    <p>I want to perform a batch replace operation on a project by following some rules. For e.g. I am taking notes in the code like this:</p> <p>On every code piece, which is commented like this, I want to perform a replace operation, which will replace the input code piece with the output code piece in the following examples:</p> <p><strong>Input 1:</strong></p> <pre><code>//+ a++; //+(+SomeException$SomeMessage) </code></pre> <p><strong>Output 1:</strong></p> <pre><code>try { a++; } catch (AnException) { throw; } catch (Exception ex) { throw new SomeException("SomeMessage", "15", ex); } </code></pre> <p><strong>Input 2:</strong></p> <pre><code>//+ a++; //-(+InvalidOperationException$SomeMessage) </code></pre> <p><strong>Output 2:</strong></p> <pre><code>try { a++; } catch (InvalidOperationException ex) { throw new AnException("SomeMessage", "16", ex); } </code></pre> <p><strong>Input 3:</strong></p> <pre><code>//+ a++; //-(SomeMessage) </code></pre> <p><strong>Output 3:</strong></p> <pre><code>try { a++; } catch (Exception ex) { throw new AnException("SomeMessage", "17", ex); } </code></pre> <p>The magic numbers (15, 16, 17) will increase for each code piece commented like this. I know this is not the best practice but I am not making the decisions and I am expected to handle exceptions like this, so I thought I can ease the pain by taking notes and batch replacing in the end. What is the best way to do this? Should I write my own code to perform replaces or is there some regex replace tool or something like that exist that can automatically make this for me?</p> <p><strong>Update:</strong> This is a one time job and my magic number has to be globally unique. So if it was 25 for the last match in a file, it must be 26 for the first match in the next file.</p>

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.
