Does Borland Support COM ?

[XxReaperxX]

Is there a way I can get a COM object to work under Borland?

What version? All versions upper than 3.2 supports different versions of COM. John Fill

got any sample code showing how to use a COM object in borland? not how to make one, but how to use one with a program

 

[Cagliostro]

you should use CoCreateInstance with CLSID of object you're looking for. You get an interface pointer and work with it or query other interfaces. Pay attention on return codes.

CoInitialize(NULL);
IDispatch* pDisp;
IUnknown* pUnk;
CLSID clsid;
CLSIDFromProgID(cApp,&clsid);
CoCreateInstance(clsid,NULL,CLSCTX_SERVER,IID_IUnknown,(void FAR*FAR*)&pUnk);
pUnk->QueryInterface(IID_IDispatch,(void**)&pDisp);
..work here
pDisp->Release();
pUnk->Release();
CoUninitialize();

what's the header file for CoInitialize and stuff? its not in ole2.h

 

[Cagliostro]

In ole2.h are all includes you need. So just #include<ole2.h>. What version of C++ are you using? John Fill
