Error Executing CLR Stored Procedure "Item has already been added. Key in dictionary"

Hello, I'm consuming a web service through assemblies in a Sql Server 2005 database. The client was made with VB.net 2005. Everything was fine in the deploy phase but once I compile the assembly generated in my sql server database and try to execute the CLR stored procedure defined in the assembly it crashes throwing the following error: Error: There was an error generating the XML document.

I tried almost everything but nothing seems to work: Already checked the enviroment variables and . I would appreciate any help you can provide me.  PD: I'm using WSE 3.0. Thanks, Andres Diab.

Error Executing Package for Analysis Cube in GP 10 (More than one code)



i installed GP 10 in SQL 2008 and windows 2008, and then installed the analysis cubes.

when try to execute the package DynamicsGP__to__Package_Master i got the error:

Error: the column "INTERID" can not be processed because more than one code page (1252 and 1256) are specified for it.

Error: the column "CMPNYNAM" can not be processed because more than one code page (1252 and 1256) are specified for it.

after searching, i found answers by Mr. Mohammad R. Daoud about removing any linked server, so i take a copy of the data and installed in another test server but it gave me the same error. i checked the test server for any linked server but there isn't any.

what should i do? i need to to make it work in the test server, and also in the real linked server.


[Entity framework] Strange error executing a sql query


Hello to all,

I have a strange error, I've tried to search for it before writing this post but I wasn't able to find out a solution yet.

I'm executing a query using ExecuteStoreQuery against a MySQL database, but it throws an exception reporting that there's a syntax error in my SQL.

I've tried to copy&paste the sql query into the MySQL tool and it works nicely, giving the correct results.

I've tried to open manually the connection and using CreateCommand to use it the "old way".

My query is a bit long, 4000 chars more or less, could it be the problem?

Thank you very much!


Error: Workflow service unexpectedly unloaded from memory while executing a ReceiveActivity.



While calling the workflow(through RecieveActivity) when it has been persisted into the database, below error is being thrown:

Workflow service unexpectedly unloaded from memory while executing a ReceiveActivity. Make sure that the the workflow does not contain any blocking activities within a ReceiveActivity.  (Fault Detail is equal to An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is: System.InvalidOperationException: Workflow service unexpectedly unloaded from memory while executing a ReceiveActivity. Make sure that the the workflow does not contain any blocking activities within a ReceiveActivity.  ).

This error crops up when workflow is being loaded back into the memory from the persistence store(database) for further processing. Workflow instance is being persisted into the database after calling  a long running process to reduce the load into the system memory. When the long running processes finished its processing it calls the workflow by calling the operation contract associated with the Re

Error while executing workflow persistence


I get the following error while running my workflow, on average of about 1 in 200 instances.

An error processing the current work item has caused the workflow to abort.  See the inner exception for details. InnerException Message: The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}SaveWorkflow was interrupted by an error.


An error processing the current work item has caused the workflow to abort.  See the inner exception for details. InnerException Message: The operation did not complete within the allotted timeout of 00:00:00. The time allotted to this operation may have been a portion of a longer timeout.

The problem seems to be with persistence not happening within 0 seconds, but I wouldn't have a clue where i can increase this???  Remember that this workflow normally runs fine????

Error seen when executing sql string via webpart


I have loaded my first customized webpart into my live site.  This is written in C# and performs a search on an external database, not Sharepoint one.

Whenever I select the button to pass in some criteria, I see an error message"Login failed for user NT AUTHORITY\ANONYMOUS LOGON"   When I look in the SQL Log files I see:  "Error: 18456, Severity: 14, State: 11.  Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT IP Address]"

Have googled this message , but not found anything that relates to my problem.  Enable Anonymous Access is unchecked in IIS -> Web Site -> Directory Security.  Connection String has: Integrated Security=SSPI

Dialogs and ViewModel - Using Tasks as a Pattern

The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.

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:


CALL_ISAPI_EXTENSION DllName="C:\Windows\Microsoft.NET\Framework\v2.0.50727\\aspnet_isapi.dll"

Inserting personal error message in ValidationSummary



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
