WPF app not exiting because of UWP PdfDocument - c#

I'm trying to use the UWP Windows.Data.Pdf API from a WPF-Desktop app. It can render a PDF page to a PNG image just fine.
The issue I have is that after executing the PDF rendering, closing the WPF-Window does no longer exit the application. The process keeps running. I tried pausing the application in the debugger in this state, but no application code appears to be running. Some thread or resource must still be open, I guess.
My question here is does anybody have any idea why this happens? And furthermore, how can I debug this kind of issue?
The issue is reproducible with the empty WPF template in VS17, I added to the .csproj:
<TargetPlatformVersion>10.0.16299.0</TargetPlatformVersion>
...

</Reference>
<Reference Include="Windows">
<HintPath>$(MSBuildProgramFiles32)\Windows Kits\10\UnionMetadata\10.0.16299.0\Windows.winmd</HintPath>
</Reference>
From a simple button I'm executing this code:
using System;
using System.Runtime.InteropServices.WindowsRuntime;
using System.Threading.Tasks;
using Windows.Data.Pdf;
using Windows.Graphics.Imaging;
using Windows.Storage;
using Windows.Storage.Streams;
...
var filename = #"C:\Users\...\a.pdf"
var f = await StorageFile.GetFileFromPathAsync(filename);
byte[] content;
using (var stream = await f.OpenReadAsync())
{
var d = await PdfDocument.LoadFromStreamAsync(stream);
using (var page0 = d.GetPage(0))
{
await page0.PreparePageAsync();
using (var randomAccessStream = new InMemoryRandomAccessStream())
{
await page0.RenderToStreamAsync(randomAccessStream, new PdfPageRenderOptions { BitmapEncoderId = BitmapEncoder.PngEncoderId });
content = new byte[randomAccessStream.Size];
await randomAccessStream.ReadAsync(content.AsBuffer(), (uint)randomAccessStream.Size, InputStreamOptions.None);
}
}
}
File.WriteAllBytes(#"C:\Users\...\b.png", content);
This is almost the entire code, but in case I missed something I also pushed it to https://github.com/marv51/PDFRendererNotExiting
Thank you very much in advance for any help on this.
Update:
I just observed, that the process does eventually exit after about 2 minutes!
Probably related, I found in the event viewer:

So I assume some background thread crashed during termination and Windows Error Reporting keeps the process alive to collect information. Or some kind of timeout kills open resources?
I'm sorry, I just found this. Can I do anything with this crash Information?
Update 2
After spending a lot of time on this and learning some windbg, I think this might be an Nvidia graphics driver crash:
Attaching to the app and then closing the window shows this exception:
(2134.1cac): Unknown exception - code 0000071a (first chance)
(2134.1cac): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

I posted the analyze -v output here: https://gist.github.com/Marv51/d3ad0e9a49b6c985d9116600fd0475b7
From looking at the stacktrace I believe the destructor for the internal class Windows.Data.Pdf.CPdfStatics tries to release some DirectX resources and the Nvidia driver corrupts the heap during this process.
I tried updating to the latest Nvidia driver, which changed nothing.
Not sure where I can go from here. I'm still a windbg beginner, so I might interpret this output wrong.
Maybe the 'solution' for now is that I will do this work in an external process to avoid these issues from 'infecting' the main app.

Windows Forms - How can I prevent a System.AccessViolationException when opening a new thread

I am hoping this issue is an obvious one to someone šŸ˜Š I have a Windows Forms application that does some independent processes on separate sub-forms. It has a MainForm that opens first and then it opens the sub-forms based on an ā€œis activeā€ database value for each sub-form. This process runs as expected often for many hours without any issuesā€¦ opening and closing when necessary. The issue that I am having trouble figuring out is one where the application just freezes and has to be manually closed and restarted which of course while it isnā€™t running stops processing altogether.
There are always 2 errors in the Windows Application error log. First is a ā€œ.Net Runtimeā€ and the second is a ā€œApplication Errorā€. There is a third Information entry that appears to be logged when the application is restarted but not 100% certain if it is present before it is restarted.
The MainForm is opening the different sub-forms in a new thread using different versions of this:
try
{
Thread CS = new Thread(new ThreadStart(CS_Start));
CS.SetApartmentState(ApartmentState.STA);
CS.Start();
}
catch { }
And this is the code it is called in the new thread which is opens one of the sub-formsā€¦
private void CS_Start ()
{
try
{
using (CS_Searches CS_SearchForm = new CS_Searches())
{
if (!CS_SearchForm.Visible)
CS_SearchForm.ShowDialog();
}
}
catch { }
}
There are 5 separate forms that the MainForm opens. Each form does completely separate tasks and will also close itself based on the ā€œis activeā€ value using: this.Dispose();
The issue seems to always occur at the different CS.Start(); lines. I have tried catching the error but unfortunately it never hits this code. Iā€™ve also modified the CS_Start by adding the using statement. Unfortunately I havenā€™t been able to replicate the issue as it runs great until it doesnā€™t and the frequency can be all over the map. Based on all my Googling it appears to be a memory access violation but I am having no luck confirming this or finding a fix. Any assistance would be greatly appreciated.
Thanks,
Greg

This is really interesting to explore - you may go with making dumps and exploring them with WInDbg. But I would consider creating the same application as Console Application and exploring its behavior. It may turn out it was some kind GUI related bug/feature where you reached maybe Handlers/GDI limit or something like this.

App crashes at startup, KERNELBASE.dll, Exception Code e0434352

My C# / WinForms app crashes at startup.
I went through several posts here that cover that topic but I wasn't able to solve the problem yet.
That is the error I get:

However, that doesn't really help me. I've checked the startup of the app in debug mode (different machine) where I am able to run it and logged the loaded assemblies. I went over each assembly and checked whether it was available on the other machine. Everything was there, although some assemblies are not available in the GAC but in the apps directory.
I have no idea where to look now, thanks for your help!
Edit: I get this message in the event viewer:
Anwendung: MyApp.exe
Frameworkversion: v4.0.30319
Beschreibung: Der Prozess wurde aufgrund einer unbehandelten Ausnahme beendet.
Ausnahmeinformationen: System.IO.FileLoadException

Is there a way to get more information which assembly is missing?

I solved my issue by checking the versions of the referenced assembly. One third-party assembly had a minor update which I forgot to update in my clients folder.

Exception when StreamInsight 2.3 is running

I have StreamInsight client:
var quoteStreamable = application.GetStreamable<IntradayQuote>(symbol);
var matchQuery = from quote in quoteStreamable.ToObservable()
where quote.Symbol == symbol
select new MatchPairs
{
Quote = quote,
Order = order
};
var sink =
application.GetObserver<MatchPairs>(StreamInsightConfiguration.Default.StreamInsightServerSinkName);
var clientProcessName = WindowsServiceUtility.InitClientProcessName(order.Id, symbol);
if (!application.Entities.ContainsKey(clientProcessName))
{
using (matchQuery.Bind(sink).Run(clientProcessName))
{
.....
}
}
I have 100 clients. When I run 100 clients, the StreamInsight will be crashed.

How to fix this problem ? or let me know what is the reason about above exception ?

Stopping IIS Application Pool c#

I am trying to stop a remote system's IIS application pool using the following c# code:
try
{
// Assign a variable to store the Connection Options
var connection = new ConnectionOptions();
// Connect as this user
connection.Username = Globals.AdminUsername;
// Connect with this password
connection.Password = Globals.AdminPassword;
// Connect using this domain
connection.Authority = "ntlmdomain:MyDomain";
// Gets or sets a value indicating whether user privileges
// need to be enabled for the connection operation.
connection.EnablePrivileges = true;
// Enable impersonation so non admins can run admin level commands
connection.Impersonation = ImpersonationLevel.Impersonate;
//Each data packet is signed and encrypted. This helps protect
// the entire communication between the client and server.
connection.Authentication = AuthenticationLevel.PacketPrivacy;
// Define a WMI management scope
var wmiScope = new ManagementScope(String.Format("\\\\{0}\\root\\MicrosoftIISv2", ServerName), connection);
string objPath = "IISApplicationPool.Name='W3SVC/AppPools/" + AppPoolName + "'";
// Run the query using the scope defined above
using (ManagementObject AppPool = new ManagementObject(wmiScope,new ManagementPath(objPath), null))
{
switch (Action)
{
case "Start":
AppPool.InvokeMethod("Start", null, null);
break;
case "Stop":
AppPool.InvokeMethod("Stop", null, null);
break;
case "Recycle":
AppPool.InvokeMethod("Recycle", null, null);
break;
}
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.ToString());
}
If I stop my application pool it works, but I get a bunch of errors on the server:
-----
The root\MicrosoftIISv2 namespace is marked with the RequiresEncryption flag.
Access to this namespace might be denied if the script or application does not have the
appropriate authentication level. Change the authentication level to Pkt_Privacy
and run the script or application again.

I'm pretty sure that I shouldn't be getting these errors because if I manually (vs programmatically) start/stop the application pool I don't get these warnings or errors.
Can anyone help me understand why I'm getting these errors. I am setting Packet_Privacy I think so that warning doesn't make sense to me.
Thanks

Firefox crash when I run selenium unit test

I start use Selenium.WebDriver (v2.45) to run visual tests.
As web driver I use FirefoxDriver. I have installed Firefox 38. When I try run test firefox return exception with message:
FF has stopped working.
Does anyone have any suggestions? It worked in previous week, is it possible that my test was crashed by updated?
Problem signature:
Problem Event Name: APPCRASH

There is my test method body:
[Fact]
public void ShouldLoginForTestAccount()
{
var driver = new FirefoxDriver();
driver.Manage().Cookies.DeleteAllCookies();
driver.Navigate().GoToUrl(LoginPage);
driver.FindElementById("Login")
.SendKeys("correctLogin");
driver.FindElementById("Password")
.SendKeys("correctPassword");
driver.FindElementByTagName("button")
.Click();
Assert.Equal(TestingProjectUrl, driver.Url);
driver.Close();
}

Selenium 2.45 does not reliably work with Firefox 38 due to compatibility issues.
Downgrade Firefox to 35 (link to 35.0.1).

I have a suggestion.
I was getting the error bellow when I called Quit() method of WebDriver.
unknown software exception (0x80000003) em 0x55fdec79
So I created the WebDriver as follow:
FirefoxOptions foxOptions = new FirefoxOptions();
foxOptions.SetPreference("dom.allow_scripts_to_close_windows", true);
driver = new ThreadLocal<IWebDriver>(() => { return new FirefoxDriver(service as FirefoxDriverService, foxOptions, new TimeSpan(0, 1, 0)); }).Value;
Then, before call Quit() method, I execute one javascript to close the main window:
try { ((IJavaScriptExecutor)driver).ExecuteScript("window.close();"); } catch { }
So now I'm able to call Quit() without get any error. I know that this is a workaround, but I think this can help you.
