StarBurnX OnProgress

I'm having problems getting OnProgress going. So I have a few questions that should help me resolve this.
1/ How is it created?
a/ objAudioBurner > Drive > OnProgress
b/ objAudioBurner > OnProgress
c/ Another way

2/ If I attach a variable to it like: "Progress = objAudioBurner.OnProgress", does that create a new object?

3/ If it is a new object is it sending 'dispatch' type events and are the events being sent as 'by reference'.

Thanks.

Hello,

1) At the first it is not clear what programming language do you use?

2) For the C#:

Code:

 private void InitializeAudioBurner()
 {
     // Creates new AudioBurner  - once
     m_audioBurner=  new AudioBurnerClass();

    // Attach Event handlers
    m_audioBurner.OnProgress    += new IAudioBurnerEvents_OnProgressEventHandler(this.OnProgress);

    m_audioBurner.OnBuffer      += new IAudioBurnerEvents_OnBufferEventHandler  (this.OnBurningBuffer);    

    m_audioBurner.OnTestWriteDisabled +=new IAudioBurnerEvents_OnTestWriteDisabledEventHandler
(OnTestWriteDisabled);
}

Code:

private void UninitializeAudioBurner()
{
      if(m_audioBurner != null)
      {
           m_audioBurner.OnProgress    -= new IAudioBurnerEvents_OnProgressEventHandler(this.OnProgress);
           m_audioBurner.OnBuffer      -= new IAudioBurnerEvents_OnBufferEventHandler  (this.OnBurningBuffer);    
           m_audioBurner.OnTestWriteDisabled -=new IAudioBurnerEvents_OnTestWriteDisabledEventHandler(this.OnTestWriteDisabled);

           m_audioBurner                = null;
      }
}

Where are some signatures of functions :

void OnProgress(int Percent, int TimeRemaining)

void OnBurningBuffer(int Percent)

private void OnTestWriteDisabled(ref bool CancelBurning)

It's All!!

Regards,

Dmitry

I'm using something called AutoIt. I believe it is more closely related to VB...so if you can show me an example in VB format. Even though, I think I'm calling everything correctly:
Create the Burner object, and ONLY attach the OnProgress to it. (Don't assign a drive or anything else to it)...but I've tried it both ways anyway.
But I'm getting errors. I don't know if these mean anything to you, if they are universal: Windows HRESULT value = -2147220992, Error Win Description (FormatWinError) = ??, Error Last DllError (GetLastError) = 14007

But I still need to know if it is sending 'dispatch' type events (which I am sure is yes), and if it is passing arguments to the Event Functions 'by reference'. If it is not dispatch or if it is by reference, that is the source of my problem.

Hello,

1) You should attach the Drive Object to AudioBurner Class !!!

2) The VB6 language has the special directive WithEvents that indicate that declared variable will handle events:

Declaration..

Code:

Public WithEvents objAudioBurner As StarBurnXLib.AudioBurner

Using ...

Code:

Private Sub objAudioBurner_OnProgress(ByVal Percent As Long, ByVal TimeRemaining As Long)
...
end

3) Is not clear - " .. 'dispatch' type events " ?!

The AudioBurner object is defined as ...

Code:

    coclass AudioBurner
   {
      [default] interface IAudioBurner;
      [default, source] dispinterface IAudioBurnerEvents;
   };

4) The Dispatch IDs ...

Code:

OnProgress has the DISPID 1
OnBuffer has the DISPID 2
OnTestWriteDisabled has the DISPID 3

5) The signatures of events ...

Code:

OnProgressInfo        = {CC_STDCALL, VT_EMPTY, 2 , {VT_I4,VT_I4} };
OnBufferInfo            = {CC_STDCALL,VT_EMPTY,1,{VT_I4}}; 
OnTestWriteDisabled = {CC_STDCALL,VT_EMPTY,1,{VT_BOOL|VT_BYREF}}; 

first value - is calling convention;
second value - is return type;
third value - is count of input parameters;
other parameters - are types of input parameters;

Regards,

Dmitry

Thanks, from your reply I believe that it should work...but it doesn't. I'll once again bring up the error I'm receiving, -2147220992. I did some searching and saw that error around the net with slightly different causes. Would you know specifically what in StarBurnX would throw that error?

Hello,

1) Probably the StarBurnX is not registerd! Try to call " regsvr32 StarBurnX.dll

2) Could you provide me code (or part of code ) where you burn audio data?
I need to see how you :
- create AudioBurner;
- attach Drive;
- describe callback function;

Regards,

Dmitry

1/ It's registered, or nothing else would work.

2/ Good idea, maybe you could translate.

Code:

$Reg_Drive = ObjCreate("StarBurnX.StarBurnX");  Create starburn object

$Reg_Burner = ObjCreate("StarBurnX.AudioBurner");  Create burner object

;The following parameters are: "Object", "Function being activated", "Object interface(optional)"
ObjEvent ( $Reg_Burner, "_BurnProgress", "IAudioBurner");  Set up burner to receive events

$Reg_Drive.Initialize("");  Initialize starburnx

$Drive = $Reg_Drive.Drives.Item(0);  Get drive

$Reg_Burner.Drive = $Drive;  Attach drive to burner

$Reg_Burner.Burn(0);  Burn

Func _BurnProgress($1stParam, 2ndParam);  Function to process the OnProgress events

;When the objevent receives an event it is sent to this function to do whatever needs to be done with the info.

EndFunc

Let me know if you need to see anything else to get a better idea.

NOTE: Something I just noticed that I don't understand. The audioburner events are their own interface, and not just a part of the "IAudioBurner" interface? If I change the 3rd optional parameter in the ObjEvent to "IAudioBurnerEvent" I get an error description of "Library not registered." But shouldn't it be registered since everything else is registered and works. Or does that not matter? Note, although it says not registered I still see the progress with the X samples provided.

Thanks.

Are you still looking into this from what I provided, or you just don't know?

Hello,

Hmm it is not clear how are you specifying that you want to handle the OnProgress event exactly? AudioGrabber has two events OnProgress & OnFileCompressingProgress!

Regards,

Dmitry

You're right, here is a corrected example...minor tweak specifying OnProgress.

Code:

$Reg_Drive = ObjCreate("StarBurnX.StarBurnX");  Create starburn object

$Reg_Burner = ObjCreate("StarBurnX.AudioBurner");  Create burner object

$Reg_Drive.Initialize("");  Initialize starburnx

$Drive = $Reg_Drive.Drives.Item(0);  Get drive

$Reg_Burner.Drive = $Drive;  Attach drive to burner

;The following parameters are: "Object", "Function being activated", "Object interface(optional)"
ObjEvent ( $Reg_Burner, "OnProgress_", "IAudioBurnerEvents");  Set up burner to receive events

$Reg_Burner.Burn(0);  Burn

Func OnProgress_OnProgress($1stParam, 2ndParam);  Function to process the OnProgress events

;When the objevent receives an event it is sent to this function to do whatever needs to be done with the info.

EndFunc

The error I get now is:
ErrorNumber = -2147319779 (8002801D)
ErrorWinDescription = Library not registered.
But every other function works so shouldn't it all be registered?

Hello,

Hmmm ... it 's strange ... could you check the AudioBurner properties - LastErrorCode & LastError !!!?

Both return 0.

OK, I took up the trusty OLE Viewer and searched through every COM object on the computer and I found every method, property, and interface for X except the AudioBurner and AudioGrabber Events.

Hello,

1) The "AudioBurner Class" object should BE in the OLEView

!

2) The "AudioGrabber" is NOT valid object!! The Grabber object should be used for grabbing the DATA and AUDIO tracks.

3) Are you sure that your example is crashed in the "Burn" call?

4) Could you tray to test the other X object (the DiscEraser for example)?

Regards,

Dmitry

1/ The class is there, I meant I don't see AudioBurnerEvents ANYWHERE in the OLE viewer. Inside the AudioBurner Class or out.

2/ I know.

3/ No it doesn't crash in the call, it crashes long before the call. It crashes from the setup to receive the events where it says "Library not registered". See the previous example (minus the actual files being added of course.)

4/ The DiscEraser works fine. If you mean to test if the Events are working in the DiscEraser, it is giving me the same "Library not registered".
