A way to protect your pdf files is to encrypt your pdf files by setting passwords. We have developed a dll to open the encrypted pdf files without telling the passwords to the end users.
The dll contains only one function that is very easy to use: Code:
Dll.registerFunction(getAdditionalFile('OpenPdf.dll'),
"LoadPdf", "LoadPdf", "cdecl", "long", "string", "string");
funtion LoadPdf(pdffile, password);
password - The password of the pdf file to open. Please look into the attached sample |
