Unspecific Web Part Load error

Posted By:      Posted Date: September 30, 2010    Points: 0   Category :SharePoint
 

I cannot figure out why I get the following error when attempting to load/preview a web part.  I think it must have something to do with a bad name reference, but I've reviewed all my calls to other files/assemblies and can't figure this out.  Also, I cannot break-point it since it appears to be failing in a .net control namespace prior to getting to any of  my code:

[SPException: An error occurred when previewing the Web Part.]
   Microsoft.SharePoint.WebPartPages.WebPartPreview.CreateChildControls() +15716021
   System.Web.UI.Control.EnsureChildControls() +146

Web Part working fine on the top-level page but 'Not Safe' error on lower-level pages.

  
Hi,

I have created a Web Part which reads and parses the SharePoint logs in order to display usage information of the page it resides on.  The Web Part works perfectly on the top page, reading and displaying the information desired.  However, once the Web Part is added to any page lower in the site heirarchy (sub-page) the same Web Part throws the following error:

Error starting SQL Server Agent - Could not load the DLL xpstar90.dll. Reason: 126

  
AD Service account password was changed.  Now the SQL Server Agent (MSSQLSERVER) will not start even after updating the password.  Have no access into the databases.  Log files say "Could not load the DLL xpstar90.dll, or one of the DLLs it references.

Strange: Parser Error: Could not load type '_Default'.

  
i donot have any intentions till now of uploading my web project and just started working on MS VS9.0I made a simple Linq based project (CODE BEHIND used)AS i compiled it i got Parser Error: Could not load type '_Default'.I figured out 2 solutions for this(WHICH I CUDNT FIND IN MANY FORUMS). But nt sure...why doing them solves the problem.SOL 1)The easy way out is to uncheck "place the code in the seperate file" while adding an item.and then adding the statement <%@ Import Namespace="System.Linq" %> on top of ur aspx as in:<%@ Page Language="C#" %><%@ Import Namespace="System.Linq" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">---FURTHER CODE----Sol2)If  we deal whith the CODE behind technique....and have already used "USING System.Linq; in the definition,I found a funny solution to the problem.In ur default page...the top line is<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="<namespace>.<class>" %>Now if i change the keyword from CodeBehind to CodeFile as in:<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="<namespace>.<class>

Error: ASP.NET Ajax client-side framework failed to load.

  
Getting some errors after implementing the calendar control.  Error: ASP.NET Ajax client-side framework failed to load.  Here are some screenshots of the relevant info:   Here's the scenario...  I compile code locally, view the pages in a browser locally, and it all works fine.  Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on my machine), and gets these errors when viewing my locally compiled code.  He then compiles the same code on my machine again just for a test, but still gets the same errors.  Can anyone come up with any good reasons for this behavior?  I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific.  Tried doing that with the same results.  Help!
