    <p>I'm having the weirdest problem causing me headaches. Consider the following code:</p> <pre><code>// Create and bind socket std::map&lt;Connection, bool&gt; clients; unsigned short port=6222; struct sockaddr_in local_address, from_address; int result; char buffer[10000]; SOCKET receive_socket; local_address.sin_family = AF_INET; local_address.sin_addr.s_addr = INADDR_ANY; local_address.sin_port = htons(port); receive_socket = socket(AF_INET,SOCK_DGRAM,0); </code></pre> <p>What's happening is receive_socket is not binding, I get SOCKET_ERROR. When I debug the program and check receive_socket, it appears to just be garbled crap. I put a breakpoint on the 'std::map' line. When I step into each line of the above code, the debug cursor jumps straight from the 'unsigned short port' line to the first 'local_address.sin' line, even though I am using step into (F11), it does not stop at struct, int, char or SOCKET lines, it jumps straight over them. </p> <p>At this point I hover my mouse over local_address, from_address, result, buffer and receive_socket. They are all full of garbled crap. Is this because I have not defined these variables yet? I've also noticed that when I reach the bottom of the above code, local_address.sin_port is set to 19992, but it should be 6222?</p> <p>Edit: here is my binding code which is failing because the if statement is true:</p> <pre><code>if(bind( receive_socket, (SOCKADDR*) &amp;local_address, sizeof(local_address)) == SOCKET_ERROR) { closesocket(receive_socket); return 1; } </code></pre>

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.
