Hi

I'm using Starburn 10.0.0.4128 under Delphi 2010 to burn DVD video files + some proprietary files to a disk. However i am finding that after burning and releasing the burner the files that have been burned are still locked. They remain locked until i restart the application.

This is the method i use for building the UDF file tree:
Code:
procedure TsbBurner.PrepareDVDFilesFileTree(sDiscLabel:string;
                                            sPublisherName:string;
                                            ssVideoTSFiles:TStrings;       // Files for VIDEO_TS folder
                                            ssRootFiles:TStrings;          // Files for Root folder
                                            sOtherFolder:string;           // Name of other folder
                                            ssOtherFolderFiles:TStrings);  // Files for Other folder
var
  l__ULONG__Status : DWORD;   
  l__CHAR__ExceptionText : Packed Array[ 1..1024 ] Of Char; 
  l__EXCEPTION_NUMBER : EXCEPTION_NUMBER;
  pVideoTSFolder:pointer;
  pAudioTSFolder:pointer;
  pOtherFolder:pointer;   
  l__PVOID__NewNode: Pointer;
  sMessage: string;
  i: Integer;
  FYear, FMonth, FDay: Word;
  FHour, FMin, FSec, FMSec: Word;

  procedure _AddFile(sFilename:string;pFolder:Pointer;sNameOnDisk:string='');
  var
    pNameOnDisk: Pointer;
  begin
    if sNameOnDisk='' then
      pNameOnDisk:=nil
    else
      pNameOnDisk:=Pchar(sNameOnDisk);

    l__EXCEPTION_NUMBER :=
            StarBurn_UDF_Add(
                PCHAR( @l__CHAR__ExceptionText[1] ),
                sizeof( l__CHAR__ExceptionText ),
                l__ULONG__Status,
                Pchar(sFilename),
                pNameOnDisk,
                pFolder,
                l__PVOID__NewNode
                );

    // Check for success
    If l__EXCEPTION_NUMBER <> EN_SUCCESS Then
    Begin
      sMessage:= Format('%s (%d,%d): %s',
                        ['Failed to add '+sFilename,

                         l__ULONG__Status,
                         PAnsiChar(@l__CHAR__ExceptionText[1])]);
      Logger.Log(sMessage);
      Raise Exception.Create(sMessage);
    End;
  end;

begin
  ShutDownFileTree;
  l__ULONG__Status := ERROR_GEN_FAILURE;

  ZeroMemory(@l__CHAR__ExceptionText, sizeof( l__CHAR__ExceptionText));
  FDVDFilesRootFolder:=nil;
  ZeroMemory(@UDFControlBlock, sizeof( UDF_CONTROL_BLOCK));

  Logger.Log('Formatting folders...');

  // Format root directory
  l__EXCEPTION_NUMBER :=
            StarBurn_UDF_Add(

    l__EXCEPTION_NUMBER :=

            pchar(sOtherFolder),
            FDVDFilesRootFolder,
            pOtherFolder
            );

                       PAnsiChar(@l__CHAR__ExceptionText[1])]);

    Logger.Log(sMessage);
    Raise Exception.Create(sMessage);
  End;
end;


Free it as follows:

Code:
procedure TsbBurner.ShutDownFileTree;
begin
  // Was file tree allocated
  if (ISO9660JolietFileTree <> nil) then
  begin
    Logger.Log('Destroy: FileTree');
    StarBurn_Destroy(ISO9660JolietFileTree);
    ISO9660JolietFileTree := nil;
  end;

  // Destroy UDF
  If FUDFControlBlockCreated and (UDFControlBlock.m__PVOID__Body <> nil) Then
  begin
    Logger.Log('Destroy: UDFControlBlock');
    StarBurn_UDF_Destroy(StarBurn_UDF_GetNodeObject(FDVDFilesRootFolder),
                         @UDFControlBlock);
    FDVDFilesRootFolder:= nil;
    FUDFControlBlockCreated := False;
  end;
end;



As well as performing the usual functions for unlocking and releasing the burner.

Thanks

1) We don't support V10 for at least two years or so... Update to V12 and re-new your ASM plan to get support.

2) You don't destroy UDF file tree object after burning so keep all file handles opened. That's why files are "locked" until you don't close your app (so OS will close handles for you).
