Error "user does not have permission to perform this operation" with User Instance = True.

  

I setup SQL Server 2005 / SQL Express. All works fine in SQL Server 2005.

I am connecting to a SQL Database from VS 2005,  Tools/Connect to Database. I set the Data Source to "Microsoft SQL Server Database File (SqlClient)" (meaning SQL Server Express) and User Instance = True, and Integrated Security = True.

The above is working successfully on all machines except my Laptop. On my Laptop, I am getting this error "user does not have permission to perform this operation". On my Laptop, if I change User Instance = False, it works fine. Also, If I connect to SQL Server 2005 it works fine only if User Instance = False.

I tried all kind of security changes, nothing worked. For example, I setup Everyone as Full Control for the Folder and the MDF File of SQL Server. I gave my user ID as sysadmin role in SQL Server Express. Also, I enabled creating User Instance form SQL Server Express, Nothing is working.

Appreciate your help.

Tarek.

Response.Redirect cannot be called in a page callback error message.

  

Hi.  I'm using the Dundas Chart Controls in VS 2005.  These controls are built utilizing AJAX.  I have a basic page with a dundas chart control containing a funnel chart.  The funnel contains Quotes, Sales Orders and Invoices.  When the user clicks on the control, I want to determine whether they clicked on Quotes, Sales Orders or Invoices and transfer to the appropriate Details Page.  I've got the code working to determine which transaction type they clicked on; but, I get the "Response.Redirect cannot be called in a page callback." error when the page tries to redirect.  Note: I get a similar issue if I try server.transfer.

Suggestions?

 Here's my code:

Dim hitTestResult As Dundas.Charting.WebControl.HitTestResult = Chart1.HitTest(e.X, e.Y)

            If Not (hitTestResult Is Nothing) Then

                Dim clicked As Dundas.Charting.WebControl.DataPoint = hitTestResult.Series.Points(hitTestResult.PointIndex)

                Select Case hitTestResult.PointIndex
                    Case 0

                        Response.Redirect(

Error when trying to export gridview to Excel - RegisterForEventValidation can only be called during

  
I have a pretty basic vb.net page that has textbox control on it and a "generate" button that when clicked, fills a datagrid.  That all works great, but when the user clicks the "Export to Excel" button, I get this error.. RegisterForEventValidation can only be called during Render(); 

Here's my code behind, I thought I included everything I needed...

IsapiModule Error 500 Issue

  

I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

Handling 404 page not found with Error page

Inserting personal error message in ValidationSummary

  

Hi,

I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Jscript error: Object does not support property or method

  

 Hi, 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.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Type or namespace error.

  

A couple of days ago I started getting an unusual behavior when compiling Website projects. I have referenced class libraries added to my bin folder that are also correctely referenced in using statements in my aspx.cs code behind. When I compile, I get the 



Error 4 The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?) C:\Dev\Fiscal_Portal\Implementation\FMS Portal Site_new\App_Code\BLL\DataTables.cs 1 7 C:\...\FMS Portal Site_new\

The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?)

error message that would typically be received when the dll has not been added as a reference or added in a using statement.


I can eliminate the error by adding an

HTTP Error 403 - Forbidden

  

(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????

Thanks,

Rick

Insert Error not helpful

  

Hi,

I am using VS2010

When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.

Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.

Could you please shed some light?

Error when updating. Supposedly updating ID without being asked.

  

 

Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.
A member defining the identity of the object cannot be changed.
Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!


urlrouting - page not found error

  

I have a dynamic data site setup and running locally fine from vs 2008.

When i deploy to a remote windows 2003 server (IIS6), all the pages also work ok apart from one page/table.  I can access it's list page,  but the edit and insert pages throw 404 errors.

I'm thinking it's a url routing/hosting issue as i've copied back the database from the remote server and it all works fine on my local machine.

Is there anything i can do to debug this behaviour?

Below is my register routes entry from the global.asax
