long file name problem?

[Guest]

I am using Windows XP embedded SP2 with features 2007. One operating system I
built works fine except that long file names will be truncated to 8
characters. And this caused erros for one of my applications. For example, my
application will need MCS5xx32_B2300.DLL but I see MCS5XX~1.DLL under
windows. I believe this caused the above problem. I appreciate your help to
let me know which component(s) should be added to get rid of this problem.

Thanks,

Changyi

I don't think this problem is related to missing/wrong components. I think
we need more information about how you built your system. One possibility
is that when you transferred files from the build environment to the target
for FBA, you used a technique that did not support long file names (e.g.
DOS). Please describe how your files were moved both before and after FBA.

Hi, Henry,

I built and copied the Run Time Image under "C:\Windows Embedded Images" to
a CF card first. Then the embeddded PC ran through FBA and system booted up
without any problem. Then I installed my Labview application (Labview Runtime
support installed first). When I try to run my application, and my
application started to looking for MCS5xx32_B2300.DLL but my application
installation generated MCS5XX~1.DLL instead. I tested my application on full
version windows XP professional, no problem at all.

Thanks,

Changyi

Changyi,
Your doing a couple of things that I don't know very much about so hopefully
an acutal expert with help out. Running FBA directly from the CF device is
unusual since that would be very slow and result in many write cycles that
shorten the life of the flash. It's much more common to run FBA on a hard
drive if possible. Since you installed Labview and your application after
FBA, did you do an fbareseal on your image? Since you are apparently
running the image from flash, are you using EWF?

The problem may be in the way the Labview installer views the flash that you
are installing on to. Lacking certain hardware support, flash is generally
viewed as removable storage. Maybe the installer is getting confused by
that fact and somehow you get short file names. Just a guess.

Henry,

Thanks for your inputs. My installation application contains the files in a
compressed format with filenames stored with 8.3 formatting. On installation,
the files are decompressed and the full filenames restored. But the embedded
operating system I built can't restore the full filenames.
