如何在对话框类中调用文档类的成员

[Saint_ET]

写了一个StudentData的类，并在StudentData.h中声明
typedef CArray<StudentData,StudentData&> StuArray;
然后在CMyDoc中定义了数组
public:
StuArray arr;
怎么在对话框中使用此数组？

给你一种MDI和SDI通用的办法：
CFrameWnd* pMainFrame=(CFrameWnd*)AfxGetMainWnd();
CFrameWnd* pActiveFrame=pMainFrame->GetActiveFrame();
CDocument* pActiveDocument=pActiveFrame->GetActiveDocument();
if(pActiveDocument)
{
………………
}

CFrameWnd *pWnd =(CFrameWnd *)AfxGetMainWnd();
CMyDoc *pDoc=(CMyDoc *)pWnd->GetActiveDocument();
pDoc->arr.???

[nuaawyd]

CMyDoc* pDoc = GetDocument();

[pcman1990]

CWnd *pWnd = AfxGetMainWnd();
CView *pView = pWnd->GetActiveView();
if(pView != NULL)
{
CMyDoc *pDoc = (CMyDoc *)pView->GetDocument();
// then you can use pDoc->arr
}

[pcman1990]

写错一点点，应该是：
CFrameWnd *pWnd = (CFrameWnd *)AfxGetMainWnd();
CView *pView = pWnd->GetActiveView();
if(pView != NULL)
{
CMyDoc *pDoc = (CMyDoc *)pView->GetDocument();
// then you can use pDoc->arr
}

[Lemon_2000]

CFrameWnd *pWnd = (CFrameWnd *)AfxGetMainWnd();
CMyDoc *pDoc= pWnd->GetActiveDocument();

这些写在dialog.cpp中吗？如果要使用数组的话
是不是pDoc->arr[i].***啊

#include "mainfrm.h"
CMainFrame *pWnd = (CMainFrame*)AfxGetMainWnd();
CMyView *pView = pWnd->GetActiveView();
if(pView != NULL)
{
CMyDoc *pDoc = (CMyDoc *)pView->GetDocument();
}

[Saint_ET]

CStudentView *pView = pWnd->GetActiveView();
还是不行
error C2440: 'initializing' : cannot convert from 'class CView *' to 'class CStudentView *'

该CFrameWnd指的是CMainFrame!
