Body
I've created to create a listener class that will call methods such as on_left_mouse_released on a controller object. It works fine, and now I am trying to have it run in another thread using boost::thread. However, I seem to be doing something wrong. I am new to multithreading, so this could easily be a simple error. Here are selected portions from the listener class: <pre><code>void Listener::listen() { keepListening = true; while(keepListening) { if(timerEnabled) { this->CheckForTimerEvent(); if( !PendingMouseOrKeyEvents()) //readconsoleinput is blocking continue; } if(!keepListening) //could have been changed in a timer event break; if(!mouseEnabled && !keyboardEnabled) continue; ReadConsoleInput(hIn, &InRec, 1, &NumRead); //see http://msdn.microsoft.com/en-us/library/windows/desktop/ms683499(v=vs.85).aspx //for more information on InRec and its submembers if(mouseEnabled &&InRec.EventType == MOUSE_EVENT) { this->ProcessMouseEvent(InRec.Event.MouseEvent); cout << "here"; } else if(keyboardEnabled && InRec.EventType == KEY_EVENT) { this->ProcessKeyEvent(InRec.Event.KeyEvent); cout << "here"; } } } void Listener::operator()() { listen(); } </code></pre> In my main function, if I create a Listener object named listener, then say "listener();" both of the couts occur with the appropriate events. However, if I use "boost::thread listen (boost::ref(listener));" instead, nothing happens. Does anyone see why this is?

1. COIs `ReadConsoleInput()` safe to call on a non-UI thread? A quick look of the documentation doesn't say either way, but that is the common gotcha with you start out writing multi-threaded software for Windows (or indeed MacOSX & iOS).

2. COThis sounds likely. What other kinds of things are limited like this? Could you recommend a link that talks about this?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
