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


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.

SharePoint 2007 Central Admin - blank page, isapimodule error in IIS


I've got a Windows 2008 SP2 server runing x64.

When i try to access the SharePoint Central Admin site, I just get a blank page. No errors in the Windows logs, nothing showing up in the SharePoint logs. The IIS log shows a 500 error.

I enabled Failed Request Tracing for the 500 status code, which gives me the following information:

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

ScriptManager CompositeScript Error: A script reference cannot be included multiple times in composi

I am getting the following error using the CompositeScript feature of the ScriptManager.  I have ScriptManagerProxy in several different usercontrols that use CompositeScript to add whatever JS files they need.  Sometimes there are duplicates which would get removed by the script manager, but that is not happening with the Composite Scripts.  Looking at the stack trace, it calls RemoveDuplicates but for some reason it doesn't do so.  Is this a bug?  Is there a workaround or a hotfix? Thanks! A script reference cannot be included multiple times in composite script references. Stack Trace: [InvalidOperationException: A script reference cannot be included multiple times in composite script references.]   System.Web.UI.ScriptManager.RemoveDuplicates(List`1 scripts) +698   System.Web.UI.ScriptManager.RegisterScripts() +328   System.Web.UI.ScriptManager.OnPagePreRenderComplete(Object sender, EventArgs e) +113   System.Web.UI.Page.OnPreRenderComplete(EventArgs e) +8695102   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1029

Error handling, multiple error messages

Hi all. Have you noticed that sql server catches only last error message? Try to run this: exec('create table #t ( t1 timestamp not null default 0 )') You get: Msg 1755, Level 16, State 0, Line 1 Defaults cannot be created on columns of data type timestamp. Table '#t', column 't1'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors. Now try to run the same thing in try catch: begin try exec('create table #t ( t1 timestamp not null default 0 )') end try begin catch declare @Error varchar(max) set @Error = error_message() raiserror(@Error, 16, 1) end catch The error message this time is: Msg 50000, Level 16, State 1, Line 10 Could not create constraint. See previous errors. Does anyone have any better ideas how to handle sql server errors? Thanks      

Sharepoint 2007 Upload Multiple Documents error on Windows Vista

Hi all, I am having an issue uploading multiple documents from a share using the "Upload Multiple Documents" on the toolbar in a document library. The user experiencing this problem has a Windows Vista machine that recently replaced XP. They have mapped shares that they use. The shares work fine in windows explorer, but when you click the + next to the share through the "Upload Multiple Documents" function on sharepoint, the machine thinks for a while, then removes the + and shows no documents. Anyone know why this is happening?

Allow blank spaces in textbox

Hi,   I have a simple issue..the user types his/her name in a textbox. Accidentally if a space is entered after a name or before, is it possible for me to trim it while accepting and not raise any error (which actually arises when the textbox is empty)? Actually, not raising an error is the issue!    Thanks!

Error: Multiple Entries found

Our company has been migrating from .Net 1.1 to the new version 2.0 and I've
noticed the following error which happens quite often and requires an IIS
reset to recover web serivce functionality.

We are using WSE 1.0 sp1 and the <passwordProvider> declaration is in the
web.config file located in the root folder for the web service in question. 
I've searched and can't find the password provider in the machine.config or
file more global in scope.

Any clues would be much appreciated!

Here's the error:

System.Configuration.ConfigurationErrorsException: Multiple
<passwordProvider> entries were found in the configuration file, but only one
is allowed.

Error pop out when multiple EWA used in one page



I met one problem in SharePoint Designer 2010.

As my customer's requirement, I created a lot of PivotTables and PivotCharts in multiple sheets in one Excel file. Now I need to integrate all the PivotCharts in to one single page, all the PivotTable need to be show on the page at the same time, so I cannot use the named Item drop-down list.

for this requirement, I inserted a lot of Excel Web Access web parts in the page, all the EWAs connect to the same source file(the Excel file mentioned above) which has already located on SharePoint Server, then I am not able to open the page in browser(IE8).

It will show two kinds of information when failed to open the page:
1.It shows: The web page cannot be displayed.
2.The 2nd will show one dialogue asking for user credentials continuously.

Do you have any idea about it, or if you have other methods to make all the PivotChart show on the page simultaneously, please let me know.

multiple column with dropdownextender encounter jscript error


In order to have a multi-column dropdown list, I combined a textbox, a dropdownextender, and a panel with gridview inside it. Without update panel, 
everything works ok except postback causes flashes and I do not want that. So I have to user the update panel. And now, I got the error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.
Anyone knows how to fix this problem?

Asp.net code:

<script type="text/javascript"> var checkForClose = "true"; function setOKToClose() { checkForClose = "false"; } function movePnlScroll(num) { if (num >= 10 && num < 25) { // var pnlConnectorPerformance = document.getElementById('ctl00_ContentPlaceHolder1_pnlConnectorPerformance'); var pnlConnectorPerformance = document.getElementById('pnlConnPerformance'); pnlConnectorPerformance.scrollTop = num * 22; } if (num >= 25) { // var pnlConnectorPerformance = document.getElementById('ctl00_ContentPlaceHolder1_pnlConnectorPerformance'); var pnlConnectorPerformance = document.getElementById('pnlConnPerf

Making the Validation Error on TextBox thicker


A few of my users would like the validation error on the textbox to be more prominent. 

I have added this to my ResourceDictionary...

<Style TargetType="{x:Type TextBox}">
  <Trigger Property="Validation.HasError" Value="true">
   <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/>
   <Setter Property="BorderThickness" Value="3" />
   <Setter Property="FontWeight" Value="Heavy" />

The text does indeed go heavy on validation, but the red outline stays the same.  I am guessing BorderThickness is not the correct property to set.

  1. What is the appropriate property to set?
  2. Is there a place to look at what the WPF default is for TextBox Validation.HasError?
