GetClientRect

[binterminator]

在CMyView中调用::GetClientRect(this,&rct);为什么出错？

-------------------Configuration: OpenGL - Win32 Debug--------------------

cannot convert parameter 1 from 'class COpenGLView *const ' to 'struct HWND__ *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast


BOOL GetClientRect(
HWND hWnd, // handle to window
LPRECT lpRect // address of structure for client coordinates
);
hWnd指向视类的窗口句柄应是那个，this不对吗？？

BOOL GetClientRect(
HWND hWnd, // handle to window ，这里需要传递窗口句柄，你传递的是C++对象的指针
LPRECT lpRect // address of structure for client coordinates
);

改成::GetClientRect(this->GetSafeHwnd(),&rct);

或者this->GetClientRect(&rct);

改成::GetClientRect(m_hWnd,&rct);或者 改成::GetClientRect(&rct);
