Sometimes this program causes the ntdll.dll to behave strangely and makes our explorer.exe and our mmc.exe to crash.

We don't have any idea's where to go look, let alone resolve our problem.

Underneath you will find the Debug report for when mmc.exe crashed.

Excuse me, but what's the use? You gave as the debug report without the code sample...
—SA

Nomardus 31-May-13 5:45am

Uploaded the code as requested ;)

Sergey Alexandrovich Kryukov 31-May-13 8:08am

Oh... could you also indicate the line where the exception is thrown? This is important.

From the first glance, the code has problems, such as pretty severe lack of reuse and too local handling of exceptions. You could get rid of local handling of exceptions (at lest for debugging time), which is easy, and catch all exceptions up the stack (a must anyway). If forms, it should be done in a special handler of the main event loop:

http://www.codeproject.com/Answers/237363/Error-Logging-and-Screen-Shot#answer2
http://www.codeproject.com/Answers/139319/Catching-an-Exception#answer2

Then you would be able to see the exception's propagation path...

Is that clear?

—SA

Nomardus 31-May-13 8:23am

Well, I have no idea which line this is, since it doesn't ahppen when we are debugging, it only happens when we run the exe.

Sergey Alexandrovich Kryukov 31-May-13 8:29am

Above, I actually just explained how to find it out. Oh, yes, you also should enable debugging information (compile predefined Debug configuration) and output Exception.StackTrace. This is just a string, but it will show the whole path of propagation of an exception from the point of throwing to the point of catch, with line numbers... Then you can find ends. How about that?

Looks like you're using PerfMon or some P/Invoke?? Am I right?? If yes, then start with adding a small description of your Application and what it tries to do... we'll be able to help you better.

Nomardus 31-May-13 2:52am

The program is designed to get .txt files from our shared drive and read them in to the textbox of the program.
We load in a list of .txt files from which we can choose in multiple languages. Once we have the correct .txt file, we copy this to the clipboard and paste it into an other program (Remedy). An other question, I would like to upload the code in a zip-file, but can find the upload function, any possible way to do this?

AlphaDeltaTheta 31-May-13 5:31am

That should not be an issue... did you test with a local copy?? And in your code, I don't see any p/invoke may be some problem beyond our control (in the code)... Is the shared drive connected properly??
Sorry, i'm unaware of any such file-upload facilities of CP, we generally upload our zip to a file-sharing site and post the link here eg. Dropbox/Box/Google drive public share

Nomardus 31-May-13 5:45am

The shared drive is properly connected, we use it for many other things as well.
We made a local copy to our desktop, but still had the same issue.
That is why we are out of idea's.

AlphaDeltaTheta 31-May-13 6:58am

So am I... I can't imagine any link with explorer.exe , mmc and mostly ntdll.dll, which handles kernel-mode operations... certainly this isn't a driver?? !!

AlphaDeltaTheta 31-May-13 7:03am

Why do you use Convert.ToChar(92) you could use a backslash instead or a verbatim string like


 string directory = @"\\bemech002m\BemechData2\ITSB\Service_Desk\_Remedy Email Reply Scripts\Remedy Scripts Central";

AlphaDeltaTheta 31-May-13 7:06am

I can't get anything from this code... may be anywhere else... if you can upload then upload the entire zip into Dropbox, share and post the link

Nomardus 3-Jun-13 8:50am

Sorry for the late reply, but I didn't have the project on my home pc and work pc doesn't allow dropbox.
But here is the link to the entire project. https://www.dropbox.com/s/yesk3enlekfhzqd/Project_Valkyri.zip

I scanned your code, built it, ran it... no issues, a window appeared saying template folder issue? Is that what you intend? you can see a screenshot here. And through your code, I did not find anything suspicious or anything that was likely to crash ntdll.dll, core level windows dll. Except for Sendkeys.SendWait(), that's the only call to a native dll here. Check that.

Yes that is normal, we create normally a couple of folders to show, but those weren't included in the zip file.

Seems like we found what was wrong.
We had to many Clipboard.clear(); in the program and the computers just couldn't handle it anymore.
We took them out and we are now running it without problems for 2 days.
