AdiIRC

I created a thread about it in the WACUP-community: https://getwacup.com/community/index.php?topic=1195.0

The m3u file is only searched if the proper plugins are installed and winamp is set as the current media player and winamp is running. There is one plugin for adiirc and one for winamp, Interop.ActiveWinamp.dll for adiirc and gen_activewa.dll for winamp.

the gen_activewa.dll must be registered with the regsvr32 command, AdiIRC tries to install and set all of this up when you change media player to winamp. It uses the path for winamp set in Options -> Media player to put the plugin in the correct place, but it can be a little buggy since winamp has to be closed etc.

The plugin might not work on this fork, if necessary it can be downloaded here https://adiirc.com/gen_activewa.dll and the adiirc plugin here https://adiirc.com/Interop.ActiveWinamp.dll.

Note: gen_activewa.dll was made by someone else not related to AdiIRC.

Another quick note, the adiirc winamp plugin is not a plugin you will find in Menubar -> File -> Plugins, it just needs to be in the config folder and AdiIRC will automatically use it when necessary, the problems are usually with gen_activewa.dll which needs to be in winamppath\plugins\genactivewa.dll and registered in that path with regsvr32.exe.

Got curious, installed WACUP, my m3u file was called winamp.m3u8, everything seems to work fine including searching from the ctrl + j dialog.

Everything is working fine on my side now; I simply disabled the plugin and re-enabled it by switching over to Winamp again and then it worked!

Wasn't a problem of AdiIRC or WACUP after all, so can be closed.
