I’m programming in C++ using Visual Studio 2010 using a Windows Form to create stuff. Friggin’ hating it!
I want to use vector arrays, which I can do easily enough in a native C++ program but I can’t find any walk thru examples for use in a Form.
I’ve included cliext/vector in the main.cpp. If I try and include in the Form.h it tells me I can’t do it.
When I try and create a vector array variable it tells me I have a
syntax error missing ‘;’ before ‘<‘
All I want to do is create 6 arrays (int/float/2 Point/2 String^) that I can easily add data too then read it back later.
I just need an example of how to set it up.
[Edit]
Not sure how posting code that doesn’t work is going to help in getting a link to a working example but sure… I’ll go along with it.
Oh, if I add using namespace cliext; at the top of my .h file I’m told that cliext isn’t a class or namesapce.
The first load of errors are all about how the vector syntax is wrong…then I get a load of errors stemming from the variables being undefined later on.

If you’re not fixated on having a function called
push_back, but are ok withAdd, you can use the .NET-provided collections to store .NET data in.System::Collections::Generic::List<T>is analogous tostd::vector.System::Collections::Generic::LinkedList<T>tostd::list, andSystem::Collections::Generic::Dictionary<TKey, TValue>tostd::unordered_map.
