its a bugg ....?
i think it's a bugg ....
its only with wingdi device, the problem it's the same with odamfcapp
(some pen an brush not delete after select)
and after some select on a big dwg (500 ko) the gdi crash
have you a solution ?

is it possible to reproduce this problem in odamfcapp?
(i can't reproduce any crashes on files that is much bigger then 500kb)

yes, after many selection in this drawing, the gdi crash, and if you watch with a tool like gdileaks (from microsoft) you can see that not all the pen and brush are destroy....

thierry, could you please look, if you will still have problem with the version of exgigdigeometry.cpp, that you can find in folder george, server ftp.softdev.spb.ru (i'll send you login and password via private message).

i have a compile error ... 'odtruncatetolong' does not existe
---------------------------------------------
exgigdigeometry.cpp
d:\projet\communs\dwgdirect\dd_nonlibs\examples\ex render\win\exgigdigeometry.cpp(54) : error c2065: 'odtruncatetolong' : undeclared identifier

sorry - my error. please check out odround.h from same location to your dwgdirect's include folder.
sincerely yours,
george udov
thank you george, i have try your files. but the problem is the same. first i have recompiled the library, i have add some line to be sure to use the good file like that :
file* m_logfile;
m_logfile = fopen("c:\\testod.log","a");
fprintf(m_logfile, " wingdimodule createdeviceobject : \n");
fclose(m_logfile);
....
i run odamfcapp.exe with "gdiusage.exe ---gdi usage for windows xp/2000/nt 4.0" to watch the gdi memory with a little standard dwg
the gdi memory stat is:
first before select
bitmap 14
brush 5
dc 2
pen 0
second select
bitmap 14
brush 7
dc 2
pen 2
third select
bitmap 14
brush 9
dc 2
pen 6
and if i try with a more big dwg ... with a large select ...
first before select
bitmap 14
brush 5
dc 2
pen 0
second select
bitmap 14
brush 1252
dc 582
pen 2
third select
bitmap 14
brush 2505
dc 2
pen 1165
and after a few select gdi crash
my log file is
