How ignore any exception in DEBUG

How ignore any exception in DEBUG_EVENT and continue?

I have a code in my service application that execute a determinated process on SYSTEM account and in debug mode via CreateProcessAsUser.

The trouble is that debugged process stop for example when Google Chrome is opened or debugged process executes a great number of tasks simultaneously.

I think that the main trouble is the lack of "ignore any exception in debug and continue"..

Any help or suggestion will welcome.

    int Stop = 0;

    DEBUG_EVENT DebugEv = { 0 };

    DWORD dwContinueStatus = DBG_CONTINUE;



    while (!Stop)

    {

        WaitForDebugEvent(&DebugEv, INFINITE);



        switch (DebugEv.dwDebugEventCode)

        {

        case EXCEPTION_DEBUG_EVENT:

            switch (DebugEv.u.Exception.ExceptionRecord.ExceptionCode)

            {

            case EXCEPTION_ACCESS_VIOLATION:

                break;

            case EXCEPTION_BREAKPOINT:

                break;

            case EXCEPTION_DATATYPE_MISALIGNMENT:

                break;

            case EXCEPTION_SINGLE_STEP:

                break;

            case DBG_CONTROL_C:

                break;

            default:

                break;

            }

        case CREATE_THREAD_DEBUG_EVENT:

            break;

        case CREATE_PROCESS_DEBUG_EVENT:

            if (DebugEv.u.CreateProcessInfo.hFile)

                CloseHandle(DebugEv.u.CreateProcessInfo.hFile);

            break;

        case EXIT_THREAD_DEBUG_EVENT:

            break;

        case EXIT_PROCESS_DEBUG_EVENT:

            Stop = 1;

            break;

        case LOAD_DLL_DEBUG_EVENT:

            if (DebugEv.u.LoadDll.hFile)

                CloseHandle(DebugEv.u.LoadDll.hFile);

            break;

        case UNLOAD_DLL_DEBUG_EVENT:

            break;

        case OUTPUT_DEBUG_STRING_EVENT:

            break;

        }



        ContinueDebugEvent(DebugEv.dwProcessId, DebugEv.dwThreadId, dwContinueStatus);

    }

you continue copy-paste the same wrong and very not efficient code. which here not related to your question

@RbMm, the part relative to CreateProcessAsUser() works fine, i posted in case someone want execute a complete code. The trouble is with the debug stretch.

if you not handle exception - you must return DBG_EXCEPTION_NOT_HANDLED
