Hello.

I am using QuickPdf library version 9.13, calling it trough .NET.
My question is:
Is it necessary to cal RemoveDocument function, if I manually call Release(sintax below) at the end ? Will the "Release" method implicitly remove the document from the memory ?

public void Release()
        {
            if (dllHandle != IntPtr.Zero)
            {
               foreach (int instanceID in shutDownList)
               {
                    DebenuPDFLibraryReleaseLibrary(instanceID);
               }
               FreeLibrary(dllHandle);
               dllHandle = IntPtr.Zero;
            }
        }

Thank you for reply.
Bostjan

The reason why I want to know is this error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Hi Bostjan,

the reason for this issue should be there where you call (and how you call) the library from your .net-app. Mostly the error will raise while handling the returning string-values from the QuickPDF.dll. With numeric values the error won't raise.

Cheers and welcome here,

Ingo
