Open File for Reading while Writing

My app opens a log file for writing on startup. It closes it (CloseHandle API) when the app exits. It writes lines to the log file as the program runs.

What I would like to do is open another handle to this file for just reading during the course of the program, to just display its contents to the screen. Is there a combination of flags for the openings (CreateFile) that will allow me to do this? Right now opening for reading fails.

Thanks.

VB Code:

'open for writing
hFile = CreateFile(FixDir(App.Path) & LOGFILE, GENERIC_WRITE, FILE_SHARE_READ, _
        ByVal 0&, CREATE_ALWAYS, FILE_ATTRIBUTE_ARCHIVE, 0)
 
'open for reading
hRead = CreateFile(FixDir(App.Path) & LOGFILE, GENERIC_READ, FILE_SHARE_READ, _
        ByVal 0&, OPEN_EXISTING, 0, 0)

Why not open the log file and write its contents to a Locked Text box?

That's not the problem. Trying to open the file for reading fails when I already have the file open for writing the way I'm doing it now.
