Okay, I've been mulling this over and asked on winamp and foobar forums, but still haven't got it working.

Someone on the winamp forum said (the IPC foobar module emulates Winamp IPC calls - apparently) that this should be good:

// WM_WA_IPC 1024
// 150 time to move the trackposition
// 160 IPC_JUMPTOTIME
!SendMessage "Winamp 1.x" "" 1024 150 106

but that doesn't work. Can anyone see any mistakes or ommissions or anything?

Also, the guy who made the foobar IPC plug in said:

result = SendMessage(hwnd_winamp,WM_WA_IPC,(parameter),IPC_*);

So i think you should try

!SendMessage "Winamp v1.x" "" "WM_WA_IPC" "30" "IPC_JUMPTOTIME"

but alas, this isn't working. Can anyone see what's going on here?

I also had a look at other foobar components, one called foo_remote looked like maybe it could help, but it's unsupported on all recentish versions.

devilboi, I had a look at that, wmdman seems to just be for managing windows, and I can't find remote-1.02 anywhere, is it a litestep module? Also I dont think any of those commands sent a command with a parameter, like setvolume x or setposition x. Maybe I should try using spy++ or whatever to get some info on how to access foobar.
