Salutare,

Am mai multe instante ale unui program. Fiecare expune un obiect COM la care ma pot lega.

Am obtinut lista proceselor ( Process.GetProcessesByName() ) si lista obiectelor ( UCOMIRunningObjectTable.EnumRunning() )

Cum fac sa stiu care proces expune care obiect? Am incercat in ordinea enumerarii dar nu merge.

C#, .NET 4

Vezi in codul din GetCurrentDTEObject(), face ceva asemanator: http://developergeek...sual-studio-net

In acel exemplu se compara ProgID-ul care-i acelasi pentru toate instantele, deci nu te ajuta.
N-am reusit sa gasesc o cale de a afla ce proces gazduieste un anumit obiect.

Daca tu ai creat serverul, cred ca nu-ti ramane decat sa introduci o noua functie/interfata care sa-ti returneze PID-ul curent sau alte asemenea.

Serverul nu este creat de mine, insa am gasit o functie ce ruterneaza pID-ul... insa acum vad ca UCOMIRunningObjectTable.EnumRunning() imi returneaza de fapt mereu ultimul obiect....

Functie oferita de server sau de COM?

Nu inteleg la ce te referi. Gandeste-te ca ai 10 excel.exe deschise si vrei sa parcurgi fiecare instanta, sa te legi la ea, sa vezi daca are deschis un document, iar daca nu are sa deschizi tu unul si rulezi un macro (de exemplu).

Nu discutam de API-ul MS Office, este doar un exemplu.

La excel e chiar simplu fiindca monikerul va indica spre fisierul deschis, nu spre excel.exe

void testRunningObjectTable()
{
	IRunningObjectTable* rot;
	GetRunningObjectTable(0, &rot);

	IEnumMoniker *enumMoniker;
	rot->EnumRunning(&enumMoniker);

	cout << "Running objects" << endl;

	IBindCtx* bindCtx;
	CreateBindCtx(0, &bindCtx);

	IMoniker* moniker;
	IMalloc* allocator;
	CoGetMalloc(1, &allocator);

	while (enumMoniker->Next(1, &moniker, NULL) != S_FALSE)
	{
		LPOLESTR displayName;
		moniker->GetDisplayName(bindCtx, NULL, &displayName);

		wcout << displayName << endl;

		allocator->Free(displayName);
		moniker->Release();
	}

	allocator->Release();
	enumMoniker->Release();
	bindCtx->Release();
	rot->Release();
}

Nu-i .NET, dar intelegi ideea.
