<DIV>Hi,</DIV>
<DIV>My problem was Solved!</DIV>
<DIV>Thanks to everyone! </DIV>
<DIV>Special thanks Clarke Brunt!</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I am use omniORB4.0.7 on win2000+vc7.1,</DIV>
<DIV>The problem isn't Cause by use sequence<struct> ,and it is caused by project setting lib file and runtime library mode!</DIV>
<DIV>The project setting choose "Multithreaded DLL(release build)" or "Debug Multithreaded DLL (debug build)". This is OK.</DIV>
<DIV>My application is work fine now!</DIV>
<DIV> </DIV>
<DIV>Application code :</DIV>

In VC6, under Project Settings, C/C++, Code Generation, Use run-time
library, you need to choose Multithreaded DLL (or Debug Multithreaded
DLL for debug build), and not either of the single threaded options, or
the ones which don't mention DLL (statically linked). I would guess that
VC7 has similar options?
