Error: Encountered multiple versions of the same assembly with GUID...try pre-importing...TlbImp

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net
 

Hi!  Can someone tell me how I can troubleshoot the following error: "Encountered multiple versions of the same assembly with GUID...try pre-importing one of these assemblies".

The website developed in VS 2010 (.Net 3.5). This error is only received on my workstation.  Another person developing the site does not experience this issue at all.  Also, not sure if this matters, but on my workstation the 'Assembly Information...' dialog contains no values even though the 'AssemblyInfo.vb' file does specify values for the title, desc, etc.  The GUID being referenced in the error is the main project of the three projects within the solution.

I tried looking through the GAC, but do not see any references to the projects or DLLs in the VS solution and am not sure what else/where to look.

If I delete the copy of the solution on my local machine and pull down a copy from source control (AnkhSVN) the solution will build with no error.  Once I make any changes, such as adding a new aspx file, then the error is received.

I can provide any additional information needed.

Registering controls of current assembly object reference NOT set error

  

Hi There,

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).

I don't want to register my control using Src, TagPrefix etc. Any ideas?

Thanks


Importing Excel 2007 spreadsheet into WSS 3.0 -- Error Message

  

Hi,

I'm trying to import (Custom Lists >> Import Spreadsheet) into WSS 3.0 and I'm getting the following message: 

Refers to the _layouts

You are not authorized to view this page.  You might not have permissions to view this direcotyr or page using the credentials you supplied. [More stuff here.]

Http ERror 403 - Forbidden

Is this just a permissions problem or is there some other underlying issue?  Should you be able to upload an Excel spreadsheet (with links) into a Custom List?

Thanks!

2008 R2 Tuning Advisor reports "Error: Exception encountered(DTAEngine)"

  
I am encountering an error when I try to use the SQL 2008 R2 Database Engine Tuning Advisor. I create a very simple workload (either by right-clicking a query in SSMS or by loading a file), and click Start Analysis.  In the "Consuming Workload" step DTA aborts, and in the message column displays "Error: Exception Encountered(DTAEngine)". When I click on the error message, I get a dialog box with a title of DTAEngine, and a message "Error: Exception encountered". This is a clean test environment (SQL 2008 R2 Data Center Edition 64-bit, on Windows Server 2008 R2 64-bit, in a VM) against a local database. Any ideas about what the problem is or how to resolve it?

Importing Excel with multiple worksheets via MVC

  
Is there a way wherein I could import data from multiple sheets of an excel file?  Thanks in advance...

run-time error's do not jump to problem line but to assembly with some xml error.

  
  Used too, when there was a runtime error the ide would break at the line that caused the problem. Now I'm thrown into some assembly code with the error System.Windows.Markup.XamlParseException was unhandled   Message='The invocation of the constructor on type 'Main.MainWindow' that matches the specified binding constraints threw an exception.' Line number '4' and line   Which is extremely uninformative and inefficient. I can look down the chain to find the error thrown but this still is not very informative. How the heck can I get it back to the way it used to be? This has something to do with wpf and the assembly code has System.Windows.Markup.XamlReader.RewrapException as the address. I spend anywhere from 10x to 10000x as long because of this. If the code is simple then I still have to read the error code and click a button which takes time.   Also, I'd rather it break on the line and quit the process as it used to do. I don't need JIT debugging.

Error When Deploying Multiple Projects in a Solution

  
We have a solution with 16 projects, where all but 3 are Sharepoint 2010 projects. When we deploy the projects in VS2010 individually, everything is fine, but when we deploy the solution (right-click, deploy), we experience one of two problems: 1. Not all projects get deployed, some just give the following message: "Deployment was not performed for this project because it is a dependent project." 2. Some of the projects (currently always the same three Sharepoint2010 projects) give the following error during the "Recycle IIS Application Pool" step: "Error occurred in deployment step 'Recycle IIS Application Pool': The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout." We don't have any dependencies set up in the projects except for the ones which are automatically created when we add project references. If we do two subsequent solution deployments, the first one will suffer from issue 1 and the second from issue 2 as well. When issue 2 happens, the faulty projects can't even be deployed individually until VS2010 has been restarted.   A Google search has revealed nothing at all. We're at a loss and it's getting to be very frustrating for the entire team. Any help would be appreciated.   Thanks, Bjoern
