OpenFile throws 'System.DllNotFoundException'

[mgnslndh]

I call OpenFile on the MoonPdfPanel and get the following exception:

An exception of type 'System.DllNotFoundException' occurred in MoonPdfLib.dll but was not handled in user code

Message

Det gick inte att läsa in DLL-filen libmupdf.dll: Det går inte att hitta den angivna modulen. (Undantag från HRESULT: 0x8007007E)

I am using Nuget package version 0.3.0

Hi,

the problem is that the native libmupdf.dll is not in the executing directory. The NuGet package you are mentioning is not from me, but as far as I can tell, there is no automatism to copy the libmupdf.dll to the output directory. You can find the libmupdf.dll in the lib-folder of the NuGet package, which should be: packages\MoonPdfLib-x86.0.3.0\lib. Include the dll in your project and set its property Copy to Output Directory to Copy Always.

I tried to add dll from the packages folder and i am getting the message or warning from Visual studio

A reference to dll from the package folder could not be added make sure file is accessible and that is a valid assembly or com component

Have you faced the same issue @mgnslndh ?

[reliak]

You can not add the dll in VS because it is a native c-dll. The solution is, as stated above, to use Copy to Output to copy the dll to the executing directory.

@NessfertIndia follow instructions by reliak and it should work.
