CoCreateInstanceEx memory leak

[boray]

Hello,

I use CoCreateInstanceEx to instantiate an object on a remote computer.
And when the function call fails ( because the machine or the service is unvailable or anything else ), I can observe in the task manager a that the memory used by the process increases by about 4ko ( for each failed call ).

I can observe this phenomenum with W2000, but not with XP.

Does anybody know about this topic ? Is there a fix for W2000 ?

First thing show your Code.without seeing your code not Possible to tell exact reason what's the wrong your are doing here. Second in your program use smart pointer . third use use ::CoInitialize() and ::CoUnInitialize() in your code.


Thanx

Ok, here following is my code.
I just want to emphasis on that if the CoCreateInstanceEx call succeed there is no trouble i.e. no memory leak.


#include "windows.h"
#include "stdio.h"
#include "conio.h"


CLSID m_clsid;


void main( void )
{
CoInitialize(NULL);

HRESULT hr;
MULTI_QI qi[] = { &IID_IUnknown, NULL, S_OK };
COSERVERINFO srvInfo = {0, L"192.55.90.10", NULL, 0};

CLSIDFromString( L"{23459DE0-C53D-11D3-8BFF-00105AABB585}", &m_clsid );

while( !kbhit() )
{
hr = CoCreateInstanceEx(m_clsid, NULL, CLSCTX_REMOTE_SERVER, &srvInfo, 1, qi);

printf( "\r0x%08x 0x%08x %p %p ", hr, qi[0].hr, qi[0].pIID, qi[0].pItf );
if( qi[0].pItf )
qi[0].pItf->Release();

Sleep( 100 );
}

CoUninitialize();
}
