    <p>I wrote a complete program that includes all the things you mentioned above I did change the way the file was read in slightly - I'm not familiar with the way you call getline() where the first parameter is the stream name, so I created a character buffer to read in the individual elements, then copy them to the pair. I also make sure I don't do something crazy at the end of the file, in case there are not two elements read (it works whether there's a \n at the end of file, or not).</p> <pre><code>#include &lt;fstream&gt; #include &lt;iostream&gt; #include &lt;list&gt; #define BUF 100 using namespace std; int main() { std::ifstream myReadFile; std::list&lt;std::pair&lt;std::string,std::string&gt; &gt; startTape; std::pair&lt;std::string,std::string&gt; pair; char sbuf[BUF]; // temp storage for file read myReadFile.open("listOwords.txt"); if(!myReadFile) { cerr &lt;&lt; "Error: file could not be opened" &lt;&lt; endl; exit(1); } cout &lt;&lt; "file opened successfully" &lt;&lt; endl; while(myReadFile.getline(sbuf, BUF, ',')) { pair.first = sbuf; myReadFile.getline(sbuf, BUF); pair.second = sbuf; if(myReadFile.good()) { // only process if both elements were read successfully // this deals with the problem of a "half pair" being read if the file is terminated with \n startTape.push_back(pair); cout &lt;&lt; "read a pair: " &lt;&lt; pair.first &lt;&lt; ", " &lt;&lt; pair.second &lt;&lt; endl; } } myReadFile.close(); cout &lt;&lt; "Size of startTape is now " &lt;&lt; startTape.size() &lt;&lt; endl; std::pair&lt;std::string,std::string&gt; firstCompare = startTape.front(); startTape.remove(*startTape.begin()); cout &lt;&lt; "Size of startTape is now " &lt;&lt; startTape.size() &lt;&lt; endl; std::pair&lt;std::string,std::string&gt; secondCompare = startTape.front(); startTape.remove(*startTape.begin()); cout &lt;&lt; "Size of startTape is now " &lt;&lt; startTape.size() &lt;&lt; endl; exit(0); } </code></pre> <p>The contents of listOwords:</p> <pre><code>&gt;cat listOwords.txt N, C I, G A, U H, A G, M C, I S, H U, N </code></pre> <p>The output I get from this is:</p> <pre><code>file opened successfully read a pair: N, C read a pair: I, G read a pair: A, U read a pair: H, A read a pair: G, M read a pair: C, I read a pair: S, H read a pair: U, N Size of startTape is now 8 Size of startTape is now 7 Size of startTape is now 6 </code></pre> <p>Let me know if you don't get the same results with this exact code?</p>

    1. COI get exactly the same as you, I'm not sure why the error appears on my other code. But this is a great way of doing it. Thank you

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.
