    <p>I am writing a simple program, which is trying to find next palindrome number after given number.</p> <p>As for now, I am stuck at this point:</p> <pre><code>string::iterator iter; // iterators for the string string::iterator riter; //testcases is a vector&lt;string&gt; with strings representing numbers. for (unsigned int i = 0; i &lt; testcases.size() ; ++i) { iter = testcases[i].begin(); riter = testcases[i].end(); while ( !isPalin(testcases[i]) ) { //isPalin(string) is a function //which is checking if given string //is a palindrome //if n-th digit from the end is different from the //n-th digit, then I want to replace latter one, so they will //be the same. if ( *iter != *riter ) { testcases[i].replace(riter, riter, *iter); } ++iter; // advancing forward iterator; --riter; // advancing backward iterator; } cout &lt;&lt; testcases[i] &lt;&lt; " -&gt; ok\n"; } </code></pre> <p>When I am compiling this one using Microsoft Visual Studio 2008, I am getting this error:</p> <pre><code>Compiling... main.cpp .\main.cpp(53) : error C2664: 'std::basic_string&lt;_Elem,_Traits,_Ax&gt; &amp;std::basic_string&lt;_Elem,_Traits,_Ax&gt;::replace(unsigned int,unsigned int,const std::basic_string&lt;_Elem,_Traits,_Ax&gt; &amp;)' : cannot convert parameter 1 from 'std::_String_iterator&lt;_Elem,_Traits,_Alloc&gt;' to 'unsigned int' with [ _Elem=char, _Traits=std::char_traits, _Ax=std::allocator ] and [ _Elem=char, _Traits=std::char_traits, _Alloc=std::allocator ] No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called </code></pre> <p>Am I doing something stupid or am I missing something? I would be grateful for any help / suggestion.</p>

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.
