    <p>I have a structure that contains, among other things, a couple of strings.</p> <pre><code>struct item { string item_name; int item_property_1; double item_property_2; } </code></pre> <p>Later I initialize them:</p> <pre><code>item item1; item1.item_name = "Name of Item"; item1.item_property_1 = 5; item1.item_property_2 = 10.0; </code></pre> <p>If I comment out the line assigning the string, it runs fine. With the string assignment, it crashes. I have no idea why.</p> <p>I have now commented out the contents of every other function trying to track down what could be causing the suggested corruption, and it still crashes. I'm down to one struct with a few strings and numbers, and if I assign a value to any of the strings it crashes.</p> <p>What could cause that corruption?</p> <p><em>edit</em> Adding in, by request, the smallest amount of real code that causes a crash. Commented out sections are omitted.</p> <pre><code>struct player_c { string advClass; int role; }; player_c shadow; Shadow::Shadow(QWidget *parent) : QMainWindow(parent), ui(new Ui::Shadow) { ui-&gt;setupUi(this); shadow.advClass = " "; shadow.role = 1; } </code></pre> <p>That's all that's left. I only included the int to test and verify that assigning it a value worked fine, and so long as the string is commented out it does. Any use of strings in the struct causes a crash.</p> <p>I don't NEED them there. I'm not currently using those strings, I put them in the struct because I intend to use them later, but I can accomplish the same purpose without them. Right now I just want to understand why.</p>

    3. COProbably the crash is **not** caused by that line, something else in your code wrote garbage on the _item1_ memory location.

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.
