SQL Server :: Method That Doesn't Use SqlConnection?
Aug 28, 2010
I always use SqlConnection() To open a connection then use the connection to interact database. But I have heard somewhere that opening SQLconnection() take a time. and if on different pages of projects I repeatedly Connect database then It will take long access time always. So I want to know that if there is any other methods which don't use the SQLConnection to interact database and increase the response time of database.
I've just discovered that the X-Requested-With header in IE is always "XMLHttpRequest, XMLHttpRequest" instead of just "XMLHttpRequest". I found the reason in MicrosoftMvcAjax.debug.js at line 280 (MVC 2.0). Seems there is no need to add this header again as it is already done in Microsoft AJAX Library. And because of this IsAjaxRequest extension method doesn't work anymore if there is no X-Requested-With param in the request body. And this make X-Requested-With header useless in IE.
In Firefox there is no problem as it doesn't append but replace the existing header value. Not tested in other browsers.
I am trying to use YAF with Umbraco. The newest version out changed enough where the old integration methods don't seem to work. I have gotten everything fairly far on my own but I have hit a brick wall with this error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have a feeling that YAF is not starting up the database. In previous versions of YAF there was an INIT module that you loaded in your web.config file. This module is no longer there (YAF.Base.YAFInitModule).
i have a masterpage and other pages. i want to use findcontrol method to find a textbox (not on the master page) to check whether it is empty or not.

I have a GridView and on a row being deleted I trigger the GridView1_RowDeleting sub, but I receive an error "LINQ to Entities does not recognize the method 'System.Web.UI.WebControls.TableCell get_Item(Int32)' method, and this method cannot be translated into a store expression." Code is:
Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting ' The deletion of the individual row is automatically handled by the GridView. Dim dbDelete As New pbu_housingEntities ' Remove individual from the bed. Dim remove_bed = From p In dbDelete.Beds _ Where p.occupant = GridView1.Rows(e.RowIndex).Cells(3).Text _ Where p.room = GridView1.Rows(e.RowIndex).Cells(6).Text _ Where p.building = GridView1.Rows(e.RowIndex).Cells(5).Text _ Order By p.id Descending _ Select p remove_bed.First.occupant = "" dbDelete.SaveChanges() ' Increase number of open spaces in room. Dim update_occupancy = From p In dbDelete.Rooms _ Where p.room1 = GridView1.Rows(e.RowIndex).Cells(6).Text Where p.building = GridView1.Rows(e.RowIndex).Cells(5).Text _ Select p update_occupancy.First.current_occupancy = update_occupancy.First.current_occupancy - 1 dbDelete.SaveChanges() End Sub
The specific line erroring out is: remove_bed.First.occupant = ""

i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work. I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page. In my experience, im get this error msg 9 out of 10 times i use javascript in my system. Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything. But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error. Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error. But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum. It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work. So below is my code that i need to use.

What will be the problem.
Whether we can load the value to parent page from popup page even both are in saparate server?

I am writing a Web Application in ASP.NET using C#. Whenever I run it, I get three types of Runtime Javascript Errors.
My Problem is that even though I am running a new Web Application with out any modification, then I also get the same errors.
These are the errors:
Microsoft JScript runtime error: Object doesn't support this property or method at document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false); Microsoft JScript runtime error: Object expected at divSurveyInit(); Microsoft JScript runtime error: Object doesn't support this property or method at enter code here: document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false);
i would like to know if there's something wrong in this asp.net code:
mydatareader = mycmd.executeReader() if myDataReader.HasRow then // Do something end if myConnection.Close()
If i avoid to call a "MyDataReader.Close()" does the connection close anyway ? I ask this because i'm assuming that if call a "MyConn.Close" it automatically close the associated datareader... or am i wrong ?
I got any error from the code, saying 'not all code path return a value', i suspect it is the catch block doesnt return a value. If so, what value should i return?
I am trying to sort in gridview however I got some error message in _dopostback function which shows "Microsoft JScript runtime error: Object doesn't support this property or method" at theForm.submit()
