    <p>Okay, so i have a huge file which i want to read in 1 Chapter at a time. a chapter is delimited by <code>'$'</code>. I am not really familiar with C++ just yet, so i made something that would read in a chapter as i would expect it to in C/C++.</p> <pre><code>#include &lt;nds.h&gt; #include &lt;stdio.h&gt; #include &lt;string&gt; #include &lt;vector&gt; #include &lt;sstream&gt; int dataFileLoc = 7; std::string fileReader(){ FILE * dataFile; std::string chapterBuffer = ""; const int buffersize = 1024; char charBuffer[buffersize]; bool foundEnd = false; dataFile = fopen("xc3_.tsc", "rt");//open data file fseek(dataFile,dataFileLoc,SEEK_SET); while(!foundEnd){ fread(charBuffer,1,buffersize,dataFile); for(int i=1; i&lt;buffersize; i++){ if(charBuffer[i] == '$'){ foundEnd = true; charBuffer[i] = '\0'; dataFileLoc = ftell(dataFile)-(buffersize-i); break;//break to spare some time } } chapterBuffer.append(charBuffer); } fclose(dataFile);//done with the file for now. checkerTemp(chapterBuffer); return chapterBuffer; } </code></pre> <p>The result should be fine. I have never reached end of file yet. so it might fail there. However, it seems to seemingly random (consistent, but at seemingly random locations). The fail would result in an injection of junk data in the string (like 8 chars worth), followed by normal data again.</p> <p>Does anyone have an idea what could cause this, or does anyone have a proper more C++ way to do this? Something with a string reader?</p> <p>Thanks in advance,</p> <p>-Smileynator</p>

    1. COCheck out [`std::getline`](http://en.cppreference.com/w/cpp/string/basic_string/getline). And of course you should learn more about the C++ [input/output facilities](http://en.cppreference.com/w/cpp/io).

    2. COUse `getline(file, data, '$')`, replace twenty lines of code with one.

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.
