Jun 9, 2010I am developing a C# VS 2008 / SQL Server 2005 Express website application. I have tried some of the fixes for this problem but my call stack differs from others. And these fixes did not fix my problem. What steps can I take to troubleshoot this?

How To Store DateTime Object With CultureInfo
Mar 2, 2011Does the DateTime object stores the CultureInfo with it, or you need to use the Formatter to format the DateTime according to current culture ?
I have a class property that retuns a DateTime. Within that property I am setting the DateTime object with current culture information using CultureInfo object. Below is the code for class property I am using:
public DateTime PrintedQuoteDate {
get{
DateTime printQuoteDate = DateTime.Today;
// cInfo = CultureInfo object
return Convert.ToDateTime(printQuoteDate , cInfo);
}
}
So my question is when I will use the above property in my code, will it have the corrosponding culture information that I am setting in its get method, or I will have to use the same CONVERT code for formatting date time. The restriction here is that the Property should return only DateTime type.
VS 2008 - Why Getting Object Reference Not Set To Instance Of Object
Jan 21, 2013I added a panel and a button to a page and worked fine. I then moved it to a master page and created a web content page to use the laster page and I get Object reference not set to an instance of an object.
Designer page:
Code:
style="background-image:url('home16.png'); cursor:hand; background-repeat:no-repeat; background-position:left; padding-left:6px; background-color:#E2E2E2;"
Runat="server" BorderStyle=None Text="Home" Width="90px" />

Runat="server" BorderStyle=None Text="Charts" Width="90px" />
[Code] ...
Code page:
Code:
Dim Menu1Color As String = "#C6C6C6"
Dim Menu2Color As String = "#E2E2E2"
btnHome.Attributes.Add("onmouseover", "this.style.backgroundColor='" & Menu1Color & "'")
btnHome.Attributes.Add("onmouseout", "this.style.backgroundColor='" & Menu2Color & "'")
btnCharts.Attributes.Add("onmouseover", "this.style.backgroundColor='" & Menu1Color & "'")
[Code] .....
It works fine in a reguler web form but not in the master form.
C# - How To Create A DateTime Object Not In The Current Culture?
Jul 29, 2010I'm really drawing a blank on this one. I've been working on globalization but the DateTime seems to always revert back to the CurrentThread's culture.
I've got a textbox with the date expressed as a string:
// the CurrentThread's culture is de-DE
// My test browser is also set to de-DE
IFormatProvider culture = new System.Globalization.CultureInfo("de-DE",
true);
// en-US culture, what I'd ultimately like to see the DateTime in
IFormatProvider us_culture = new System.Globalization.CultureInfo("en-US",
true);
// correctly reads the textbox value (22.7.2010 into a datetime)
DateTime dt= DateTime.Parse(txtStartDate.Text, culture,
System.Globalization.DateTimeStyles.NoCurrentDateDefault);
// correctly produces a string 7/22/2010
string dt2 = dt.ToString(us_culture);
At this point I want a DateTime that's in en-US I've tried both:
DateTime dt3 = Convert.ToDateTime(dt2, us_culture);
DateTime dt3 = DateTime.Parse(dt2, us_culture);
But both produce de-DE DateTimes. My motivation in asking this question is the rest of the business logic is going to be calling dt2.toString() and will result in an incorrect date time string. I realize I could change toString() to be toString(us_culture) but I'd rather not change all of the rest of the business logic to accomodate this change.
Is there a way to get a DateTime in a culture other than the CurrentThread's culture?
Insert And Query A DateTime Object In SQLite DB From C#?
Mar 17, 2010Consider this snippet of code:
string sDate = string.Format("{0:u}", this.Date);
Conn.Open();
Command.CommandText = "INSERT INTO TRADES VALUES(" + """ + this.Date + """ + "," +this.ATR + "," + """ + this.BIAS + """ + ")";
Command.ExecuteNonQuery();
Note the "this.Date" part of the command. Now Date is an abject of type DateTime of C# environment, the DB doesnt store it(somewhere in SQLite forum, it was written that ADO.NET wrapper automatically converts DateTime type to ISO1806 format)
But instead of this.Date when I use sDate (shown in the first line) then it stores properly.
My probem actually doesnt end here. Even if I use "sDate", I have to retrieve it through a query. And that is creating the problem
Any query of this format
SELECT * FROM <Table_Name> WHERE DATES = "YYYY-MM-DD"
returns nothing, whereas replacing '=' with '>' or '<' returns right results.
So my point is:
How do I query for Date variables from SQLite Database.
And if there is a problem with the way I stored it (i.e non 1806 compliant), then how do I make it compliant
VS 2008 - MSChart Using DateTime On X Axis?
Mar 29, 2010I have installed the asp.net MSChart control for VS2008 and set up a chart on my webform. I am using DataBindTable in code to bind data from a LINQ query. The data for the x axis looks something like this:
Date/Time
15/03/2010 08:00:00
15/03/2010 14:00:00
15/03/2010 20:00:00
16/03/2010 08:00:00
16/03/2010 14:00:00
etc
When the chart displays the X axis only displays multiple dates, and not times, no matter what properties I try to change.
Web Forms :: Globalized Datetime Object As Sql Query Parameters?
Dec 28, 2010I have an application which uses globalization, hence the datetime objects are globalized based on current culture. These datetime objects are passed as sql parameters for a select query. The database stores the datetime in only one format (en-US style). Although the query is parameterized the final query generated does not contain converted values (format that Database is expecting).
View 1 RepliesC# - Remove Hours:seconds:miliseconds In DateTime Object

View 3 RepliesDate Javascript Object From IE Can't Be Automatically Bound To Datetime MVC
Jan 14, 2011I have a site that uses a jquery calendar to display events. I have noticed than when using the system from within IE (all versions) ASP.NET MVC will fail to bind the datetime to the action that send back the correct events. The sequence of events goes as follows. Calendar posts to server to get events Server ActionMethod accepts start and end date, automatically bound to datetime objects
In every browser other than IE the start and end date come through as:
Mon, 10 Jan 2011 00:00:00 GMT
When IE posts the date, it comes through as
Mon, 10 Jan 2011 00:00:00 UTC
ASP.NET MVC 2 will then fail to automatically bind this to the action method parameter. Is there a reason why this is happening?
The code that posts to the server is as follows:
data: function (start, end, callback) {
$.post('/tracker/GetTrackerEvents', { start: start.toUTCString(), end: end.toUTCString() }, function (result) { callback(result); });
},
Date Or DateTime Object To Be Independent Of Page Culture
Dec 28, 2010Dim strTime as String = FomatDateForSave("28/12/2010")
Public Shared Function FormatDateForSave(ByVal strDate As String) As Date
FormatDateForSave = Date.ParseExact(strDate,'dd/MM/yyyy', System.Globalization.CultureInfo.InvariantCulture)
End Function
I am expecting strTime to be "12/28/2010" .... But its getting converted to "28/12/2010" The thing is when the operation is performed by FormatDateForSave ... it converts it to "12/28/2010" But when it is returned it is again converted to "12/28/2010"
I have set the Date for Page.Culture to be "dd/mm/yyyy" and want the value to be "mm/dd/yyyy" to be saved in DB.

C# - Mvc LINQ Datetime - Accommodate NewsFillter In The Postsidebar Query In The Pstmt Object?
Nov 23, 2010string NewsFillter = string.Empty;
List<string> PublishDatePostMeta = (from post in postrepository.GetAllPosts()
join pstmt in postrepository.GetAllPostMetas()
on post.int_PostId equals pstmt.int_PostId
where (post.int_PostTypeId == 4 && post.int_PostStatusId == 2 && post.int_OrganizationId == layoutrep.GetSidebarDetailById(SidebarDetailsId).int_OrganizationId) && pstmt.vcr_MetaKey=="Publish Date"

int DatesCount = PublishDatePostMeta.Count();
foreach (string PublishDate in PublishDatePostMeta)

if (PublishDate != "")
{

}
}
var postsidebar = from post in postrepository.GetAllPosts()
join pstmt in postrepository.GetAllPostMetas()
on post.int_PostId equals pstmt.int_PostId
where (post.int_PostTypeId == 4 && post.int_PostStatusId == 2 && post.int_OrganizationId == layoutrep.GetSidebarDetailById(SidebarDetailsId).int_OrganizationId)
&& (pstmt.vcr_MetaKey.Contains(filter) && pstmt.vcr_MetaValue.Contains("true"))
select post;
The thing is that how NewsFillter would be accomdated in the postsidebar query in the pstmt object after true ( i would be putting it in contains,equals join or what). is there any way that a chunk (between &&s) return enumerable and i can get away with this. at this moment it is not allowing that
