C++.NET Can I use atoi ??
Hi,
I'm trying to learn C++.NET and I've got a listbox with some items in it via Properties->Collection. They're strings and I want the user to choose one of the strings in the list box and then pass that string (a number from 1 to 12) to a function that will fill another list box with data from a database according to which number was chosen. Can I just use regular atoi to convert the string or do i need to use something like
listBox1->Text...conversion... ???
Thanks for your help.

atoi only works with C-style strings. If your string is a C-style string or if it has a conversion to a C-style string (such as std::string's c_str member function) you can use atoi. Otherwise you cannot. Unfortunately, in C++ "string" can mean several mutually exclusive types, so you'll have to be more specific as to how you declare this string.
My best code is written with the delete key.
If you're using the .NET CLR you can use the Int32::Parse() method...
int MyInt = Int32::Parse("154"); // MyInt = 154
My guess is he is using the string class that is defined by Microsofts library, probably System::String. Only a guess though.
