I have one asp.net application , when i run this application in the visul studio it run successfully But when i deploy this aaplication and run from iis its show me this error: "Operation must use an updateable query" I am using VWD 2008 express edition database: Foxpro
View 2 RepliesI executed the following sql command, and got error "Operation must use an updateable query.".
[Code]....
The database is access 2003. The tables are T1 (code (key), n) and T2 (code(key),num). Why do I get this error and how do I solve it? EDIT: Found solution somewhere else.
I'm trying to do a very simple update in Access:
[Code]....
and am getting this error. Both contact_information and temp_contact_information are tables. The subquery
[Code]....
works fine by itself, and if I replace the subquery with the result of the subquery, for example:
[Code]....
it also works. What the heck?
This is the first time i am using ms access database for the c# asp.net .
I am getting the following error when i try to insert the record.
Operation must use an updateable query.

I have the following query:
Dim roommates = From p In dbroom.Residents _
Where p.room = queryStudent.First.r.id _
Where p.building = queryStudent.First.b.id _
Where p.year = year _
Where p.semester = term _
Select p.person_name
It currently returns no results. I was getting an error when attempting to bind this resultset (since it was empty) to a repeater in ASP.NET, so I attempted to escape it:
If roommates.Count() = 0 Then
Dim nomates As String = "No current roommates."
rptrRoommates.DataSource = nomates
rptrRoommates.DataBind()
Else
rptrRoommates.DataSource = roommates
rptrRoommates.DataBind()
End If
But I still get the same error:
The method 'First' can only be used as a final query operation. Consider using the method 'FirstOrDefault' in this instance instead.

I'm using a very simple Ldap query in my asp.net mvc 2.0 site:
String ldapPath = ConfigReader.LdapPath;
String emailAddress = null;
try

I'm running it under the default app pool.
The following query uses join operation, i want the same query to execute without using join operation. Is it possible to do so? If yes than how can i do it?select jname, jcode from heardt inner join judge ON heardt.jud1 = jcodThe reason i am trying to do this is because i am using odbc connection for mysql and join operations are not getting executed at all as web page is loading for infinitely long and not giving any output. That is the reason why i want to try without using join operation

We have deployed an application in iis 6.o. We set cache for 1 hr in that application so that the updated data in the back-end will be visible by the user after 1 hr. If the requested data not available in cache it will fetch from database directly.
Is there any way that I can clear this cache in between 1 hr for some of our testing.
Resetting the website and app pool and deleting temp asp.net files didn't work, I have tested that.
I developed an application locally using the Visual Studio 2008 built-in web server and it is running nice and neat on every single browser. When we deployed it on the IIS6 and open it on IE8, there are rendering issues. The fonts are bigger than the other browsers (which are still nice and neat) and some components just moved around. The generated HTML is the same as the others.
View 2 RepliesI'm trying to deply a 3.5 Net application developed in VS Web Express and built using the asp compiler. This works fine when tested using an eval version of Win 2008 Standard server on a VM. However when installing on a production Win 2008 Standard server it fails with the message can not load assembly as it has not been signed or the signature does not match. How come this works in one and not the other? The live server has symantec AV installed and running? If this the reason? Have a bit of knowledge ( as all devlopers do) of OS's but am totally stumped by this. If I could even replicate it on the development machine would allow me to move forward. Do i need full Vis Studio? Do I need to sign the DLLs?

I am a newbie C# developer. I have been getting my feet wet writing a C# web app for my department. I am using the following system:
Windows 7 Professional Visual Web Developer 2010 Version 10.0.30319.1 .Net framework 4.0.30319. IIS version 7.5.7600.16385 Internet Explorer 8.0.7600.16385CO SQL Server 2008 R2
When I run my application in the VWD debugger everything works fine and looks the way I want it to work. When I deploy to IIS (which is on the same box that I develop on) I start having some issues. Here is a breakdown of the problems I am having:
I have an asp:menu control with orientation set to horizontal. When I initially load the sitre after a deploy the menu displays correctly. But when I go to a different web page in the app the menu switches to vertical and the width of each menu item spans the width of the div that surrounds it. On the same page that causes issues with the asp:menu I also have asp:ComboBox controls that are used to filter information on the page. The combo boxes just look like text boxes. The data that should populate the boxes is not present.
I also have some ajax accordion controls contained in asp:updatepanels, neither of which work. The accordion controls are all expanded, and I cannot collapse them. If I trigger an update the entire page reloads instead of just the specific control.
I do not receive any errors when I browse to the page that causes the problems. It loads just fine everything is just jacked up. Like I said, everything works flawlessly in the VWD debugger. I know the VWD debugger does not use IIS, which makes me think this is an IIS issue, but I do not even know where to start to pinpoint the problem.
I have to design asp.net application which has to work on kiosk system.

View 1 RepliesWe have an ASP.NET application running on a webfarm. When we release a new version and copy it to the production servers, occasionally it happens that after a few hours the application reverts to a an earlier code base.Have anyone else experienced something like this? Would sharing an application pool between two applications running different versions of the code make this happen?

"The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. "
My stracktrace points to line 256, which is the ending french bracket of my GetMimiFromFile function.
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
