Hello All,

Can anyone help me with an example written in C++ that shows how to create customized callbacks to monitor the progress of a
cube processing. While I was able to find some samples they were written in Visual Basic or C#. My program looks like this:


#import "C:\Program Files\Common Files\System\ADO\msado21.tlb" no_namespace rename( "EOF", "adoEOF" )
#import "C:\Program Files\Common Files\Microsoft Shared\DSO\msmddo80.dll" \
no_namespace named_guids \
rename ("GetObject", "dsoGetObject") \
rename ("Command", "dsoCommand") \
rename ("_Command", "_dsoCommand") \
rename ("Properties", "dsoProperties") \
rename ("Property", "dsoProperty")


int main(int /* a_argc */, char** /* a_argv */ )

{
// Initialize the OLE Library...
CoInitialize(NULL);

_ServerPtr pServer(CLSID_Server);
pServer->Connect("localhost");

_DatabasePtr pNewDb = pServer->GetMDStores()->Item(_variant_t(0));

// ...
_CubePtr pCube = pNewDb->GetCubes()->AddNew("TestCube",sbclsRegular);

// ... Define the cube

pCube->Update();
pCube->Process(processFull); // _I would like to be able to cancel this if the processing takes too long

pServer->CloseServer();
// Close the OLE Library...
CoUninitialize();
return 0;

}


I have seen in the associated msmddo80.tli file the functions
inline HRESULT _IDatabaseEvents::RaiseReportProgress ( IDispatch * * obj, short * Action, long * Counter, BSTR * Message ) {

HRESULT _hr = raw_RaiseReportProgress(obj, Action, Counter, Message);

if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));

return _hr;

}

But I do not know how to overwrite it and register it with pNewDb.

Thanks in advance,

Bogdan

oh, don't worry, Microsoft expects us to change programming languages every
2 years

LoL
I dont think that Microsoft is doing a very good job with their VB
developers; either.. It seems like they have this newfangled C#, and there
was one benchmark once that showed that code could be written so that it
runs faster in C# than VB.net-- so now everyone is climbing on the C#
bandwagon while everyone else gets screwed.

I mean-- Microsoft has C# fever; and they're screwing all their other
developers basically.

It's like-- www.sqlmag.com just came out with a survey that lists the most
popular languages; and VB was the four highest categories (like VB6, VBS,
VB.net, VBA or something ridiculous) were the 4 most popular languages..

And somehow Microsoft expects us all to _change_ how we write code just
because some beancounter came out with a new marketing term.

It just blows me away, the arrogance that this company has.

SUPPORT YOUR LANGUAGES FOR 50 YEARS MICROSOFT!!!
