Usually when the phrase "thread safe" is used it means that the same instance of the library can be accessed by different threads at the same time.

This means that Quick PDF Library is not thread safe because a single instance of Quick PDF Library can only be accessed by the thread that created the instance.

However, Quick PDF Library can be used in a multithreaded environment so long as a separate instance of the library is created by each thread.

For users of the ActiveX edition of the library, please note that this version has been compiled with the threading mode set to "single threaded apartment".

Hello,
i'm trying to read a huge file with almost 12000 pages and i need to performe text search on it. i've tried reading page by page but it tooks about 15 minutes. I tried to use
 
Parallel.For(0,pageCount,(i)=>{ qp.SelectPage(i);
s = qp.GetPageText(3)});
 
public string GetPageText(int ExtractOptions)
{
   if (dll == null) return "";
   else
   {
         IntPtr data = dll.QuickPDFGetPageText(instanceID, ExtractOptions);
         int size = dll.QuickPDFStringResultLength(instanceID);
         byte[] result = new byte[size];
         Marshal.Copy(data, result, 0, size);
         return Encoding.UTF8.GetString(result);
   }
}
 
but i receive a Corrupted Memory Exception
          IntPtr data = dll.QuickPDFGetPageText(instanceID, ExtractOptions);
 
Is QuickPDF tread safe?
Thanks!
