Error : The Entry 'asp:System.Web.UI:System.Web.Extensions / How To Fix This
Jan 27, 2011We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
The web.config file includes the following:
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode="Never" theme="esl_theme">
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.
Web Service Returns IndexOutOfRangeException With Arguments?
Dec 15, 2010I have the following web service:
[ScriptService]
public class Handler : WebService {
[WebMethod]
public void method1() {
string json = "{ "success": true }";
System.Web.HttpContext.Current.Response.Write(json);
[code]...
The first method accepts a traditional html form post and response writes a JSON string to the page.The second method accepts a JSON value posted via AJAX and returns a serialized object.Both these methods work fine on their own but when put together in the same web service I get this error when calling method1:
System.IndexOutOfRangeException: Index was outside the bounds of the array.
When I remove the arguments from method2 they work.Can anyone suggest why this is happening?
Edit:The problem spans from the argument type of method2. If I change it to a string or simple data type it works fine.As Joel suggests it's probably because Dictionaries can't be serialized.This doesn't seem to affect my requests sent by ajax and only breaks direct form posts to this handler.Therefore my workaround is to put the form post handlers in a separate file by themselves.Not ideal but works for my application.
Avoid IndexOutOfRangeException Indexing DataReader Columns?
Feb 9, 2010I am having a little trouble with an 'IndexOutOfRangeException'. I think it is because when the code tries to get the DateModified col from the database it sometimes contains NULLS (the users haven't always updated the page since they created it).
Here is my code;
s = ("select datemodified, maintainedby, email, hitcount from updates where id = @footid")
Dim x As New SqlCommand(s, c)
x.Parameters.Add("@footid", SqlDbType.Int)
x.Parameters("@footid").Value = footid
c.Open()
Dim r As SqlDataReader = x.ExecuteReader
While r.Read
If r.HasRows Then
datemodified = (r("DateModified"))
maintainedby = (r("maintainedby"))
= (r("email"))
hitcount = (r("hitcount"))
End If
End While
c.Close()
I thought (after a bit of msdn) that adding;
If r.HasRows Then
End If
after adding I am still getting the same old IndexOutOfRangeException
(ps, I have tried datemodified as string / datetime)
Forms Data Controls :: ObjectDataSourceView.BuildDataObject Throwing IndexOutOfRangeException?
Jan 27, 2010I've got a FormView bound to an ObjectDataSource. The FormView/ODS selects and displays my data correctly but when I change the data and try to update,nothing (seemingly) happens.Stepping through the code and digging deeper into the stack trace and output window,I figured out that the following sequence of events happens:
- The ObjectDataSource drills down to System.Web.UI.WebControls.ObjectDataSourceView.BuildDataObject to create the object I specified in the "DataObjectTypeName" property
[code]...
- Here is where the IndexOutOfRangeException happens. Sometimes one or two of the data object's properties will be set, sometimes none. Either way, the exception is thrown and the sequence is stopped (the business object's update is never called).
- The exception is not thrown inside any of the properties' set methods.I'm assuming that the exception is happening when BuildDataObject is using Reflection to find my data object's properties (GetProperty() etc.. ). Since I can't see the source code of BuildDataObject and the debugger won't give me any more information, there is no way for me to see which property (if any) is causing this.I double checked the names and types of all 27 of the data object's properties.

View 2 RepliesSystem.EnterpriseServices.dll Error With .NET 3.5?
Jan 17, 2011I'm trying to create a test app to work out some code to connect to an Oracle database. The target project is in .NET 3.5 so that's the framework that I choose for the project. However, when I attempt to set that as the target framework and run the app, I get the error:

I've tried reinstalling .NET 2, but I can't get a dialog with an option to do so to appear. When I try to change the program settings, either the installer will load and then just exit, or it will load and tell me I can't uninstall.

SQL Bulk Insert And Operating System Error 3
May 14, 2010I have two servers. One is a web server and one is a sql server. What I'm trying to do is as follows: User uploads a document to a web site. File is stored on a web server in a directory, verified that it's a certain type of file, and saved. When the user presses a submit button, the page is uploaded and the Onclick event triggers a sql bulk insert (not on the same web server.) That's it in a nutshell. The basics of this page are done. The file can be saved but for whatever reason, I'm getting a Operating system error code 3(The system cannot find the path specified.) I've modified the machine.config on the web server to impersonate another user. I've made sure that the directory in question can be reached from both servers (and it can.) I can open/edit/delete the file from the directory from both sides, but evidently that's not the issue.
View 2 RepliesAfter Upgrading / Getting Contains Is Not A Member Of System.array Error
Aug 17, 2010I have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.
I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.
Here is my linqkit query:
Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))
Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.
My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.

ADO.NET :: Getting Error - System.InvalidOperationException: Operation Is Not Valid
Mar 29, 2011I am using static class to do every job related to Database. In this class Connection Object is static but i am creating command object in the method. I read a form post here [URL] about creating connection object local. If we do like that how can we use Connection pooling? There is an example code below.
I am creating a connection object with pooling (Validate Connection=True; Min Pool Size=10; Max Pool Size=200; Incr Pool Size=10; Decr Pool Size=5;). I am expecting to use connection pool by static connection object (this obje has a connection poll) with dynamicly created commands. Am I wrong? Sometimes i am getting "System.InvalidOperationException: Operation is not valid due to the current state of the object." error. Is it because static connectin object?
