    <p>I'm currently working in a C++ project which has to be able to read emails from an gmail POP3 account just like the title says. Also is important to say that I need to download the attachments (is encode base64?) of the mail and its body. The fact is that everyone recommend to use libCurl for this task, but the code sample on their web is not working. I saw this example on <a href="http://curl.haxx.se/libcurl/c/pop3s.html" rel="nofollow noreferrer">Libcurl website</a>:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;curl/curl.h&gt; int main(void) { CURL *curl; CURLcode res; curl = curl_easy_init(); if(curl) { /* Set username and password */ curl_easy_setopt(curl, CURLOPT_USERPWD, "user:password"); /* This will only fetch the message with ID "1" of the given mailbox */ curl_easy_setopt(curl, CURLOPT_URL, "pop3s://user@pop.example.com/1"); /* Perform the request, res will get the return code */ res = curl_easy_perform(curl); /* Check for errors */ if(res != CURLE_OK) fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res)); /* always cleanup */ curl_easy_cleanup(curl); } return 0; } </code></pre> <p>As you see, the code looks pretty easy for fetching email by email inside the inbox, but when i try to perform the operation with <strong>CURLcode curl_easy_perform(CURL *)</strong> the function doesn't return anything and the process 'dies' so i can't skip this line. My code is the following one:</p> <pre><code>void MailServer::Open(char *username,char *password) { m_username = username; //username = example@gmail.com m_password = password; //password = blabla123 curl = curl_easy_init(); curl_easy_setopt(curl,CURLOPT_USERNAME,username); curl_easy_setopt(curl,CURLOPT_PASSWORD,password); m_popsAccount = "pop3s://" + m_username +"/1"; curl_easy_setopt(curl, CURLOPT_URL, m_popsAccount.c_str()); res = curl_easy_perform(curl); //here does not return anything } </code></pre> <p>I tried to find some 'clear' example on the web, but i really couldn't... Someone could give me a hand with it? :)</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.
