    <p>I'm having an issue with istringstream not storing the values it reads. Here is what I have:</p> <pre><code> if(inputFile.good()){ //Make sure file is open before trying to work with it //Begin Working with information cout &lt;&lt; "\tIn File: " &lt;&lt; input &lt;&lt; endl; cout &lt;&lt; "------------------------------------" &lt;&lt; endl; int number_of_lines = 0; std::string line; while (std::getline(inputFile, line)){ ++number_of_lines; } Time times[number_of_lines]; double math[number_of_lines]; std::string input; int hh, mm; for(int loop=0;loop&lt;number_of_lines;loop++){ std::getline(inputFile, input); std::istringstream(input) &gt;&gt; mm &gt;&gt; hh &gt;&gt; math[loop]; cout &lt;&lt; "hours = " &lt;&lt; hh &lt;&lt; endl; times[loop].setTimeHours(hh); times[loop].setTimeMinutes(mm); times[loop].show(); cout &lt;&lt; "*" &lt;&lt; math[loop] &lt;&lt; endl; } std::cout &lt;&lt; "Number of lines in text file: " &lt;&lt; number_of_lines &lt;&lt; "\n" &lt;&lt; endl; }else{ cout &lt;&lt; "Could not open file!!!" &lt;&lt; endl; } </code></pre> <p>The file I'm reading looks like this:</p> <pre><code>90 1 3.0 1 1 100.0 2 34 5.1 </code></pre> <p>And the output when I run:</p> <pre><code> In File: data04.txt ------------------------------------ hours = 0 Operation To Be Done = 0:2336552*1.15384e-317 hours = 0 Operation To Be Done = 0:2336552*1.58101e-322 hours = 0 Operation To Be Done = 0:2336552*1.15397e-317 Number of lines in text file: 3 </code></pre> <p>Anyone know why its not storing the values?</p>

    1. CODid you check that the read operations were successful? (just a rhetorical question which is answered by the code, of course)

    2. COWell I just did a `cout << input << endl;` to make sure input had stuff in it but it printed a blank line, so something isn't working right! lol

    3. COYes. This does't count as verifying that input was successful. Something like `if (std::getline(inputFile, line))` or `while (std::getline(inputFile, line))` or `if (std::istringstream(intput) >> mm >> hh)` would count as verifying.

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.
