    <p>Fopen and Fclose are wrapper functions in my source file that check for errors when opening the file. when I run my program, it says there was an Fopen error. I see no reason for an error during the file opening.</p> <p>Sorry for the long code. </p> <pre><code>#include &lt;stdio.h&gt; #include &lt;ctype.h&gt; #include &lt;stdlib.h&gt; #include &lt;string.h&gt; #include "perry.h" int main(void) { void copyStrings(char *infile, char *outfile, char ch); void compareFiles(char *infile, char *outfile); char inputfile[80]; char outputfile[80]; char ch; printf("Enter input filename: "); scanf("%s", inputfile); printf("Enter output filename: "); scanf("%s", outputfile); printf("Enter a character: "); scanf(" %c", &amp;ch); if(!isalpha(ch)) { printf("Did not enter a letter!"); exit(1); } copyStrings(inputfile, outputfile, ch); compareFiles(inputfile, outputfile); return 0; } void copyStrings(char *infile, char *outfile, char ch) { int count; char *ptr; char *line; char linePart[80]; FILE *fin; FILE *fout; fin = Fopen(infile, "r"); fout = Fopen(outfile, "w"); while(fgets(line, 80, fin) != NULL) { for(ptr=line;ptr&lt;line+strlen(line);ptr++) { if(*ptr == ch) count ++; } if(count &lt; 2) fputs(line, fout); else { memset(linePart, '\0', strlen(line)+1); line = strchr(line, ch); strncpy(linePart, line, strchr(line+1, ch) - line + 1); fputs(linePart, fout); fprintf(fout, "\n"); } } Fclose(fout); Fclose(fin); return; } void compareFiles(char *infile, char *outfile) { int count = 0; char inputString[80]; char outputString[80]; FILE *fin; FILE *fout; fin = Fopen(infile, "r"); fout = Fopen(outfile, "r"); while(fgets(inputString, 80, fin) != NULL) { count += 1; if(strcmp(inputString, fgets(outputString, 80, fout)) == 0) { printf("Strings are equal at line %d\n\nBoth strings look like this: %s", count, inputString); } } Fclose(fout); Fclose(fin); return; } </code></pre>

    1. COSeeing the actual code for `Fopen` would go a long way into answering this question.

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.
