I'm building a project in Visual Studio 2012. When I press F5 to run the app, it works just fine, however when I load it up in IIS7 on my Windows Pro box, the first time I make a call to a specific code base, I get the following error.
The thread 'Win32 Thread' (0x4d8) has exited with code 0 (0x0).
Unhandled exception at 0x7797e6c3 in w3wp.exe: 0xC0000374: A heap has been corrupted.
First-chance exception at 0x778e32a0 in w3wp.exe: 0xC0000005: Access violation reading location 0x2039a9f2.
Unhandled exception at 0x778e32a0 in w3wp.exe: 0xC0000005: Access violation reading location 0x2039a9f2.
Now I've attached the w3wp.exe to the VS2012 debugger, but to be honest, I'm not sure how to debug this type of crash.
For reference, the code base that's being called in a WebAPI controller that makes a call to the ActiveHome SDK to control some automation bits.
// GET api/<controller>/5
public StatusModel Post(CommandModel command)
{
var activeHome = new ActiveHomeClass();
// execute command
var info = activeHome.SendAction(command.SendAction, String.Format("{0} {1}", command.Device, command.Command));
// return results
var status = new StatusModel { Device = command.Device, Status = info };
activeHome = null;
return status;
}
Note: I am compiling everything to use x86

I try to receive user's PushNotification Channel URI (Windows 10 platform) and for some users application generate exception This operation returned because the timeout.
To handle errors in a task chain I should add a task-based continuation at the end of the chain and handle all errors there (as explained here https://learn.microsoft.com/en-us/windows/uwp/threading-async/asynchronous-programming-in-cpp-universal-windows-platform-apps#handling-errors-in-a-task-chain).
So I did that. But after I call t.get(); system generate Platform::COMException^ exception by it not catch in try-catch block. Why?
There is the code:
{
create_task(PushNotificationChannelManager::CreatePushNotificationChannelForApplicationAsync())
.then([this](PushNotificationChannel^ pnChannel)
{
// ..
// DONE: pnChannel->Uri
// ..
}, task_continuation_context::get_current_winrt_context())
.then([](task<void> t)
{
try
{
t.get(); // <<<< After exec this line app crash!
}
catch (Platform::COMException^ e)
{
OutputDebugString(L"Exception catches!");
}
});
}
There is the full exception message:
Exception thrown at 0x00007FFD9D74A388 in GameName.exe: Microsoft C++
exception: Platform::COMException ^ at memory location 0x000000249A9FEB60.
HRESULT:0x800705B4 This operation returned because the timeout period expired.
WinRT information: This operation returned because the timeout
And Visual Studio throws me to the file c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\exception to block:
[[noreturn]] void _RethrowException() const
{
__ExceptionPtrRethrow(this); // <<<< here everything stoped!
}
UPDATED:
Enviroment:
Visual Studio 2017 (15.7.3)
Project based on cocos2d-x (3.16)
Project Targe Platform Version = 10.0.1493.0
Project Platform Toolset = Visual Studio 2015 (v140)
You can clone cocos2dx project and in MainScene paste code I showed before in onEnter method (or anywhere).
I got a situation when I had crash 100% for me
Uninstall app if it was built before;
Disconnect from the internet;
Build app & launch;
The app will try to detect Channel URI & will crash (but with crash message = WinRT information: The network is not present or not started).
I understand that throwing that exception is normal. But I still cannot understand why when I call t.get() it not catch exception Platform::COMException^
I have the following code inside my asp.net mvc web application to retrieve the Active directory user names:-
public List<DomainContext> GetADUsers(string term=null)
{
List<DomainContext> results = new List<DomainContext>();
using (var context = new PrincipalContext(ContextType.Domain, "v800047"))
using (var searcher = new PrincipalSearcher(new UserPrincipal(context)))
{
the above was working well on our development environment, but when i moved my code to the staging server and i changed the AdServerName accordingly , i am getting the following error :-
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 have developed ASP.net application using VS-2010, C#.Net 4.0 with SharpSvn dll. When I'm working with dev server(don't have 3-Tier Architecture), it works fine. But when we are working with QA environment(have 3-Tier Architecture) it gives thread abort exception most of the time.Following shows the code and error log I have. Any help on this really appreciate.

{
Log.Info("Successfully checked out to following location : " );
Log.Info(target);

I missed <httpRuntime executionTimeout="(time in seconds)">
tag in web config and it automatically set by IIS server. The default is 110 seconds.
Note :In the .NET Framework 1.0 and 1.1, the default is 90 seconds.
After I added following line to web.config and it works fine.
<httpRuntime executionTimeout="600">
Previously it works sometimes because the time taken to SVN checkout in DEV server is less than in other environment because of the size of the repositories and network connections. Thanks all for your answers
As per my comment above, I've seen this issue. It appears to be related to plink authentication.
I resolved it by upgrading to the latest build of SharpSVN v1.7, at which point the error changed from a null-ref exception in the C++, to an SVN exception with the message "Can't create tunnel: The parameter is incorrect".
There are a few articles which explain how to resolve this, the best of which I've found here:
SVN+SSH and Sourceforge
In my case, changing the backslashes to forwardslashes in the SVN_SSH env var resolved the problem. Worth giving a shot.
Am facing a problem, while creating components through TOM API using .NET/COM Interop.
Actual Issue:
I have 550 components to be created through custom page. I am able to create between 400 - 470 components but after that it is getting failed and through an error message saying that
Error: Thread was being aborted.
Any idea / suggestion, why it is getting failed?
OR
Is there any restriction on Tridion 2009?
UPDATE 1:
As per #user978511 request, below is error on Application event log:-
Event code: 3001
Event message: The request has been aborted.
...
...
Process information:
Process ID: 1016
Process name: w3wp.exe
Account name: NT AUTHORITY\NETWORK SERVICE
Exception information:
Exception type: HttpException
Exception message: Request timed out.
...
...
...
UPDATE 2:
#Chris: This is my common function, which is called in a loop by passing list of params. Here am using Interop dll's.
public static bool CreateFareComponent(.... list of params ...)
{
TDSE mTDSE = null;
Folder mFolder = null;
Component mComponent = null;
bool flag = false;
try
{
mTDSE = TDSEInitialize();
mComponent = (Component)mTDSE.GetNewObject(ItemType.ItemTypeComponent, folderID, null);
mComponent.Schema = (Schema)mTDSE.GetObject(constants.SCHEMA_ID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadAll);
mComponent.Title = compTitle;
...
...
...
...
mComponent.Save(true);
flag = true;
}
catch (Exception ex)
{
CustomLogger.Error(String.Format("Logged User: {0} \r\n Error: {1}", GetRemoteUser(), ex.Message));
}
return flag;
}
Thanks in advance.
Sounds like a timeout, most likely in IIS which is hosting your custom page.
Are you creating them all in one synchronous request? Because that is indeed likely to time out.
You could instead create them in batches - or make sure your operations are done asynchronously and then polling the status regularly.
The easiest would just be to only create say 10 Components in one request, wait for it to finish, and then create another 10 (perhaps with a nice progress bar? :))
How you call TDSE object. I would like to mention here "Marshal.ReleaseComObject" procedure. Without releasing COMs objects can lead to enormous memory leaks.
Here is code for component creating:
private Component NewComponent(string componentName, string publicationID, string parentID, string schemaID)
{
Publication publication = (Publication)mTdse.GetObject(publicationID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadContext);
Folder folder = (Folder)mTdse.GetObject(parentID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadContext);
Schema schema = (Schema)mTdse.GetObject(schemaID, EnumOpenMode.OpenModeView, publicationID, XMLReadFilter.XMLReadContext);
Component component = (Component)mTdse.GetNewObject(ItemType.ItemTypeComponent, folder, publication);
component.Title = componentName;
component.Schema = schema;
return component;
}
After that please not forget to release mTdse ( in my case it is previously created TDSE object). Disposing "Components" object can be useful also after finish working with them.
For large Tridion batch operations I always use a Console Application and run it directly on the server.
Use Console.WriteLine to write to the output window and Console.ReadLine as the last line of code in the app (so the window stays open). I also use Log4Net as the logger.
This is by far the best approach if you have access to a remote session on the server - or can ask an admin to run it for you and give you access to the log folder via a network share.
As per #chris suggestions and part of immediate fix I have changed my web.config execution time out to 8000 seconds.
<httpRuntime executionTimeout="8000"/>
With this change, custom page is able to handle as of now.
Any more best suggestion, please post it.
I am trying to call a service from a silverlight application, but I am getting the following error.
Uncaught Error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
This works fine locally. I don't know if it make any sense, but locally if I add the url of the webservice on a browser, I am getting the details page of the service. In the other hand, on production server, it prompts me to download it.
Does anyone know something about this?
Thanks
public MainPage() {
InitializeComponent();
Loaded += new System.Windows.RoutedEventHandler(MainPage_Loaded);
}
private void MainPage_Loaded(object sender, System.Windows.RoutedEventArgs e) {

newsFeedWcfClient.GetNewsFeedItemsCompleted += newsFeedWcfClient_GetNewsFeedItemsCompleted;

var source = (IList<NewsFeed>)e.Result;
IList<CustomNewsFeed> customNewsFeeds = new List<CustomNewsFeed>();
foreach (var item in source) {
customNewsFeeds.Add(new CustomNewsFeed() {
ProductID = item.Products.ProductID,
ProductTitle = item.Products.Title,
Status = item.Text,
Thumb = string.Format("{0}/{1}", item.Products.Product_Photos.Select(pp => pp.PhotoPath).FirstOrDefault(), item.Products.Product_Photos.Select(pp => pp.PhotoName).FirstOrDefault()),

});
}
NewsFeedLB.ItemsSource = customNewsFeeds;
}
The fact that on the production server it "prompts you to download" would suggest that the production web server doesn't know what to do with your .svc or .asmx file. It is treating it like a normal file (.txt, .pdf etc).
Have you got all of the required items installed in production. For instance, you need the correct .NET runtime to be installed. Also, ASP.NET needs to be installed and then enabled.
To determine exactly what is happening I would recommend installing Fiddler and using it to trace what is happening when the Silverlight app calls the server. I have found this approach to be invaluable when troubleshooting Silverlight to Web Service communication problems.
