I'm using NReco.PdfGenerator for my PDF documents(that component is based on WkHtmlToPdf tool), my code allow me to create a pdf calling a function with the parameters controller, action, model:
public static byte[] GeneratePdfDocument(System.Web.Mvc.Controller controller, string viewName, object model)
{
string result;
controller.ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
result = sw.ToString();
}
return (new NReco.PdfGenerator.HtmlToPdfConverter()).GeneratePdf(result);
}
With this code I can create a PDF easily from my views and it's working great on my development environment but on a server I'm getting this error:
The pipe has been ended.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I think that is maybe a problem with permissions or some configuration on my IIS, any idea?
You are probably missing Visual C++ Redistributable Packages for VS2013 (x86). Even if your server is running 64bit Windows, you need to install the x86 C++ Packages.

I have a MimeMessage which contains a winmail.dat attachment of type application/ms-tnef.
I believe this is an RTF formatted email, which is sent from Outlook client. I tried parsing it with the tnefpart but I'm running into the following error.
Here is my function:
ProcessMimeMessage(MimeMessage plainMime)
{
foreach (var attachment in plainMime.Attachments)
{
if (attachment.GetType() == typeof(MimeKit.Tnef.TnefPart))
{
ReportStatus("Processing Tnef Part (RTF Message): ");
MimeKit.Tnef.TnefPart tnefPart = (MimeKit.Tnef.TnefPart)attachment;
try {
MimeMessage mimeMessage = tnetPart.ConvertToMessage();
} catch (Exception ex) {printexception(ex);}
}
}
}
This is the exception that is thrown from ConvertToMessage
Invalid addr-spec token at offset 0

Thanks
This just means that the "email address" in one of the TNEF fields is not a valid email address (syntactically).
It might just be that the address type field was not "SMTP" and MimeKit tried to parse it as if it were a rfc822 address field.
I've improved the robustness in the following commit: https://github.com/jstedfast/MimeKit/commit/15f955b49dc7743d1281afbedce6d327706e161b
You can use the MyGet packages listed in the README.md file to get the fix for this.
Am getting an error while manipulating Hashes with Servicestack pooled redisClientsManager.
here is how i have registered the IOC
private static IRedisClientsManager redisClientsManager;
redisClientsManager = new PooledRedisClientManager("host:6379");
container.Register<IRedisClientsManager>(c => redisClientsManager);
container.Register(c => c.Resolve<IRedisClientsManager>().GetClient());
container.Register<IRepository>(c => new Repository(c.Resolve<IRedisClientsManager>()));
And Here is how am using it in Repository,
IRedisClientsManager manager;
public repository(IRedisClientsManager mgr)
{
this.manager=mgr;
}
//Method to talk to redis
using(var red = manager.getClient())
{
//do stuff with Other datatype except Hashes WORKS
}
//Error raised here
using(var redHash = manager.getClient())
{
//do stuff with Hashes DOESNT WORKS
}
Error:
Unexpected Error:* 0...., Redis response Error
Any Suggestions on how to use PooledRedisClientManager Threadsafe.!

When you get an Message:Unexpected reply Error when calling a LUA script you need to ensure that what the script is returning matches with the RedisClient API you're calling, which in this case of RedisClient.ExecLuaShaAsString() expects a string.
If you're unsure of what Type your LUA script returns you can call the more reusable ExecLuaSha which returns a complex RedisText type that can support a number of different LUA response types.
I've created a connection using Microsoft Office 12.0 Access Database Engine OLE DB Provider as Excel Schema to loop through all the sheets in the Excel file as demonstrated in this question How to loop through Excel files and load them into a database using SSIS package?
And using Foreach ADO.NET Schema Rowset Enumerator to loop through the excel files.
Everything is working fine now, but after importing the data from Excel, I wanted to move that file to Archive folder. And tried using a File System Task, but I get the error as
[File System Task] Error: An error occurred with the following error message: "The process cannot access the file because it is being used by another process.".
And I also tried with script task from this link. But I was getting some error and couldn't solve the error as I've got zero knowledge on C#.
Below is the error I've got when I tried to move the files using a script task.

Update:
Here's my complete code with which I'm trying to move the files.
If I add a breakpoint at enum ScriptResults, I don't get that popup and the task gets completed successfully and the file is also been moved to archive, but if I don't add any breakpoint in the C# code, I get that pop and the file is not moved to archive.

As far as I understand, I think you have a task for looping through sheets and another for looping through files. So you probably have 2 tasks inside a foreach loop. Try making a copy of the file inside the foreach loop with a system task
for the executable
c:\windows\system32\cmd.exe
and for the arguments soemthing like
C COPY "C:\xxx\abc\\Destination_template.accdb" "C:\xxx\abc\\Destination_template.accdb"Destination_template - Kopie.accdb"
Then create a file system task which moves that copy to your archive.
This should do the trick (Maybe not the best approach but should work)
I have a form that has a DropDownList. I am using SQLServer State mode to save the session in SQL Server. The form is displayed correctly; however, it throws an exception during the form submission. I've been looking and tried some of the suggested answer that were posted online with no luck. What am I doing wrong here?

I think you have too much here. Try changing your code this way
public IEnumerable<SelectListItem> DepartmentList { get; set; }
I usually use List but ienumerable should work too
then on your view you don't need to cast the list
#Html.DropDownListFor(model => model.DepartmentID, Model.DepartmentList, "Select Department", new {#class="form-control", id="DepartmentID", onchange = "ValueSelected()" })
the "for" helper will map the list for you. See if this helps
I created a Word add-in project with a ribbon, and when I want to save the document, after several modifications with OpenXml, an exception is raised.

This problem appears when the document size is larger than 1 MB.
After several searches, the 'save' action is made with an isolated storage, and the solutions is :
Install with Clickonce
Create new domain
Modify registry.
But for this project, I can't use ClickOnce and I can't modify the registry.
So I made changes to my source code, to create a new domain.
Imports DocumentFormat.OpenXml.Packaging
Imports System.IO
<Serializable()> Public Class ToIsolatedPackageSave
Public Sub Save(ByRef mainPart As MainDocumentPart, ByRef xmlDocument As Xml.XmlDocument)
Dim stream As IO.Stream
stream = mainPart.GetStream(FileMode.Create, FileAccess.Write)
xmlDocument.Save(stream) -----> same exception
End Sub
End Class
And
Dim stream As Stream
Dim isolatedPackageSave As ToIsolatedPackageSave
Dim isolatedAppDomain As AppDomain
Try
Dim isolatedAppDomainSetup As AppDomainSetup = New AppDomainSetup()
isolatedAppDomainSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory
Dim isolatedEvidence As Evidence = New Evidence(AppDomain.CurrentDomain.Evidence)
isolatedEvidence.AddAssembly(Reflection.Assembly.GetExecutingAssembly().FullName)
isolatedEvidence.AddHost(New Zone(Security.SecurityZone.MyComputer))
isolatedAppDomain = AppDomain.CreateDomain("TrustIsolatedDomain", isolatedEvidence, isolatedAppDomainSetup)
isolatedPackageSave = isolatedAppDomain.CreateInstanceAndUnwrap(GetType(ToIsolatedPackageSave).Assembly.FullName, GetType(ToIsolatedPackageSave).FullName)
'(IsolatedPackageSave)isolatedAppDomainSetup.CreateInstanceAndUnwrap(GetType(ToIsolatedPackageSave).Assembly.FullName, GetType(ToIsolatedPackageSave).FullName)
isolatedPackageSave.Save(mainPart, MainXMLDoc)
Catch ex As Exception
Finally
AppDomain.Unload(isolatedAppDomain)
End Try
But this code doesn't fix my problem.
I followed Tim Lewis' advice in this post to inject the needed security evidence:
http://rekiwi.blogspot.com/2008/12/unable-to-determine-identity-of-domain.html
public void VerifySecurityEvidenceForIsolatedStorage(Assembly assembly)
{
var isEvidenceFound = true;
var initialAppDomainEvidence = System.Threading.Thread.GetDomain().Evidence;
try
{
// this will fail when the current AppDomain Evidence is instantiated via COM or in PowerShell
using (var usfdAttempt1 = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForDomain())
{
}
}
catch (System.IO.IsolatedStorage.IsolatedStorageException e)
{
isEvidenceFound = false;
}
if (!isEvidenceFound)
{
initialAppDomainEvidence.AddHostEvidence(new Url(assembly.Location));
initialAppDomainEvidence.AddHostEvidence(new Zone(SecurityZone.MyComputer));
var currentAppDomain = Thread.GetDomain();
var securityIdentityField = currentAppDomain.GetType().GetField("_SecurityIdentity", BindingFlags.Instance | BindingFlags.NonPublic);
securityIdentityField.SetValue(currentAppDomain, initialAppDomainEvidence);
var latestAppDomainEvidence = System.Threading.Thread.GetDomain().Evidence; // setting a breakpoint here will let you inspect the current app domain evidence
}
}
Then call the following code at startup:
VerifySecurityEvidenceForIsolatedStorage(this.GetType().Assembly);
I think, you can't use OpenXML inside office addins. If you want to use OpenXML, u have to do it offline (when document is not opened). You can only use COM interops (office object Model calls) from inside addins.
