Body
Since you request only first value in a string to be replaced (by using boost::format_first_only flag) original string <pre><code>"Mr $SURNAME$ from $LOCATION$" </code></pre> will be converted into <pre><code>"Mr ACTUAL_VAL from $LOCATION$" </code></pre> on first iteration and then <pre><code>" from ACTUAL_VAL" </code></pre> will be appended to it since you explicitly set begin to "what[0].second. so final output is <pre><code>"Mr ACTUAL_VAL from $LOCATION$ from ACTUAL_VAL" </code></pre> which is not what you need. Here is working example that has side effect - it modifies fileLine: <pre><code> const boost::regex expression( "\\$[\\w]+\\$" ); string fileLine( "Mr $SURNAME$ from $LOCATION$" ); string outLine; string::const_iterator begin = fileLine.begin(); string::const_iterator end = fileLine.end(); boost::match_results<string::const_iterator> what; boost::match_flag_type flags = boost::match_default; while ( regex_search( begin, end, what, expression, flags ) ) { const char* actualValue = valuesMap[what[0]]; ostringstream t( ios::out | ios::binary ); ostream_iterator<char, char> oi( t ); boost::regex_replace( oi, begin, end, expression, `enter code here`actualValue, boost::match_default | boost::format_first_only ); fileLine.assign(t.str()); begin = fileLine.begin(); end = fileLine.end(); } std::cout << fileLine << std::endl; </code></pre> If you don't want to modify fileLine, then you should make "begin" and "end" to mark the beginning and end of sliding window that contains exactly one pattern.

Guidance

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.
