I have an installment payment program which have Hijri date (Saudi Arabia) and I already have the code for it's converter inside the forms (using datetimepicker for the Gregorian & maskedtextbox for the Hijri). I'd like to know how can I convert or produce the corresponding equivalent Hijri dates of a series of Gregorian dates generated in my table? I am using SQL query for this. This triggers when I click my Save button for the computation of the premium terms of the customer having an installment payment plan for an item boughtIs there an SQL query to convert Gregorian dates saved into Hijri dates to an Access table?By the way, I am not using any SQL server or Oracle,
I have a table in sql where the date format is stored in Hijri. Now I am working on a vb.net application where I have to let the user update that dateField. So is it possible that if I place a datepicker(which is in Gregorian) and user selects the date and its converts into Hijri date before updating. I mean when the user selects the date and clicks the save button the date should be updated in hijri format in the sql .
For now , the user is entering the date manually on a tms AdvEdit.
Is there any code available to accomplish this task.
I try use datediff function to get month interval between 2 hijri dates but the function deals with the dates as Gregorian Dates so the result is not correct.
I have made a simple program in VB.Net.In this program I made two DataTimePicker with the names of
1. DtpFrom 2. DtpTo
I want to get the dates from tblStudents between the dates given in the dtpFrom and dtpTo.The Date Format for these two DateTimePicker and in tblStudents is "M/d/yyyy".When I run this query.
"Select AdDate from tblStudents where AdDate >= '" & Format(dtpFrom.value,"M/d/yyyy") & "' and AdDate <= '" & dtpTo & it gives me some times correct results but some times it missed some of the dates. I want to get the precised dates, without missing any date. So is there any Mechanism to solve this Problem.
I'm having some trouble. I have an sql statement to update some rows to an Access DB I enter a date like 01/08/2009 (1st Aug 2009) and it saves to my DB as 08/01/2009 (08th Aug 2009 but still 01 Aug if it were mm/dd/yyyy format)
I have a database application connected to a sql express datafile, i am using a datagridview and have clicked on the arrow and added a query. the query is simply sort / ascending on my date field which is a text field with auto generated when the field is focused so i know the dates are entered correctly but when i use the query they are not in their correct order. [Code]
When I'm trying to run this program Sql QUERY doesn't work properly , but the month and day are okay but it comes to year it doesn't work...
Dim strSql As String = "SELECT * FROM tblAudit WHERE Date_Time BETWEEN '" & Format(dtpFROM_F.Value, "MM/dd/yyyy") & "' AND '" & Format(dtpTO_F.Value, "MM/dd/yyyy") & "'" classLibrary = New ConLib classLibrary.openConnection(strConnection) lblconstat.Text = DatabaseStatus If Not classLibrary.isconnectionopen() Then Exit Sub End If classLibrary.initializeCommand(strSql)
I am building an application where a button click runs a sql query and shows a user the next available date that they can process from. The problem was that it needed to be the following Sunday and not the following day.
That code looked like this:
Public Class Form1 Dim ReturnValue As Object = Nothing Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Trying to work out if there's a nice way of doing this, preferably in Linq rather than loops, which is what I've done for now.
I want the number of days my Product is active between two dates.
Product has many ProductHistories, ProductHistory has values for DateActive and DateInactive. DateInactive can be null, and often will be, to show that this history is ongoing. Histories won't overlap.
I want to sum the maximum of my startDate or the ProductHistory's DateActive, and subtract that total from the sum of the minimum of endDate or ProductHistory's DateInactive (endDate by default if DateInactive has no value).
Worked example:
Get active number of active days between 2011-01-01 (1st Jan) and 2011-02-01 (1st Feb)
Histories:
Active 2010-12-25 : Inactive 2011-01-05 Active 2011-01-15 : Inactive 2011-01-20 Active 2011-01-25 : Inactive null

Code:"select payrolldate from payroll where(payrolldate <= getdate())and payrollran <> 'yes'")but when I add that query it just returns a value of 1/1/000 as the date.
I need to add a gridview to my page where the sqldatasource is based on a query that returns records that fall between Sunday and Saturday of the current week. (Each record has one date field) The records are for payroll purposes and the payroll week runs from Sunday to Saturday. I need to find all records that fall in the current pay week.
I am new to LINQ, how to convert the following SQL query to LINQ? SELECT Date,ShiftName,Max(Score) AS Score, 1 AS IsPreferred FROM Temp_Nurse_Fill_RequestNumbers group by ShiftName,date
SELECT EqID, MakeID, Model, Description, (SELECT MAX(EvDateEnd) AS MaxOfDateEnd FROM tblEvent WHERE (EqID = tblEquip.EqID) AND (Event = 'REG')) AS RegExpire,
[code]....
For example, I want to get the Max EvDateEnd from the Events table for each record in tblEquip, but not all records in tblEquip have the "REG" event, while others have multiple REG events.Some events (like EAE) I leave the tblEvent.EvDateEnd field blank to show the event is open and ongoing, such as issuing a vehicle to an employee(entity). when the vehicle is returned I enter the date in EvDateEnd essentially closing the event.
I have this query that returns the number of rows which is :
SELECT COUNT(*) AS MemberTotal FROM Members
i'm trying to write a readonly property called count to return that value in string its suppose to display the result of my query in a tool strip status label, I have this in my code
Public ReadOnly Property count() As String Get Return memberAdapter.GetMemberCount() End Get End Property
but it gives me an error saying I can't convert dataset to string something like that and I don't have any idea on how to convert it I tried the Cstr but that didn't work?
I have the following routine (that works) but which is messy to update owing to the hand-typed strings it uses:

I've created a small WPF app in VB9 to catalog our sizable DVD collection. This exercise has been more about learn programming than the need to have a movie database app, but I digress.The SQL database I created has a field for "Genre" that does not have an entry for all the movies in our collection. As such, when I run the method that filters the movie listing by "Genre" the compiler throws the "StrongTypingException was unhandled" error stating "The value for column 'Genre' in table 'Movies' is DBNull.".
I now understand where the DBNull problem comes from and have been searching for several hours to find a VB solution that converts the DBNull fields to strings on the fly during the LINQ query. I've found many solutions people have tried but, since I'm quite new to all this, none of them have worked for me. Pasted below is the method that throws the exception.
Is there a way to convert a string into a linq query? Searching for those words brings up tons of stuff unrelated to what I'm trying to do..For instance, this works, of course...
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apple" Select item)
But somehow I want to do this:
Dim strQuery = "From item in htMyTable.values where item(0) = " & CHR(34) & "Apples" & CHR(34) & " Select item" Dim lstMyQuery = (Somehow run/convert strQuery as a query)
The reason is strQuery will be different each time depending on what the user has selected earlier in the program.R if lstMyQuery is already a collection, is there a way to add to it?
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apples" Select item)
(this obviously doesn't work, but it's basically what I want to do...)
lstMyQuery.Add(From item in htMyTable.values where item(0) = "Oranges" Select item)
I'm using two datetimepicker controls to set the start and end dates for a range of dates I'm searching for.I want to make sure that the start date selected is not greater than the end date. This code works, but it runs the messagebox prompt twice for some reason. I've tried to ignore it from doing this, but it's not working. Can someone tell me what's wrong?

I used the query designer to create a qry from a datagrid view in vb2010 express, the idea was to work out which diver logged the most minutes in the water. here is a copy of the sql syntax:
SELECT MemberID, Name, SUM(DiveTime1) AS D1, SUM(DiveTime2) AS D2, SUM(DiveTime1 + DiveTime2) AS s1 FROM Triplog GROUP BY MemberID, Name ORDER BY s1 DESC
I have this situation where I have a SqlDatasource control and the select query is like:
SELECT col1, col2 FROM table1 WHERE colDate = @date
The source of @date is a label with the text: 2009-05-29 12:06:00 I get the following error when I run the query:
Conversion failed when converting date and/or time from character string
I tried using convert(datetime, @date), as well as different date/time formatting of the label itself. Everytime I get the error.
However, when I run the query in the management studio like:
SELECT col1, col2 FROM table1 WHERE colDate = '2009-05-29 12:06:00'
I found out that the @date is parsed as 05-29-2009 01:30:00 TT I don't know where the TT is coming from? And I'm sure SQL Server wouldn't be able to handle it?
