    <p>If that's the only operation which operates on HTML code in your app, then you could use the solution I provided below (you can also test it online - <a href="http://ideone.com/ZgwLtE" rel="nofollow">here</a>). However, if you are going to do some more complicated parsing, then I suggest using some external library. </p> <pre><code>#include &lt;iostream&gt; #include &lt;cstdio&gt; #include &lt;cstring&gt; using namespace std; int main() { const char* beforePrefix = "asdfasdfasdfasdf"; const char* prefix = "&lt;!doctortype html"; const char* suffix = ".html&gt;"; const char* postSuffix = "asdasdasd"; unsigned size = 1024; char buf[size]; sprintf(buf, "%s%sTHE STRING YOU WANT TO GET%s%s", beforePrefix, prefix, suffix, postSuffix); cout &lt;&lt; "Before: " &lt;&lt; buf &lt;&lt; endl; const char* firstOccurenceOfPrefixPtr = strstr(buf, prefix); const char* firstOccurenceOfSuffixPtr = strstr(buf, suffix); if (firstOccurenceOfPrefixPtr &amp;&amp; firstOccurenceOfSuffixPtr) { unsigned textLen = (unsigned)(firstOccurenceOfSuffixPtr - firstOccurenceOfPrefixPtr - strlen(prefix)); char newBuf[size]; strncpy(newBuf, firstOccurenceOfPrefixPtr + strlen(prefix), textLen); newBuf[textLen] = 0; cout &lt;&lt; "After: " &lt;&lt; newBuf &lt;&lt; endl; } return 0; } </code></pre> <p><strong>EDIT</strong> I get it now :). You should use <code>strstr</code> to find the first occurence of the <code>prefix</code> then. I edited the code above, and updated the <a href="http://ideone.com/ZgwLtE" rel="nofollow">link</a>.</p>

    1. COwithout knowing the location of prefix and suffix i can't get the data between them so "THE STRING YOU WANT TO GET" is not possible i think you still couldn't understand my question.

Querying!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
