Author 64bit conversion problem for BIFF
Malay

2005-06-10, 4:00 am

Hi,

My application uses BIFF4 to write a binary file so that it can be
opened up in the windows environment in Excel 2003.

This works fine as long as the binary is built on 32 bit.

We are working on a porting of 64 bit.

After the 64 bit porting the excel application could not be opened in
Excel 2003. It is saying the data might have been lost and opening a
blank Excel screen.

If I open the excel file in the binary mode from Visual Studio, I could
see all the formatting information written with BIFF4 format are lost.
In fact all are truncated.

I am using a Little Endian conversion before writing the data to the
excel binary and using only short, int and char *.

Appreciate any help on this regard.

Regards,
Malay

You will get a better response in a WINDOWS newsgroup, rather than here
in comp.UNIX.programmer.
