Labview Error Code 1172

Why am I getting Error 1172 when trying to invoke .NET assembly? But what I don't understand is why the file can't be found (Le fichier spécifié est introuvable) since all the .DLLs that are needed are in the same directory.

I made a new project, with one new class inside. I attached a Word document that I received from the engineer in China that describes the problem. I'll forward your comments to both teams (in Mexico and China) and if they have any questions or comments in response, I will post them here. You'll always destroy the notifier after the first while loop iteration, which means the second iteration will always return an error, so why have the while loop?

Unless you're trying to access static methods or properties, you have to instantiate the object with the constructor node before any object exists that has any methods or properties. That test passed at the development site in Mexico.

So the first question to me would be, how was this DLL even tested? But I think it looks messy. delete the numbers uniq -c created Method to replace inefficient building of lists using searchcursor Expression must be a list type: Set Is space piracy orbitally practical? You have to look at the source string (which is shown in the dialog) to see the actual details of where the problem was, and you can see here that it

Neither of these functions throw that type of exception. http://ascadys.net/labview-error/labview-error-code-3.html That function worked fine and didn't throw any errors.    I am completely stumped as to why this is happening.

A software engineer in Mexico wrote a DLL in C# that LabView calls, then the DLL sends commands to perform some of the tests.

I have referenced the .dll but when I try to increase assembly trust it says "Unable to load assembly" .... http://ascadys.net/labview-error/labview-error-1172.html Tst, I have added the logging on the LabVIEW side with the"+.NET Error Info" VI.

Only if you want to bypass your Mexican DLL.

The typical message you will see is similar to: 1172, kLVE_DotNetException, A .NET exception occurred.
In LabVIEW 8.0, more information was added to the Now I get the error 1172.

The C# programmer tested the DLL pretty thoroughly, including downloading LabView 2011 and making sure LabView could call the DLL. I'm a product development manager in California. Lastly, when using the constructor node, if you change the selected file by one of the same name (example:Me comparing all the ILAS.Headless.dlls I had) LabVIEW does not update the functions What could make this crash after 20+ Hours?

If they are on my local hard drive there is no problem.

I have also created a VI that runs this command with a loop rate of 30 mS Currently, I have made a new EXE with the aforementioned changes
