How do I make a vector/array of System::Windows::Forms::Checkbox^

问题

Couldn't find any answer to this problem, or not even any questions asked. So what I'm trying to do, is a std::vector, maybe just a normal array, of Checkboxes.

std::vector< System::Windows::Forms::CheckBox^ >m_items;
m_items.push_back( myCheckbox );

That's what I currently have, and it clearly ain't working. So does anyone have any ideas, on how to get it working, cause I've tried everything I can, but vectors don't seem to support Checkboxes.

Incase you need the error code:

回答1:

The regular std::vector does not support CLR reference types. Instead, you must use cliext::vector. Include the following:

#include <cliext/vector>

And use with:

cliext::vector<System::Windows::Forms::CheckBox^> items;
items.push_back(myCheckBox);

Of course, you can also use the regular .Net collections, like List<T>, which behaves similarly as a vector.
