窗口类中如何调用视图类

[yang0622]

TextDialog.h中的文件内容
class CProjectView;
class CTextDialog : public CDialog
{public:
CProjectView* m_pview;
}
TextDialog.cpp中的文件内容
void CTextDialog::OnChangeText()
{
m_pview->SendMessage(WM_COMMAND,ID_TEXT_MESSAGE);
}

调试错误为两个：
use of undefined type 'CProjectView'
: see declaration of 'CProjectView'

left of '->SendMessageA' must point to class/struct/union

为什么？？？？

你的CProjectView是什么？ 错误：使用了没有定义的CProjectView
还有注意MSDN中的
Constructs a CView object. The framework calls the constructor when a new frame window is created or a window is split. Override the OnInitialUpdate member function to initialize the view after the document is attached.

用GETACTIVEVIEW（）
CMDIFramwND* fram=AFXgETapp()->afxgetmainWnd()
CXVIEW *VIEW=fram->getactiveview();
VIEW->......
