Replace a view in a splitter

// My problem is I don't have the pContext

Do you have a NULL-pointer ? :)

...or a pointer to a temp instance:

{
  CCreateContext sContext = {0};
  //..
}

I found this

http://www.codeguru.com/cpp/w-d/splitter/article.php/c1533[^]

it works, except for the document, I have a null pointer when I try to retreive it, but anyway using NULL as document everything works.

CDocTemplate *pAmortDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CView1)); //change the class with the view you want to be displayed as default
//you can extend this so the program saves the active view (not the view J , only information about which one was active), and you can
//restore the last one when the program will start again
AddDocTemplate(pAmortDocTemplate);
