Running VLC in a published visual basic program

Question

0.00/5 (No votes)

See more:

I have created a visual Basic program that keeps track of my 800+ DVD movie collection. I included VLC using AxVLPluginV2. The program runs completely as expected in debug mode, but when I publish the program and run it, I get an error when I try to play the movie.

"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click quit. the application will close immediately.

Could not load file or assembly 'AxInterop.AXVLC, Version=1.0.0.0, Culture, PublicKey or one of its dependencies. The system cannot find the file specified."

As I said earlier, under debug mode it runs fine, and I am able to play a movie with no problems, but when I compile it and publish it so it will run on its own I get the error.

AxInterop.AXVLC.dll is in the MyMovies project directory.

What I have tried:

I don't know what else to try. The program runs fine as it is under debug, but when I compile and publish it, it throws the error. I'm not sure where AxInterop.AXVLC.dll is supposed to be.

Your deployed copy is either missing the AxInterop.AXVLC.dll and/or VLC Player is not installed on the machine either.

The AxInterop dll's are a shim that allows your app to talk to a library. It is NOT a replacement for that library. You still need to deploy the library you're using.

I have since changed to Windows Media Player, Removed all references to VLC, pulled Windows Media Player into the ToolBox, and onto my form, from the COM dialog box and Imported both WMPLib and AxWMPLib to the program. (The editor declared I did not need to import either of these Libraries)compiled and ran it and everything ran as expected. As soon as I published it I got the same error except it said 'AxInterop.WMPLib' I guess I just ASS-U-MEd that being a Microsoft plugin it would include all the necessary files. (silly me), Sooo, how do I assure these libraries get included in the published version?

The Ax???Lib.dll file is generated by Visual Studio when you add a reference to a COM component. You MUST ship this .dll with your application in order for it to work with the COM component.

Also, if you set your reference on a Windows 10 machine with Media Player, chances are good it's not going to work on downlevel machines, like Windows 7. It has a different version of Media Player than 10 does.

How you do that depends entirely on how you're packaging and distributing your application.

Dave;
First, at this time I have no intentions of deploying this to other machines other than my own. It's designed for my movie collection. But, I would like to be able to run it from my task bar without having to load VS and running it there.

So now, that being said, where do I put the .dll files, in the same directory as the .exe or where? Right now they're in the Projects file.

I really appreciate your help on this.

Same folder as the .EXE.
