1.Passing by parameter ensures, you don't create multiple copies.
2.As you don't make copies, it saves memory and be faster.
3.When you change something to the reference, it would mean you are changing the actual object. So serves the purpose.
4. The same can be done using pointers, but reference are better in many ways. The major advantage is that you dont need to check for NULL every time.

I have a project without document-view architecture. I added a (TableF)childframe derived from CMDIChildWnd and a (HeadView) childview derived from CView which is a member of childframe. When I execute, the childframe that is the window is been made properly with the view but the window gives debug assertion error while closing.
class TableF : public CMDIChildWnd
virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
HeadView Heading ;
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
class HeadView : public CView
HeadView(); // protected constructor used by dynamic creation
virtual void OnInitialUpdate();
virtual void OnDraw(CDC* pDC); // overridden to draw this view
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
I have a project without document-view architecture. And I wanted to ask if ChildView member of the Childframe can be derived from CView.I am deriving a childview from CView and this childview is a member of childframe . When I execute the window is opened but while closing I am getting the above error.
I have an MDI app with a docking property pane using CMFCPropertyGridCtrl. The property pane is updated with document and multiple modeless dialog property data using OnSetFocus() to populate the appropriate data depending on which document or dialog has the focus.
The problem is if I have the focus on a dialog with a document also open and want to change a property by selecting the property pane the focus is changed to the document first thus changing the property pane data to the document data.
Basically what is happening is whenever the main frame (i.e. docking pane) is selected the last document view also receives the focus (first). Is there any way to prevent the document view from receiving the focus when the docking property pane is selected?
WAVEFORMATEX structure is said to replace the old WAVEFORMAT structure. With WAVEFORMATEX for waveInOpen, the Subchunk1Size is set as 18 somewhere by the API ( ? ). And it is treated as non-PCM when Subchunk1Size is not 16. How to set the value of Subchunk1Size to 16 when I am creating a wav file? Thanks.
