Then, after you establish the connection with the server, you need to advise your implementation of the
event interface:
IVScriptEngine vscript_engine = NULL;
try
{ vscript_engine = vscript ->GetVScriptEngine( "Test_1" ); }
catch ( _com_error& er )
{ SetStatusError( er ); }
if( vscript_engine == NULL )
{
vscript = NULL;
return E_FAIL;
}
CVSEngineSink vse_sink;
HRESULT hr = vse_sink . Advise( vscript_engine ); // “Subscribe” for receiving events
...
VS_RESULT res = SCRIPT_NOT_FOUND;
try
{
res = (VS_RESULT)vscript_engine ->RunVScript();
}
catch ( _com_error& er)
{ SetStatusError( er ); }
// Tear connection with the test case.
vse_sink. Unadvise( vscript_engine );
