    <p>For creating a directory you can use the C function:</p> <pre><code>int mkdir(const char *pathname, mode_t mode); </code></pre> <p>If you can use <a href="http://www.boost.org/" rel="nofollow">Boost</a>, then it really becomes easier and more C++ friendly:</p> <pre><code>bool create_directories(const path&amp; p); // usage example boost::filesystem::create_directories("./BobtheBuilder"); </code></pre> <p>As you mention in your question , you can use both absolute and relative paths. It just depends on what is your intention. In your case, you could just do:</p> <pre><code>boost::filesystem::create_directories("./BobtheBuilder"); ofstream out("./BobtheBuilder/NewFile.txt"); </code></pre> <p>not needing to specify the absolute path at all.</p> <p>If you often need to manage paths, Boost provides many useful tools for path management. Just as an example, consider the problem you mention in your question: you want to get the full path to the current directory and then append a relative path. You could do this very easily:</p> <pre><code> #include &lt;boost/filesystem.hpp&gt; namespace fs = boost::filesystem; ... fs::path curr_abs_path = fs::current_path(); fs::path rel_path = "foo/bar"; fs::path combined = (curr_abs_path /= rel_path); cout &lt;&lt; combined &lt;&lt; endl; </code></pre> <p>Assuming the current directory is /tmp/ the previous code snippet would print:</p> <blockquote> <p>/tmp/foo/bar</p> </blockquote> <p><code>operator/=</code> is responsible for appending two paths and returning the combined result.</p>

    1. POHow do you create a folder in C++ with no path name just the name of the folder you want to create?

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.
