searchPublicChat sometimes has not callback, why?

[liaoxingquan]

HANDLE hEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
td_api::object_ptr<td_api::chat> chat;
send_query(td_api::make_object<td_api::searchPublicChat>(query),
    [this, &chat, hEvent](Object object) {
    if (object->get_id() == td_api::error::ID) {
        SendErrorMsg(object);
        SetEvent(hEvent);
        return;
    }
    chat = td::move_tl_object_as<td_api::chat>(object);
    SetEvent(hEvent);
});
WaitForSingleObject(hEvent_, INFINITE);
CloseHandle(hEvent);
    return chat;

If there is no callback, my process is not return I don't know why

[levlam]

All requests return result after they are completed. The issue can be in the SendErrorMsg function, or with the network access. You need to check TDLib logs for details.

SendErrorMsg this is my function, I interrupted a bit, process has not going there, but my process is MFC project, how to check TDLib logs

[liaoxingquan]

I don't know which function is output logs

[levlam]

You can use setLogStream method to set up logging.

ok , I try it

[liaoxingquan]

searchPublicChat also has no callback, have no loging info

[liaoxingquan]

There is only some successful login information in the log

If there is no searchPublicChat request in the log with verbosity level >= 3, then the request wasn't sent.
