How to write a plug-in for MC12?
« on: April 10, 2007, 06:23:36 pm »

I spent the evening writing some plugin stuff for a friend and ended up with working code, but being very confused by it all...  I think the wiki is rather mis-leading, or more likely, I'm working on one object while typing it as another.  Unfortunately, everyone's just put snippets of code rather than a whole example.

Anyway, main questions...

1/ What is the type of the object I get from CreateObject("MediaJukeBox Application") ?  I've been using it as an MCAutomation, but that appears to diverge from the SDK a lot, most annoyingly in the GetCurPlaylist automation area.

2/ If I'm controlling MediaCenter, should I be attaching to mediajukebox ?  I'm a bit confused by the object naming here!

Help appreciated :)  I'd update the wiki with my findings, but they're so confused that it would be even more disorientating!

Hmm, some of my problems were actually my usual Sub Vs. function Vs. () vs. not in VB (I hate VB6), however, some of the docs are still a bit wrong..

My current object creation code is (incidentally, all examples could do with being replaced with this, on error resume next is 'orrible):

Quote

Private WithEvents MC As MCAutomation

Private Function ErrFunction() As Integer
    Select Case Err.Number
        Case 462
            Set MC = CreateObject("MediaJukebox Application")
            ErrFunction = 1
        Case 429
            Set MC = CreateObject("MediaJukebox Application")
            ErrFunction = 1
        Case Else
            MsgBox (Err.Description)
            ErrFunction = 0
    End Select
End Function

Private Sub Form_Load()
    On Error GoTo ErrHandler
   
    Set MC = GetObject(, "MediaJukebox Application")
   
    szCurrentScheme = ""
    intCurrentPlaylist = 0
    txtScheme.Text = MC.GetViewScheme(szCurrentScheme).GetScheme(0).GetName()
   
Exit Sub
ErrHandler:
    If ErrFunction Then
        Resume Next
    Else
        End
    End If
End Sub


The docs (paraphrasing) prototype as follows
Quote
void MJFilesAutomation.Play()

it is actually:

Quote
void MJFilesAutomation.Play(number Position)

I guess the current docs are just inaccurate in places...?
