Thanks very much for this test source (could you, please, consider
moving it into the "examples", which are also present in the binary
distributions?).
Please find attached a modified version of "demodll.c". It solves a
problem with windows "disappearing" in the "background".
It also solves a problem which is probably related to "snprintf".
I noticed that the line:
snprintf(msg, sizeof(msg), "%s: last error = %i", func, e);
when displayed in the MessageBoxW gives:
open: last error = 3XX0X ("X" are just strange square boxes)
It is sufficient to put any character after "%i" in the "format string",
so I added a space character:
snprintf(msg, sizeof(msg), "%s: last error = %i ", func, e);
then the output is correct:
open: last error = 3
Let me also say that, if I try to run this demo code compiled with
arm-wince-cegcc (instead of arm-wince-mingw32ce), the usedemo.exe is
executed, but then it stays in memory (together with the demodll.dll), and
they cannot be killed/terminated (one needs to reboot the PNA in order to
get rid of them).
Finally, let me go back to the "problem" of missing ".dll" file name
extensions. As demonstrated by the above "demodll", it does not matter for
the Windows CE. However, do try to use the "Dependency Walker" with this
small "demodll.dll" and with the "usedemo.exe". You will immediately
notice that it will not be able to find "COREDLL" when trying to resolve
the "DEMODLL" imports (because the file is called "COREDLL.dll"), and it
will not be able to resolve any imports in the "usedemo.exe", because it
tries to find "COREDLL" and "DEMODLL" files, while the files are called
"COREDLL.dll" and "DEMODLL.dll".
So, could you, please, consider changing the "standard dll naming
convention" in cegcc/mingw32ce, so that there are always the ".dll"
file name extensions added? (Well, the "Dependency Walker" is a really
useful utility. It would be nice to be able to use it with
cegcc/mingw32ce, too.)
Best regards,
Jacek.
