    <p>My goal with my constructor is to:</p> <p>open a file read into everything that exists between a particular string ("%%%%%") put together each read row to a variable (history) add the final variable to a double pointer of type char (_stories) close the file.</p> <p>However, the program crashes when I'm using strcat. But I can't understand why, I have tried for many hours without result. :/</p> <p>Here is the constructor code:</p> <pre><code>Texthandler::Texthandler(string fileName, int number) : _fileName(fileName), _number(number) { char* history = new char[50]; _stories = new char*[_number + 1]; // rows for (int j = 0; j &lt; _number + 1; j++) { _stories[j] = new char [50]; } _readBuf = new char[10000]; ifstream file; int controlIndex = 0, whileIndex = 0, charCounter = 0; _storieIndex = 0; file.open("Historier.txt"); // filename while (file.getline(_readBuf, 10000)) { // The "%%%%%" shouldnt be added to my variables if (strcmp(_readBuf, "%%%%%") == 0) { controlIndex++; if (controlIndex &lt; 2) { continue; } } if (controlIndex == 1) { // Concatenate every line (_readBuf) to a complete history strcat(history, _readBuf); whileIndex++; } if (controlIndex == 2) { strcpy(_stories[_storieIndex], history); _storieIndex++; controlIndex = 1; whileIndex = 0; // Reset history variable history = new char[50]; } } file.close(); } </code></pre> <p>I have also tried with stringstream without results..</p> <p>Edit: Forgot to post the error message: "Unhandled exception at 0x6b6dd2e9 (msvcr100d.dll) in Step3_1.exe: 0xC00000005: Access violation writing location 0c20202d20." Then a file named "strcat.asm" opens..</p> <p>Best regards Robert</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.
