Re: Trying to check e_print permission in PDFTron/C# and I get an exception

[Support]

 

Do you check if the security handler is not NULL.

Also, do you check for doc_open permission?  Your code should be something similar to this 

 

SecurityHandler s = doc.GetSecurityHandler();

if (s!=null && s.GetPermission(SecurityHandler::e_doc_open)) {

    ...   s.GetPermission(SecurityHandler::e_print)

}

else {

    if (doc.InitStdSecurityHandler("my pass "))  {

              if (s.GetPermission(SecurityHandler::e_doc_open))

                  ...  s.GetPermission(SecurityHandler::e_print)

    }

}

 

If this does not help, could you please send a test project along with a test file to support at pdftron. Than you!

I have read a few posts and I think I understand what I need to do - init the security handler, then query it for the permission. But I get an exception when I try that.

Below is from the immediate window in Visual Studio during debugging. I broke at the point where I have a valid PDFDoc object. I get true returned from InitSecurityHandler. GetSecurityHandler returns an object. GetPermission gets an exception.

?oDoc

{pdftron.PDF.PDFDoc}

oDoc.InitSecurityHandler()

true

? oDoc.GetSecurityHandler()

{pdftron.SDF.SecHdlrFwd}

    [pdftron.SDF.SecHdlrFwd]: {pdftron.SDF.SecHdlrFwd}

? oDoc.GetSecurityHandler().GetPermission( SecurityHandler.Permission.e_print)
