C++

Rect m_rect

C++

Error:identifier "Rect" is undifined

The question makes no sense. You did not specify platform, language and the library you want to use. Your lack of understanding of what you need to specify tells me that you cannot use the libraries and find proper documentation. So, practically, you should not be doing what you are doing. You should get back and learn the very basics of programming, your platforms and language. Start with the very basics, I'm sure you really need that.

Solution 1

You probably wanted to use the CRect class.

Note that all MFC class names begin with an uppercase 'C' letter.
