Hi there.

I just want to get .pdf file related inforamtion like Title, Author, Subject, Keywords, Created, Modified etc.

1. Do we have Windows APIs for the same?
2. Or I need to use Adobe provided APIs. In case Adobe APIs, then can someone please suggest some pointer in regard to Adobe APIs to do the job.

Thanks & Regards

For Modified Date and Time I can use _strtime(timebuf) and _strdate(datebuf) APIs. Any pointers for Title, Author, Subject, Keywords will be helpful...Thanks

The information you desire can easily be obtained by calling StgOpenStorageEx(), and then getting an IPropertyStorage interface.

Windows has no PDF APIs.

Here's a link[^] to the Adobe PDF SDK - you need a license from Adobe to use that.

There are other alternatives - Google for "PDF SDK".

If you were using Mac OS X, you could be using PDFKit[^] - PDF support is built into OS X.

Thanks. Anyway, like we can get file info. using Windows API, Can't we use Windows APIs to get info. for .pdf file. They are also files...I mean if I can get its modified date/time using Windows APIs then there should be some way to get rest of the information. Just want to know about this for knowledge purpose.

As Stuart said there is no native Windows API to read a .pdf file. As it's an Adobe file format and not a Microsoft format why would there be?

Date and time info is common to all files in the file system so there are API ways to read and write it. The data you're looking for is specific to Adobe's pdf format, so you'll need to look elsewhere like the links Stuart gave to find a way to programatically read it.

No, it's part of the compound document interface.

c) Changed the Resources Accordingly
d) Created a Function which will be called from Dll (this Function is empty)

d)Created a Windows forms Application =>created a Form =>Added Button
=> On Click of Button i am Calling the dll function using pInvoke(DLLImport)

From the main Dll i call the serilisation of respective Dll.. the thing happening is like the my MFC Dll gives me Archieve Exception while retrieving the data.. the same does not happen if i am running the application not as Dll..

The top thing here is 64 bit EXEs cannot load 32 bit DLLs and vice versa.

A 32 bit EXE will run normally on a 32 bit OS and inside the WOW64 shell on a 64 bit OS.
It will execute on both nevertheless.

A 64 bit EXE will run only on a 64 bit OS.

So your statement "when i compile VC++ project on 32 bit machine then it wont work on 64 bit machine" is not true.

And if you have installed the 64 bit compilers, you can use Configuration Manager to change the platform from Win32 to x64 to build 64 bit binaries.

Character code for string in other language

Hi to all,

Someone helped me on other forum to convert a string in any language to it's bytes format, using following code.

string s = "François";
byte[] unicodeBytes = Encoding.Unicode.GetBytes(s);
byte[] aBytes = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(28599), unicodeBytes);

He told me to use WideCharToMultiByte() in C++ for above C# code.
He help me a lot.

But I want to know that, is there any method to get the character code for given value in string s to convert that string in bytes?

Is there any software or dlls to release the application with some evalution period?

Regards,
Aniket A. Salunkhe

You can typecast each character using wchar_t to get the unicode value or using char to get the ascii value.

int i = wchar_t(s[0]);
int j = char(s[0]);

I am getting wrong output when I have string in Arabic Language.

I want to convert a string (in any langauge) to bytes format as geiven in Annex A of
ETSI EN 300 468 V1.9.1 (2008-11)
Digital Video Broadcasting (DVB) :
Specification for Service Information (SI) in DVB systems

For that someone has suggested to use System.Text.Encoding. But to use that, I must know the codepage before compilation.

So is there any method to retrieve codepage?

You can get code page information using APIs like GetACP, GetCPInfo etc.
