multi-view in an sdi

I have 4 daorecordviews set up in the init of the app
ex : m_mydoctemp[0] =
CmultiDocTemplate = {menu, doc1, mainframe, view1)
adddoctemp ...
m_mydoctemp[1] =
CmultiDocTemplate = {menu, doc2, mainframe, view2)
adddoctemp ...
the app is designed as a SDI. I want to be able to show different views with there document data when a menu selection is choosen.
Replace one view with the other.  Where do I go from here?

Basically, you will need to write a function in the mainframe to do this:

 CMainFrame::SwitchToView(int view)
 {
   CView* oldView = GetActiveView();
   CView* newView = NULL;
   switch (view)
   {
     case view1:
       newView = new CView1;
       break;
     case view2:
       newView = new CView2;
       break;
   }

   CCreateContext context;

   // Set up document. This assumes current doc. But if you have
   // new document, then you can create it here
   context.m_pCurrentDoc = pOldView->GetDocument();
   newView->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, this, view, &context);
   newView->OnInitialUpdate();
   SetActiveView(newView);
   newView->ShowWindow(SW_SHOW);
   oldView->ShowWindow(SW_HIDE);
   RecalcLayout();
 }

I think this the right way to go.  However, I tried this last night and Kept recieving an access violation when trying to Create.  I did change the templates back to CSingleDocTemplate,  the Frame is based on CFrameWin.  I had to change the menu resorce in three of the templates to force the NEW window to stop displaying on startup.  I tried changing the sting resource to achieve this but could not get it to start with the first template.  The views and documents I'm trying to create and open are based off of the DAO database classes.

Dear thui, You had given a very good explanation for SDI.But I am asking the same question for MDI.ie., How can I associate a each document to each view (One document for one view). I Expect the very best answer from you !.

You must make up a document for each view and create a document template for each pair in the init functuion of your app.
Once this is done you can make a call in your program to change the template thus change the view and document pointer.  I don't have the exact code with me right now.  But that's the jist of it.  The templates must be based off of CMultiDocTemplate.

Yes Sas.As you said , I made a document template for the view in the app. But I didn't get which call is to be placed in my program to change the template to change the view and document pointer. Also please let me know where I can call that !.
