Body
I am trying to use "map" container in C++ in the following way: <ul> <li>Key is a string and mapping value is an object of type ofstream. If I execute the following code, I get an error that is copied at the end of the message. Could someone please let me know what is going wrong? If it can not be done using 'map' is there some other way to create such key:value pair? I would appreciate your response. </li> </ul> Note: If I test the following code with map foo; it works fine. Code: <pre><code>#include <string> #include <iostream> #include <map> #include <fstream> using namespace std; int main() { // typedef map<string, int> mapType2; // map<string, int> foo; typedef map<string, ofstream> mapType; map<string, ofstream> fooMap; ofstream foo1; ofstream foo2; fooMap["file1"] = foo1; fooMap["file2"]= foo2; mapType::iterator iter = fooMap.begin(); cout<< "Key = " <<iter->first; } </code></pre> Error: <pre><code>C:/Dev-Cpp/bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/ios_base.h: In member function `std::basic_ios<char, std::char_traits<char> >& std::basic_ios<char, std::char_traits<char> >::operator=(const std::basic_ios<char, std::char_traits<char> >&)': C:/Dev-Cpp/bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/ios_base.h:741: error: `std::ios_base& std::ios_base::operator=(const std::ios_base&)' is private hash.cpp:88: error: within this context </code></pre>

1. COAs a style aside, you can define fooMap as mapType e.g. mapType fooMap; since you have already typedefed it.

Guidance

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.
