Body
As, the title says. I'm encountering redefinition errors due to including header files multiple times. I know its because of that, but I don't know how to resolve. Yes, I previously posted the same problem in SO an hour ahead. But I wasn't able to explain properly (I think so) and didn't get answers expected. Here is the link: <a href="https://stackoverflow.com/questions/1372480/c-redefinition-header-files">C++ Redefinition Header Files</a> I'm not editing that question since it has been filled up :). Okay I have some classes and the structure of them is like this: main.cpp: <pre><code>#include "Server.h" #include "Handler.h" #include "Processor.h" int main(int argc, char* argv[]) { } </code></pre> Server.h: <pre><code>// Server.h #pragma once #include <winsock2.h> </code></pre> Handler.h: <pre><code>// Handler.h #pragma once #include <string> #include <vector> #include "Server.h" </code></pre> Processor.cpp: <pre><code>// Processor.cpp #include "StdAfx.h" #include "Processor.h" #include "Handler.h" </code></pre> Server.cpp: <pre><code>// Server.cpp #include "Server.h" #include "Processor.h" </code></pre> The problem is that <code><winsock2.h></code> is included multiple times, don't know where but it is. #pragma once serves the same purpose as <pre><code>#ifndef SOME_FILE_H #define SOME_FILE_H // code here #endif // SOME_FILE_H </code></pre> in my compiler (MSVC2008 in this case). So I'm pretty much sure I don't need the header include guards. But can you spot where I'm doing the mistake by which <code><winsock2.></code> is included twice and how may I resolve? Thanks

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.
