OnJobDone does not triggered??

Question

Hi,
I use Adobe Acrobat Distiller 7 and C# 2.0. I must distinct each PDF jobs because I need to further save the generated document to database. It works okay in normal cases, but sometimes when the PC gets slow, then the PDF is not generated before Save is called, so that save function saves the older generated PDF to database and throws no exception. My solution is to use Semaphore to lock before distiller start generate document and release after OnJobDone is triggered. However the OnJobDone is never triggered. Can anyone tell me if the event is malfunction?
Here is part of the code:
private Semaphore _pool;
_pool = new Semaphore(1, 1); // init semaphore
pdf = new PdfDistiller(); // init distiller
pdf.bShowWindow = 0;
pdf.bSpoolJobs = 1;
pdf.OnJobDone += new _PdfEvents_OnJobDoneEventHandler(pdf_OnJobDone);
pdf.OnJobFail += new _PdfEvents_OnJobFailEventHandler(pdf_OnJobFail);
_pool.WaitOne(); // PSemaphore and start generate
wd.PrintOut(
ref objFalse, ref objFalse, ref oMissing, ref outPS, ref oMissing,
ref oMissing, ref oMissing, ref oMissing, ref oMissing,
ref oMissing, ref objTrue, ref oMissing, ref oMissing,
ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
closeDocument();
pdf.FileToPDF((string)outPS, (string)outPDF, "");
savePDFToDb();
void pdf_OnJobFail(string strInputPostScript, string strOutputPDF)
throw new Exception("generate Pdf failed");
void pdf_OnJobDone(string strInputPostScript, string strOutputPDF)
_pool.Release(); // VSemaphore

Have you tried a different charger and/or cable ? Do you know anybody else with an iPad so that you can try their charger and cable and they can try yours ?
Have you tried a reset to see if it charges after the iPad has restarted ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
