We made a DLL to be used with a C# application. The DLL has be created with a dependency (.MAT file) that is attached with the DLL. On particular instance, the mat file is load during the function call. However, in some instance, we got errors which as per our error handling (Try catch statements) reveal that it was unable to load the MAT file. 

How can we make the call more robust? How to prevent such issues? We do not want to disclose the content of the MAT file. Please advice.

I meant you can put in a permanent directory, perhaps C:\install\abc.mat. You can then load it from the fixed location easily.

If you wish to debug, you can print out "pwd" in the log to see which folder the dll is taking as working directory. It maybe the same directory as the location of dll file. In that case you can place the mat file in the same location as the dll file.

Thats a great idea. But I do not want to reveal the information in the mat file. If there is way to encrypt ... if yes, then I can provide a static path.
