dateTime filter in sql

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :Windows Application

i have a textbox to enter date with date format dd/mm/yyyy HH:mm and i need to filter the record by this date format

in cs, i parse datetime as belows:

CultureInfo provider = CultureInfo.InvariantCulture;

 DateTime a = DateTime.ParseExact(FmText, "dd/MM/yyyy HH:mm", provider );

in sybase, my sql is :

where (convert(varchar(12),date_field,103)+' '+convert(varchar(5),date_field,108) ) >= 'dd/mm/yyyy HH:mm'

i found that when the date time format in PC settring is different, then i can't filter the same data. how can i ignore the PC setting dateTime???? so that i can filter right data.

Datetime filter value pass to BCS stored procedure parameter


I have data coming from one of the stored procedures that has startdate and enddate as parameters.I have created a business data webpart tht accepts this ECT.When I give the start date and end date in this format----> 2010-02-02 00:00:00Z,I can able to get the data from the database.

               As this is not a feasible approach,I have used a two datetime filters that has calendar control attached to it,so that user can use this to pick the start date and end date.Now,my issue here is when I choose the startdate and enddate,ECT is not accepting the format of the date that these filters are passing.I have changed the filter descriptor LOBDateTimeMode to "Local" in the external content type,but still I am receiving the same error.Does any one has any solution for this??

Using jQuery to Filter Table Rows

The project is using the .net GridView control, so I had limited control over the output HTML code. Still, I think this code can work for most tables. One thing to notice: you should use the class "filterable" on your table or on one of its parents for the code to work.
First, we need a text box:

GridView Multiple Filter AJAX Control

This AJAX control enables the user to filter data within any column inside a GridView. The user can add multiple filters and can delete existing ones too.

Where to Filter the companies returned by the EF?



I am just starting with dynamic data. I have an enttity framework called UsersModel.edmx.

It returns a list of all companies in the tblCompany table. This list is really big.

I need to filter the list returned to all user controls on the client so that it only returns the company that have a CompanyTypeId= 2 or CompanyTypeId= 3 and company name != "".

1 - Is it possible to filter the company list returned on the server so that I can filter only once for all the controls that use that on the client?

My ideas was to do something like this using linq and lambda but I am not sure how:

return tblCompanys.Where(c => c.CompanyTypeId == 2 || c.CompanyTypeId == 3 && ).Where(c=>c.CompanyName != "").OrderBy(c => c.CompanyName).Distinct().OrderBy(c=>c.CompanyName);

2 - I have created a partial class and a metadata class and added the DisplayColumn attribute to use the company name and sort by company name ascending.

Could I use the code to filter the returned companies in this? where?

namespace MarsMedicalModel
    [DisplayColumn("CompanyName", "CompanyName")]
    public partial class t

Filter by Computed Column



After looking for a driver to open legacy dbf drivers to connect, the next level trouble a have is this one:

first, i can retrieve the data but when trying to filter by a parameter (somesc columns) i get an error.

The error says about the database can't determine some blah blah!

The error is a columm tha is formated (  1234  ) about  8 space, fixed. The values in the query appears like that. I resolve this by Trimming Ltrim(ColumnName) and i get this (1234).

Now in SqlExpress, how can i filter by the new Trimmed Expression? (This is a primary key that the DBF use)


SELECT column1, column2, column3


SELECT Ltrim(column1) as NewExp, column2, column3
Where NewExpre = @NewExpres                  -Error-


LDAP nested groups filter


Hi all,

In my organization we use nested groups.

For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.

We may assume that no other group in the LDAP has "kuku" in the name.

I need to create a filter which will return all the users which belong to one of the "kuku"s group.

Obviously, using this filter will bring only the head kukus

(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=.rest of the group DN.))

How can I use wild card to fetch all users which belong to any kuku?

For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))



Urgently Need Help : Unrecognized Tag Prefix or device filter 'CR'


I have download and installed the Crystal Report for 2010 from my Visual Studio 2010. 


Problem 1 :

When I create a new crystal report in the Project, the aspx created code below :

<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"
            AutoDataBind="True" GroupTreeImagesFolderUrl="" Height="1202px"
            ReportSourceID="MemberList" ToolbarImagesFolderUrl="" ToolPanelWidth="200px"
            Width="1104px" />
        <CR:CrystalReportSource ID="MemberList" runat="server">
            <report filename="MemberList.rpt">

 but there is error : unrecognized tag prefix or device filter 'CR'


Problem 2 :

The vb code of the crystal report that I had created has 'ComponentModel is not a member of 'MYPROJECT.system'



System.DateTime.AddDays: Value to add was out of range.


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 irreproducably. 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! Any ideas? Culture settings perhaps?

ISA Server 2004: Developing an Application Filter for Microsoft Internet Security and Acceleration S


The beta version of Internet Security and Acceleration (ISA) Server 2004 is now publicly available. It includes a rich SDK with several extensibility mechanisms that allow third parties to integrate their specialized solutions on top of the ISA platform. In this article, the author explores the application filter extensibility mechanism, which enables you to add high-level application layer filtering capabilities to ISA Server and to provide rich content filtering solutions. He also highlights the new features of the ISA Server 2004 SDK, then moves on to describe how to develop a basic application filter that monitors all data going through the ISA Server, and how to integrate a filter into the ISA Server management console to create a seamless interface experience for your users.

ISAPI Filters: Designing SiteSentry, an Anti-Scraping Filter for IIS


The Microsoft Internet API for IIS, ISAPI, sits between the client and the Web server. Therefore, you can access the HTTP data stream before IIS gets to see it. The project in this article takes advantage of the ISAPI architecture to create a filter that monitors access to a Web site to determine if visits are from typical users or from automated processes designed to pilfer information from your site. The author tracks the regularity of visits to the site to determine the likely source. Once the determination is made, the app either redirects the user or continues to track information about those hits.

MVC 3 Preview 1. Inject value in Action Filter



I was reading MVC3 Preview 1 release and I found this:

Dependency Injection at all levels - We opened up seams for applying the dependency injection when instantiating components of the framework. This allows developers to hook into the creation of models during model binding, action filters, etc.

Does that mean I can inject a value into an Action Filter?

This is a problem I have for a long time and it would be really useful.

How can I do this?
