Print screen's of errors !

I put some animal names in the text file and read them from file into listBox's additem function one by one ;and it is going well  ... now i want to write all items of listBox into the file as you suggest me and give me piece of code ... but it's not working well , it is giving some kind of compiler/syntax error !

std::ofstream ofile("animals.txt");
if (ifile.is_open())
{
    auto& items = listBox->getItems();
    for (auto& item : items)
    {
        ofile << item.toAnsiString() << std::endl;
    }
}

   

Second solution you told me was difficult for me to code .. i have to complete this assignment as soon as possible .. is there any way other then file handling! ?
You can see in my above code i tried it (reading/writing from file i.e. file handling).. But it was not running well!

sorry i wrote it little bit wrong i should have ask like this "can i store the animal name written in editBox in a string and then pass this string to addItem() function of listBox so that it may be permanently store in the listBox as an item" !
I do it like this in my code , but its not saving the item in the listBox permanently i.e. when compiling my code second time the newly added animal name disappears from listBox ! ...

can i store the selected item from listBox in a character array or any character variable so that i may pass this character array in addItem() function of listBox, and it will store new animal name in the listBox !?

hmmm, i didn't get you !

what i am doing wrong here, i am adding the new animal in the edit box and when press add animal button it will be added in the list (good with it !) but when i close my window and compile my code again it will not show the recently added animal in the list box !
