  1. The warning C4244 is because you assigned the outcome of DoModal to an int and /Wp64 is assigned. In a 64bit environment the return value is 64bit nut int is always 32bits. Either remove /Wp64 or use INT_PTR as a type for nRetInit or write
  if (InitSetup.DoModal()==IDOK)
  {
  ...
  }
  It's not wise to use 1 instead of IDOK.

  2. Invalidate and UpdateWindow are no members of the document. In a Document you should use UpdateAllViews(NULL); This should update the View.

  My tip for you: Read a book about MFC programming!

  And what is inside ConfigureApp.m_strIPRangeFrom

  Set a breakpint and check it contents!

  Also it seams tsrange to me that you have absolute coordinates to show the data! If your view is to small you see nothing.

  You have to invalidate the view and not the display of the dialog.

  In the view you are calling the dialog with a DoModal call. Check if the result is IDOK if so invalidate the view.

  Or from were do you call/launch the dialog

  Hi Martin,

  this is the code i have used

  void CFYPV15Doc::OnSetup()

  {

  // TODO: Add your command handler code here

  INT_PTR nRetInit = ConfigureApp.DoModal();

  if (nRetInit == IDOK)

  {

  UpdateAllViews(NULL);

  }

  }

  in the ondraw function i am using this

  pDC->TextOut(50, 432, pDoc->ConfigureApp.m_strIPRangeFrom);

  however nothing is being displayed in the view.

  thanks for your tip i have ordered a MFC book :)

  sorry to both you with these questions.

  Martin :)

  Hi Martin,

  I launch the dialog from the Doc class, is this the correct thing to do, i tried putting this into the launch of the dialog:

  int nRetInit = InitSetup.DoModal();
  
  if(nRetInit == 1)
  {
  Invalidate(TRUE);
  UpdateWindow();
  }

  but i get these errors:

  warning C4244: 'initializing' : conversion from 'INT_PTR' to 'int', possible loss of data

  error C3861: 'Invalidate': identifier not found, even with argument-dependent lookup

  error C2660: 'UpdateWindow' : function does not take 0 arguments

  i'm not sure what to do at this point

  thank you for your help

  Martin :)

  Hi Martin,

  thanks for all your help, it is now working and redrawing the views, i added

  SetModifiedFlag(TRUE);

  just prior to the UpdateAllViews and it seems to be working fine now.

  thank you for all your help with this

  Kindest regards

  Martin :)

  The location is fine as i have other stuff marked absolute which is visable, o for now i know that it should be showing up its just not :(

  the info within the m_strIPRangeFrom i believe is there as i am able to serialize this information and it is stored within the saved file when opening with notepad or loading it back into the doc.

  thanks for your help so far :)
