MDI动态加载文档/视图问题 100分

[Biecheny]

在.dll中：
CMultiDocTemplate* Cdll009::myinit()
{
BOOL bSuccess = FALSE;
CMultiDocTemplate* pDocTemplate;
CMultiDocTemplate* pDocTemplate2;
CWinApp* pApp = AfxGetApp();
ASSERT(pApp);
if (pApp)
{
pDocTemplate = new CMultiDocTemplate(
IDR_MENU1,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMDIChildWnd),
RUNTIME_CLASS(CMyView));

pDocTemplate2 = new CMultiDocTemplate(
IDR_MENU1,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMDIChildWnd),
RUNTIME_CLASS(CMyView2));

ASSERT(pDocTemplate);
if (pDocTemplate)
{
pApp->AddDocTemplate(pDocTemplate);
bSuccess = TRUE;
}

}

return pDocTemplate2;
}

在CTest009App类中：
void CTest009App::OnNewt()
{

typedef CMultiDocTemplate* (*MYINIT)();
MYINIT fnMyinit;
FARPROC lpfn=NULL;
HINSTANCE hinst = NULL;
hinst = LoadLibrary("../dll009/Debug/dll009.dll");
if (hinst == NULL)
{
AfxMessageBox("can not load dll");
return;
}
lpfn = GetProcAddress(hinst,"myinit");
fnMyinit = (MYINIT)lpfn;


if(lpfn==NULL)
{
AfxMessageBox("can not get template");
return;
}

pDocTemplate2 = fnMyinit();

CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// Dispatch commands specified on the command line
cmdInfo.m_nShellCommand = ::CCommandLineInfo.FileNew;
if (!ProcessShellCommand(cmdInfo))
return;
//取得主框架窗口的指针
CWnd* pMainWnd = AfxGetApp()->m_pMainWnd;
CMainFrame* pMainFrame = (CMainFrame*)pMainWnd;

pMainFrame->OnTestNew();//重载的OnWindowNew()
pMainFrame->MDITile();
}

mainfrm中重载的OnWindowNew()
void CMainFrame::OnTestNew()
{

CMDIChildWnd* pActiveChild = MDIGetActive();
CDocument* pDocument;
if (pActiveChild == NULL ||
(pDocument = pActiveChild->GetActiveDocument()) == NULL)
{
TRACE0("Warning: No active document for WindowNew command.\n");
AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
return; // command failed
}

// otherwise we have a new frame !
CDocTemplate* pTemplate = ((CTest009App*) AfxGetApp())->pDocTemplate2;//pDocument->GetDocTemplate();

ASSERT_VALID(pTemplate);
CFrameWnd* pFrame = pTemplate->CreateNewFrame(pDocument, pActiveChild);
if (pFrame == NULL)
{
TRACE0("Warning: failed to create new frame.\n");
return; // command failed
}

pTemplate->InitialUpdateFrame(pFrame, pDocument);

}
=======================
问题：
在程序第一次加载dll并调用CTest009App::OnNewt()时，一切正常：先构建mainframe,然后加载dll
创建基于一个文档的2个视图，但当关闭2个视图后，在次调用CTest009App::OnNewt()出错
请高手们帮着解决一下，如何能在关闭子窗口时把程序还原成没调用dll和Cdll009::myinit()时的状态（关闭自窗口后再FreeLibrary出错）
分不够再加~

如果可以的话，可以将程序源代码发到:[e-mail]
我帮你看看！注明帖子的URL！

一楼的老兄谢了
重载了一下CDocManager问题已经解决了
