In valid file Formate

I have write a small program that read PDF file and convert it to image. I get the file information using LFile::getInfo(); function. but this line generate the -9 error code. Although i have include the LTFile dll and lib in our project. The code that i have included in my project is given below.

Please help me


Thanks

The error message -9 means "Invalid file format", which in many cases means there's a missing file-format DLL. Are you sure you included all the needed DLLs with your application?
For example if you are loading or saving TIFF image you will need to include LFTIFU.DLL, LFFAXU.DLL and possibly other LF???U.DLL files (depends on the type of TIFF compression you use).

For more information, please see the help topic "Files to be Included with Your Application" in our C DLL help file.
