Messenger Wont Exit

[Leo Havmøller]

If I have used the IMessenger API, Messenger wont exit (shows that pesky
"There are other applications currently using features" dialog).

I have boiled it down to the following console sample, which only calls
CoCreateInstance() and Release().

AFAIK everything is released and cleaned up, but the application must be
closed before messenger will exit.

What am I missing?


#include <windows.h>
#include <objbase.h>
#include <stdio.h>
#include <conio.h>

const GUID IID_IMessenger =
{0xd50c3186,0x0f89,0x48f8,{0xb2,0x04,0x36,0x04,0x62,0x9d,0xee,0x10}};

const GUID CLSID_Messenger =
{0xb69003b3,0xc55e,0x4b48,{0x83,0x6c,0xbc,0x59,0x46,0xfc,0x3b,0x28}};

int main(int argc, char* argv[])
{
HRESULT hr;
IUnknown* pMsgr;

CoInitialize(0);
hr = CoCreateInstance(CLSID_Messenger, NULL, CLSCTX_ALL, IID_IMessenger,
(void**)&pMsgr);
printf("CreateInstance=%u=0x%X\n", hr, hr);
if (pMsgr)
{
pMsgr->Release();
}
CoUninitialize();

printf("Try to exit messenger now.\n");
_getch();

return 0;
}

hr = CoCreateInstance(CLSID_Messenger, NULL, CLSCTX_ALL, IID_IMessenger,

It seems that using CLSCTX_LOCAL_SERVER instead of CLSCTX_ALL solves the
problem.
