[omniORB] Win32 CORBA

[Marek Cichy]

Hi all
I finally created a CORBA server which works properly as a Windows
console application (using VS 9.0). I have to create another one, but as
a Win32 application. So, I just copied the code from one to another, and
something works. My question are:
Where do I have tu put ORB's initialization sequence in order to not to
lose control over application window after call orb->run()?
Is it possible to initialize orb without command line parameters?
ORB_init()?
Below is a std code created by VS and ORB initialization injected inside.
Thanks in advance for any help

int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);

// TODO: Place code here.
MSG msg;
HACCEL hAccelTable;
int argc;
char* argv[1];

try {
// Initialize orb
CORBA::ORB_var orb = CORBA::ORB_init(argc,argv);
// Get reference to Root POA.
CORBA::Object_var obj = orb ->resolve_initial_references("RootPOA");
PortableServer::POA_var poa = PortableServer::POA::_narrow(obj);
// Activate POA manager

PortableServer::POAManager_var mgr = poa->the_POAManager();
mgr->activate();

// Create an object of Simple_If_Impl

Simple_If_Impl* simple_servant = new Simple_If_Impl();

PortableServer::ObjectId_var mySimpleId =
poa->activate_object(simple_servant);

ISimple_Interface_var siv = simple_servant->_this();

if( !bindSimpleToName(orb, siv) )
return 1;
// Write its stringified references to stdout
CORBA::String_var strSimple = orb->object_to_string(siv);

// Accept requests
orb->run();

}
//catch omitted

return 0;

It depends. You can either use orb->perform_work() interleaved with the
windows msg processing or you can run orb->run() in a separate thread
(which is what I prefer).
Note that it shouldn't matter in which thread you run your CORBA init
sequence as long as you run orb->run() in it's own thread.
Note also that you have to take a bit of care on shutdown. (Common
thread sync / wait for completion problems.)

Just don't call orb->run(). omniORB dispatches everything from its own
threads, so you don't need to call run() at all. (Unless you use the POA
main thread model.)

ORB_init()?

ORB_init always expects some command line parameters, but it doesn't
know or care if they really came from the command line. It's generally a
good idea to give it the real command line, though, since that allows
you to easily turn on tracing and things like that.

Cheers,

Duncan.
