Data Adapter in Ado.net - ado.net

An attempt to attach an auto-named database for file C:\Users\vinod\Documents\Visual Studio 2013\WebSites\App_Data\aspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
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.

from the exception message I guess that you are using LocalDb ... so you could just start Microsoft management studio and enter "(localdb)\v11.0" as server name ... then expand the "databases" node and remove everything that sounds like "aspnetdb.mdf" ...

Please help !
First update your web service references used in your application.
If web service references are not get updated, then check all files and folder containing source code files in your web service project solution and rebuild it and then update web references used in your project.
Else if its working fine then you need to check your network services used by your development server and windows firewall settings as suggested in above solutions.
I also encountered same problem and I came to know that I was referencing wrong folder having same name but used in another solution.
Enjoy codding.

Sync Framework 2.1 - Deleted row information cannot be accessed through the row

I am trying to sync SQL express to a central SQL 2008 r2 database. When I delete a row in the central database and try to sync it to the express database with a download-only scope, it throws the below error:
Deleted row information cannot be accessed through the row.
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.
Exception Details: System.Data.DeletedRowInaccessibleException: Deleted row information cannot be accessed through the row.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Stack Trace:
[DeletedRowInaccessibleException: Deleted row information cannot be accessed through the row.]
Microsoft.Synchronization.ISyncSession.Start(CONFLICT_RESOLUTION_POLICY resolutionPolicy, _SYNC_SESSION_STATISTICS& pSyncSessionStatistics) +0
As mentioned in the comment I found the problem in the ChangesApplied event handler.
Changed the code to access row values from
table.Rows[i][j]
to
table.Rows[i][j, DataRowVersion.Original]
to fix it.

OFBiz-11.04 deployment in JBoss-5.1.0

In order to get flexibility in load balancing and clustering, I thought of deploying my OFBiz application in JBoss-5.1.0 as per document (https://cwiki.apache.org/OFBTECH/deploying-ofbiz-904-on-jboss-510.html).
Build was successful and I could see all WAR files in server/default/deploy/OFBiz.ear and other JAR files in lib folder. But I am getting a few issues when starting JBoss server. Please take a look and help me if you have any clues.
Issues:
Could not find definition for entity name EntityKeyStore
......................
Could not find definition for entity name JobSandbox
...................
Entity definitions for EntityKeyStore is located in entitymodel.xml of framework/entity/entitydef folder. I could not find this xml anywhere inside OFBiz.ear. (Not only this XML, none of the entitymodel.xml s are found in ear. But no issue with other entities. I do not know why it is so). I checked my database (server/default/data/derby) and found out ENTITY_KEY_STORE there.
The same is the case for JobSandBox.
After this exception, the server seems to proceed with creating dispatcher for each component and it started with accounting. I am getting another issue here.
Could not get root location for component with name [common], error was: org.ofbiz.base.component.ComponentException: No component found named : common
.....
....
....
---- exception report ----------------------------------------------------------
Error processing include at [component://common/webcommon/WEB-INF/common-controller.xml]:java.net.MalformedURLException: Could not get root location for component with name [common], error was: org.ofbiz.base.component.ComponentException: No component found named : common
Exception: java.net.MalformedURLException
This exception is repeatedly printed in log file. And down the line, the same kind of exception is thrown for other components like commonext, accounting and ecommerce.
After these exceptions "Could not find definition for entity name Tenant" is also thrown.
My OFBiz application uses a multitenant environment. Any help is greatly appreciated.

Entity Framework, and connection strings

I'm trying to deploy my .net website to a shared hosting server. I'm getting the following error when entity framework tries to connect to the database:
Server Error in '/' Application.
Login failed for user 'PHX3\Iusr_9086819'. 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.

Here is my connection string, with sensitive data removed:
<add name="CoreEntities"
connectionString="

provider=System.Data.SqlClient;
provider connection string='
Data Source=*****.db.*****.hostedresource.com;
Initial Catalog=kshoultz;
integrated security=True;
multipleactiveresultsets=True;
App=EntityFramework;
User ID=*****;
Password=*****;
Database=*****;
'"
providerName="System.Data.EntityClient" />
I think integrated security should be false - that means not to use a user id and password. Initial catalog is the name of the database - did they tell you the database was named kshoultz? (Could be, I don't know any different, but if you created a database and chose a name, that's the name you want to use). Has the password got any characters that aren't letters/numbers? You have to encode them, for example is your password is Love&Peace you have to say Love&Peace
Have you asked GoDaddy support?

Crystal report 9.2, incorrect log on parameters

Background;
The Web application is developed for .Net framework 4.0. It has crystal report 9.2 integration. Application runs on Integrated Windows Authentication. The crystal reports are working fine when we execute, from solution running under Visual Studio 2010. When the same report are deployed to server (Web Server- OS: Windows Server 2003-SP2-32bit. DB Server- OS: Windows Server 2003-32bit) following error occurs, incorrect log on parameters. Crystal Report Runtime Engine for .net framework 4.0 has been installed in web server. Reports are configured to work on ODBC, System DSN with SQL Server driver. This drivers runs on SQL Server user account which has permission on database. There are no logon parameters passed from application. Just to verify, solution of passing the logon parameters from application is also tried, but the problem is not resolved.
Note: To resolve full access has been provided to IIS_WPG account on folder: C:\Windows\Temp, C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and web application.

You need to change the profile IIS is running under to a domain account or change your web.config file to impersonate the user. Otherwise you will need to apply logoninfo for the report.
