    <p>So when I use this 'save' function, it seems to change the data within my structure, to random numbers and icons. If i don't save the file then the integrity of the data within the structure keeps true to the original input.</p> <p>I'm not sure where the error could be or how to even start to fixing this, thanks for any help.</p> <p>here is my structure;</p> <pre><code>struct packet{ // declare structure for packet creation int source; int destination; int type; int port; char data[51]; }; </code></pre> <p>here is the function;</p> <pre><code>//Save the records to a file: follows the same principle as list but uses a file handle (pointer to a file) //and fprintf to write to the file void save(int rCount, struct packet *records){ FILE *recordFile; //file handle char fileName[30] = { '\0'}; //string to store the file name int i; puts("Enter a filename to save the records :"); //ask the user for the filename scanf("%s", fileName); //store the filename: data input should be checked //here in your program //try and open the file for writing and react accordingly if there is a problem if((recordFile = fopen(fileName,"w"))==NULL){ printf("Couldn't open the file: %s\n",fileName); exit(1); } else{ //the file opened so print the records array of packet to it for(i=0;i&lt;rCount;i++){ fprintf(recordFile,"%04d:%04d:%04d:%04d:%s\n",records[i].source, records[i].destination, records[i].type, records[i].port, records[i].data); } fclose(recordFile); //close the file } } </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.
