Body
Section of my code where error is occuring: <pre><code>int disk::access (const char fname[]){ int char_count=77; int actual_count=0; //just to pass the tests. char c; cout << "the file name is " << fname << ", and the mode is " << mode << endl; if(strcmp(mode, "w")==0){ for (int i = 0; i < size; i++) { //cout << "sgm to be written is " << sgm[i]; fp=fopen(fname, "w"); fprintf(fp, "%s\n",sgm[i]); } fclose(fp); } if(strcmp(mode,"a")==0){ fp=fopen(fname, "a"); fprintf(fp, "%s\n", sgm); fclose(fp); } fp=fopen(fname, "r"); do{ c=fgetc(fp); if(c!=' ' && c!='\n') actual_count++; }while(c!=EOF); fclose(fp); return actual_count; } </code></pre> my error: <blockquote> disk.cpp: In member function 'int disk::access(const char*)': disk.cpp:67: warning: cannot pass objects of non-POD type 'class segment' through '...'; call will abort at runtime </blockquote> EDIT line 67 is: fprintf(fp, "%s\n",sgm[i]); EDIT SGM: the cpp code: <pre><code>disk::disk(int num_of_segments, const char* temp_mode){ size=num_of_segments; sgm = new segment[size]; //initializes num_of_segments in a disk count=0; if(strcmp(mode, "w")!=0||strcmp(mode, "a")!=0){ strcpy(mode, "w"); } } disk::disk(){ sgm = new segment[20]; //initialize 20 segments in a disk size=20; //keeps track of how many are initialized count=0; //keeps track of how many are added strcpy(mode, "w"); //initialize disk access mode to w } </code></pre> the header code: <pre><code>class disk { private: int size, count; //to keep a track of number of segments char mode [2]; //a for append and w for write segment* sgm; FILE *fp; public: disk(int num_of_segments, const char *temp_mode); disk(); ~disk(); const char* get_mode( ) const; segment get_segment(int pos) const; int get_segment_count( ) const; const segment* get_all_segments( ) const; int access(const char fname[ ]); disk& operator+=(const segment &rhs); disk& operator=(const disk &dk); }; </code></pre> I haven't come across a warning like this before. I did some searching and from what I gathered POD is "plain old data that is a struct without constructors, destructors and virtual members functions." -Greg Hewgill So if I understood that correctly, my error is that I do have constructors or destructors and or virtual member functions because it is non-POD? I think I'm just confusing myself, I'm not sure how to go about fixing this error or even pinpointing where the problem is occuring. All suggestions are welcome and greatly appreciated, thanks.

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.
