Allow Content copying

[mpatel]

Hello,

How do you not allow content copying from PDF file programmatically.
Is there any way you do not allow copying some content of the file but still can copy other part of the file.

I am using C++ and PDF-XChange 3.0 and converting Excel to PDF programmatically.

Following is the sample code for the way I use the PDF-XChange to convert Excel to PDF

SaverObj.CreateInstance(__uuidof(CPXCControl ));
SaverObj->SetParamStr(0,"Save.FullFileName",(LPCTSTR)pdfFileName);
SaverObj->SetParamStr(0,"Save.ShowSaveDialog", "No");
.....

WorkBook._Printout(,,,...,PDFPRINTERNAME,..)

Please help me soon as possible as this is an urgent issue.

Thanks in advance

Hello mpatel,

I believe you have posted in the wrong forum

As for the permissions yes they can be set using PXCp_SetPermissions , but this is a XCPRO40 Library function and I am not sure it is available in ver3.

Best,
Stefan

Do you have any code sample for that?

And can we set permission to particular content rather than on whole file content.

Thanks for your reply

Taken directly from the manual

Example (C++):

Code: Select all

    PDFDocument   hDocument = NULL;
    DWORD Permissions = 0;
    // Permits document printing and extracting text and graphics:
    Permissions = Permit_Printing | Permit_TextGraphicsExtractions;
    // Set this options (key length will be set to 40):
    HRESULT res = PXCp_SetPermissions(&hDocument, 40, Permissions);
    if (IS_DS_FAILED(res))
    {
        // Report an error
    }
    ...
    // Clean up
    PXCp_Delete(hDocument); 

Or at PDF Creation time:

Code: Select all

_PXCDocument*  pdf;
...
// Sets the encryption level to 40 bits
// and only permit to print the document
HRESULT res = PXC_SetPermissions(pdf, 40, Permit_Printing);
if (IS_DS_FAILED(res))
{
// Handle error
}
...

Cheers,
Stefan

Can you give me a link from where i can download the manual.

Thanks

Hello mpatel,

It comes along with the ver4 SDKs - there is no link just for that manual I believe, so here is a direct one for the ver4 PRO SDK:

I think you forgot to answer this question

Can we set permission to particular content rather than on whole file content.
Meaning i want user not to copy some portion of the file but they can copy other portion of the file.

Thanks

Hi,

All of the above settings are applied on the document Layer, and affect the whole document.

Hello,

THanks for your help.

i was able to apply security settings for 4.0 but
I would like to know can we apply Security settings on 3.0 or not because when you see
printer settings for 3.0 it does allow to change these security settings but some how i am not able to do it by code

here are the settings that i am using for 3.0

pxc30COM::IPXCControlPtr SaverObj = NULL;

HRESULT hr = SaverObj.CreateInstance(__uuidof(CPXCControl ));

SaverObj->SetParamStr(0, "Security.Enabled", "True");
SaverObj->SetParamStr(0, "Security.Type", "2");
SaverObj->SetParamStr(0, "Security.Perms128.ContentAccess", "False");
SaverObj->SetParamStr(0, "Security.Perms128.AllowCopying", "False");
SaverObj->SetParamStr(0, "Security.Perms128.Printing", "0");

I am using same settings for 4.0 but it is not working only difference is I am using PXCComLib.CPXCControlEx

Thanks for youe help again in advance.

Thanks
