Hi , I am facing one exception which I don't understand kindly can you help me. Problem statement: I am giving a high (128-bit AES) encryption level pdf as a input to AbbyyEngine->GetNumberOfPagesInImageFile(filename, 0) API and its throwing the exception. Kindly can you help, Its not showing any exception information, mostly it would be internal error/exception. how to get the number of pages in high encryption pdf file.
If its a normal pdf, I am able to get the number of pages but not working for high 128-bit AES encryption pdf file. Kindly can you help me. int ReadImageHeaderInfo(LPTSTR FileName, int *Number, BOOL *Supported) { *Supported= FALSE; *Number= -1; try { *Number= cpAbbyyEngine->GetNumberOfPagesInImageFile(FileName, 0); } catch (...) { return -1; // something wrong with the file! } if (*Number <= 0) return -1; *Supported= TRUE; return 0; } Thanks,

As mentioned in the description of the IEngine::GetNumberOfPagesInImageFile() method in the Developer's Help article API Reference → Engine Object (IEngine Interface) → Processing Methods, the PasswordCallback parameter should not be 0 if you are trying to open a password-protected PDF file. From what I understand, you are trying to open such a file.
Therefore, you should implement the IImagePasswordCallback interface and pass an object derived from this interface to the IEngine::GetNumberOfPagesInImageFile() method. Please find more information in the Developer's Help file articles API Reference → Engine Object (IEngine Interface)→ Processing Methods and API Reference → Image-Related Objects → IImagePasswordCallback.
