    <p>Firstly I should point out that this is my first stackoverflow question, so please bear with me.</p> <p>I'm having some problems overloading a function in c++. I'm trying to create a function with the following prototypes:</p> <pre><code>void push_at_command(std::string, std::vector&lt;std::string&gt;, int); void push_at_command(std::string, std::vector&lt;std::string&gt;, std::vector&lt;std::string&gt;, int); void push_at_command(std::string, std::vector&lt;std::string&gt;, std::vector&lt;std::string&gt;, std::vector&lt;std::string&gt;, int); void push_at_command(std::string, std::vector&lt;std::string&gt;, bool, int); </code></pre> <p>I originally wanted the last overload (the one with the boolean) to accept a boost::regex instead of a string vector;</p> <pre><code>void push_at_command(std::string, boost::regex, int); </code></pre> <p>but ran into ambiguity errors... so just to quickly get the code 'working' I thought I'd add a prototype to accept a flag, and use the first element in the vector to store a regex string, but I seem to be running into similar problems having the boolean.</p> <p>This is how I'm trying to call these various overloads:</p> <pre><code>push_at_command( "AT?S", boost::assign::list_of("(\\d{3}.\\d{3})"), true, 0); push_at_command( "AT?S", boost::assign::list_of("L11")("L12"), 0); push_at_command( "AT?S", boost::assign::list_of("L11"), boost::assign::list_of("L21")("L22"), 0); </code></pre> <p>And this is the error I'm getting:</p> <pre><code>error: call of overloaded ‘push_at_command(const char [5], boost::assign_detail::generic_list&lt;char [4]&gt;, boost::assign_detail::generic_list&lt;char [4]&gt;, int)’ is ambiguous note: candidates are: note: void push_at_command(std::string, std::vector&lt;std::basic_string&lt;char&gt; &gt;, std::vector&lt;std::basic_string&lt;char&gt; &gt;, int) note: void push_at_command(std::string, std::vector&lt;std::basic_string&lt;char&gt; &gt;, bool, int) </code></pre> <p>... which relates to the third function call.</p> <p>Just to note, I had no problems before I added the overload with the bool (or changing the string vector to regex).</p> <p>I am assuming the problem has something to do with me using boost::assign in the function call, and I realise that I don't need to, but I really need 'single line' function calls. ... Any advice welcome, as I am fairly new to C++.</p> <p>Thanks</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.
