    <p>I'm trying to make a function to split a string, "Split At Spaces", into a vector which would contain "Split" "At" "Spaces". So far, this is the code I've got.</p> <pre><code>#include &lt;iostream&gt; #include &lt;utility&gt; #include &lt;algorithm&gt; using namespace std; std::vector&lt;std::string&gt; split(std::string * s, char * tosplit) { size_t i = 0; int count = 0; size_t contain; std::vector&lt;std::string&gt; split; std::cout &lt;&lt; "Start" &lt;&lt; std::endl; std::cout &lt;&lt; *s &lt;&lt; std::endl; std::cout &lt;&lt; *tosplit &lt;&lt; std::endl; while((contain = s-&gt;find(*tosplit,i)) != std::string::npos) { count++; i = contain + 1; } std::cout &lt;&lt; "Contains " &lt;&lt; count &lt;&lt; std::endl; if (count == 0) { std::cout &lt;&lt; "Equals 0" &lt;&lt; std::endl; split = std::vector&lt;std::string&gt;(1); split.at(0) = s-&gt;c_str(); return split; } split = std::vector&lt;std::string&gt;(count + 1); split.begin(); int lasti; i = s-&gt;find_first_of(*tosplit); split.at(0) = s-&gt;substr(0, i); lasti = i; int runs = 1; while (runs &lt;= count) { i = s-&gt;find(*tosplit, lasti + 1); std::cout &lt;&lt; i &lt;&lt; " " &lt;&lt; lasti &lt;&lt; std::endl; split.at(runs) = s-&gt;substr(lasti, --i); runs++; lasti = i; } split.at(runs) = s-&gt;substr(lasti, s-&gt;size()); std::cout &lt;&lt; "done, result is" &lt;&lt; std::endl; i = 0; while (i &lt; split.capacity()) { std::cout &lt;&lt; split.at(i) &lt;&lt; std::endl; i++; } return split; } </code></pre> <p>It throws an out_of_range exception. Any help you can give would be appreciated. This is like my first part using pointers in a function so I'm kinda guessing here.<br> Thanks!</p> <p>Please don't suggest using x or y method, <strong>I'd like to write my own</strong> as I'm doing it for the experience.</p>

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.
