Thank you Sven!

I modified some code written by Kevin Voell, and ended up with the following
PB/DLL app.

The app finds the location of the 'Code Section' and 'Base of Data'.

Many thanks,

- Nathan.

#COMPILE EXE
#INCLUDE "WIN32API.INC"
#INCLUDE "COMDLG32.INC"

FUNCTION PBMAIN()
   LOCAL ExeHdrInfo AS IMAGE_NT_HEADERS
   LOCAL DOSHdr AS Image_DOS_Header
   LOCAL hDLG  AS LONG
   Path$ = CURDIR$
   Style%    = %OFN_FILEMUSTEXIST OR %OFN_HIDEREADONLY OR %OFN_LONGNAMES
   RESULT% = OpenFileDialog(%HWND_DESKTOP, "Open File", f$, Path$, "Executable Files|*.EXE|All Files|*.*", "EXE",%OFN_FILEMUSTEXIST OR %OFN_HIDEREADONLY OR %OFN_LONGNAMES)
   X% = FREEFILE
   OPEN f$ FOR BINARY AS X%
   GET X%,, DosHdr
   SEEK X%, 0
   SEEK X%, DosHdr.e_lfanew + 1
   se% = SEEK(x%)
   GET X%,, ExeHdrInfo
   CLOSE X%

   DIALOG NEW %HWND_DESKTOP, "EXE FILE INFO", ,,200,80,%WS_SYSMENU, TO hDLG

     BaseOfCode$ = FORMAT$(ExeHdrInfo.OptionalHeader.BaseOfCode)
     CONTROL ADD LABEL, hDLG, 101, "Base of Code:" + BaseOfCode$, 10, 4, 200, 10
   
     BaseOfData$ = FORMAT$(ExeHdrInfo.OptionalHeader.BaseOfData)
     CONTROL ADD LABEL, hDLG, 101, "Base of Data: " + BaseOfData$, 10, 14, 200, 10
     
          CONTROL ADD LABEL, hDLG, 101, "Filename: " + "..." & RIGHT$(f$, 20), 10, 28, 200, 50
   
   DIALOG SHOW MODAL hDLG

END FUNCTION

I'm looking to find the offset of the Code Section of any given EXE file.

An article called 'The Portable Executable File Format from Top to Bottom'
by Randy Kath mentions a PEFILE.h. (http://www.eccentrica.org/Mammon/Text/pefile.html)

I believe before i can get started i'll need this..

Hands?


Thanks!!
