Question: I start the MS Text-to-speech engine in a thread, in order to avoid a crash on DLL_attach. It starts fine, and the text to speech engine gets initialized, but I can't access ISpVoice outside the thread. How can I access ISpVoice outside the thread ? It's a global variable after all...

#include <windows.h>
#include <sapi.h>
#include "XPThreads.h"


ISpVoice * pVoice = NULL;

unsigned long init_engine_thread(void* param)
{
Sleep(5000);
    printf("lolthread\n");



    //HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);
    HRESULT hr = CoInitialize(NULL);

    if(FAILED(hr) )
    {
        MessageBox(NULL, TEXT("Failed To Initialize"), TEXT("Error"), 0);
        char buffer[2000] ;
        sprintf(buffer, "An error occured: 0x%08X.\n", hr);
        FILE * pFile = fopen ( "c:\\temp\\CoInitialize_dll.txt" , "w" );
        fwrite (buffer , 1 , strlen(buffer) , pFile );
        fclose (pFile);
    }
    else
    {   
        printf("trying to create instance.\n");
        //HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice);
        //hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice);
        //HRESULT hr = CoCreateInstance(__uuidof(ISpVoice), NULL, CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **) &pVoice);
        HRESULT hr = CoCreateInstance(__uuidof(SpVoice), NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice);
        if( SUCCEEDED( hr ) )
        {
            printf("Succeeded\n");
            hr = pVoice->Speak(L"The text to speech engine has been successfully initialized.", 0, NULL);
        }
        else
        {
            printf("failed\n");
            MessageBox(NULL, TEXT("Failed To Create COM instance"), TEXT("Error"), 0);
            char buffer[2000] ;
            sprintf(buffer, "An error occured: 0x%08X.\n", hr);

            fclose (pFile);
        }
    }



    if(pVoice != NULL)
    {
        pVoice->Release();
        pVoice = NULL;
    }
    CoUninitialize();


return NULL;
