Noobie Here!

[sub]

Things are really looking good, however, now I'm stuck on getting RESUME to work.
In posts #65 and #66 you gave me the code necessary for this function.
But once again I don't know know where to put it, and in what order.

Where do you want it to happen? ie, in response to what action by the user?

[jrockow]

In response to the popup window called by the Activate Item sub.
I have a button labeled RESUME in the popup.

Also, I'm trying to call the PopulateList routine after DELETEing a file, but having a problem inserting the call in the popup.vb.
Getting the "not declared" error again.
How do you repaint the screen after a delete?

[jrockow]

Somewhere in all my reading I came across this statement:

PluginHelperFactory.GetPluginHelper().GetPlaybackP roxy().GetPosition()

Is this anything I'll need for RESUME to work?

This type of problem is nothing to do with NextPVR. This is just straight forward question relating to programming in modern languages that uses classes. These are two different classes, and they have different methods available.

There is lots of ways you can deal with this sort of situation. In this case, the most straight forward way would be to make use of the PluginCallback, which was made to help passing info back from popups. ie, in the popup class you can call:

Code:

callback.PluginCallback(this, "Resume", null);

Then in the main plugin you'd act on that message:

Code:

public void PluginCallback(object source, string command, object args)
        {
                if (command == "Resume")
                {
                        // retrieve resume info
                        int duration = 0;
                        int position = PlaybackPositionHelper.GetPlaybackPosition(filename, out duration);

                        Hashtable resumeMetaData = new Hashtable();
                        resumeMetaData["RESUME_FROM"] = position;
                        PluginHelperFactory.GetPluginHelper().PlayVideoFile(filename, resumeMetaData);
                }
                else if (command == "Delete")
                {
                        ...delete file....
                        PopulateList();
                }
        }

The problem for today is getting RESUME to work.
When I click the button the error I get is ....

"The method or operation is not implemented"

In your sample code I don't see anything like...
"Implements NUtility.IPluginCallback.PluginCallback"
which I assume I need?

I tried adding it (at various locations) without any success.


Here is my sub....

(In an effort to simplify troubleshooting, I hardcoded the filename)

Public Sub PluginCallback1(source As Object, command As String, args As Object) Implements NUtility.IPluginCallback.PluginCallback
If command = "Resume" Then
' retrieve resume info
Dim duration As Integer = 0
Dim position As Integer = PlaybackPositionHelper.GetPlaybackPosition("R:\JOLOC\CASTLE\CASTLE_20140317_22012300.ts", duration)

Dim resumeMetaData As New Hashtable()
resumeMetaData("RESUME_FROM") = position
PluginHelperFactory.GetPluginHelper().PlayVideoFile("R:\JOLOC\CASTLE\CASTLE_20140317_22012300.ts", resumeMetaData)
ElseIf command = "Delete" Then
' ...delete file....
PluginHelperFactory.GetPluginHelper().ActivatePopup(Nothing)
PopulateList()
End If
End Sub



I also noticed I have this paragraph that looks identical to the one above, except for the name...

#Region "IPluginCallback Members"
Public Sub PluginCallback(source As Object, command As String, args As Object)

(identical code as above SUB)

End Sub
#End Region

Should this be in here?

I'm not sure whether the original Test3 plugin you were looking at had it, but it was definitely in the Test4 plugin I posted recently:

Code:

namespace Test3
{
    public class Test4 : NewStyleButtonListPlugin, IPluginConfiguration, IPluginCallback
    {

Code:

public void PluginCallback(object source, string command, object args)
        {
        }

I started over again.
I removed the sub and all code pertaining to RESUME, removed the "Implements IPluginCallback" call.
Then I first put back the Implements call; now I have this....

Public Class Class1
Inherits NewStyleButtonListPlugin
Implements IPluginCallback
' Implements IPluginConfiguration (commented out)

When I put back the Implements IPluginCallback (above), it created a new plugincallback sub.
I put back the RESUME code and it now looks like this...

Public Sub PluginCallback(source As Object, command As String, args As Object) Implements NUtility.IPluginCallback.PluginCallback
If command = "Resume" Then
Dim duration As Integer = 0
Dim position As Integer = PlaybackPositionHelper.GetPlaybackPosition("R:\JOLOC\CASTLE\CASTLE_20140317_22012300.ts", duration)
Dim resumeMetaData As New Hashtable()
resumeMetaData("RESUME_FROM") = position
PluginHelperFactory.GetPluginHelper().PlayVideoFile("R:\JOLOC\CASTLE\CASTLE_20140317_22012300.ts", resumeMetaData)
ElseIf command = "Delete" Then
' ...delete file....
PluginHelperFactory.GetPluginHelper().ActivatePopup(Nothing)
PopulateList()
End If
End Sub


I have removed any of the "#Region" code I mentioned earlier.

The end result is the same; when I press RESUME I get an error.......
(I included the lines mentioned in the error text)

It looks like you've created your own class called PlaybackPositionHelper.vb, and you're trying to use that, instead of the one supplied by NextPVR.

Delete your class, and make sure you have the VB.NET equivalent of "using NUtility;" and "using NShared;" at the top of your class.

After compiling the "#Region" stuff came back.
I guess it's supposed to be there?

[sub]

#regions, and just a cosmetic thing, so you can click + or - to collapse or expand that section of code.. The editor usually adds them when it implements an interface, to show the methods as grouped together.

They wont be causing you any problems.
