    <p>I want to convert an Uint32 IP Address to a concatenated string.</p> <p>In the process of this i get uint8 data, but i need to change this to const char* to be able to concatenate it to other parts of the IP to be able to print the full IP in one variable.</p> <p>How can I change the uint 8 to const char*? Or is there a better way for all the process of conversion?</p> <pre><code>uint32 ipAddress = GetHostIp(); if (ipAddress) { const int NBYTES = 4; uint8 octet[NBYTES]; int x; char *ipAddressFinal; for (x = 0; x &lt; NBYTES; x++) { octet[x] = (ipAddress &gt;&gt; (x * 8)) &amp; (uint8)-1; } for (x = NBYTES - 1; x &gt;= 0; --x) { if (NBYTES==4) { const char *IPPart = octet[x]; // HERE IS THE BUG!!!!! ? strcpy(ipAddressFinal, IPPart); } else { const char *IPPart = octet[x]; // HERE IS THE BUG!!!!! ? strcat(ipAddressFinal, IPPart); } if (x &gt; 0) strcat(ipAddressFinal, "."); } LogAlways("IP: %s", ipAddressFinal); } </code></pre> <p><strong>Edit</strong></p> <p>Thanks guys - problem solved! Thanks to all! It's great to get very good answers in a short waiting time! Especially thanks to Lacrymology!!! Here is now working code, and I don't use Linux I should have wrote down my OS etc...</p> <pre><code>if (ipAddress) { const int NBYTES = 4; uint8 octet[NBYTES]; char ipAddressFinal[16]; for(int i = 0 ; i &lt; NBYTES ; i++) { octet[i] = ipAddress &gt;&gt; (i * 8); } sprintf(ipAddressFinal, "%d.%d.%d.%d", octet[3], octet[2], octet[1], octet[0]); LogAlways("IP: \"%s\"", ipAddressFinal); } </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.
