PE Files - edit existing section?

[Damnation]

This code (an old version of kernelex, written in VC++ 6.0) edits PE files.

The code adds a second .data section to dll files instead of the existing .data section.

I'd like it to edit the existing section, rather than adding a new one.

If anyone knows how to fix it would be appreciated.

If the new data won't fit in the old section, the section must be expanded which is much more difficult than adding a new section. KernelEx adds a new section because it is simpler and works just fine.

If your goal is to modify KernelEx, don't.
If your goal is finding sample code for robustly adding new data to an existing section, don't look at KernelEx, look elsewhere.
