Hi guys, does anyone know how to create a own memory viewer what does show memory similar as HxD?Offset / Hex etc you know. So normaly I would open any choosen process and read entire memory from 0 - F using VirtualQuery and then I need to show it anyhow.Not sure whether I should use a edit control or anything else.Next question would be how to show it with offset addresses / hex / ASCII and how to update the memory if it does change.Hhmmm.Has someone any ideas / hints how to handle that?Just wanna create a memory viewer + some search function only. Thank you

PE File Format question
by null_endian- 1 reply
- 3.7k views
In the PE file format, there is the DOS_HEADER and then right after that, there is a section called doscode which is by default 64 zero bytes. However, sometimes it is filled with an arbitrary number of bytes. Some PE files have a lot of bytes here, others don't. How can I calculate the number of bytes that doscode will be? There doesn't seem to be any field in the DOS header which specifies this. Thanks.
