I'm trying to read till the end of a file for a phonebook app that im converting from C to C++. When I print the the results from the file i get this: <pre><code>johnny smith (Home)3 (Cell)4 x☺> x☺> (Home)4 (Cell)4 </code></pre> it should print: <pre><code>johnny smith (Home)3 (Cell)4 </code></pre> Right now I'm using <code>while(!infile.eof())</code> which i've read is a poor practice, but when I use <code>infile.getline()</code> I get a repeat of the first and last name, and the format is all jacked up. Is there anyway(or another way) to get rid of the junk at the end of the input or another way to read till the end of file in C++ that fixes this. I've been reading about different solutions, but the one a lot of sites seem to agree on is <code>fgets</code>, which is what I had with the original C version, but obviously <code>fgets</code> doesn't work with <code>ifstream</code> which is what I'm using. here is the code: <pre><code>void contacts:: readfile(contacts*friends ,int* counter, int i,char buffer[],char user_entry3[]) { ifstream read; read.open(user_entry3,ios::in); int len; contacts temp; *counter=0; i=0; while (!read.eof()) { temp.First_Name=(char*)malloc(36); temp.Last_Name=(char*)malloc(36); read>>temp.First_Name>>temp.Last_Name; read>>buffer; len=strlen(buffer); if(buffer[len-1]=='\n') buffer[len-1]='\0'; temp.home=(char*)malloc(20); strcpy(temp.home, buffer); read>>buffer; len=strlen(buffer); if(buffer[len-1]=='\n') buffer[len-1]='\0'; temp.cell=(char*)malloc(20); strcpy(temp.cell, buffer); friends[i].First_Name=(char*)malloc(MAXNAME); friends[i].Last_Name=(char*)malloc(MAXNAME); friends[i].home=(char*)malloc(MAXPHONE); friends[i].cell=(char*)malloc(MAXPHONE); //adds file content to the structure strcpy(friends[*counter].First_Name,temp.First_Name); strcpy(friends[*counter].Last_Name,temp.Last_Name); strcpy(friends[*counter].home,temp.home); strcpy(friends[*counter].cell,temp.cell); (*counter)++; i++; } //closes file and frees memory read.close(); free(temp.Last_Name); free(temp.First_Name); free(temp.home); free(temp.cell); } </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.
