i'm using this:

blocksize dd 8192
buffer db 8192 dup (?)
rw dd ?
hfile dd ?
invoke CreateFile, filename, GENERIC_READ, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0
mov hfile, eax
; return file-open error
or eax, -1
invoke ReadFile, hfile, addr buffer, blocksize, addr rw, 0
invoke CloseHandle, hfile

whenever i call ReadFile i get an error message box (see image). so no data is read, and the app quits. why?

How are you defining filename?

If it's something like

filename db 250 dup(?)

then you need to use ADDR filename in your CreateFile invoke.

actually the calls to CreateFile and ReadFile are in a proc. filename is a dword...

like this:
ProcessFile proc uses edi ebx filename: dword
ProcessFile endp

this is called with
invoke ProcessFile, addr lpstrFilename

lpstrFilename is dup MAX_PATH (?)
