A problem occurred when executing the sample server code.

not able to launch narrator .exe 64 bit from a 32 bit application

i am trying to launch narrator.exe from my c# code in visual studio but it continuously throws an exception . the code which i am using is
:: " Process NarratorProcess = process.Start(#"C:\Windows\System32\narrator.exe");"
but it continuously throws an exception saying ::
threw exception:
System.ComponentModel.Win32Exception: The system cannot find the file specified
however the file is present in the specified location . I googled and found it may be due to windows file system redirection as in this article System.ComponentModel.Win32Exception when starting process - file not found, but file exists and also followed the steps mentioned there but still it doesnot work. Can someone help me out .

Microsoft.ReportViewer.Webforms "[SerializationException] Member 'ReportServerErrorCode' was not found"

While working on a project to download and attach an Excel render of an SSRS report in a C# project using ReportViewer packages, I encountered the error:
[System.Runtime.Serialization.SerializationException] Member 'ReportServerErrorCode' was not found.
I had encountered it locally and found the fix trivial enough to not write down the solution. Upon deploying the branch to the QA server, I encountered it once more.

The solution is a little complicated. I believe that his error essentially is a one-size-fits all bucket for reporting errors when you don't have the necessary .dlls to get Report Server Error codes. The packages on NuGet have the following .dlls:
Microsoft.ReportViewer.Common
Microsoft.ReportViewer.DataVisualization
Microsoft.ReportViewer.ProcessingObjectModel
Microsoft.ReportViewer.WebForms
In my case this was an error thrown by a dataset. The only way to get to the actual error was to look at the SSRS logs.

String causing a Parse Error that doesn't exist in code

I keep getting the following parse error:
Server Error in '/' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Only Content controls are allowed directly in a content page that contains Content controls.
Source Error:
Line 1: ate
Source File: /admin/JobCategories.aspx Line: 1
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34248
Problem is, the file in question doesn't have that string ("ate") anywhere in it. I did a search in visual studio for it, and found one file containing it.
Strangely enough, the file was shown as JobCategories(1).aspx. I opened it, and tru enough the string was appended to the start of the file. I deleted it, but the error persists, and now when I search for the string in VS I find no results. Tried restarting IIS, rebuilding the website in VS, and restoring an older version of the file from backup that used to work, but I still get the same error.
Only thing done on the file since the last backup was updating a string in the HTML, nothing to do with the code, and nothing near the beginning of the file.
Any ideas? Thanks.

Error in ReportViewer after deploy ClickOnce - HRESULT: 0x80131401

I hope that will help me with this issue.
I have a problem with a application (winforms) build with .net framework 4.5 and ReportViewer 11 (Reporv Viewer 2012). Ago few weeks I deploy using Windows Azure and install to clients, but when i run a report show me an exception.
**An error occurred during local report processing.
Failed to load expression host assembly. Details: Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)**
When I deploy in network (LAN) was working fine, but when I deploy via internet i get this error, this error only occurs when i start the application via shortcut .appref-ms, but if I start application executing .exe file show report correctly.
Some else have this problem and how solve?
Thanks.
