    <p><strong>FIRST OF ALL:</strong></p> <p>You don't want to do that. </p> <p>Exceptions are not meant for handling <em>bugs</em>, but run-time error conditions that make it impossible for your function to satisfy the pre-conditions of other functions it has to call, or to keep the promise of fulfilling its own post-conditions (given that the caller has satisfied the pre-conditions). See, for instance, <a href="http://www.drdobbs.com/when-and-how-to-use-exceptions/184401836" rel="nofollow">this article by Herb Sutter</a>.</p> <p>Don't ever write anything like this:</p> <pre><code>try { //bug condition &lt;== NO! Exceptions are not meant to handle bugs } catch() { //Remove file } </code></pre> <p>But rather:</p> <pre><code>assert( /* bug condition... */ ); </code></pre> <p><strong>BACK TO THE QUESTION:</strong></p> <p>Your program has undefined behavior, and most likely it will not throw any exception at all when you do:</p> <pre><code>char TempArray[10]; char c = TempArray[11]; </code></pre> <p>So catching all exceptions won't help. This is a bug, i.e. a <em>programming</em> error, and it is arguable whether you should handle bugs in a way that transfer controls to a buggy routine; moreover, if you are admitting the presence of bugs in your program, couldn't you just be transferring control to a buggy handler? That may make it even worse.</p> <p>Bugs should be dealt with by <em>preventing</em> them, making use of assertions, perhaps adopting methodologies such as test-driven development, and so on.</p> <p>This said, regarding a way to catch all exceptions, you can do:</p> <pre><code>try { // ... } catch (...) // &lt;== THIS WILL CATCH ANY EXCEPTION { } </code></pre> <p>But using <code>catch (...)</code> is discouraged as a design guideline, because it easily leads to swallow error conditions that are meant to be handled and forget about them. After all, exceptions were invented exactly to prevent programmers to forget checking error codes, and <code>catch (...)</code> makes that so easy.</p> <p>For a catch-everything purpose, it would be better to let all of your exceptions derive from <code>std::exception</code>, and then do:</p> <pre><code>try { // ... } catch (std::exception&amp; e) { // Do something with e... } </code></pre>

    1. CO*"But that is regarded as bad programming style"*. Just because a mechanism can be abused doesn't make it bad programming style by definition. There are many valid use cases for `catch(...)`, it's only bad if you use it to blindly hide problems that shouldn't be hidden.

    3. CO@Niels: Well, while there may be valid uses (as there may be valid uses of `using namespace std`), abusing it is easier than not. And a `catch (...)` just makes it easier to forget about error conditions

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.
