but NOT successfull. Maybe my aproach to write a code is wrong. Anyway, I have write like this:
me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)
I want my console application to be able to do one function I have when you click one option on the windows context menu, and another function when you click another option.

which could be any day of the week. I've tried all sorts of things to programmatically set "FirstDayOfWeek.x", but it seems as though vb.NET wants it hard coded as FirstDayOfWeek.Monday or. Tuesday etc and you can't pass an integer like 1 or 2 so I could set it on the fly.
I am using the following code in my project. I want to find the number of days by given the last date and now.[code] for example, when BorrowDate is "01/Jul/2011" then the result is 7 days which it should be 10 to now.

View 1 Repliesi am using Visual Studio 2008 and VB.NET 2008 and SQL Server 2005 as the database. I just finished designing & writing codes for a customer information and , however after it has been connected to the database only one of the datetimepicker can be click, and the rest of the function including in the form are not working!it seem that the form stuck and NOT responding. i cant even close the form (X button), so i have to stop the process using compiler (visual studio 2008), however if i press the 'Delete' button before the 'Add' button, it will successfully delete the data.. but if i disconnected the form from the database, (disabled the form_load codes [put 'quote']) the both of datetimepicker will work and able to view the date interval (after pressing the 'Calculate Period' button) in addition how to make it appear automatically in screen without using the button? below are the code, I try to make some other form.. but it is still the same

I am using the folowing code to calculate the difference between two dates. intDaysInDev = DateDiff(DateInterval.Day, calManuDt.SelectedDate, calLaunchDt.SelectedDate) I've now been told that the calculation should not include weekends.
View 2 RepliesIs it possible to use DateDiff to find the difference between time?I have two time periods i.e. 05:00 and 05:10pm so i would like to run some code if the time is between the two specified periods. Ive searched around and i think DateDiff could do this but unsure?
View 2 RepliesI had some trouble specifying Monday as the first day of week in the DateDiff function.
The following syntax does not work: Dim myWeekNumber as Int32 = DateDiff("ww",date1,date2,2)
Compiler Error Message: BC30519: Overload resolution failed because no accessible 'DateDiff' can be called without a narrowing conversion
However, using the enumeration value (FirstDayOfWeek.Monday) instead of the value (2) does work. I wonder why.
I tested every example I found but it doens't work in vb 2010 express... Do I need to install anything moor to make it work?

[Code]...
1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.
2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]
I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.
I haven't touched a project in about 8 months. It's ongoing for work, but hasn't really been published fully so it gets worked on in my spare time. I went to recompile and the build failed. It had previously worked. I can't figure out why. Part seems to be due to AxOWC11 being recognized, but it shows up in the namespaces. I'm looking for the .dll that shows up as AxOWC11.dll, but I'm not seeing any. I do have one that shows up as AxInterop.OWC11.dll and I do have just a OWC11.dll in my list. I've posted some of the errors below.

when i start to type oledb.oledb..... intellisense would usually give me an option for oledbcommandbuilder. in the current program i am doing for coursework this option is not given. i can choose oledb.oledbcommand but i do not know how to use it (too advanced for A-levels, yes i'm british) if i actually type oledb.oledbcommandbuilder visual studio does'nt show an error in my error list. so what is going on? how can i get visual studio to recognise oledb.oledbcommandbuilder?
I would like to start a data base. Im using vb2005. I've started a new windows application. I have added a new data source to the project. Then I added a new TableAdapter in the dataSet.xsd part of the project. When I'm completeting the wizard, when I click on the QueryBuilder, when the add table window opens, the table already in the program ( that comes along with the TableAdapter ) isn't recognized. I've clicked on the refresh button but it still isn't recognized. (example: DataTable1 isn't recognized in the add table form in the query biulder of DataTable1TableAdapter)
