    <p>Okay, so I'm trying to create a list of he folders, and sub-folders and their files, but right now it doesn't print anything, and seems to be going into an infinite loop. Any idea why?</p> <pre><code> //infinate loop start for(int j = 0; j &lt; (int) dirs[i].folders.size(); j++){ dirs.push_back(Directory(dirs[i].folders[j])); getfiles(dirs[i].dir,dirs[i].files); getfolders(dirs[i].dir,dirs[i].folders); } //infinate loop end </code></pre> <p>Here is the full source:</p> <pre><code>#include &lt;sys/types.h&gt; #include &lt;sys/stat.h&gt; #include &lt;dirent.h&gt; #include &lt;errno.h&gt; #include &lt;vector&gt; #include &lt;string&gt; #include &lt;iostream&gt; using namespace std; struct Directory{ public: int indent; vector&lt;string&gt; files; vector&lt;string&gt; folders; string dir; Directory(string mydir){ dir = mydir;} }; int getfolders (string dir, vector&lt;string&gt; &amp;folders) { DIR *dp; struct stat st; struct dirent *dirp; if((dp = opendir(dir.c_str())) == NULL) { cout &lt;&lt; "Error(" &lt;&lt; errno &lt;&lt; ") opening " &lt;&lt; dir &lt;&lt; endl; return errno; } while ((dirp = readdir(dp)) != NULL) { stat(dirp-&gt;d_name, &amp;st); if(S_ISDIR(st.st_mode)){ if(dirp-&gt;d_name[0] != '.') folders.push_back(string(dirp-&gt;d_name)); } } closedir(dp); return 0; } /*function... might want it in some class?*/ int getfiles (string dir, vector&lt;string&gt; &amp;files) { DIR *dp; struct stat st; struct dirent *dirp; if((dp = opendir(dir.c_str())) == NULL) { cout &lt;&lt; "Error(" &lt;&lt; errno &lt;&lt; ") opening " &lt;&lt; dir &lt;&lt; endl; return errno; } while ((dirp = readdir(dp)) != NULL) { stat(dirp-&gt;d_name, &amp;st); if(!S_ISDIR(st.st_mode)){ files.push_back(string(dirp-&gt;d_name)); } } closedir(dp); return 0; } int main() { struct Directory root = Directory("."); vector&lt;string&gt; display = vector&lt;string&gt;(); cout &lt;&lt; "hello\n"; getfiles(root.dir,root.files); getfolders(root.dir,root.folders); cout &lt;&lt; "hello\n"; vector&lt;Directory&gt; dirs = vector&lt;Directory&gt;(); for(int i = 0; i &lt; (int) root.folders.size(); i++){ dirs.push_back(Directory(root.folders[i])); getfiles(dirs[i].dir,dirs[i].files); getfolders(dirs[i].dir,dirs[i].folders); //infinate loop start for(int j = 0; j &lt; (int) dirs[i].folders.size(); j++){ dirs.push_back(Directory(dirs[i].folders[j])); getfiles(dirs[i].dir,dirs[i].files); getfolders(dirs[i].dir,dirs[i].folders); } //infinate loop end } cout &lt;&lt; "hello\n"; for (int i = 0; i &lt; (int) root.folders.size();i++) { cout &lt;&lt; root.folders[i] &lt;&lt; endl; for(int j = 0; j &lt; (int) dirs[i].folders.size(); j++){ cout &lt;&lt; dirs[i].folders[j] &lt;&lt; endl; } } return 0; } </code></pre>

    1. COThis is a question better answered by yourself and a debugger than a forum. You are using a debugger right!?

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.
