Could somebody tell me how to convert RVA to file offset and viceversa ?

the formula is:

file_offset = (RVA - SectionVirtualOffset) + SectionRawOffset

SectionVirtualOffset is the base address of the section that contains your RVA, SectionRowOffset is the file offset of the section that contains the RVA. You can obtain both Virtual/Row offset from the section table.
In practice you calculate the distance of the rva from the beginning of its virtual section and use this distance in the file raw address of the section itself

Hi _ColdMind,
this question has been asked many times before and, I would like to suggest to use the search function. The function is accessible from any page (look at the top) or, for an advanced search, from this page: http://www.woodmann.net/forum/search.php?

Andrea, what are you doing here?

Best regards,

Thanks a lot AndreaGeddon - this is my key up to search and discover more information discussed on this forum and web. Also Je remerci to ZaiRon.

Hi

I'm sure you've found this already, I hope, but in this thread I posted almost exactly 24 hours before yours are some programming articles and a nice explanation of that called

Converting virtual offsets to raw offsets and vice versa

http://www.woodmann.com/forum/showthread.php?t=5423

Kind of ironic, even the vice versa is there

Cheers,

Thanks a lot Kayaker.
