Dear all,

I am now developing a simple C/C++ program which is used to preview a
selected file. I use IExtractImage to extract the image. I expected my
program can preview all files that can be previewed in windows
explorer. It works with html documents, Office documents, image files
but not with pdf files, however. (With Acrobat Reader 7.0 installed)


I got the following error message while extracting preview image from
pdf file:


"The data neccessary to complete this operation is not yet available"


Can anyone tell me how to preview pdf files?

Thank you very much.

Regards,
Eva
 
Hi,

Because my program is implemented by Java mainly, I can't found a
solution from C/C++ within the open source libraries.
My colleauge found a java library to do it finally.
However, I left the company so I am not sure which library is using
now.

hope this can help you.
Eva
