I've been receiving pdf files that I have been processing with the PDFsharp libraries. These files where 128-bit RC4 encrypted. Now I getting files that are 128-bit AES encyption.
I'm getting this exception "The PDF document is protected with an encryption not supported by PDFsharp."
Is AES just not supported, or do I need to change the method in which I open the file? [code]...

I am attempting to find some code to use in VB.NET to decrypt a string that has been encrypted using the Java crypto libary.All of the code I have found so far uses an Initialisation Vector and Key to decrypt but the string has been encrypted using the Key only. (Using an Initialisation Vector is apperently an optional step in Java).Does anyone know of code that I can use (preferably in VB.NET but i could convert C#) to decrypt AES 128 Bit encoded string without an Initialisation Vector?

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

View 1 RepliesI have many container files on a hard drive, inside of them are many images. I have to get a particular image by using an ID to do this I have to go trough each of the container files and find the one which has the ID in it then I can retrieve the image.
I think I have 3 options:
load all the images at start up into memory, some images may or may not be used. as I need each image go through all the container files and open the image into memory. create a dictionary of IDs and what file they are in at start up and then get each image as I need it without have to go through all the container files.

View 1 RepliesI am using Visual Studio 2008 Professional Edition, and I have a large windows forms project I have been working on. My computer froze up and I had to reboot. After reboot I opened my project, all the files loaded although I got a message telling me that the document load was skipped because of the way the project opened the last time. I am able to debug and run the program so the app is ok. but when I double click on a form to open it nothing happens. Even if i right click it and select "View Designer" or "View Code" nothing happens. No errors just nothing. I was able to open other projects with no problem but not this one, and this project is the only one that matters.

I am opening a large PDF file using the following
Process.Start(Application.StartupPath & "PREVI.pdf")
I have two questions:
1) Is there a way to go directly to a page number?
2) Can I write a code to have the table of contents show up on the left side of the document so users can click on to go to different sections of the document, not sure if this needs to be done while creating the PDF or if we can do it by code.
