LOB System did not find instance

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :C#
 

Hi,

I am attempting to write a program to automatically refresh BDC data in a SharePoint List.  I am receiving the following error:

"LOB system did not find instance"

On this line of code:

identifierValues = entity.FindSpecific(objArray, sysint).GetIdentifierValues();

I'm following this post here:  http://old.sharepointnick.com/blog/Lists/Posts/Post.aspx?ID=59

Any help is greatly appreciated.

Thank you,

DP

System.Data.OleDb.OleDbException: Could not find installable ISAM.

  

Hi, i got the following error while i am trying to get my web application to run on windows server 2003. I've installed 2007 data access components on windows server 2003 but the web application does not seem to work. The codes that i use is as follows:

string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + address + ";Extended Properties=Excel 12.0;"; OleDbConnection objConn = new OleDbConnection(strConn); string strSQL = "SELECT * FROM [Sheet 1$]"; OleDbCommand objCmd = new OleDbCommand(strSQL, objConn);

OleDbDataReader oddReader = null;

objConn.Open();

oddReader = objCmd.ExecuteReader();

.

.

.

.

.

obj.Close()


I've read a lot of forum posts and almost all of them mentioned ab out the connectionstring being wrong. However, when i ran the codes on my local machine, there were no errors. The error only show when i was running on windows server 2003.

I've underlined where the error is pointing to. Please advise. Thanks

Can't find System.Printing

  
Hello, I just installed the trial version of Visual C# 2008 Express Edition with SP1 and the Microsoft .NET 3.5 Framework. I have created a new project (console application) and need to use System.Printing in my project to access the print queue on my machine. However, System.Printing seems to be missing from my installation since I cannot see it in the drop down box that appears immediately after I type in 'System.' in the source file. Do I need some special project setting to include System.Printing? Am I missing something from my installation? Any help would be greatly appreciated. Thanks in advance. Anuj

I have a Java service running on WebSphere Application Server 7.0.  When I invoke the service using my WCF client, I get a 200 OK back in the trace, however my WCF client cannot process the signature in the response message.  I am getting the following error: Cannot find a token authenticator for the 'System.IdentityModel.Tokens.X509SecurityToken' token type.

I have tried setting allowSerializedSigningTokenOnReply="True" in my security binding as multiple forums had suggested.  However, I seem to be getting the same error.  Is there anything else I'm missing?

Event ID 7000 - The system cannot find the path specified.

  

This is a very old prolem that i am getting to. First off I went through anywhere from 4 to 6 or more sessions with a Microsoft TECH and it even escalated a couple of levels of TECH support to boot. I can't remember the details specifically. I do know that I've started with gound up (installed/uninstalled NET Framework versions) installs to where I have all the versions installed. The Service doesn't start either automatically nor manual. I tried the patience of the Support people to fix this last error at that time.

I am starting anew to get the NET Framework Service to work properly . I hope I am in the right support forum.

Thanks

Could not load file or assembly 'vcWebCore' or one of its dependencies. The system cannot find the

  
All,
I have a web project that references a strong-name DLL which contains a HttpModule, it is called vcWebCore.dll.

The DLL is registered in GAC using the gacutil.exe and everything looks fine.
I can see the DLL in my c:\windows\assembly directory with the correct
version (1.0.0.0) and public key token.

However, at runtime I kept getting the error that the vcWenCore module could not be located:

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Cannot find custom tool 'SharePointWebPartCodeGenerator' on this system.

  
When trying to make a change to a web page in a Web Part when I complete the change and attempt to save the ascx file this error shows up as a warning in the Visual Studio 2010 Error List.  When I deploy the Web Part nothing has changed.  I am assuming it is due to this error.  The question here is how does this, the SharePointWebPartCodeGenerator, get installed?  I already uninstalled and reinstalled SharePoint 2010 Server and the SharePoint SDK.
with FindControl() receives: Object reference not set to an instance of an object.   

Hi,

I am trying to "Find" a TableCell in a GridView but receive the error: Object reference not set to an instance of an object.

First in the Page_Load event I set 5 rows to this GridView1. After this I loop through the GridView1 to FindControl("tdCell1") to set a String to each <td> on each of those 5 rows.

But I receive the above error when doing this. I wonder what I can be doing wrong? Thanks!

ReloadTrackingProfiles: System.InvalidOperationException: TrackingListener for instance %0 is not in

  

Hi,

I am hosting Workflows (dll based) in a web application. I created my own TrackingService and my own TrackingChannel (code below). When starting a workflow, everything works fine, all events are tracked. After re-building my solution, workflows, that were running before, do not track anything anymore (although they continue execution). Info: On every build, the build number of all assemblies is increased by default.

I tried to reload the tracking profiles after loading workflows (using workflow.ReloadTrackingProfiles();), but this leads to the error above. 

What am I doing wrong?

thanks,

matthias

 

Here is the code for the tracking service:

    public class EnablerWFTracking : TrackingService {

 

        private TrackingProfile profile;

 

        #region Constructor

        public EnablerWFTracking()

            : base() {

            profile = this.CreateTrackingProfile();

        }

        #endregion

 

        #region CreateTrackingProfile
