Hello guys ,
I’m an engineer student , I’m doing a little project , I’m new with Labview and I have some a problem that i couldn’t solve after completing my project .Vi I built a .exe the problem is when I test my Vi it works perfectly :

but when I build it to .exe I have a problem 
the error message is

Question

I am using CMO Version 4.0 (which is converted to a .NET assembly) from Copley Controls and LabView to create custom programs to run treadmill amplifiers and create user defined velocity profiles.

I have several versions of similar code, ranging from simple controls to more complicated controls. My standard, base program always works. However, after making a few changes to the more complicated code and saving it as a different file, none of my code works now. I haven’t changing anything to the original, base code and now it doesn’t work.

I keep getting the following error and I do not know what it means:

Error 1172 occurred at Error calling method CMLCOMLib.canOpenObj.Initialize, (System.Reflection,.TargetInvocationException:Exception has been thrown by the target of an invocation. Inner Exception: System.Exception:Access Denied)

I am working on a program I got from a colleague.

I have a simple init vi referencing a constructor in a dll located in the same path as the vi (the path is under c:). I get Error «1172». I have another vi referencing the same dll but now located in another path (still under c:). That works fine. Now that the other dll is in memory init.vi runs fine. I can not explain this behavior!

I also had a similar problem, do you mean you get the error «1172 — System.NullReferenceException»?

I have a VI referencing different constructors of a DLL. All of the constructors work fine except for the most important one, to get the measurements results . Do you mean that if you move the DLL in a different path on C (i have it on a server) it works for you?

When I move the dll to the path (on C) where the calling vi is (init.vi) then I get Error 1172.

For me the error is the following:

Error 1172 occurred at Invoke Node System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
Inner Exception: System.NullReferenceException: The object reference is not set to an instance of an object.

Possible reason (s):

LabVIEW: A .NET exception occurred in an external assembly.

. and only for one funtion I call on the DLL and I call, in the same VI, different functions without errors. Wherever I move the DLL, I cannot make this thing work. I think we have quite similar problem but at least for you it is a small issue as you manage to make the VI working somehow.

I can’t get that far in your example (no idea what domain I should fill in).

What I get from propertyInfo.GetValue, is that object can be null:

object o = propertyInfo.GetValue(myObject, null);

Have you tried to wire a constant to obj? That should be a null object.

In my company I just put our domain name and my user name in domain, but it will not work in your computer. You have to be in domain and try to use your user name. Example:
Domain name: GlobalDomain

User name: dawid.xxx@gmail.com

You cannot leave the obj not connected, you cannot connect constant:( You will get error anyway. I’m really doubt how to deal with it, and where to find a help:(

With constant connected, error msg:
Error 1172 occurred at Invoke Node System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
Inner Exception: System.Reflection.TargetException: Non-static method requires a target.

In stead of GetValue, I’d try GetType. It won’t solve anything directly, but knowing the expected type might get you further. Use ToString to convert the returned type to a readable format.

BTW. UserPrinciple has an EmailAddress propertry. If all you want is the email address, why go through the properties?

Also, I think the object needs to be the object you’re querying about. Could that be the UserPrinciple object?

Yes, That’s the solution. I can get what I need from there:) Thanks. I did not thought about that. So simple:)

Good comment, I think the same, but where to find the answer, what exactly the «GetValue» command needs? You cannot connect reference to obj input.

A lot of the problems with using .NET from LabVIEW come from the fact that C# does them automagically. So the conversion from reference to obj could simply be done by the C# language. Things like this (I thing the entire property construct might be handled under the hood by C#) can make it very hard to find documentation or examples.

I’ve used the C# compiler that is available in .NET to build assemblies to do C# stuff. I don’t like to do it, as it should be possible from LabVIEW, but some things are simply not possible in LabVIEW at the moment. For instance overwriting class members in a child class. That is a pretty normal thing in some corners of .NET.

Hi everyone,

I posted this over in the NI forums as well, but maybe I’ll have more luck over here.

I just ran into an issue this morning after building an executable version of my program, which uses the Actor Framework. It contains a .NET control (version 3.5) on one of my front panels. There’s a function that I call to pass some XML strings to the control, which then handles filling in the data. This works just as expected in the development environment, but when I build an executable and run that, the control just sits there without being properly filled in. I attached an error indicator to the invoke node, which is showing me this error:

Error calling method InstrumentDataGridView.InstrumentDataGridView.LabVIEW_FillTableFromXML, (System.ArgumentNullException: Key cannot be null.Parameter name: key) <append><b>System.ArgumentNullException</b> in Experiment UI.lvlib:Experiment UI Panel.lvclass:Actor Core.vi:1->Actor Framework.lvlib:Actor.lvclass:Actor.vi:4->Actor Framework.lvlib:Actor.lvclass:Actor.vi.ACBRProxyCaller.D140000E

I then ran DebugView to get some more detailed information on what was happening and here’s the log that it spit out:

00000006	80.98936462	[3404] Created new AppDomain: ICAS-EPR.exe for Reflection 	00000007	82.80818939	[3404] Created new AppDomain: ICAS-EPR.exe for Run 	00000008	85.75064087	[3404] DNError: Error calling method InstrumentDataGridView.InstrumentDataGridView.LabVIEW_NotifyAcquisitionStopped (1172).

As you can see, I get a «System.ArgumentNullException: Key cannot be null.» error when calling both LabVIEW_NotifyAcquisitionStopped and LabVIEW_FillTableFromXML. Neither of these functions throw that type of exception. I thought that maybe the constructor wasn’t being called, but I added some code to the constructor to write to a file and that functioned as expected. Then I wrote a new function that wrote to a file and called that when the VI loaded. That function worked fine and didn’t throw any errors. 

I am completely stumped as to why this is happening. Both the development environment and the executable use the exact same DLL code. I appreciate any help I can get!

   HI all,

   I’m encountering an error in labVIEW (2017) when attempting to run this vi: «Kmotion DotNet DLL Sample.vi».
   The error appears to be occurring right after the «KM Controller» constructor node is called.

   The error code is 1172.

   (Error 1172 occurred at Constructor Node Error creating instance of KM_Controller in assembly KMotion_dotNet.KM_Controller, KMotion_dotNet, Version=1.0.1.0, Culture=neutral, PublicKeyToken=fcaf9556d6f68c3a, (KMotion_dotNet.DMException: Dll Not Found Exception thrown : Caller — [KMotion_dotNet.KM_Controller] :: Member — [KM_Controller]))

   Any help would be greatly appreciated!

   Thanks,
   Sean

   Re: KMotion Controller Error
   

   Hi Sean,

   You might try setting the Window’s Environmental Path value to include path to the <>KMotionRelease directory so Labview/Windows/References can find all the necessary libraries. You should probably re-start LabView after changing the variable.

   Regards

	Номер ошибки:	Ошибка 1172
Название ошибки:	.NET Error 1172
Описание ошибки:	Ошибка 1172: Возникла ошибка в приложении .NET Framework. Приложение будет закрыто. Приносим извинения за неудобства.
Разработчик:	Microsoft Corporation
Программное обеспечение:	.NET Framework
Относится к:	Windows XP, Vista, 7, 8, 10, 11

Обзор «.NET Error 1172»

Обычно люди ссылаются на «.NET Error 1172» как на ошибку времени выполнения (ошибку). Разработчики программного обеспечения, такие как Microsoft Corporation, обычно принимают .NET Framework через несколько уровней отладки, чтобы сорвать эти ошибки перед выпуском для общественности. К сожалению, иногда ошибки, такие как ошибка 1172, могут быть пропущены во время этого процесса.

После первоначального выпуска пользователи .NET Framework могут столкнуться с сообщением «.NET Error 1172» во время запуска программы. Во время возникновения ошибки 1172 конечный пользователь может сообщить о проблеме в Microsoft Corporation. Затем Microsoft Corporation нужно будет исправить эти ошибки в главном исходном коде и предоставить модифицированную версию для загрузки. Поэтому, когда вы сталкиваетесь с запросом на обновление .NET Framework, это обычно связано с тем, что это решение для исправления ошибки 1172 и других ошибок.

Что вызывает ошибку времени выполнения 1172?

«.NET Error 1172» чаще всего может возникать при загрузке .NET Framework. Вот три наиболее заметные причины ошибки ошибки 1172 во время выполнения происходят:

Ошибка 1172 Crash — Номер ошибки вызовет блокировка системы компьютера, препятствуя использованию программы. Если данный ввод недействителен или не соответствует ожидаемому формату, .NET Framework (или OS) завершается неудачей.

Утечка памяти «.NET Error 1172» — ошибка 1172 утечка памяти приводит к тому, что .NET Framework постоянно использует все больше и больше памяти, увяская систему. Возможные провокации включают отсутствие девыделения памяти и ссылку на плохой код, такой как бесконечные циклы.

Error 1172 Logic Error — Ошибка программной логики возникает, когда, несмотря на точный ввод от пользователя, производится неверный вывод. Это происходит, когда исходный код Microsoft Corporation вызывает недостаток в обработке информации.

.NET Error 1172 проблемы часто являются результатом отсутствия, удаления или случайного перемещения файла из исходного места установки .NET Framework. Как правило, решить проблему позволяет получение новой копии файла Microsoft Corporation, которая не содержит вирусов. Помимо прочего, в качестве общей меры по профилактике и очистке мы рекомендуем использовать очиститель реестра для очистки любых недопустимых записей файлов, расширений файлов Microsoft Corporation или разделов реестра, что позволит предотвратить появление связанных с ними сообщений об ошибках.

Классические проблемы .NET Error 1172

Эти проблемы .NET Framework, связанные с .NET Error 1172, включают в себя:

• «Ошибка в приложении: .NET Error 1172»

• «Проблема при запуске приложения: .NET Error 1172. «
• «Не удается запустить .NET Error 1172. «
• «.NET Error 1172 выйти. «
• «Ошибка пути программного обеспечения: .NET Error 1172. «

Проблемы .NET Error 1172 с участием .NET Frameworks возникают во время установки, при запуске или завершении работы программного обеспечения, связанного с .NET Error 1172, или во время процесса установки Windows. Выделение при возникновении ошибок .NET Error 1172 имеет первостепенное значение для поиска причины проблем .NET Framework и сообщения о них вMicrosoft Corporation за помощью.

Эпицентры .NET Error 1172 Головные боли

Эти проблемы .NET Error 1172 создаются отсутствующими или поврежденными файлами .NET Error 1172, недопустимыми записями реестра .NET Framework или вредоносным программным обеспечением.

В первую очередь, проблемы .NET Error 1172 создаются:
