    <p>I have an issue with the recursive call in the walkThroughFunction. The code is supposed to go through directories and count the sub directories and if it finds a file it should open it and search a certain string. The code only goes through one directory. Can someone help me with this. You will find the braces misplaced a little. Kindly ignore those.</p> <pre><code>int directories=0; void walkThroughDirectory(char *directory_name,char *searchString){ DIR * directory; struct dirent * walker; char d_name[PATH_MAX]; int path_length; char path[PATH_MAX]; directory=opendir(directory_name); if(directory==NULL){ cout&lt;&lt;"Error"&lt;&lt;endl; cout&lt;&lt;directory_name&lt;&lt;" Cannot be Opened"&lt;&lt;endl; exit(10000); } while((walker=readdir(directory)) !=NULL){ strcpy(d_name,walker-&gt;d_name); cout&lt;&lt;directory_name&lt;&lt;"/"&lt;&lt;endl; if (strcmp (d_name, "..") == 0 &amp;&amp; strcmp (d_name, ".") == 0){ continue; } else{ path_length = snprintf(path,PATH_MAX,"%s/%s\n",directory_name,d_name); cout&lt;&lt;"HELLO"&lt;&lt;endl; cout&lt;&lt;path&lt;&lt;endl; if (path_length &gt;= PATH_MAX){ cout&lt;&lt;"Path is too long"&lt;&lt;endl; exit (1000); } if(walker-&gt;d_type==DT_DIR){ cout&lt;&lt;"Hello"&lt;&lt;endl; directories++; walkThroughDirectory (path,searchString); } else if(walker-&gt;d_type==DT_REG){ ifstream openFile; openFile.open(path); char line[1500]; int currentLine = 0; if (openFile.is_open()){ while (openFile.good()){ currentLine++; openFile.getline(line, 1500); if (strstr(line, searchString) != NULL) cout&lt;&lt;path&lt;&lt;": "&lt;&lt;currentLine&lt;&lt;": "&lt;&lt;line&lt;&lt;endl; } } openFile.close(); } /* struct stat directory_stat; if (stat(path, &amp;directory_stat) == -1){ return; } if (S_ISDIR(directory_stat.st_mode)){ cout&lt;&lt;"HELLO"&lt;&lt;endl; directories++; walkThroughDirectory(path, searchString); } else if (S_ISREG(directory_stat.st_mode)){ ifstream openFile; openFile.open(path); char line[1500]; int currentLine = 0; if (openFile.is_open()){ while (openFile.good()){ currentLine++; openFile.getline(line, 1500); if (strstr(line, searchString) != NULL) cout&lt;&lt;path&lt;&lt;": "&lt;&lt;currentLine&lt;&lt;": "&lt;&lt;line&lt;&lt;endl; } } // it's a file so search for text in file } */ } } if (closedir (directory)) { cout&lt;&lt;"Unable to close "&lt;&lt;directory_name&lt;&lt;endl; exit (1000); } } int main(){ char * name; name=new char; cout&lt;&lt;"Total Directories "&lt;&lt; directories&lt;&lt;endl; name=get_current_dir_name(); cout&lt;&lt;"Current Directory is: "&lt;&lt;name&lt;&lt;endl; /* cout&lt;&lt;"Now Enter The Desired Directory from the root or the current path"&lt;&lt;endl; char *desiredDirectory; desiredDirectory=new char; cin&gt;&gt;desiredDirectory; cout&lt;&lt;"Enter The String You want to search"&lt;&lt;endl; char *searchString; searchString=new char; cin&gt;&gt;searchString; */ char ourpath[400]; strcpy(ourpath,name); walkThroughDirectory(ourpath,"diminutive"); cout&lt;&lt;"Total Directories "&lt;&lt; directories&lt;&lt;endl; return 0; } </code></pre>

    1. COWhy _are_ your braces misplaced? You will be able to fix a lot of errors a lot more quickly if you use a proper indentation scheme.

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.
