Missing assembly problem...

[sub]

What's strange here, is the DLL that he's looking for (DvbtrLib.DLL) is specific to his plugin, and it seems that it is not found in his plugin directory(plugins/DVB-T Radio). For some reason, it tries to find it in another plugin directory (plugins/UKCinema), then in plugins/common.

Yeah, its certainly a bit odd. I'll have a think about it tonight to see if anything comes to me.

Hi sub, Did you have any further thoughts on this?

I fixed my problem by putting the class library in the plugins\common folder as you suggested. This means the gbpvr framework / my plugin DLL happily find it.

Unfortunately, my command-line exe can't find it unless there's also a copy in my main plugin folder. No big deal as this plugin is still experimental but it would be cleaner if everything was in one place.

Cheers,
Brian

I'm at work right now, but I think I can supply you code to put in your exe so that it will find it in the common folder. I'll post this evening when I get home.

I did have an idea, but I didnt get around to investigating it at the time. Unfortunately I'm away from home at the moment, and only have web access so can check for a few days.

sub did implement the plugins\pluginName assembly resolution as well. I've been using it since 1.1.5 came out for my stuff.

So it sounds like you may be able to remove the dlls in the common folder if you don't want them duplicated (and you're on 1.1.5)



EDIT RE-read the posts again, and you can probably disregard my post as insane ramblings....

For your exe, include the following.

When your program attempts to load a DLL, and it is not found, the eventHandler will be called. It will attempt to find the DLL in plugins common, then the GBPVR base directory. If not found, it will display an Error popup message box.

For your exe, include the following.

Thanks - it works a treat.
