    <p>I have a program which takes in multiple command line arguments so I am using getopt. One of my arguments takes in a string as a parameter. Is there anyway to obtain that string through the getopt function or would I have to obtain it through the argv[] array? Also can getopt read args like <code>-file</code> ? All the arguments I have seen till now have only one character such as <code>-a</code></p> <p><strong>EDIT</strong></p> <p>From the below answers I have written a program to use getopt_long(), but the switch statement only recognizes the argument when I use the character argument and not the long argument. I'm not sure why this happening. On passing the arguments <code>-mf -file sample</code> I do not see the print statements.</p> <p><strong>EDIT</strong></p> <p>I tried entering the command arguments as <code>--file</code> and then it worked. Is it not possible to do this with just <code>-file</code> ? </p> <pre><code>static struct option long_options[] = { {"mf", required_argument, NULL, 'a'}, {"md", required_argument, NULL, 'b'}, {"mn", required_argument, NULL, 'c'}, {"mw", required_argument, NULL, 'd'}, {"lf", required_argument, NULL, 'e'}, {"ld", required_argument, NULL, 'f'}, {"ln", required_argument, NULL, 'g'}, {"lw", required_argument, NULL, 'h'}, {"rf", required_argument, NULL, 'i'}, {"rd", required_argument, NULL, 'j'}, {"rn", required_argument, NULL, 'k'}, {"rw", required_argument, NULL, 'l'}, {"df", required_argument, NULL, 'm'}, {"dd", required_argument, NULL, 'n'}, {"dn", required_argument, NULL, 'o'}, {"dw", required_argument, NULL, 'p'}, {"file", required_argument, NULL, 'q'}, {NULL, 0, NULL, 0} }; int ch=0; while ((ch = getopt_long(argc, argv, "abcdefghijklmnopq:", long_options, NULL)) != -1) { // check to see if a single character or long option came through switch (ch){ case 'a': cout&lt;&lt;"title"; break; case 'b': break; case 'c': break; case 'd': break; case 'e': break; case 'f': break; case 'g': break; case 'h': break; case 'i': break; case 'j': break; case 'k': break; case 'l': break; case 'm': break; case 'n': break; case 'o': break; case 'p': break; case 'q': cout&lt;&lt;"file"; break; case '?': cout&lt;&lt;"wrong message" break; } } </code></pre>

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.
