Print Preview Issue

Print Preview Issue

• Tanya R. - MSFT

  Ok, I see what your thinking, i have tried several ways to implement this and failed each time.
  
  CFrame::GetActiveView() What do i set this equal to   A CView  
  
  The "DYNAMIC_DOWNCAST".  This refers to a class and a pointer, I'm guessing that the pointer is the CPreviewView   So whats the class
  
  And the OnPreviewClose method, i have looked at that in the developer site but it seems to come under Visual fox pro   I'm using C++   If this is a method that can be used in C++ then how is it called   Stumped on nearly all of this
  
  
  Thanks for your help

  Thanks
  
  I've gotten it working now, I couldnt seem to get the DYNAMIC_DOWNCAST to work, it always seemed to return null no matter what.  I got round this using a flag,
  
  Thanks v. much for your help

  have tried the pView->OnPreviewClose, as well as using a number of other view pointers, but the method appears to be protected, how can i access it

  Doooh.. OK just saw the class and its methods. Sorry
  
  OK must be easier.
  Just do the following
  AfxGetMainWnd()->SendMessage(WM_COMMAND,AFX_ID_PREVIEW_CLOSE);
  Should work.

  CFrame::GetActiveView is the function to retrieve the current active View from a frame! So if you have an SDI application you can get the current active View!
  
  When the preview View is active your current View class is replaced by a CPreviewView object.
  So in short:
  DYNAMIC_DOWNCAST(CPreviewView,pView) should return a pointer to the CPreviewView class object.
  
  OnPreviewClose is no documented function. It is the implementation of the for the handler when the user presses the Close button in the preview. 
  
  Is this application MDI or SDI

  The MSDN Scribble tutorial. For me a standard sample to check MFC behaviour.

  Ok i have got it working using CMDIFrameWnd::GetActiveView
  
  But when i come to use the OnPreviewClose, I am confused as to how to use it   Are we talking just the call ie.
  
  OnPreviewClose():
  or via the pView pointer
  
  pView->OnPreviewClose();
  
  Or something entirely different
  
  Thanks for your help with this

  Get the parent frame window and the active view with CFrameWnd::GetActiveView, cast this into a CPreviewView with DYNAMIC_DOWNCAST, if the pointer is non NULL call  OnPreviewClose

  One thing i have noticed tho...the new document is loaded succesfully etc, but when you got to exit that document or minimise it the other document (window) underneath, that was previously in print preview mode is displayed without the minimise, maximise, close (X) icons that your normally have in the top right hand corner of a window.  Once you maximise that window or document the icons in the top right appear and stay with it, any ideas   Is there a way to force the showing of these icons and how would I specify that for this particular window
  
  
  Thanks

  I asked it but never get an answer
  MDI or SDI It just guess and say MDI!
  
  I just checked this with the scribble sample and it does not show this behaviour.
